MPlayer(1) MPlayer(1) NAME mplayer - Movie Player for Linux mencoder - Movie Encoder for Linux SYNOPSIS mplayer [options] [ file | URL | playlist | - ] mplayer [global options] file1 [specific options] [file2] [specific options] mplayer [global options] {group of files and options} [group specific options] mplayer [dvd|vcd|cdda|cddb|tv]://title [options] mplayer [mms[t]|http|http_proxy|rt[s]p]:// [user:passwd@]URL[:port] [options] mencoder [options] [ file | URL | - ] [-o file] gmplayer [options] [-skin skin] DESCRIPTION mplayer is a movie player for LINUX (runs on many other Unices and non-x86 CPUs, see the documentation). It plays most MPEG/VOB, AVI, ASF/WMA/WMV, RM, QT/MOV/MP4, OGG/OGM, VIVO, FLI, NuppelVideo, yuv4mpeg, FILM and RoQ files, sup- ported by many native, XAnim, and Win32 DLL codecs. You can watch VideoCD, SVCD, DVD, 3ivx, DivX 3/4/5 and even WMV movies, too (without using the avifile library). Another great feature of MPlayer is the wide range of sup- ported output drivers. It works with X11, XV, DGA, OpenGL, SVGAlib, fbdev, AAlib, DirectFB, but you can also use GGI, SDL (and this way all their drivers), VESA (on every VESA compatible card, even without X11), some low level card-specific drivers (for Matrox, 3Dfx and ATI) and some hardware MPEG decoder boards, such as the Siemens DVB, DXR2 and DXR3/Hollywood+. Most of them support soft- ware or hardware scaling, so you can enjoy movies in fullscreen. MPlayer has an onscreen display (OSD) for status informa- tion, nice big antialiased shaded subtitles and visual feedback for keyboard controls. European/ISO 8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean fonts are supported along with 10 subtitle formats (Mi- croDVD, SubRip, SubViewer, Sami, VPlayer, RT, SSA, AQTi- tle, JACOsub and our own: MPsub) and DVD subtitles (SPU streams, VobSub and Closed Captions). mencoder (MPlayer's Movie Encoder) is a simple movie en- coder, designed to encode MPlayer-playable movies (see above) to other MPlayer-playable formats (see below). It encodes to DivX4, XviD, one of the libavcodec codecs and PCM/MP3/VBRMP3 audio in 1, 2 or 3 passes. Furthermore it has stream copying abilities, a powerful plugin system (crop, expand, flip, postprocess, rotate, scale, noise, rgb/yuv conversion) and more. gmplayer is MPlayer with a graphical user interface. It has the same options as MPlayer. GENERAL NOTES Also see the HTML documentation! Every 'flag' option has a 'noflag' counterpart, e.g. the opposite of the -fs option is -nofs. You can put all of the options in a configuration file which will be read every time mplayer is run. The system- wide configuration file 'mplayer.conf' is in your configu- ration directory (e.g. /etc/mplayer or /usr/local/etc/ mplayer), the user specific one is '~/.mplayer/config'. User specific options override system-wide options and op- tions given on the command line override either. The syn- tax of the configuration files is 'option=', every- thing after a '#' is considered a comment. Options that work without values can be enabled by setting them to 'yes' or '1' and disabled by setting them to 'no' or '0'. Even suboptions can be specified in this way. EXAMPLE: # Use Matrox driver by default. vo=xmga # I love practicing handstands while watching videos. flip=yes # Decode/encode multiple files from png, start with -mf on mf= type=png:fps=25 You can also write file-specific configuration files. If you wish to have a config file for a file called 'movie.avi', create a file named 'movie.avi.conf' with the file-specific options in it and put it in ~/.mplayer or in the same directory as the file. PLAYER OPTIONS (MPLAYER ONLY) -, -use-stdin Read data from stdin. The -idx option does not work in conjunction with this. -autoq (use with -vop pp) Dynamically changes the level of postprocessing de- pending on available spare CPU time. The number you specify will be the maximum level used. Usual- ly you can use some big number. You have to use -vop pp without parameters in order to use this. -autosync Gradually adjusts the A/V sync based on audio delay measurements. Specifying -autosync 0, the default, will cause frame timing to be based entirely on au- dio delay measurements. Specifying -autosync 1 will do the same, but will subtly change the A/V correction algorithm used. An uneven video frame rate in a movie which plays fine with -nosound can often be helped by setting this to an integer value greater than 1. The higher the value, the closer the timing will be to -nosound. Try -autosync 30 to smooth out problems with sound drivers which do not implement a perfect audio delay measurement. With this value, if large A/V sync offsets occur, they will only take about 1 or 2 seconds to settle out. This delay in reaction time to sudden A/V offsets should be the only side-effect of turning this option on, for all sound drivers. -benchmark Prints some statistics on CPU usage and dropped frames at the end. Use in combination with -nosound and -vo null for benchmarking only the video codec. -edl Enables edit decision list (EDL) actions during playback. Video will be skipped over and audio will be muted and unmuted according to the entries in the given file. See DOCS/documentation.html#edl for details on how to use this. -edlout Creates a new file and writes edit decision list (EDL) records to that file. During playback, when the user hits 'i', an entry to skip over the last two seconds of playback will be written to the file. This provides a starting point from which the user can fine-tune EDL entries later. See DOCS/documentation.html#edl for details. -enqueue (GUI only) Enqueue files given on the command line in the playlist instead of playing them immediately. -fixed-vo (BETA CODE!) Enforces a fixed video system for multiple files (one (un)initialisation for all files). Therefore only one window will be opened for all files. Cur- rently the following drivers are fixed-vo compli- ant: x11, xv, xvidix, xmga, gl2, and svga. -framedrop (also see -hardframedrop) Skip displaying some frames to maintain A/V sync on slow systems. Video filters are not applied to such frames. For B frames even decoding is skipped completely. -h, -help, --help Show short summary of options. -hardframedrop More intense frame dropping (breaks decoding). Leads to image distortion! -identify Show file parameters in easy parsable format. The wrapper script TOOLS/midentify suppresses the other mplayer output and (hopefully) shellescapes the filenames. -input This option can be used to configure certain parts of the input system. Paths are relative to ~/ .mplayer/. NOTE: Autorepeat is currently only supported by joy- sticks. Available commands are: conf= Read alternative input.conf. If given without pathname, ~/.mplayer is assumed. ar-delay Delay in msec before we start to autorepeat a key (0 to disable). ar-rate How many key presses per second when we autorepeat. keylist Prints all keys that can be bound. cmdlist Prints all commands that can be bound. js-dev Specifies the joystick de- vice to use (default is /dev/input/js0). file Read commands from the given file. Mostly useful with a fifo. -lircconf Specifies a configuration file for LIRC (Linux In- frared Remote Control, see http://www.lirc.org) if you don't like the default ~/.lircrc. -loop Loops movie playback times. 0 means for- ever. -menu (BETA CODE) Turn on OSD menu support. -menu-root (BETA CODE) Specify the main menu. -menu-cfg (BETA CODE) Use an alternative menu.conf. -nojoystick Turns off joystick support. Default is on, if com- piled in. -nolirc Turns off LIRC support. -nortc Turns off usage of the Linux RTC (real-time clock - /dev/rtc) as timing mechanism. -playlist Play files according to a playlist (1 file per row or Winamp or ASX format). -quiet Display less output and status messages. -really-quiet Display even less output and status messages. -sdp Specifies that the input file is a SDP ('Session Description Protocol') file that describes an RTP session (see http://www.live.com/mplayer/). -shuffle Play files in random order. -skin (BETA CODE) Load skin from the given directory (WITHOUT path name). EXAMPLE: -skin fittyfene tries Skin/fittyfene. It first checks /usr/lo- cal/share/mplayer/ and af- terwards ~/.mplayer/. -slave This option switches on slave mode. This is in- tended for use of MPlayer as a backend to other programs. Instead of intercepting keyboard events, MPlayer will read simplistic command lines from its stdin. The section SLAVE MODE PROTOCOL explains the syntax. -softsleep Uses high quality software timers. As precise as the RTC without requiring special privileges. Comes at the price of higher CPU consumption. -speed <0.01-100> Set playback speed rate. -sstep Specifies seconds between displayed frames. Useful for slideshows. DEMUXER/STREAM OPTIONS -aid (also see -alang option) Select audio channel [MPEG: 0-31 AVI/OGM: 1-99 ASF/ RM: 0-127 VOB(AC3): 128-159 VOB(LPCM): 160-191] MPlayer prints the available IDs when running in verbose (-v) mode. -alang (also see -aid option) Works only for DVD playback. It selects the DVD audio language and always tries to play audio streams whose language matches the given code. For the list of available languages, use with the -v option and look at the output. EXAMPLE: -alang hu,en Plays Hungarian and