I agree and I don't blame libvdpau for the actual bug.

The problem in this case is very likely caused by the Flash Player which sends U and V components in the wrong order (so the result is basically swapped red and blue colours). We should push Adobe to fix this, but so far all bug reports were closed with CannotReproduce or FeatureRemoved:

Pierre-Loup Griffais from Nvidia has actually created a patch for libvdpau, although it is very hacky: http://www.nvnews.net/vbulletin/showthread.php?p=2518770#post2518770

Since Flash Player is closed source and Adobe doesn't care, we can just workaround this problem, and libvdpau is one possible layer where to do this.
