General usage============= ::   mpv infile --o=outfile [--of=outfileformat] [--ofopts=formatoptions] [--orawts] \    [(any other mpv options)] \    --ovc=outvideocodec [--ovcopts=outvideocodecoptions] \    --oac=outaudiocodec [--oacopts=outaudiocodecoptions] Help for these options is provided if giving help as parameter, as in::   mpv --ovc=help The suboptions of these generally are identical to ffmpeg's (as option parsingis simply delegated to ffmpeg). The option --ocopyts enables copying timestampsfrom the source as-is, instead of fixing them to match audio playback time(note: this doesn't work with all output container formats); --orawts even turnsoff discontinuity fixing. Note that if neither --ofps nor --oautofps is specified, VFR encoding is assumedand the time base is 24000fps. --oautofps sets --ofps to a guessed fps numberfrom the input video. Note that not all codecs and not all formats support VFRencoding, and some which do have bugs when a target bitrate is specified - use--ofps or --oautofps to force CFR encoding in these cases. Of course, the options can be stored in a profile, like this .config/mpv/mpv.confsection::   [myencprofile]  vf-add = scale=480:-2  ovc = libx264  ovcopts-add = preset=medium  ovcopts-add = tune=fastdecode  ovcopts-add = crf=23  ovcopts-add = maxrate=1500k  ovcopts-add = bufsize=1000k  ovcopts-add = rc_init_occupancy=900k  ovcopts-add = refs=2  ovcopts-add = profile=baseline  oac = aac  oacopts-add = b=96k It's also possible to define default encoding options by putting them intothe section named ``[encoding]``. (This behavior changed after mpv 0.3.x. Inmpv 0.3.x, config options in the default section / no section were appliedto encoding. This is not the case anymore.) One can then encode using this profile using the command::   mpv infile --o=outfile.mp4 --profile=myencprofile Some example profiles are provided in a fileetc/encoding-profiles.conf; as for this, see below.  Encoding examples================= These are some examples of encoding targets this code has been used and testedfor. Typical MPEG-4 Part 2 ("ASP", "DivX") encoding, AVI container::   mpv infile --o=outfile.avi \    --vf=fps=25 \    --ovc=mpeg4 --ovcopts=qscale=4 \    --oac=libmp3lame --oacopts=b=128k Note: AVI does not support variable frame rate, so the fps filter must be used.The frame rate should ideally match the input (25 for PAL, 24000/1001 or30000/1001 for NTSC) Typical MPEG-4 Part 10 ("AVC", "H.264") encoding, Matroska (MKV) container::   mpv infile --o=outfile.mkv \    --ovc=libx264 --ovcopts=preset=medium,crf=23,profile=baseline \    --oac=libopus --oacopts=qscale=3 Typical MPEG-4 Part 10 ("AVC", "H.264") encoding, MPEG-4 (MP4) container::   mpv infile --o=outfile.mp4 \    --ovc=libx264 --ovcopts=preset=medium,crf=23,profile=baseline \    --oac=aac --oacopts=b=128k Typical VP8 encoding, WebM (restricted Matroska) container::   mpv infile -o outfile.mkv \    --of=webm \    --ovc=libvpx --ovcopts=qmin=6,b=1000000k \    --oac=libopus --oacopts=qscale=3  Device targets============== As the options for various devices can get complex, profiles can be used. An example profile file for encoding is provided inetc/encoding-profiles.conf in the source tree. This file is installed and loadedby default. If you want to modify it, you can replace and it with your own copyby doing::   mkdir -p ~/.mpv  cp /etc/mpv/encoding-profiles.conf ~/.mpv/encoding-profiles.conf Keep in mind that the default profile is the playback one. If you want to addoptions that apply only in encoding mode, put them into a ``[encoding]``section. Refer to the top of that file for more comments - in a nutshell, the followingoptions are added by it::   --profile=enc-to-dvdpal      # DVD-Video PAL, use dvdauthor -v pal+4:3 -a ac3+en  --profile=enc-to-dvdntsc     # DVD-Video NTSC, use dvdauthor -v ntsc+4:3 -a ac3+en  --profile=enc-to-bb-9000     # MP4 for Blackberry Bold 9000  --profile=enc-to-nok-6300    # 3GP for Nokia 6300  --profile=enc-to-psp         # MP4 for PlayStation Portable  --profile=enc-to-iphone      # MP4 for iPhone  --profile=enc-to-iphone-4    # MP4 for iPhone 4 (double res)  --profile=enc-to-iphone-5    # MP4 for iPhone 5 (even larger res) You can encode using these with a command line like::   mpv infile --o=outfile.mp4 --profile=enc-to-bb-9000 Of course, you are free to override options set by these profiles by specifyingthem after the -profile option.  What works========== * Encoding at variable frame rate (default)* Encoding at constant frame rate using --vf=fps=RATE* 2-pass encoding (specify flags=+pass1 in the first pass's --ovcopts, specify  flags=+pass2 in the second pass)* Hardcoding subtitles using vobsub, ass or srt subtitle rendering (just  configure mpv for the subtitles as usual)* Hardcoding any other mpv OSD (e.g. time codes, using --osdlevel=3 and  --vf=expand=::::1)* Encoding directly from a DVD, network stream, webcam, or any other source  mpv supports* Using x264 presets/tunings/profiles (by using profile=, tune=, preset= in the  --ovcopts)* Deinterlacing/Inverse Telecine with any of mpv's filters for that* Audio file converting: mpv --o=outfile.m4a infile.flac --no-video  --oac=aac --oacopts=b=320k What does not work yet====================== * 3-pass encoding (ensuring constant total size and bitrate constraints while  having VBR audio; mencoder calls this "frameno")* Direct stream copy
