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
Yes.
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)
No.
