Changing the volume when softvol is enabled or if the audio output driver doesn't support volume controls causes insertion of the "volume" filter. This fails with AC3. Since the filter wasn't removed after that, and the filter chain was in a bogus state, random crashes occured past this point. Fix it by reinitializing the filter chain completely on failure. Volume controls simply won't work. (This can't be fixed, because AC3 is a compressed format, and would require additional decoding/encoding passes in order to support arbitrary volume changes.) This also affects balance controls.
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.
