Are you guys running mplayer with external ffmpeg enabled? Because mkv files fail to play on mine with some ffmpeg related error, even after I did recompile ffmpeg with "vdpau" USE-flag

It fails too. Here is the log:

try my line, without all the rest, maybe any of the other params is the issue.

also what gpu are you using?

True, it works with your line. However it sometimes isn't really smooth, while xv isn't lagging at all. I use HD5470

No artifacts at all, but it seems like it's struggling to give a constant fps sometimes

It's working when I try without all the options I've used before. However with XV output the video is smoother

Guys, you are not using GPU decoding.

VDPAU has two stages -- decoding and presentation. The presentation stage is essentially the same as XVideo, it does the scaling, colour conversion, etc. That's what you get with "-vo vdpau" instead of "-vo xv". The decoding is done by ffmpeg on the CPU, as always, just the video output is through vdpau.

XVideo is much more mature than the Gallium vdpau implementation, so no wonder that it's a bit smoother.

To turn on the decoding part of vdpau, you have to use "-vc ffmpeg12vdpau" as well. It only works with MPEG2 atm, won't work with DivX or h264

From Christian himself (http://phoronix.com/forums/showthread.php?52837-Gallium3D-VDPAU-On-Radeon-Starts-Working/page7):

Only MPEG2 works at the moment. Motion Compensation, iDCT and some other goodies.

MPEG4 (including h264) require more complex stuff that's not done yet.

I'd like to link to this thread because I found it really useful:

32bit driver ebuilds for amd64.

Just remember that you need to use the "pic" flag for mesa and turn off collision protection.

I was having some problems trying to emerge mesa-9999 and libdrm-9999 using the ebuilds from Funtoo's Experimental branch, (which I'll now report over there). However, using the x11 overlay, I was able to emerge mesa-9999, libdrm-9999, and xf86-video-ati-9999, successfully.

Thanks..

Just emerged mesa-9999 without problem

DaggyStyle · Watchman Joined: 22 Mar 2006 Posts: 5909

can any of you emerge libdrm-9999 or xf86-video-ati-9999?

Once I switched to the x11 overlay, I was able to emerge all three correctly using the overlay's ebuilds.

Thanks..

Emerged mesa-9999 libdrm-9999 and xf86-video-ati-9999 without problem, I am using standard ebuild from x11 overlay.

I don't get it, I use the packages directly from the overlay (I don't like layman) but I get this freaking error:
