Macroblocks when DXVA is active
Posted: 11 Oct 2010 23:58
Since VLC added DXVA ability to ATI cards I've been using it with no problems.
Today I was rewatching this video I ripped, and it gets a lot of macroblocks when DXVA is activated. Nothing happens when DXVA is disabled, it plays as smooth as ever was.
Video info:
1 minute sample: http://www.megaupload.com/?d=3AVPZIPM (no audio to make it smaller)
It's very notable on the golf scene and when the power goes out.
I don't know what might be happening. The bitrate is very low compared with full HD videos I play fine.
