Known bug, when converting MPlayer confuses rgb555 and bgr555 when converting to yuv.
The problem is that fixing it would mean breaking conversion the other way round, from
yuv to rgb since there ffmpeg's libswscale is broken and confuses the two formats...
Probably the later case does not matter to you, so you can 'fix' it by swapping the
RGB555/BGR555 return lines in fmt-conversion.h
