Video which should reproduce the bug: http://www.filedropper.com/sample_5 Did some more testing and this problem only happens for videos with a certain aspect ratio, file type doesn't matter. The size of the video in the previous comment is 620 x 480, another video with the same problem is 700 x 576. I can reproduce this issue on G45 just use the video you uploaded As I suspected, this is a regression from 2.10.0, bisecting lead to this: cb06aa32d433f54affe87da2cf964f0308d3c258 is the first bad commit commit cb06aa32d433f54affe87da2cf964f0308d3c258 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Mar 1 22:57:39 2010 +0100 Xv: fixup XvMC on i915 I've accidentally broken i915 xvmc due to alignment constrains that break my assumption that Y-pitch == UV-pitch*2. Fix this up by consistenly using dstPitch2 for the Y-pitch. This also unifies the dst pitch computation slightly, now that the i915 xvmc special case is gone.

Reverting the implicated commit resolves the issue. Created attachment 34802 [details] [review] fix chroma pitch on gen4 and later Can you please test the attached patch? The patch works for me, thanks! Solves the issue here as well. Thanks. |

Created attachment 34601 [details] screenshot of the bug Some H264 videos are completely corrupt when played back using textured video . I'm attaching a screenshot of the bug, and a short video which should be enough to reproduce the problem. I think this is a regression, I will do some more testing and a bisect if possible.
