Whenever the demuxer is accessed to retrieve metadata, use the newly
introduced master_demuxer field instead. If a timeline is used, the
master_demuxer will still refer to the main file, instead to segments.
Instead of mpctx->demuxer->stream, access mpctx->stream; even though
they are the same, the code becomes shorter. For the TV code, introduce
a function get_tvh() to access the TV handle, instead of duplicating the
code all over the place. Often the demuxer field is checked to determine
whether something is currently played; prefer other methods over that.
Note that the code before always accessed the current timeline segment,
and would e.g. read file metadata of the current segment. Now it always
returns metadata for the master file. This may have various wanted and
unwanted effects.
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.
