The fact that a few frames are shown proves that VLC is NOT trying to use a non-existent XVideo. There would be no frames at all then. Makes sense. The fact that it works just fine when plain X11 output is forced in the preferences proves that X11 would work fine, but is not attempted with default settings. In other words, the problem lies with the OpenGL drivers. I have a similar problem on a laptop also with AMD/ATI chip (although mine has XVideo working fine so hardly a problem). This apparent regression is probably due to VLC using shaders for YUV color space conversion since version 2.0.0. I doubt VLC is at fault here, and I fail to see what else it could do. If shaders are so slow, the driver should not offer them in the first place. Why do you think the problem is that 'shaders are slow'? Without knowing where VLC is hanging, and/or at least seeing the output of glxinfo, don't expect any progress solving this problem. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Debian, X and DRI developer -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of unsubscribe.

That's the main difference between OpenGL in VLC 1.1 and VLC 2.0, version against which the bug was filed. It's also what I'm experiencing with my own ATI chip. In any case, since plain X11 works, I gather that VLC is able to decode the video just fine and the CPU is powerful enough, even with the extra color space conversion and resolution scaling for unaccelerated X11 output. -- Rémi Denis-Courmont Sent from my collocated server -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of unsubscribe.

I doubt the problem is that 'shaders are slow'. In particular, there's no reason why the shaders would suddenly be slower in consecutive frames when they obviously managed to render the first frame quickly. It rather sounds like VLC stops decoding / rendering after the first frame (few frames?) for some reason.

Bug#672972: Wheezy: VLC player can't play videos
I am having a similar problem here using Debian (Sid/Unstable) using an ATI Radeon 9000 on a 32 bit IBM compatible computer. The VLC player shows the first frame and does not proceed any further. On the same machine mplayer2 works just fine and plays the same video. There must be something different in the way that the vlc player and mplayer2 handle the video. Maybe it would be useful if vlc could be configured to use the mplayer2 video handling code.