falls back to English if Hungarian is not available. -audio-demuxer (-audiofile only) Force audio demuxer type for -audiofile. Give the demuxer ID as defined in demuxers.h. Use -au- dio-demuxer 17 to force .mp3 detection. -audiofile Play audio from an external file (WAV, MP3 or Ogg Vorbis) while viewing a movie. -bandwidth Specify the maximum bandwidth for network streaming (for servers that are able to send content in dif- ferent bitrates). Usefull if you want to watch live streamed media behind a slow connection. -cdrom-device Override default CDROM drive name /dev/cdrom. -cache This option specifies how much memory (in kbytes) to use when precaching a file/URL. Especially use- ful on slow media (default is -nocache). -cdda This option can be used to tune the CD Audio read- ing feature of MPlayer. Available options are: speed= set CD spin speed paranoia=<0-2> set paranoia level 0: disable checking 1: overlap checking only (default) 2: full data correction and verification generic-dev= use specified generic SCSI device sector-size= atomic read size overlap= force minimum overlap search during verification to sectors. toc-bias Assume that the beginning offset of track 1 as report- ed in the TOC will be ad- dressed as LBA 0. Some Toshiba drives need this for getting track boundaries correct. toc-offset= Add sectors to the values reported when ad- dressing tracks. May be negative. (no)skip (never) accept imperfect da- ta reconstruction. -channels Change the number of playback channels, defaults to '2' if not specified. If the number of output channels is bigger than the number of input chan- nels empty channels are inserted (unless mixing from mono to stereo, then the mono channel is re- peated in both output channels). If the number of output channels is smaller than the number of input channels, results depend on the audio decoder (-afm). MPlayer asks the decoder to decode the au- dio into as many channels as specified. Now it's up to the decoder to fulfill the requirement. If the decoder outputs more channels than requested, the exceeding channels are truncated. This is usu- ally only important when playing videos with AC3 audio (like DVDs). In that case liba52 does the decoding by default and correctly downmixes the au- dio into the requested number of channels. NOTE: This option is honored by codecs (AC3 only) filters (surround) and ao drivers (OSS at least). Available options are: 2 Stereo 4 Surround 6 Full 5.1 -chapter [-] Specify which chapter to start playing at. Option- ally specify which chapter to end playing at (de- fault: 1). Examples can be found below. -csslib (old-style DVD option) This option is used to over- ride the default location of libcss.so. -cuefile (see -vcd too) Play (S)VCD from CDRwin's (bin/cue fileformat) disk image, described by the specified file. -demuxer Force demuxer type. Give the demuxer ID as defined in demuxers.h. Use -demuxer 17 to force .mp3 de- tection. -dumpaudio (MPLAYER only) Dumps raw compressed audio stream to ./stream.dump (useful with mpeg/ac3). -dumpfile (MPLAYER only) Specify which file MPlayer should dump to. Should be used together with -dumpaudio / -dumpvideo / -dumpstream. -dumpstream (MPLAYER only) Dumps the raw stream to ./stream.dump. Useful when ripping from DVD or network. -dumpvideo (MPLAYER only) Dump raw compressed video stream to ./stream.dump (not very usable). -dvd Tell MPlayer which movies (specified by title id) to play. For example sometimes '1' is a trailer, and '2' is the real movie. NOTE: Sometimes deinterlacing is required for DVD play- back, see the -vop pp=0x20000 option. -dvd-device <path to device> Override default DVD device name /dev/dvd. -dvdangle <angle id> Some DVD discs contain scenes that can be viewed from multiple angles. Here you can tell MPlayer which angles to use (default: 1). Examples can be found below. -dvdauth <DVD device> (old-style DVD option) Turns on DVD authentication using the given device. -dvdkey <CSS key> (old-style DVD option) When decoding a VOB file copied undecrypted from DVD, this option gives the CSS key needed to decrypt the VOB (the key is printed when authenticating with the DVD drive us- ing -dvdauth). -dvdnav (BETA CODE!) Force usage of libdvdnav. -forceidx Force rebuilding of INDEX. Useful for files with broken index (desyncs, etc). Seeking will be pos- sible. You can fix the index permanently with MEn- coder (see the documentation). -fps <value> Override video framerate (if value is wrong/missing in the header) (float number). -frames <number> Play/convert only first <number> frames, then quit. -hr-mp3-seek (.MP3 only) Hi-res mp3 seeking. Default is: enabled when play- ing from external MP3 file, as we need to seek to the very exact position to keep A/V sync. It can be slow especially when seeking backwards - it has to rewind to the beginning to find the exact frame. -idx (also see -forceidx) Rebuilds INDEX of the AVI if no INDEX was found, thus allowing seeking. Useful with broken/incom- plete downloads, or badly created AVIs. -mc <seconds/frame> Maximum A-V sync correction per frame (in seconds). -mf <option1:option2:...> Used when decoding from multiple PNG or JPEG files. Available options are: on turns on multifile support w=<value> width of the output (autode- tect) h=<value> height of the output (au- todetect) fps=<value> fps of the output (default: 25) type=<value> type of input files (avail- able types: jpeg, png, tga, sgi) -ni (.AVI only) Force usage of non-interleaved AVI parser (fixes playing of some bad AVI files). -nobps (.AVI only) Do not use average byte/sec value for A-V sync (AVI). Helps with some AVI files with broken head- er. -noextbased Disables filename-extension based demuxer selec- tion. By default, when file type (demuxer) cannot be detected reliably (the file has no header or it is not reliable enough), the filename extension is used to select demuxer. It always falls back to content-based demuxer selection. -passwd <password> (see -user option too) Specify password for http authentication. -rawaudio <option1:option2:...> This option lets you play raw audio files. It may also be used to play audio CDs which are not 44KHz 16Bit stereo. Available options are: on use raw audio demuxer channels=<value> number of channels rate=<value> rate in samples per second samplesize=<value> sample size in byte format=<value> fourcc in hex -rawvideo <option1:option2:...> This option lets you play raw video files. Available options are: on use raw video demuxer fps=<value> rate in frames per second, default 25.0 sqcif|qcif|cif|4cif|pal|ntsc set standard image size w=<value> image width in pixels h=<value> image height in pixels y420|yv12|yuy2|y8 set colorspace format=<value> colorspace (fourcc) in hex size=<value> frame size in bytes -rtsp-stream-over-tcp Used with 'rtsp://' URLs to specify that the re- sulting incoming RTP and RTCP packets be streamed over TCP (using the same TCP connection as RTSP). This option may be useful if you have a broken In- ternet connection that does not pass incoming UDP packets (see http://www.live.com/mplayer/). -skipopening Skip DVD opening (dvdnav only). -sb <byte position> (see -ss option too) Seek to byte position. Useful for playback from CDROM images / .VOB files with junk at the begin- ning. -srate <Hz> Forces the given audio playback rate, changing video speed to keep a-v sync. MEncoder passes this value to lame for resampling. -ss <time> (see -sb option too) Seek to given time position. EXAMPLE: -ss 56 seeks to 56 seconds -ss 01:10:00 seeks to 1 hour 10 min -tv <option1:option2:...> This option enables the TV grabbing feature of MPlayer. NOTE: MPlayer doesn't accept colons so type dots instead in the device ID (e.g. hw.0,0 instead of hw:0,0). Be advised that although you can select any sam- plerate when using ALSA, the LAME audio codec is able to encode only the 'standard' samplerates. You'll get an .avi file with no sound when you choose an odd samplerate and use this codec. Available options are: on use TV input noaudio no sound driver=<value> available: dummy, v4l, bs- dbt848 device=<value> Specify other device than the default /dev/video0. input=<value> Specify other input than the default 0 (Television) (see output for a list) freq=<value> Specify the frequency to set the tuner to (e.g. 511.250). Not compatible with channels parameter. outfmt=<value> output format of the tuner (yv12, rgb32, rgb24, rgb16, rgb15, uyvy, yuy2, i420) width=<value> width of the output window height=<value> height of the output window fps=<value> framerate at which to cap- ture video (frames per sec- ond) buffersize=<value> maximum size of the capture buffer in megabytes (de- fault: dynamical) norm=<value> available: PAL, SECAM, NTSC channel=<value> Set tuner to <value> chan- nel. chanlist=<value> available: europe-east, eu- rope-west, us-bcast, us-ca- ble, etc channels=<channel>-<name>,<channel>-<name>,... Set names for channels. Use _ for spaces in names (or play with quoting ;-). The channel names will then be written using OSD, and the commands tv_step_channel, tv_set_channel and tv_last_channel will then be usable using a remote (see lirc). Not compatible with frequency parameter. Warn- ing: The channel number will then be the position in the 'channels' list, beginning with 1. Example: use