Hi Jernej,

I have create a branch to test this series with VP9 and HEVC:
https://gitlab.collabora.com/benjamin.gaignard/for-upstream/-/tree/10bit_imx8m
Feel free to pick what I may need in it.

That doesn't improve fluster scores, I think more dev are still needed in GST
before getting something fully functional.
Anyway I able to select P010 pixel format if the input is a 10bit bitstream.

Regards,
Benjamin
