Patch

The VDPAU H.264 decoder violates the spec in the way it handles marking frames as unused for short-term reference. This results in corruption and playback errors for some videos. Here's an example video:

Patch attached.

Revised patch

Sorry, I managed to simultaneously implement the wrong part of the spec and "test" my changes with ffmpeg's decoder in my pipeline. *This* patch should be correct.

Edward, could you take a look at this? You touched these plugins last :)
Comment 3 Edward Hervey 2013-08-23 12:18:30 UTC 
Steven, do you still get this issue with 1.x ? the vdpau decoders changed quite extensively since.
Comment 4 Sebastian Dröge (slomo) 2013-08-23 12:34:09 UTC 
The patch still applies, so I assume it is still valid
Comment 5 Edward Hervey 2013-08-23 12:42:21 UTC 
Ok, will check it once the h264 decoder is activated then :)