tv://1, tv://2, tv_set_chan- nel 1, tv_set_channel 2, etc. audiorate=<value> set audio capture bitrate forceaudio capture audio even if there are no audio sources report- ed by v4l alsa capture from ALSA amode=<0-3> choose an audio mode: 0: mono 1: stereo 2: language 1 3: language 2 forcechan=<1-2> By default, the count of recorded audio channels is determined automatically by querying the audio mode from the tv card. This option allows to force stereo/mono recording regardless of the amode option and the values returned by v4l. This can be used for troubleshooting when the tv card is unable to report the current audio mode. adevice=<value> set an audio device /dev/... for OSS hardware ID for ALSA audioid=<value> choose an audio output of the capture card, if it has more of them [volume|bass|treble|balance]=<0-65535> These options set parameters of the mixer on the video capture card. They will have no effect, if your card doesn't have one. immediatemode=<bool> A value of 0 means capture and buffer audio and video together (default for men- coder). A value of 1 (de- fault for mplayer) means to do video capture only and let the audio go through a loopback cable from the TV card to the soundcard. -user <user name> (see -passwd option too) Specify user name for http authentication. -vcd <track> Play video CD track from a device or image file (see -cuefile). -vid <id> Select video channel [MPG: 0-15 ASF: 0-255]. -vivo <sub-options> (DEBUG CODE) Force audio parameters for the .vivo demuxer (for debugging purposes). OSD/SUB OPTIONS NOTE: See -vop expand too. -dumpmicrodvdsub (MPLAYER only) Convert the given subtitle (specified with the -sub option) to the MicroDVD subtitle format. Creates a dumpsub.sub file in the current directory. -dumpmpsub (MPLAYER only) Convert the given subtitle (specified with the -sub option) to MPlayer's subtitle format, MPsub. Cre- ates a dump.mpsub file in the current directory. -dumpsrtsub (MPLAYER only) Convert the given subtitle (specified with the -sub option) to the time-based SubViewer (SRT) subtitle format. Creates a dumpsub.srt file in the current directory. -dumpjacosub (MPLAYER only) Convert the given subtitle (specified with the -sub option) to the time-based JACOsub subtitle format. Creates a dumpsub.js file in the current directory. -dumpsami (MPLAYER only) Convert the given subtitle (specified with the -sub option) to the time-based SAMI subtitle format. Creates a dumpsub.smi file in the current directo- ry. -dumpsub (MPLAYER only) (BETA CODE) Dumps the subtitle substream from VOB streams. See -dump*sub and -vobsubout* options too. -ifo <vobsub ifo file> Indicate the file that will be used to load palette and frame size for VOBSUB subtitles. -ffactor <number> Resample alphamap of the font. Can be: 0 plain white fonts 0.75 very narrow black outline (default) 1 narrow black outline 10 bold black outline -font <path to font.desc file> Search for the OSD/SUB fonts in an alternative di- rectory (default for normal fonts: ~/.mplayer/font/ font.desc, default for FreeType fonts: ~/.mplayer/ subfont.ttf). NOTE: With FreeType, this option determines path to the text font file. The -subfont-* options are available only with FreeType support compiled in. EXAMPLE: -font ~/.mplayer/arial-14/font.desc -font ~/.mplayer/arialuni.ttf -noautosub Turns off automatic loading of subtitle files. -overlapsub Enables overlapping subtitles support for all sub- titles formats. -nooverlapsub Disables overlapping subtitles support for all sub- titles formats (default behaviour is to enable the support only for specific formats). -osdlevel <0-3> (MPLAYER only) Specifies which mode the OSD should start in. 0 subtitles only 1 volume + seek (default) 2 volume + seek + timer + per- centage 3 volume + seek + timer + per- centage + total time -sid <id> (also see -slang option) Turns on DVD subtitle displaying. Also, you MUST specify a number which corresponds to a DVD subti- tle language (0-31). For the list of available subtitles, use with the -v option and look at the output. -slang <two letter country code> (also see -sid option) Works only for DVD playback. Turns on/selects DVD subtitle language. For the list of available sub- titles, use with the -v option and look at the out- put. EXAMPLE: -slang hu,en Selects Hungarian and falls back to English if Hungarian is not available. -sub <subtitle file> Use/display this subtitle file. -sub-bg-alpha <0-255> Specify the alpha channel value for subtitles and OSD backgrounds. Big values mean more transparen- cy. The 0 value is an exception and means complet- ly transparent. -sub-bg-color <0-255> Specify the color value for subtitles and OSD back- grounds. Currently subtitles are grayscale so this value is equivalente to the intensity of the color. The 255 value means white and 0 black. -subcc Display DVD Closed Caption (CC) subtitles. These are NOT the VOB subtitles, these are special ASCII subtitles for the hearing impaired encoded in the VOB userdata stream on most region 1 DVDs. CC sub- titles have not been spotted on DVDs from other re- gions so far. -subcp <codepage> If your system supports iconv(3), you can use this option to specify codepage of the subtitle. EXAMPLE: -subcp latin2 -subcp cp1250 -sub-demuxer <number> (BETA CODE) Force subtitle demuxer type for -subfile. -subdelay <sec> Delays subtitles by <sec> seconds. Can be nega- tive. -subfont-autoscale <0-3> Sets the autoscale mode. NOTE: Zero means that text-scale and osd-scale are font heights in points. The mode can be: 0 no autoscale 1 proportional to movie height 2 proportional to movie width 3 proportional to movie diago- nal (default) -subfont-blur <0-8> Sets the font blur radius (default: 2). -subfont-encoding <value> Sets the font encoding. When set to 'unicode', all the glyphs from the font file will be rendered and unicode will be used (default: unicode). -subfont-osd-scale <0-100> Sets the osd elements autoscale coefficient (de- fault: 6). -subfont-outline <0-8> Sets the font outline thickness (default: 2). -subfont-text-scale <0-100> Sets the subtitle text autoscale coefficient (per- centage of the screen size) (default: 5). -subfps <rate> Specify frame/sec rate of subtitle file (float num- ber), default: the same fps as the movie. NOTE: ONLY for frame-based SUB files, i.e. NOT MicroDVD format. -subfile <filename> (BETA CODE) Currently useless. Same as -audiofile, but for subtitle streams (OggDS?). -subpos <0-100> (useful with -vop expand) Specify the position of subtitles on the screen. The value is the vertical position of the subtitle in % of the screen height. -subalign <0-2> Specify how subtitles should be aligned with sub- pos. 0 means align at top (original/default behav- ior), 1 means align at center, and 2 means align at bottom. -subwidth <10-100> Specify the maximum width of subtitles on the screen. Useful for TV-out. The value is the width of the subtitle in % of the screen width. -unicode Tells MPlayer to handle the subtitle file as UNI- CODE. -utf8 Tells MPlayer to handle the subtitle file as UTF8. -sub-no-text-pp Disables any kind of text post processing done af- ter loading the subtitles. Used for debug purpos- es. -vobsub <vobsub file without extension> Specify the VobSub files that are to be used for subtitle. This is the full pathname without exten- sions, i.e. without the '.idx', '.ifo' or '.sub'. -vobsubid <0-31> Specify the VobSub subtitle id. -spualign <-1-2> Specify how spu (DVD/VobSub) subtitles should be aligned. Values are the same as for -subpos, with the extra choice -1 for original position. -spuaa <mode> Antialiasing/scaling mode for DVD/VobSub. A value of 16 may be added to mode in order to force scal- ing even when original and scaled frame size al- ready match, for example to smooth subtitles with the gaussian blur. The available modes are: 0 none (fastest, very ugly) 1 approximate (broken?) 2 full (slow) 3 bilinear (default, fast and not too bad) 4 uses swscaler gaussian blur (looks very good) -spugauss <0.0-3.0> Variance parameter of gaussian used by -spuaa 4. Higher means more blur. The default is 1.0. AUDIO OUTPUT OPTIONS (MPLAYER ONLY) -abs <value> (OBSOLETE) Override audio driver/card buffer size detection, -ao oss only -af <plugin1,plugin2,plugin3[=options],...