+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 parsing
+is simply delegated to ffmpeg). The option --ocopyts enables copying timestamps
+from 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 turns
+off discontinuity fixing.
+
+Note that if neither --ofps nor --oautofps is specified, VFR encoding is assumed
+and the time base is 24000fps. --oautofps sets --ofps to a guessed fps number
+from the input video. Note that not all codecs and not all formats support VFR
+encoding, 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.conf
+section::
+
+  [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 into
+the section named ``[encoding]``. (This behavior changed after mpv 0.3.x. In
+mpv 0.3.x, config options in the default section / no section were applied
+to 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 file
+etc/encoding-profiles.conf; as for this, see below.
+
+
+Encoding examples
+=================
+
+These are some examples of encoding targets this code has been used and tested
+for.
+
+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 or
+30000/1001 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 in
+etc/encoding-profiles.conf in the source tree. This file is installed and loaded
+by default. If you want to modify it, you can replace and it with your own copy
+by 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 add
+options 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 following
+options 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 specifying
+them 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
