Screenshot of AVC video with rendering error.
When mp4/AVC videos are played with Firefox's player the videos looks too light and pale.
By the looks of it they're rendered like they were full range videos, even though they're limited range videos.
Testing is easy:
Youtube has vp8/webm and avc/mp4 encodes of the same video. To test these can be downloaded with one of the numerous tools and then played back with firefox.
Anyone here?
Anyway... Update on the issue. If I disable "media.windows-media-foundation.use-dxva" I get proper video but naturally the CPU usage jumps up.
So it seems its something related to DXVA hardware acceleration.

This is a driver issue, I've asked nvidia for help but got nowhere.
