vf_screenshot checked for a list of pixel formats that were known to work with swscale. However, the list was incomplete. If a pixel format was used that was not on the vf_screenshot list, but was supported both by swscale and the VO driver, mplayer2 would insert a useless scale filter to convert to a format supported by vf_screenshot. Fix this by making vf_screenshot check directly whether the pixel format is supported by swscale with sws_isSupportedInput().
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.
