The code touched by this commit makes sure that DVD subtitle tracks known by libdvdread but not known by demux_lavf can be selected and displayed properly. These subtitle tracks have the first packet some time late in the packet stream, so that libavformat won't immediately recognize them, and will add the track as soon as the first packet is seen during normal demuxing. demux_mpg used to handle this elegantly: you just set the MPEG ID of the stream you wanted. demux_lavf couldn't do this, so it was emulated with a DEMUXER_CTRL. This commit changes it so that new streams are selected by default (if autoselect is enabled), and the playloop simply can take appropriate action before the lower layer throws away the first packet. This also changes the demux_lavf behavior that subtitle packets are always demuxed, even if not needed. (They were immediately thrown away, so there was no advantage to this.) Further, this adds the ability to demux.c to deal with demuxing more than one stream of a kind at once. (Though currently it's not useful.)
mpv
Overview
mpv is a movie player based on MPlayer and mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types.
If you are wondering what's different from mplayer2 and MPlayer you can read more about the changes.
Compilation
Compiling with full features requires development files for several
external libraries. Below is a list of some important requirements. For
more information see the output of ./configure --help for a list of options,
or look at the list of enabled and disabled features printed after running
./configure. If you think you have support for some feature installed
but configure fails to detect it, the file config.log may contain
information about the reasons for the failure.
Essential dependencies (incomplete list):
- gcc or clang
- X development headers (xlib, X extensions, libvdpau, libGL, libXv, ...)
- Audio output development headers (libasound, pulseaudio)
- fribidi, freetype, fontconfig development headers (for libass)
- libass
- FFmpeg libraries (libavutil libavcodec libavformat libswscale libpostproc)
- libjpeg
- libquvi if you want to play Youtube videos directly
- libx264 if you want to use encoding (has to be explicitly enabled when compiling ffmpeg)
Most of the above libraries are available in suitable versions on normal Linux distributions. However FFmpeg is an exception (distro versions may be too old to work at all or work well). For that reason you may want to use the separately available build wrapper (mpv-build) that first compiles FFmpeg libraries and libass, and then compiles the player statically linked against those.
If you are running Mac OSX and using homebrew we provide homebrew-mpv, an up to date formula that compiles mpv with sensible dependencies and defaults for OSX.
