FWIW this is something I added, hoping it was going to get used at some point, but I never followed up with support in xf86-video-nouveau for Xv. At this point, I'm not sure I ever will. I encoded the "enabled" part into the value with a high bit (1<<24) -- not sure that was such a great idea. All NVIDIA hardware supports colorkey (and not actual alpha, until the very latest GPUs - Volta/Turing families), although my implementation only covers the pre-G80 series (i.e. DX9 and earlier GPUs - pre-2008). Should a determination of usefulness be reached, it would be easy to implement on the remainder though.
Cheers,

nouveau already has something for colorkey: https://drmdb.emersion.fr/properties/4008636142/colorkey
I know this is marked "not for merge", but it would be nice to discuss with them and come up with a standardized property. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
