Some audio outputs don't provide access to a system-wide mixer control, and do per-application audio mixing. Further, some of these forget the volume as soon as the audio device is closed. This can be annoying, because mplayer will "forget" the volume when playing a new file or when crossing ordered chapter boundaries. Support restoring the volume on audio reinitialization if an audio output driver knowingly behaves this way. (This doesn't change that mplayer never writes any settings into the config file, including volume settings.) This commit doesn't yet change any actual output driver to use this code. Hopefully make some logic in the volume restore code a bit more robust.
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.
