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.
