I'm opening a new email because color has nothing to do with the<br>
Vdpau/Vaapi issues.<br>
It was just an attempt to put together all the information on how<br>
CinGG treats color. Lately I found emails from Hermann Vosseler that<br>
are very indicative. However, the fact remains that each plugins of<br>
CinGG treats the color in its own way, so we should find a way to<br>
understand how all the native plugins act, one by one (if I'm not<br>
mistaken, the plugins of ffmpeg clip everything to 8-bit and sRGB).<br>
Only with this information can we reconstruct a chain of steps that<br>
accounts for color transformations and, perhaps, keep them under<br>
control.<br>

Hermann already knew in 2012 that it was not possible to treat it in<br>
CinCV and that's also why he went for Lumiera.<br>
