Always test with the latest version from the v4l-utils git repo (git://linuxtv.org/v4l-utils.git). v4l2-compliance is continually improved, so driver testing should always be done with the latest version. For the JPEG encoder you can add the -s option to v4l2-compliance. Unfortunately, the streaming tests for JPEG decoders in v4l2-compliance are not well supported at the moment, so you can't use -s there. Please provide the full output of the v4l2-compliance command as well, I'd like to see the actual output. Thank you very much for working on this, always nice to see new HW support.
