RealMedia was listed as a format for which the internal demuxer
(demux_real) was preferred over lavf. The original reason for this
(lavf failing to give any timing information for some video frames)
has been fixed in libavformat since. Make demux_lavf the preferred
demuxer for RealMedia.
The libavformat demuxer does still have issues. COOK audio initially
misbehaves after a seek (inconsistent timestamps, audio remaining from
the before-seek position). However, the internal demuxer seemed to be
_consistently_ out of sync with a test file. I haven't done thorough
testing, but the internal demuxer does not seem less buggy.
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.
