Sounds like a power management problem to me. Could you bisect?

I'm not completely confident that I marked every bad commit, but I got this:
c4120d55ffa44746584a8a1e5b00cb7eafc006ff is the first bad commit

drm/amdgpu: use begin/end_use for UVD power/clock gating
This fixes turning power and clock on when it is actually needed.

Also the decodebin element uses vaapi to decode the video, so I may have
mischaracterized the bug in the first place that it's really an UVD problem.

So does something like below work?
for X in $(seq 1 50); do gst-launch-1.0 -e filesrc
location=big_buck_bunny_720p_1mb.mp4 ! qtdemux ! avdec_h264 ! videoconvert !
omxh264enc ! fakesink; done
My Tonga used to have this issue and this post prompted me to look what fixed
it =
it was a recent tonga firmware upgrade so not much use to you, also I think
power gating for uvd/vce is disabled for tonga - so maybe another difference.
While the issue existed I could work around by forcing my clocks to high when
testing vce =
echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level
then
echo auto > /sys/class/drm/card0/device/power_dpm_force_performance_level
after testing finished to keep thinks cooler :-) (note that if you change modes
or your monitor goes into dpms this will happen anyway)
