Using vf_screenshot on Libav printed useless/misleading error messages
when playing 10 bit h264 with a VO that supports 8 bit yuv420p only:
Unsupported format 444p14le
Unsupported format 444p14be
...
The cause of this is that vf_scale is inserted to handle the format
conversion, and tries to find a pixel format with best quality. This
includes the 14 bit and 12 bit formats, which don't exist on Libav.
vf_screenshot tries to query whether Libav's libswscale supports it,
resulting in these error messages. (In theory, vf_scale is missing this
check, but it doesn't matter in practice.)
Since this warning is rather useless anyway, because all input video
comes from libavcodec, and only the conversion into the other could
possibly fail. Silence the warning by raising it to verbose message
level.
Closes #7.

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.
