Bug#747663: mpv: hwdev=vaapi has bad quality output

[Kurt Roeckx]

Package: mpv
Version: 0.3.9-1

Hi,

I've been using hwdec=vaapi for a while now and things looked
good.  Yesterday I upgraded from 0.3.8-1 to 0.3.9-1 and everything
I look at now looks really bad.  It seems that it starts good but
then as it's updating the quality gets worse and worse like it's
blurred.  Sometimes you suddenly see that it improves a lot, and I
guess that is when there is a new full frame or something.

I've only looked at h264 content, and full screen.

Commenting out the hwdec=vaapi from the config gives me back
normal quality.