> Activate a comma separated list of audio filters and their options. Available filters are: resample[=srate[:sloppy][:type]] Changes the sample rate of the audio stream to an inte- ger srate (Hz). It only supports the 16 bit little endian format. channels[=nch] Change the number of chan- nels to nch output channels. If the number of output channels is bigger than the number of input channels empty channels are inserted (except mixing from mono to stereo, then the mono chan- nel is repeated in both of the output channels). If the number of output chan- nels is smaller than the number of input channels the exceeding channels are trun- cated. format[=bps,f] Select the format f and bits per sample bps used for out- put from the filter layer. The option bps is an integer and denotes bytes per sam- ple. The format f is a string containing a concate- nated mix of: alaw, mulaw or imaadpcm float or int unsigned or signed le or be (little or big en- dian) volume[=v:sc] Select the output volume level. This filter is not reentrant and can therefore only be enabled once for ev- ery audio stream. v: desired gain in dB for all channels in the stream. The gain can be set from -200dB to +40dB (where -200dB mutes the sound completely and +40dB equals a gain of 1000). sc: enable soft clipping. pan[=n:l01:l02:..l10:l11:l12:...ln0:ln1:ln2:...] Mixes channels arbitrarily, see DOCS/sound.html for de- tails. n: number of output chan- nels (1 - 6). lij: how much of input channel j is mixed into output channel i. sub[=fc:ch] Add sub-woofer channel. fc: Cutoff frequency for low-pass filter (20Hz to 300Hz) default is 60Hz. ch: channel number for the sub-channel. surround[=d] Decoder for matrix encoded surround sound, works on many 2 channel files. d: delay time in ms for the rear speakers (0ms to 1000ms) default is 15ms. delay[=ch1:ch2:...] Delays the sound output. Specify the delay separately for each channel in mil- liseconds (floating point number between 0 and 1000). -af-adv <force=(0-3):list=(filters)> (see -af option too) Specify advanced audio filter options: force=<0-3> Forces the insertion of au- dio filters to one of the following: 0: Completely automatic insertion of filters (de- fault) 1: Optimize for speed 2: Optimize for accuracy 3: Turn off auto list=<filters> Same as -af (see -af op- tion). -ao <driver1[:device],driver2,...[,]> Specify a priority list of audio output drivers (optionally with device) to be used. 'device' is valid with SDL, too, it means subdriver then. NOTE: To get a full list of available drivers, see -ao help. If the list has a trailing ',' it will fallback to drivers not listed. EXAMPLE -ao oss:/dev/dsp2,oss:/dev/dsp1, try to use OSS with the specified sound devices and fallback to others if it fails -ao sdl:esd specify the SDL subdriver -aofile <filename> Filename for -ao pcm. -aop <list=plugin1,plugin2...:option1=value1:opt2=val2...> Specify audio plugin(s) and their options (see doc- umentation too). Available options are: list=[plugins] comma separated list of plu- gins (resample, surround, format, volume, extrastereo, volnorm) delay=<sec> example plugin, do not use. format=<format> output format (format plugin only) fout=<Hz> output frequency (resample plugin only) volume=<0-255> volume (volume plugin only) mul=<value> stereo coefficient (default: 2.5) (extrastereo plugin on- ly) softclip compressor / 'soft-clipping' capabilities (volume plugin only) -delay <sec> Audio delay in seconds (may be +/- float value). -format <0-8192> Select the format used for output from the filter layer (according to the defines in libao2/afmt.h): 1 Mu-Law 2 A-Law 4 Ima-ADPCM 8 Signed 8-bit 16 Unsigned 8-bit 32 Unsigned 16-bit (Little-En- dian) 64 Unsigned 16-bit (Big-Endian) 128 Signed 16-bit (Little-Endi- an) 256 Signed 16-bit (Big-Endian) 512 MPEG (2) Audio 1024 AC3 4096 Signed 32-bit (Little-Endi- an) 8192 Signed 32-bit (Big-Endian) -mixer <device> This option will tell MPlayer to use a different device for mixing than /dev/mixer. -nowaveheader (-ao pcm only) Don't include wave header. Used for RAW PCM. VIDEO OUTPUT OPTIONS (MPLAYER ONLY) -aa* (-vo aa only) You can get a list and an explanation of available options executing mplayer -aahelp -bpp <depth> Use different color depth than autodetect. Not all -vo drivers support it (fbdev, dga2, svga, vesa). -brightness <-100-100> Adjust brightness of video output (default 0). It changes intensity of RGB components of video signal from black to white screen. -contrast <-100-100> Adjust contrast of video output (default 0). Works in similar manner as brightness. -dfbopts <value> (-vo directfb2 only) Specify a parameter list for the directfb driver. -display <name> Specify the hostname and display number of the X server you want to display on. EXAMPLE: -display xtest.localdomain:0 -double Enables doublebuffering. Fixes flicker by storing two frames in memory, and displaying one while de- coding another. Can affect OSD. Needs twice the memory of a single buffer, so it won't work on cards with very little video memory. -dr Turns on direct rendering (not supported by all codecs and video outputs) (default is off). Warn- ing: may cause OSD/SUB corruption! -dxr2 <option1:option2:...> This option is used to control the dxr2 driver. Note: The lavc filter is now auto inserted if you try to play a non MPEG1/2 format so all formats supported by MPlayer should play out of the box (if you have the CPU power needed to encode on the fly). The overlay chipset used on the dxr2 is of pretty bad quality but the default settings should work for everybody. The OSD may be usable with the overlay (not on TV) by drawing it in the colorkey. With the default colorkey settings you may get variable results, usually you will see the colorkey around the characters or some other funny effect. But if you properly adjust the colorkey settings you should be able to get acceptable results. ar-mode=<value> aspect ratio mode (0 = nor- mal, 1 = pan scan, 2 = let- terbox (default)) iec958-encoded/decoded iec958 output mode mute mute sound output ucode=<value> path to the microcode TV Out 75ire enable 7.5 IRE bw b/w TV output color color TV output interlaced interlaced TV output macrovision=<value> macrovision mode (0 = off (default), 1 = agc, 2 = agc 2 colorstripe, 3 = agc 4 colorstripe) norm=<value> TV norm (ntsc (default), pal,pal60,palm,paln,palnc) square/ccir601-pixel TV pixel mode Overlay cr-[left|right|top|bot]=<-20-20> adjust the overlay cropping ck-[rgb]min=<0-255> minimum value for the color key ck-[rgb]max=<0-255> maximum value for the color key ck-[rgb]=<0-255> color key values ignore-cache do not use the VGA cache ol-osd enable the osd hack on the overlay ol[hwxy]-cor=<value> adjust the overlay size and position in case it doesn't match the window perfectly overlay enable the overlay overlay-ratio=<1-2500> tune the overlay (default 1000) update-cache recreate the VGA cache -fb <device> (fbdev or DirectFB only) Specifies the framebuffer device to use. By de- fault it uses /dev/fb0. -fbmode <modename> (fbdev only) Change video mode to the one that is labelled as <modename> in /etc/fb.modes. NOTE: VESA framebuffer doesn't support mode changing. -fbmodeconfig <filename> (fbdev only) Use this configuration file instead of the default /etc/fb.modes. Only valid for the fbdev driver. -forcexv (SDL only) Force using XVideo. -fs Fullscreen playing (centers movie, and makes black bands around it). Toggle it with the 'f' key (not all video outputs support it). See also -zoom. -fsmode-dontuse <0-31> (OBSOLETE) (use -fs option) Try this option if you still experience fullscreen problems. -fstype <type1,type2,...> Specify a priority list of fullscreen layer setting modes to be used. The default order is "lay- er,stays_on_top,above,fullscreen". It will be used as a fallback in case of specifying incorrect or unsupported modes. If you experience problems with fullscreen window being covered by other windows try using a differ- ent order. NOTE: See -fstype help for a full list of available modes. -geometry x[%][:y[%]] or [WxH][+x+y] Adjust where the output is on the screen initially. The x and y specifications are in pixels measured from the top-right of the screen to the top-right of the image being displayed, however if a percent- age sign is given after the argument it turns the value into a percentage of the screen size in that direction. It also supports the standard option format to the standard X -geometry option. The values given must be integers. Note: This option is only supported by a few vo's, including tdfxfb, fbdev and xv. EXAMPLE: 50:40 Places the window at x=50, y=40 50%:50% Places the window in the middle of the screen 100% Places the window at the top left corner of the screen 100%:100% Places the window at the bottom left corner of the screen -guiwid <window id> This tells the GUI to also use an X11 window and stick itself to the bottom of the video, which is useful to embed a mini-GUI in a browser (with the mplayerplug-in for instance). -hue <-100-100> Adjust hue of video signal (default: 0). You can get colored negative of image with this option. -icelayer <0-15> (icewm only) Sets the layer of the fullscreen window of mplayer for icewm. 0 Desktop 2 Below 4 Normal 6 OnTop 8 Dock 10 AboveDock 12 Menu (default) -jpeg <option1:option2:...