Using -demuxer mpegts -correct-pts triggered the assertion in ds_get_packet2(). This is not surprising, because the correct-pts code was changed to accept _complete_ packets, while all the old demuxers (including the mpegts demuxer) require you to use "partial" packet reads, together with the video_read_frame(). (That function actually parses video frames, so fragments of the original "packets" can be fed to the decoder.) However, it returns out demux_ts packet's are mostly useable. demux_ts still adds an offset (i.e. ds->buffer_pos != 0) to the packets when calling internal parser functions, such as in parse_es.c. While this is unclean design due to mplayer's old video demuxing/decoding path, it can be easily be made work by modifying the packet as returned by ds_get_packet2(). We also have to change the packet freeing code, as demux_packet->buffer doesn't have to point to the start of the memory allocation anymore. MPlayer handles this "correctly" because it doesn't have a function that reads a complete packet.
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.
