Please post start the series from the bindings. In your next iteration, make sure to include full v4l2-compliance report in your cover letter since we cannot assume maintainers. In addition to this, we now ask for fluster scores for each of your supported decoders. We expect the results to have no timeout, and ideally the error/failure explained (aka unsupported resolution, profile, subsampling, bit depth, etc.). Note that inter-resolution change is not possible with V4L2 today, so no need to explain why these VP9 tests fails. Fluster supports V4L2 decoding through GStreamer (gst-launch + video4linux plugin) and FFMPEG at the moment. It will run through ITU conformance vectors for HEVC and H.264, and run through libvpx and and chromium test vectors for VP9. https://github.com/fluendo/fluster regards, Nicolas > > > > > Dikshita
