For ao_pulse, the current latency is not a good indicator of how soon the AO requires new data to avoid underflow. Add an internal pipe that can be used to wake up the input loop from select(), and make the pulseaudio main loop (which runs in a separate thread) use this mechanism when pulse requests more data. The wakeup signal currently contains no information about the reason for the wakup, but audio buffers are always filled when the event loop wakes up. Also, request a latency of 1 second from the Pulseaudio server. The default is normally significantly higher. We don't need low latency, while higher latency helps prevent underflows reduces need for wakeups.
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.
