Upstream first ! I don't see any submission over linux-media mailing list. I don't mind adding it, but with the assurance that it's going upstream. Looks good otherwise.

And now it's time to rebase:

Make sure that you submit the V4L2 update in a seperate patch, and that it's being taken from upstream.

Should be in 4.19:

Thanks, decoder support is now included. I have tested using staging drivers
for Amlogic S905x, but should work with any implementation.

For encoder support, I have files this one: https://bugzilla.gnome.org/show_bug.cgi?id=797141
