It doesn't work flawlessly but seems better than last time i tested it. Firefox CPU usage seems kind of high with HD videos. At least it doesn't crash it.

Kind of off-topic, but can anybody give me a concise summary of the differences between VA-API and VDPAU? They both seem to be hardware-acceleration APIs, and most FOSS drivers end up supporting them both, so why do they both exist? Is it a ffmpeg/libav type of thing (basically the same with 90% of the differences being extremely minor)?

Unfotunately i still experience crashes with hd videos on youtube using proprietary nvidia blob (and libva-vdpau-driver)

There are actually four and all are pretty similar:

VDPAU - Decode only. Designed by nvidia. Currently supported by radeon, nouveau, nvidia drivers.
VA-API - Encode and Decode. Designed by Intel. Currently supported by intel driver.
OpenMAX - Encode and Decode. Multi-platform Khronos standard. Currently supported by radeon driver.
XvBA - Decode only. Designed by AMD. Currently supported by catalyst driver.

The main difference is who designed them. They tend to be somewhat tailored to the designer's hardware.

For me it doesn't crash. Quality isn't good. At least not consistent. I see some artifacts and its blur some times.

Bad:


Good:


+ a flickr on the screen each time i start a video.

Need to test more though. gst-play-1.0 is broken also.

Why use such roundabout way? Can't gstreamer use vdpau directly? There's a libgstvdpau.so in gst-plugins-bad.

gst-vaapi vs gst-omx?? radeon r600 works semi-OK with gst-vaapi.

An indication of CPU usage without the current CPU frequency is kind of useless you know. It could be 54% of CPU @ 774 Mhz vs. 114% of CPU @ 1.8 Ghz, that's not quite the same.

In case anyone that can do something reads here.

The quality issue is that when changing to the big player it doesn't use the 720p resolution but a smaller one. And when using the small player the quality is shit. Might has to do with scaling of the video or something. Not sure if this is a gst-vaapi issue or a youtube one.
