 As there are more and more Cameras able to record with more than 8 bit per
 pixel and there already are programs like Shotcut and Blender which
 support high-precision internal processing, e.g. blender is unable to
 handle 10-bit videos properly, because converting a 16 bit buffer from the
 sws yuv to rgb conversion to its internal 32bit buffer would be too slow
 and therefore it has to use an 8 bit buffer.
 If ffmpeg could convert to 32bit directly, there wouldn't be the need to
 do two conversion steps, 10 ->16->32 and native high precision video
 support would be much easier to implement!
