Code from libavformat's demuxer.
Merged by wm4. It looks like the byte stream writer API is private in
newer ffmpeg, so use the macros from <libavutil/intreadwrite.h>
instead.
It's not really known how to correctly set the field that is used by
the decoder to calculate the length of the last frame. The original
patch used:
put_le32(&b, (demuxer->movi_end - demuxer->movi_start) * sh_a->samplerate);
This doesn't seem to be correct. Write 0 instead. This is also
incorrect, but better than writing an essentially random value.
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.
Libraries specific to particular video output methods
(you'll want at least one of VDPAU, GL or Xv):
- libvdpau (for VDPAU output, best choice for NVIDIA cards)
- libGL (OpenGL output)
- libXv (XVideo output)
general:
- libasound (ALSA audio output)
- various general X development libraries
- libfreetype (for libass)
- libfontconfig (for libass)
- libass
- FFmpeg libraries (libavutil libavcodec libavformat libswscale libpostproc)
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 that first compiles FFmpeg libraries
and libass, and then compiles the player statically linked against those.
