[RFC 0/2] VP8 stateless V4L2 encoding uAPI + driver

[Andrzej Pietrasiewicz]

Dear All,

This two-patch series adds uAPI for stateless VP8 encoding
and an accompanying driver using it.

It has been tested on an rk3399 board and there exists
a gstreamer user:

https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3736

example pipeline:

gst-launch-1.0 videotestsrc num-buffers=500 ! video/x-raw,width=640,height=480 \
! v4l2slvp8enc ! queue ! matroskamux ! filesink location=test_vp8.mkv

I kindly ask for comments.

Notably, the documentation for the added uAPI is missing,
that is to be addressed when sending a patch series proper (not RFC).

For the RFC I also did not care to replace a BUG_ON() in the boolean encoder.

Rebased onto v6.2.

Regards,

Andrzej