> (-vo jpeg only) Specify options for the JPEG output. Available options are: [no]progressive Specify standard or progres- sive JPEG. [no]baseline Specify use of baseline or not. optimize=<value> Optimization factor [0-100] smooth=<value> Smooth factor [0-100] quality=<value> Quality factor [0-100] outdir=<value> Directory to save the JPEG files -monitor_dotclock <dotclock (or pixelclock) range> (fbdev and vesa only) Look into etc/example.conf for further information and in DOCS/video.html. -monitor_hfreq <horizontal frequency range> (fbdev and vesa only) -monitor_vfreq <vertical frequency range> (fbdev and vesa only) -monitoraspect <ratio> Set aspect ratio of your monitor or TV screen. See also -aspect for movie aspect. EXAMPLE: -monitoraspect 4:3 or 1.3333 -monitoraspect 16:9 or 1.7777 -nograbpointer Do not grab mouse pointer after VidMode change (-vm), useful for multihead setup. -nokeepaspect Do not keep window aspect ratio when resizing X11 windows (Works currently only with -vo x11, xv, xm- ga and xvidix and your window manager needs to un- derstand window aspect hints.). -noslices Disable drawing video by 16-pixel height slices/ bands, instead draws the whole frame in a single run. May be faster or slower, depending on card/ cache. It has effect only with libmpeg2 and libav- codec codecs. -panscan <0.0-1.0> Enables Pan & Scan functionality, i.e. in order to display a 16:9 movie on a 4:3 display, the sides of the movie are cropped to get a 4:3 image which fits the screen. This function works only with the xv, xmga, mga and xvidix video out drivers. The range controls how much of the image is cropped. -rootwin Play movie in the root window (desktop background) instead of opening a new one. Works only with x11, xv, xmga and xvidix drivers. -saturation <-100-100> Adjust saturation of video output (default: 0). You can get grayscale output with this option. -screenw <pixels> -screenh <pixels> If you use an output driver which can't know the resolution of the screen (fbdev/x11 and/or TVout) this is where you can specify the horizontal and vertical resolution. -stop_xscreensaver Turns off xscreensaver at startup and turns it on again on exit. -vm Try to change to a better video mode. dga, x11/xv (XF86VidMode) and sdl output drivers support it. -vo <driver1[:device],driver2,...[,]> Specify a priority list of video output drivers (optionally with device) to be used. 'device' is valid with SDL and GGI, too, it means subdriver then. NOTE: See -vo help for a full list of available drivers. If the list has a trailing ',' it will fallback to drivers not listed. EXAMPLE: -vo xmga,xv, Try Matrox kernel driver, then Xv driver, then others -vo sdl:aalib specify the SDL subdriver -vsync Enables VBI for vesa. -wid <window id> This tells MPlayer to use a X11 window, which is useful to embed MPlayer in a browser (with the plugger extension for instance). -xineramascreen <0-...> In Xinerama configurations (i.e. a single desktop that spans across multiple displays) this option tells MPlayer which screen to display movie on. -z <0-9> Specifies compression level for PNG output (-vo png) 0 no compression 9 max compression -zrbw (-vo zr only) Display in black and white (for optimal perfor- mance, this option can be combined with the 'decode only in black and white' option for codecs belong- ing to the FFmpeg family). -zrcrop <[width]x[height]+[x offset]+[y offset]> (-vo zr only) Select a part of the input image for display, mul- tiple occurences of this option switch on cinerama mode. In cinerama mode the movie is distributed over more than one TV (or beamer) to create a larg- er screen. Options appearing after the n-th -zr- crop apply to the n-th MJPEG card, each card should at least have a -zrdev in addition to the -zrcrop. For examples, see the output of -zrhelp and the Zr section of the documentation. -zrdev <device> (-vo zr only) Specify the device special file that belongs to your MJPEG card, by default this driver takes the first v4l device it can find. -zrfd (-vo zr only) Force decimation: Decimation, as specified by -zrhdec and -zrvdec, only happens if the hardware scaler can stretch the image to its original size. Use this option to force decimation. -zrhelp (-vo zr only) Display a list of all -zr* options, their default values and an example of cinerama mode. -zrnorm <norm> (-vo zr only) Specify norm PAL/NTSC, the default is 'no change'. -zrquality <1-20> (-vo zr only) A number from 1 to 20 representing the jpeg encod- ing quality. 1 gives the best quality and 20 gives very bad quality. -zrvdec <1,2,4> -zrhdec <1,2,4> (-vo zr only) Vertical/horizontal decimation: Ask the driver to send only every 2nd or 4th line/pixel of the input image to the MJPEG card and use the scaler of the MJPEG card to strech the image to its original size. -zrxdoff <x display offset>, -zrydoff <y display offset> (-vo zr only) If the movie is smaller than the TV screen, these options control the position of the movie relative to the upper left corner of the screen. The movie is centered by default. DECODING/FILTERING OPTIONS -ac <[-]codec1,[-]codec2,...[,]> Specify a priority list of audio codecs to be used, according to their codec name in codecs.conf. Use a '-' before the codec name to omit it. NOTE: See -ac help for a full list of available codecs. If the list has a trailing ',' it will fallback to codecs not listed. EXAMPLE: -ac mp3acm force l3codeca.acm MP3 codec -ac mad, try libmad first, then fall- back to others -ac hwac3,a52, try hardware AC3 passthrough, then software AC3 codec, then others -ac -ffmp3, try other codecs except FFm- peg's MP3 decoder -afm <driver1,driver2,...> Specify a priority list of audio drivers to be used, according to their driver name in codecs.conf. It falls back to default if none is ok. NOTE: See -afm help for a full list of available drivers. EXAMPLE: -afm ffmpeg try FFmpeg's libavcodec (mp1/2/3) codecs first -afm acm,dshow try Win32 codecs first -aspect <ratio> Override aspect ratio of movies. It's autodetected on MPEG files, but can't be autodetected on most AVI files. EXAMPLE: -aspect 4:3 or -aspect 1.3333 -aspect 16:9 or -aspect 1.7777 -flip Flip image upside-down. -lavdopts <option1:option2:...> (DEBUG CODE) If decoding with libavcodec, you can specify its parameters here. EXAMPLE: -lavdopts bug=1 NOTE: Just add the values of the things you want to en- able. Available options are: ec error concealment: 1: use strong deblock filter for damaged MBs 2: iterative MV search (slow) 3: all (default) er=<value> error resilience: 0: disabled 1: careful (should work with broken encoders) 2: normal (default) (works with compliant en- coders) 3: agressive (more checks but might cause problems even for valid bit- streams) 4: very agressive bug=<value> manually work around encoder bugs: 0: nothing 1: autodetect bugs (de- fault) 2 (msmpeg4v3): some old lavc generated msmpeg4v3 files (no autodetect) 4 (mpeg4): xvid interlac- ing bug (autodetected if fourcc==XVIX) 8 (mpeg4): UMP4 (autode- tected if fourcc==UMP4) 16 (mpeg4): padding bug 32 (mpeg4): illegal vlc bug (autodetected per fourcc) 64 (mpeg4): XVID and DIVX qpel bug (autodetected) idct=<0-99> (see lavcopts) gray grayscale only decoding (a bit faster than with color) -noaspect Disable automatic movie aspect ratio compensation. -nosound Do not play/encode sound. -pp <quality> (see -vop pp option too!) Set postprocess level of the DLL. This option is NO LONGER USABLE with MPlayer's postprocess filter, but only with Win32 DirectShow DLLs which have in- ternal postprocessing routine. The valid range of -pp value vary on codecs, mostly 0-6, where 0=disable 6=slowest/best. -pphelp (see -vop pp option too) Show a summary about the available postprocess fil- ters and their usage. -ssf <mode> Specifies SwScaler parameters. EXAMPLE -vop scale -ssf lgb=3.0 lgb=<0-100> Gaussian blur filter (luma) cgb=<0-100> Gaussian blur filter (chro- ma) ls=<0-100> sharpen filter (luma) cs=<0-100> sharpen filter (chroma) chs=<h> chroma horizontal shifting cvs=<v> chroma vertical shifting -stereo <mode> Select type of MP2/MP3 stereo output. 0 Stereo 1 Left channel 2 Right channel -sws <software scaler type> (see -vop scale option too) This option sets the quality (and speed, respec- tively) of the software scaler, with the -zoom op- tion. For example with x11 or other outputs which lack hardware acceleration. Possible settings are: NOTE: For -sws 2 and 7, the sharpness can be set with the scaling parameter (p) of -vop scale (0 (soft) - 100 (sharp)), for -sws 9, it specifies the filter length (1 - 10). 0 fast bilinear (default) 1 bilinear 2 bicubic (good quality) 3 experimental 4 nearest neighbour (bad qual- ity) 5 area 6 luma bicubic / chroma bilin- ear 7 gauss 8 sincR 9 lanczos 10 bicubic spline -vc <[-]codec1,[-]codec2,...[,]> Specify a priority list of video codecs to be used, according to their codec name in codecs.conf. Use a '-' before the codec name to omit it. NOTE: See -vc help for a full list of available codecs. If the list has a trailing ',' it will fallback to codecs not listed. EXAMPLE: -vc divx force Win32/VFW DivX codec, no fallback -vc divx4, try divx4linux codec first, then fallback to others -vc -divxds,-divx, try other codecs except Win32 DivX codecs -vc ffmpeg12,mpeg12, try libavcodec's MPEG1/2 codec, then libmpeg2, then others -vfm <driver1,driver2,...