Hi Ming,

For the patchset:

Tested-By: Nicolas Dufresne <nicolas.dufresne@collabora.com>

I've validated encoding manually with GStreamer:

  gst-launch-1.0 videotestsrc num-buffers=100 ! v4l2h264enc !
video/x-h264,profile=main,level=\(string\)2 ! h264parse ! qtmux ! filesink
location=test.mov

I've also verify the that the number of frames was exactly 100, this is common
issue with V4L2 encoders. Then I have validated VP8, H.264 and H.265
decoders
using fluster [0] with this PR [1] applied. You can find full summary at the end
of this email. Markdown report didn't get generated, I will have to check with
upstream fluster if there is a regression.

$> ./fluster.py run -s -so amphion-imx8qxp-conformance.md -d
GStreamer-VP8-V4L2-Gst1.0 GStreamer-H.264-V4L2-Gst1.0
GStreamer-H.265-V4L2-Gst1.0

VP8:   Ran 59/61 tests successfully               in 131.788 secs
H.264: Ran 75/135 tests successfully               in 501.206 secs
H.265: Ran 126/147 tests successfully               in 1131.933 secs

Note that in mainline, only 1 core get fired and is kept at its lowest possible
frequency, so perhaps it may cause some of the timeout seen. The driver is
overall functional, and I would like to thank you for this extra work. Also,
note that this very first time I run Fluster over the stateful CODEC wrappers. I
will need to run this on more platforms to locate the GStreamer specific fail.

VP8 note, conformance vector vp80-03-segmentation-1425 cause a hang but it
then
recover:
