Questions for VDPAU should probably go to either the Mesa list or the
VDPAU list, libva is completely unrelated to this.
Well is it possible that you just locked up the GPU? Please take a look
at /sys/kernel/debug/dri/0/radeon_fence_info and dmesg.

Christian.

Hi,
I have an application that renders by binding libva/vdpau surfaces
onto GLX pixmaps.Playback works ok for a while, but than the
application displays black frames after a few minutes of operation
(always reproducible within 1-15 minutes usually).
When this happens, gdb backtrace shows that the current call to
vdpau_PutSurface (done from the application) never returns. Are there
any obious reasons that would lead to vaPutSurface to never return
(e.g. some deadlock in libva/vdpau?)
Using vdpau driver on radeon.
