Call me skeptical. The reason is that FFMPEG's colour handling was pretty horrible last time I looked. This is legacy historical code issues, but they have prevailed up until recently. There are a few issues on the FFMPEG tracker regarding the colour handling. I'd be interested to see if gamuts other than REC.709 based are: 1. Correctly encoded to the stream. 2. Correctly decoded from the stream. The only workaround I was able to achieve was to manually handle the transform from the RGB encoding to the YCbCr domain, then manually encoding that. Even after all of that, the tagging wasn't handled correctly on FFMPEG's side IIRC. Wise folks like Kevin Wheatley can probably offer a little more insight here, given I believe he has mucked with the transfer function / coefficients nightmare in FFMPEG previously.