> Specify a priority list of video drivers to be used, according to their driver name in codecs.conf. It falls back to default if none is ok. NOTE: If libdivxdecore support was compiled in, then odi- vx and divx4 now contains just the same DivX4 codec, but different APIs to reach it. For differ- ence between them and when to use which, check the DivX4 section in the documentation. See -vfm help for a full list of available drivers. EXAMPLE: -vfm ffmpeg,dshow,vfw try the libavcodec, then Di- rectshow, then VFW codecs and fallback to the others, if still none is ok -vfm xanim try XAnim codecs first -vop <...,filter3[=options],filter2,filter1> Activate a comma separated list of video filters and their options in reverse order. NOTE: The parameters are optional and if omitted, some of them are set to default values. Use '-1' to keep the default value. Parameters w:h means width x height in pixels, x:y means x;y position counted from the upper left corner of the bigger image. To get a full list of available plugins, see -vop help. Available filters are: crop[=w:h:x:y] Crops the given part of the image and discards the rest. Useful to remove black bands from widescreen movies. w,h: Cropped width and height, defaults to orig- inal width and height. x,y: Position of the cropped picture, defaults to center. cropdetect[=0-255] Calculates necessary crop- ping parameters and prints the recommended parameters to stdout. The threshold can be optionally specified from nothing (0) to every- thing (255). (default: 24) rectangle[=w:h:x:y] Draws a rectangle of the re- quested width and height at the specified coordinates over the image (useful for testing crop parameters). w,h: width and height (default: -1, maximum possible width where boundaries are still vis- ible. x,y: top left corner po- sition (default: -1, up- permost leftmost) The plugin responds to the input.conf directive 'change_rectangle' that takes two parameters. The first parameter can be 0 for w, 1 for h, 2 for x or 3 for y. The second parameter is the amount of pixels by which to change the desig- nated rectangle boundary. expand[=w:h:x:y:o] Expands (not scales) movie resolution to the given val- ue and places the unscaled original at coordinates x, y. Can be used for placing subtitles/OSD in the result- ing black bands. w,h: expanded width,height (default: original width,height) x,y: position of original image on the expanded im- age (default: center) o: OSD/subtitle render- ing 0: disable (default) 1: enable Negative values for w and h are treated as offsets to the original size, e.g. ex- pand=0:-50:0:0 adds a 50 pixel border to the bottom of the picture. flip Flips the image upside down. See also option -flip. mirror Mirrors the image on the Y axis. rotate[=<0-7>] Rotates and flips (optional) the image +/- 90 degrees. For parameters between 4-7 rotation is only done if the movie's geometry is portrait and not landscape. scale[=w:h[:c[:p]]] Scales the image with the software scaler (slow) and performs a YUV<->RGB col- orspace conversion (also see -sws option). w,h: new width/height af- ter scaling (default: original width,height) Note: If -zoom is used, and underlying fil- ters (including libvo) are incapable of scaling, then it defaults to d_width/d_height! -1: original width/ height 0: scaled d_width/ d_height -2: Calculate w/h us- ing the other dimension and the prescaled aspect ratio. -3: Calculate w/h us- ing the other dimension and the original aspect ratio. c: chroma skipping 0: use all available input lines for chroma 1: use only every 2. input line for chroma 2: use only every 4. input line for chroma 3: use only every 8. input line for chroma p: scaling parameter (depends upon the scaling method used) for -sws 2 (bicubic) it is sharpness (0 (soft) - 100 (sharp)) for -sws 7 (gaussian) it is sharpness (0 (soft) - 100 (sharp)) for -sws 9 (lanczos) it is filter length (1 - 10) The value 0 is used for scaled (aspect) des- tination w/h. (default: original w/h, destination w/h with -zoom) Optional- ly chroma skipping (c from 0-3) and scaling pa- rameters can be speci- fied. (see the -sws op- tion for details) yuy2 Forces software YV12/I420 or 422P to YUY2 conversion. Useful for video cards/ drivers with slow YV12 but fast YUY2 support. yvu9 Forces software YVU9 to YV12 colorspace conversion. Dep- recated in favor of the software scaler. rgb2bgr[=swap] RGB 24/32 <-> BGR 24/32 col- orspace conversion. swap: Also perform R <-> B swapping. palette RGB/BGR 8 -> 15/16/24/32bpp colorspace conversion using palette. format[=fourcc] Restricts the colorspace for the next filter without do- ing any conversion. Use to- gether with the scale filter for a real conversion. fourcc: format name like rgb15, bgr24, yv12, etc (default: yuy2) pp[=filter1[:option1[:option2...]]/[-]fil- ter2...] This option enables usage of MPlayer's internal postpro- cessing filter, and also gives an interface where you can pass options to the named filter. To get a list of available filters, use -pphelp. Note that each sub-filter must be separated with a / sign. Each filter defaults to 'c' (chrominance). The keywords accept a '-' prefix to disable the op- tion. A ':' followed by a letter may be appended to the op- tion to indicate its scope: a: Automatically switches the filter off if the CPU is too slow. c: Do chrominance filter- ing, too. y: Do not do chrominance filtering (only luminance filtering). EXAMPLES: -vop pp=hb/vb/dr/al/lb -vop pp=hb/vb/dr/al Default filters without brightness/contrast cor- rection: -vop pp=de/-al Enable default filters & temporal denoiser: -vop pp=de/tn:1:2:3 Deblock horizontal only luminance and switch ver- tical deblocking on or off automatically depend- ing on available CPU time: -vop pp=hb:y/vb:a -autoq 6 test Generate various test pat- terns. lavc[=quality:fps] Fast software YV12 to MPEG1 conversion with libavcodec for use with DVB/DXR3. Faster and of better quality than -vop fame. quality: 1 - 31 fixed qscale 32 - fixed bitrate in kBits fps: force output fps (float value) (default: 0, autodetect based on height) fame Fast software YV12 to MPEG1 conversion with libfame for use with DVB/DXR3. dvbscale[=aspect] Set up optimal scaling for DVB cards, scaling the X ax- is in hardware and calculat- ing the Y axis scaling in software to keep aspect. aspect: control aspect ratio, calculate as DVB_HEIGHT*ASPECTRATIO (default: 576*4/3=768), set it to 576*(16/9)=1024 for a 16:9 TV. Only useful together with expand+scale: -vop lavc,ex- pand=-1:576:-1:-1:1,scale=-1:0,dvb- scale noise[=luma[u][t|a][h][p]:chroma[u][t|a][h][p]] Adds noise. <0-100>: luma noise <0-100>: chroma noise u: uniform noise (gaus- sian otherwise) t: temporal noise (noise pattern changes between frames) a: averaged temporal noise (smoother, but a lot slower) h: high quality (slightly better looking, slightly slower) p: mix random noise with a (semi)regular pattern denoise3d[=luma:chroma:time] This filter aims to reduce image noise producing smooth images and making still im- ages really still (This should enhance compressibil- ity.). It can be given from 0 to 3 parameters. If you omit a parameter, a reason- able value will be inferred. luma: spatial luma strength (default = 4) chroma: spatial chroma strength (default = 3) time: temporal strength (default = 6) hqdn3d[=luma:chroma:time] High precision/quality ver- sion of the denoise3d fil- ter. Parameters and usage are the same. eq[=bright:cont] Software equalizer with in- teractive controls just like the hardware equalizer, for cards/drivers that do not support brightness and con- trast controls in hardware. Might also be useful with MEncoder, either for fixing poorly captured movies, or for slightly reducing con- trast to mask artifacts and get by with lower bitrates. Initial values in the range -100 - 100 may be given on the command line. eq2[=gamma:contrast:brightness:satura- tion:rg:gg:bg] Alternative software equal- izer that uses lookup tables (very slow), allowing gamma correction in addition to simple brightness, contrast and saturation adjustment. Note that it uses the same MMX optimized code as -vop eq if all gamma values are 1.0. The parameters are given as floating point val- ues. Parameters rg, gg, bg are the independent gamma values for the Red, Green and Blue components. De- faults are 1.0, bright- ness=0.0. Value ranges are 0.1-10 for gammas, -2-2 for contrast (negative values result in a negative image), -1-1 for brightness and 0-3 for saturation. halfpack[=f] Convert planar YUV 4:2:0 to half-height packed 4:2:2, downsampling luma but keep- ing all chroma samples. Useful for output to low- resolution display devices when hardware downscaling is poor quality or is not available. Can also be used as a primitive luma-only deinterlacer with very low cpu usage. By default, halfpack averages pairs of lines when downsampling. The optional parameter f can be 0 to only use even lines, or 1 to only use odd lines. Any other value for f gives the default (averaging) be- havior. dint[=sense:level] Detects and drops first of interlaced frames in video stream. Values can be from 0.0 to 1.0 - first (default 0.1) is relative difference between neighbor pixels, second (default 0.15) is what part of image have to be detected as interlaced to drop the frame. lavcdeint Use libavcodec's deinterlace filter. unsharp=l|cWxH:amount[:l|cWxH:amount] Unsharp mask / gaussian blur. l: Apply effect on luma component. c: Apply effect on chroma components. WxH: width and height of the matrix, odd sized in both directions (min = 3x3, max = 13x11 or 11x13, usually something between 3x3 and 7x7) amount: Relative amount of sharpness/blur to add to the image (a sane range should be -1.5 - 1.5). <0: blur >0: sharpen swapuv Swap U & V plane. il=[d|i][s][:[d|i][s]] (de)interleaves lines. The goal of this filter is to add the ability to process interlaced images pre-field without deinterlacing them. You can filter your inter- laced DVD and play it on a TV without breaking the in- terlacing. While deinter- lacing (with the postpro- cessing filter) removes in- terlacing permanently (by smoothing, averaging, etc) deinterleaving splits the frame into 2 fields (so called half pictures), so you can process (filter) them independently and then re-interleave them. d: deinterleave i: interleave s: swap fields (exchange even & odd lines) field[=n] Extracts a single field from an interlaced image using stride arithmetic to avoid wasting CPU time. The op- tional argument n specifies whether to extract the even or the odd field (depending on whether n is even or odd). detc[=var1=value2:var2=value2:...] Attempts to reverse the "telecine" process to recov- er a clean, non-interlaced stream at film framerate. This filter is still experi- mental but seems to be us- able. The following argu- ments (see syntax above) may be used to control its be- havior: dr: Set the frame drop- ping mode. 0 (default) means don't drop frames to maintain fixed output framerate. 