libx264rgb only advertises BGR0, BGR24, and RGB24 as supported formats. 

I think it would have GBRP as a supported format if it really converted to that prior to encoding.



ffmpeg.exe would insert swscale, though I don't think libavcodec does. Could be wrong.



However, ffprobe detects the bitstream as GBRP..
