Ensure that chapters are sorted by time. There are some broken mkv
files that have chapters in random order. Using simple chapter
skipping with the seek_chapter slave command is very confusing and
just doesn't work if the chapters are not in order.
The chapters are resorted every time a chapter is added, that would
make the chapter list unsorted. While this is algorithmically very
stupid, it doesn't require changes per demuxer, or reasoning when
exactly chapters could be added. Turning this into an insertion sort
isn't worth the code, and the added demuxer_sort_chapters() function
could possibly be moved to the "right" place later.
This is not done when ordered chapters are used, because timeline
support uses different data structures for chapters.
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
- libfontconfig
- 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.
