Switch libavcodec audio decoding from avcodec_decode_audio3() to avcodec_decode_audio4(). Instead of decoding directly to the output buffer, the data is now copied from the libavcodec output packet, adding an extra memory copy (optimizing this would require some interface changes). After libavcodec added avcodec_decode_audio4() earlier, it dropped support for splitting large audio packets into output chunks of size AVCODEC_MAX_AUDIO_FRAME_SIZE or less. This caused a regression with the previous API: audio files with huge packets could fail to decode, as libavcodec refused to write into the AVCODEC_MAX_AUDIO_FRAME_SIZE buffer provided by mplayer2. This occurrend mainly with some lossless audio formats. This commit restores support for those files; there are now no fixed limits on packet size.
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.
