Hi Andy,

Thanks for the testing. I will look into the memory issue. For the cbr test, what was the bitrate you set? And by saying testing high rates, how high was the rate approximately?

Found VCE firmware Version: 52.4 Binary ID: 3

No luck I'm afraid. The above test will still hard lock me after about
30 seconds.

I also notice it's eating memory 2.6 gig by the time I lock.

Replace vaapih264enc with omxh264enc and all is OK, will run for ages no increasing memory usage. In fact I think this firmware & or kernel has fixed a powerplay omx issue - will update my bug for that when I have tested more.

FWIW the above test would make cqp with a qp of 0 - testing cbr does also leak/lock, though specifying bitrates does sort of work, the result is much higher than requested (maybe some framerate assumption - I am testing high rates.
