The OSD couldn't be updated at all without frame stepping. This made the VO unusable (In fact, vo_x11 should never be used, but it's provided as fail-safe fallback). Implement VOCTRL_REDRAW_FRAME to deal with this. Unfortunately, this exposes issues with draw_bmp's subtitle rendering: areas that are not covered by subtitles at all are changed as well. The "backup" mechanism provided by draw_bmp doesn't copy these areas, which turns up as quite visible artifacts. (These are included when taking screenshots too.)
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 (for libass) - libfontconfig (for libass) - 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.
