Phoronix: VA-API Video Decoding Support For Wayland

Just trying to hijack the thread: I just thought I might try out vaapi under Ubuntu 11.10 with Xorg edgers on a Lenovo X220 (sandy bridge). So vlc -v --ffmpeg-hw seems to work for simple movies, but my high quality films fail with only one garbled frame every 10 seconds or so:
I suppose it has something todo with "Stream with high frequencies VQ coding".Code:[0x286dcf0] dts decoder: DTS channels:6 samplerate:48000 bitrate:768000

Shouldn't they rather focus on getting their stuff fixed on X before moving to Wayland?

Word Nazi report: VDPAU stands for "Video Decode and Presentation API for Unix", you skipped "Presentation" in your article.
That's not very nice of you. But since nobody is interested in the actual topic here goes:Quote:

Unless their hardware actually can't handle such high bit-rates? Usually hardware decoders only support lower levels of quality. You should search the Intel site for a document with the limitations of your exact CPU.Quote:
