Public bug reported:
On YouTube, you can right-click the player and select "Show video info".
An information box pops up and you can see if the video is being played
back using hardware acceleration or software rendering. For me, it's
usually played back using software rendering, but I just now installed
the mplayer2 package, which depends on libvdpau1, and all of a sudden, I
got hardware-accelerated playback. However, this swaps all videos' red
and blue color channels. (Sky and water are red, and red things are
blue, and people kind of look like smurfs, but green things remain
green.)
Upon removing the libvdpau1 package, the videos go back to normal, with
red and blue in their proper place.
I am using Google Chrome, which uses its own bundled version of the
Flash plugin, but the problem also happens in Firefox which uses the
Flash plugin installed on the system. My graphics card is an Nvidia
GeForce GTX 580. No overclocking or funny business there though, just a
reference card.
