Created attachment 63007 [details] dmesg, Xorg.log The GPU hangs when playing a MythTV recording. For 0.05 sec I hear sound but no display. This problem is reproducable. Using the normal MythTV display driver plays upto 720p fine, but 1080i content is not smooth, therefor trying VAAPI. Using Sandybridge 2600K over HDMI to a 1080i television. Using mythtv git 0.25-fixes with a dedicated X Server, no Desktop, on Ubuntu Server 12.04 LTS. Git kernel (>3.5-rc2), updated xorg-edgers. Immediately after: # cat /sys/kernel/debug/dri/0/i915_error_state no error state collected See attachments.

I tried to reproduce this issue on my Sandybridge but failed to run MythTV although I built fixes/0.25 branch successfully. Can you try other player, such as mplayer-vaapi ? You can fetch mplayer-vaapi via $> git clone git://gitorious.org/vaapi/mplayer.git -b hwaccel-vaapi Run mplayer with vaapi $> ./mplayer -vo vaapi <file>

Played the same recording over 20 times. After a random time (10sec - 15min) the picture started shaking. As mplayer uses a newer ffmpeg as mythtv. Compiling the same checkout version in mythtv failed. What I noticed with mplayer using -vo x11 (xv and xvmc didn't work), 10% of the tries the picture was OK and started shaking after a while too. 90% of the tries it shaked from the beginning. Not sure if it is similar as the "normal" display settings within mythtv, were I see the same behavior. I PM a link for the recording, 6GB, 1hrs, maybe you don't need all. Maybe you notice something in the recordings, as all recordings show the same behavior. Would be great to hear your experience. At the weekend I will install an NVidia Card (GT 9600) and check the behavior with vdpau. Angela
I can't reproduce the shaking issue on my machine.
I moved to NVidia GT9600, where also shaking existed. As the content is 1080i and my television is 1080i I had always deinterlacing disabled. When activating deinterlacing in Mythtv the problem vanished. I have not checked if enabling deinterlacing solves the issue on Intel GPU. The problem of the hanging GPU when using VAAPI has only be noticed with Mythtv as it uses an older revision of ffmpeg. Mplayer with VAAPI works (did not further investigate resolving the shaking when enabling deinterlacing). Thanks for helping me narrowing the problem down and hope to return to Intel/VAAPI as soon as Mythtv has updated ffmpeg. Angela