1 means always drop a frame when there have been no drops or telecine merges in the past 5 frames. 2 means always maintain exact 5:4 input to output frame ra- tio. (Note: use mode 1 with MEncoder!) am: Analysis mode. Avail- able values are 0 (fixed pattern with initial frame number specified by fr=#) and 1 (agressive search for telecine pat- tern). Default is 1. fr: Set initial frame number in sequence. 0-2 are the three clean pro- gressive frames; 3 and 4 are the two interlaced frames. The default, -1, means "not in telecine sequence". The number specified here is the type for the imaginary previous frame before the movie starts. tr0, tr1, tr2, tr3: Threshold values to be used in certain modes. telecine[=start] Apply 3:2 "telecine" process to increase framerate by 20%. This most likely will not work correctly with mplayer, but it can be used with 'mencoder -fps 29.97 -ofps 29.97 -vop telecine'. Both fps options are essen- tial! (A/V sync will break if they are wrong.) The op- tional start parameter tells the filter where in the telecine pattern to start (0-3). tfields[=mode] Temporal field separation -- split fields into frames, doubling the output framer- ate. In mode 0, the filter will leave the fields un- changed, resulting in half- height output. In mode 1, interlaced parts of the im- age will be interpolated to reconstruct full-height frames. Like the telecine filter, "tfields" will only work properly with mencoder, and only if both -fps and -ofps are set to the desired (double) framerate! boxblur=radius:power[:radius:power] box blur radius: size of the fil- ter power: How often the fil- ter should be applied. sab=rad:pf:colorDiff[:rad:pf:colorDiff] shape adaptive blur rad: blur filter strength (~0.1-4.0) (slower if larger) pf: prefilter strength (~0.1-2.0) colorDiff: How different the pixels are allowed to be considered.

Ex- tracts both stereo fields and places them side by side, resizing them to main- tain the original movie as- pect. lines: number of lines to select from the middle of the image (default: 12) bmovl=hidden:opaque:<fifo> Read bitmaps from a FIFO and display them in a window. hidden: sets the default value of the 'hidden' flag (boolean) opaque: flag switching between alphablended (transparent) and opaque (fast) mode fifo: path/filename for the FIFO (named pipe con- necting mplayer -vop bmovl to the controlling application) FIFO commands are: RGBA32 width height xpos ypos alpha clear followed by width*height*4 bytes of raw RGBA32 data. ABGR32 width height xpos ypos alpha clear followed by width*height*4 bytes of raw ABGR32 data. RGB24 width height xpos ypos alpha clear followed by width*height*3 bytes of raw RGB32 data. BGR24 width height xpos ypos alpha clear followed by width*height*3 bytes of raw BGR32 data. ALPHA width height xpos ypos alpha change alpha for area CLEAR width height xpos ypos clear area OPAQUE disable all alpha trans- parency. Send "ALPHA 0 0 0 0 0" to enable it again. HIDE hide bitmap SHOW show bitmap Arguments are: width, height: size of image/area xpos, ypos: start blit- ting at X/Y position alpha: set alpha differ- ence. 0 means same as original, 255 makes ev- erything opaque, -255 makes everything trans- parent. If you set this to -255 you can then send a sequence of ALPHA-com- mands to set the area to -225, -200, -175 etc for a nice fade-in-effect! ;) clear: clear the frame- buffer before blitting. 1 means clear, if 0, the image will just be blit- ted on top of the old one, so you don't need to send 1,8MB of RGBA32 data everytime a small part of the screen is updated. -x <x> (MPLAYER only) Scale image to x width (if sw/hw scaling avail- able). Disables aspect calculations. -xvidopts <option1:option2:...> Specify additional parameters when decoding with XviD. dr2 Activate direct rendering method 2. nodr2 Deactivate direct rendering method 2. -xy <x> x<=8 Scale image by factor <x>. x>8 Set width to <x> and calcu- late height to keep correct aspect ratio. -y <y> (MPLAYER only) Scale image to y height (if sw/hw scaling avail- able). Disables aspect calculations. -zoom Allow software scaling, where available. Could be used to force scaling with -vop scale. NOTE: -vop scale will IGNORE options -x / -y / -xy / -fs / -aspect without -zoom. ENCODING OPTIONS (MENCODER ONLY) -audio-density <1-50> Number of audio chunks per second (default is 2 for 0.5s long audio chunks). NOTE: CBR only, VBR ignores this as it puts each packet in a new chunk. -audio-delay <0.0-...> Sets the audio delay field in the header. Default is 0.0, negative values do not work. This does not delay the audio while encoding, but the player will see the default audio delay, sparing you the use of the -delay option. -audio-preload <0.0-2.0> Sets up audio buffering time interval (default: 0.5s). -divx4opts <option1:option2:...> If encoding to DivX4, you can specify its parame- ters here. Available options are: help get help br=<value> specify bitrate in kbit <4-16000> or bit <16001-24000000> key=<value> maximum keyframe interval (in frames) deinterlace enable deinterlacing (avoid it, DivX4 is buggy) q=<1-5> quality (1-fastest, 5-best) min_quant=<1-31> minimum quantizer max_quant=<1-31> maximum quantizer rc_period=<value> rate control period rc_reaction_period=<value> rate control reaction period rc_reaction_ratio=<value> rate control reaction ratio crispness=<0-100> specify crispness/smoothness pass=<1-2> With this you can encode 2pass DivX4 files. First encode with pass=1, then with the same parameters, encode with pass=2. vbrpass=<0-2> Override the pass argument and use XviD VBR Library in- stead of DivX4 VBR. Avail- able options are: 0: one pass encoding (as in not putting pass on the command line) 1: Analysis (first) pass of two pass encoding. The resulting AVI file can be directed to /dev/null. 2: Final (second) pass of two pass encoding. -endpos <[[hh:]mm:]ss[.ms]|size[b|kb|mb]> (see -ss and -sb option too) Stop encoding at given time or byte position. Can be specified in many ways: NOTE: Byte position won't be accurate, as it can only stop at a frame boundary. EXAMPLE: -endpos 56 encode only 56 seconds -endpos 01:10:00 encode only 1 hour 10 min- utes -endpos 100mb encode only 100 MBytes -ffourcc <fourcc> Can be used to override the video fourcc of the output file. EXAMPLE: -ffourcc div3 will have the output file contain 'div3' as video fourcc. -include <configuration file> Specify configuration file to be parsed after the default ones. -info <option1:option2:...> (.AVI only) Specify the info header of the resulting .AVI file. Available options are: help show this description name=<value> title of the subject of the file artist=<value> artist or author of the original subject of the file genre=<value> original work category subject=<value> contents of the file copyright=<value> copyright information for the file srcform=<value> original form of the materi- al that was digitized comment=<value> general comments about the file or the subject of the file -lameopts <option1:option2:...> If encoding to MP3 with libmp3lame, you can specify its parameters here. Available options are: help get help vbr=<0-4> variable bitrate method 0: cbr 1: mt 2: rh (default) 3: abr 4: mtrh abr average bitrate cbr constant bitrate. Forces also CBR mode encod- ing on subsequent ABR pre- sets modes br=<0-1024> specify bitrate in kBit (CBR and ABR only) q=<0-9> quality (0-highest, 9-low- est) (only for VBR) aq=<0-9> algorithmic quality (0-best/ slowest, 9-worst/fastest) ratio=<1-100> compression ratio vol=<0-10> set audio input gain mode=<0-3> (default: auto) 0: stereo 1: joint-stereo 2: dualchannel 3: mono padding=<0-2> 0: no 1: all 2: adjust fast switch on faster encoding on subsequent VBR presets modes, slightly lower quali- ty and higher bitrates. preset=<value> provide the highest possible quality settings. medium: VBR encoding, good quality, 150-180 kbps bitrate range. standard: VBR encoding, high quality, 170-210 kbps bitrate range. extreme: VBR encoding, very high quality, 200-240 kbps bitrate range. insane: CBR encoding, highest preset quality, 320 kbps bitrate. <8-320>: ABR encoding at average given kbps bi- trate. EXAMPLE: -lameopts fast:preset=standard for most people on most mu- sic and already quite high in quality. -lameopts cbr:preset=192 encode with ABR presets at a 192 kbps forced constant bi- trate. -lameopts preset=172 encode with ABR presets at a 172 kbps average bitrate. -lameopts preset=extreme for people with extremely good hearing and similar equipment. -lameopts preset=help print additional options and informations on presets set- tings. -lavcopts <option1:option2:...