Any idea what part of FFMPEG/Xuggle controls the color, and what might be
the correct setting to mitigate it?
Before people jump all over this, I've already looked into this on
Xuggle and we're just passing in YUV data (gotten from a
av_decode_video call) to av_encode_video(...), so my guess it's some
setting in the MP4 encoder. I think Stas' question is better phrased
as:
"Are there settings in the mpeg4 encoder that can affect color saturation".
I would actually suspect a decoder issue. Stas didn't say in what player
he made the screenshots? I have encountered something like this in the
past with MPEG-2 or DV sources as I recall. The issue was something in
Quicktime decoding/displaying the video differently to FFmpeg or
libmpeg2 or so. I don't remember precisely what it was, maybe Baptiste
knows of some issue in Quicktime.