> If encoding with libavcodec, you can specify its parameters here. EXAMPLE: -lavcopts vcodec=msmpeg4:vbi- trate=1800:vhq:keyint=250 Available options are: vcodec=<value> use the specified codec (there is no default, you must specify it): mjpeg: Motion JPEG h263: H263 h263p: H263 Plus mpeg4: DivX 4/5 msmpeg4: DivX 3 rv10: an old RealVideo codec mpeg1video: MPEG1 video :) vqmin=<1-31> minimum quantizer (pass 1/2) 1: Not recommended (much larger file, little qual- ity difference and weird side effects: msmpeg4, h263 will be very low quality, ratecontrol will be confused resulting in lower quality and some decoders will not be able to decode it). 2: Recommended for normal mpeg4/mpeg1video encoding (default). 3: Recommended for h263(p)/msmpeg4. The rea- son for preferring 3 over 2 is that 2 could lead to overflows (this will be fixed for h263(p) by changing the quantizer per MB in the future, msmpeg4 cannot be fixed as it does not support that) vqscale=<1-31> Constant quantizer / con- stant quality encoding (se- lects fixed quantizer mode). A lower value means better quality but larger files (default: 0 (disabled)). 1 is not recommended (see -vqmin for details). vqmax=<1-31> maximum quantizer (pass 1/2) 10-31 should be a sane range (default: 31) mbqmin=<1-31> minimum macroblock quantizer (pass 1/2) (default: 2) mbqmax=<1-31> maximum macroblock quantizer (pass 1/2) (default: 31) vqdiff=<1-31> maximum quantizer difference between I or P frames (pass 1/2) (default: 3) vmax_b_frames=<0-4> maximum number of B frames between non B frames: 0: no B frames (default) 0-2: sane range for MPEG4 vme=<0-5> motion estimation method: 0: none (very low quali- ty) 1: full (slow) 2: log (low quality) 3: phods (low quality) 4: EPZS (default) 5: X1 (experimental) Note: 0-3 currently ig- nores the amount of Bits spent, so quality may be low. vhq high quality mode, encode each macro block in all modes and choose the best. This is slow but results in better quality and file size. (default: disabled) v4mv Allow 4 motion vectors per macroblock (slightly better quality). (default: dis- abled) keyint=<0-300> maximum interval between keyframes in frames. Keyframes are needed for seeking as seeking is only possible to a keyframe but keyframes need more space than other frames so larger numbers here mean slightly smaller files, but less pre- cise seeking, 0 means no key frames. Values >300 are not recommended as the quality might be bad depending upon decoder, encoder and luck. For a strict MPEG1/2/4 com- pliance this would have to be <=132. (default: 250 or one key frame every ten sec- onds in a 25fps movie) vb_strategy=<0-1> strategy to choose between I/P/B frames (pass 2): 0: always use the maximum number of B frames (de- fault) 1: avoid B frames in high motion scenes (will cause bitrate misprediction) vpass=<1-2> Activates internal two pass mode, only specify if you wish to use two pass encod- ing (default: disabled). 1: first pass 2: second pass Tip: Try to use constant quantizer mode for pass one (vqscale=<quantizer>). huffyuv: pass 1 saves statistics pass 2 encodes with an optimal Huffman table based upon pass 1 statis- tics. aspect=<x/y> Store movie aspect internal- ly, just like MPEG files. Much nicer solution than rescaling, because quality isn't decreased. Only MPlayer will play these files correctly, other play- ers will display them with wrong aspect. The aspect parameter can be given as a ratio or a floating point number. Example: aspect=16/9, aspect=1.78 vbitrate=<value> specify bitrate (pass 1/2) in kBit <4-16000> or Bit <16001-24000000> (warning: 1kBit = 1000 Bits) (default: 800) vratetol=<value> approximated filesize toler- ance in kBit. 1000-100000 is a sane range. (warning: 1kBit = 1000 Bits) (default: 8000) vrc_maxrate=<value> maximum bitrate in kbit/sec (pass 1/2) vrc_minrate=<value> minimum bitrate in kbit/sec (pass 1/2) vrc_buf_size=<value> buffer size in kbit (pass 1/ 2). Note: vratetol should not be too large during the second pass or there might be problems if vrc_(min|max)rate is used. vb_qfactor=<-31.0-31.0> quantizer factor between B and non B frames (pass 1/2) (default: 1.25) vi_qfactor=<-31.0-31.0> (pass 1/2) (default: 0.8) vb_qoffset=<-31.0-31.0> quantizer offset between B and non B frames (pass 1/2) (default: 1.25) vi_qoffset=<-31.0-31.0> (pass 1/2) (default: 0.0) if v{b|i}_qfactor > 0 I/B-Frame quantizer = P- Frame quantizer * v{b|i}_qfactor + v{b|i}_qoffset else do normal ratecontrol (dont lock to next P frame quan- tizer) and set q= -q * v{b|i}_qfactor + v{b|i}_qoffset Tip: To do constant quantiz- er encoding with different quantizers for I/P and B frames you can use: vqmin=<ip_quant>:vq- max=<ip_quant>:vb_qfac- tor=<b_quant/ip_quant> vqblur=<0.0-1.0> quantizer blur (pass1) Larg- er values will average the quantizer more over time (slower change). 0.0: qblur disabled 0.5 (default) 1.0: average the quantiz- er over all previous frames vqblur=<0.0-99.0> quantizer gaussian blur (pass2) Larger values will average the quantizer more over time (slower change) (default: 0.5) vqcomp=<value> quantizer compression, de- pends upon vrc_eq (pass 1/2) (default: 0.5) vrc_eq=<equation> main ratecontrol equation (pass 1/2): 1: constant bitrate tex: constant quality 1+(tex/avgTex-1)*qComp: ap- proximately the equation of the old ratecontrol code tex^qComp: with qcomp 0.5 or something like that (de- fault) infix operators: +,-,*,/,^ variables: tex: texture complexity iTex,pTex: intra, non intra texture complexity avgTex: average texture complexity avgIITex: average in- tra texture complexity in I frames avgPITex: average in- tra texture complexity in P frames avgPPTex: average non intra texture complexity in P frames avgBPTex: average non intra texture complexity in B frames mv: Bits used for motion vectors fCode: maximum length of motion vector in log2 scale iCount: number of intra macro blocks / number of macro blocks var: spatial complexity mcVar: temporal complexity qComp: qcomp from the command line isI, isP, isB: is 1 if picture type is I/P/B else 0 Pi,E: see your favorite math book functions: max(a,b),min(a,b): maximum / minimum gt(a,b): is 1 if a>b, 0 oth- erwise lt(a,b): is 1 if a<b, 0 oth- erwise eq(a,b): is 1 if a==b,0 oth- erwise sin, cos, tan, sinh, cosh, tanh, exp, log, abs vrc_override=<options> User specified quality for specific parts (ending, credits, ..)

Adds 2 Bytes per video packet, im- proves error-resistance when transferring over unreliable channels (eg. streaming over the internet) Each video packet will be encoded in 3 separate partitions: 1. MVs (=movement) 2. DC coefficients (=low res picture) 3. AC coefficients (=de- tails) MV & DC are most important, loosing them looks far worse than loosing the AC and the 1. & 2. partition. (MV&DC) are far smaller than the 3. partition (AC) meaning that errors will hit the AC par- tition much more often than the MV&DC partitions. Thus, the picture will look better with partitioning than with- out, as without partitioning an error will trash AC/DC/MV equally. vpsize=<0-10000> video packet size, improves error-resistance (see -vd- part option too): 0: disabled (default) 100-1000: good choice gray grayscale only encoding (faster) (default: disabled) vfdct=<0-10> dct algorithm: 0: automatically select a good one (default) 1: fast integer 2: accurate integer 3: mmx 4: mlib idct=<0-99> idct algorithm.

This will find the optimal encod- ing for each 8x8 block. Trellis quantization is quite simple a optimal quan- tization in the PSNR vs bi- trate sense (assuming that there would be no rounding errors introduced by the ID- CT, which is obviously not the case) it simply finds a block for the minimum of er- ror and lambda*bits. lambda: qp dependant con- stant bits: amount of bits needed to encode the block error: sum of squared er- rors of the quantization last_pred=<0-99> Amount of motion predictors from the previous frame 0: (default) a: will use 2a+1 x 2a+1 macro block square of mo- tion vector predictors from the previous frame preme=<0-2> motion estimation pre-pass 0: disabled 1: only after I frames (default) 2: always subq=<1-8> subpel refinement quality (for qpel) (default: 8). Note: This has a significant effect on the speed. psnr print the psnr (peak signal to noise ratio) for the whole video after encoding and store the per frame psnr in a file with a name like 'psnr_012345.log'. Return values are in dB (decibel), the higher the better. mpeg_quant use MPEG quantizers instead of H.263. (default: dis- abled) (i.e. use H.263 quan- tizers) aic advanced intra prediction (H.263+ only) Note: vqmin should be 8 or larger. umv unlimited MVs (H.263+ only) Allow encoding of abritarily long MVs. -noskip Do not skip frames. -o <filename> Outputs to the given filename, instead of the de- fault 'test.avi'. -oac <codec name> Encode with the given audio codec. Use -ovc help to get a list of available codecs. (no default set) EXAMPLE: -oac copy no encoding, just streamcopy -oac pcm encode to uncompressed PCM -oac mp3lame encode to MP3 (using Lame) -of <format> (BETA CODE!) Encode to the specified format. Use -of help to get a list of available formats. EXAMPLE: -of avi encode to avi (default) -of mpeg encode to mpeg -ofps <fps> The output file will have different frame/sec than the source.
