Can you try 'v4l2-compliance -s'? Note that this may not work since I know that v4l2-compliance doesn't work all that well with codecs, but I am curious what the output is when you try streaming. Don't bother trying to chase down reported failures, those are likely from v4l2-compliance itself. It is something I would like to improve, but -ENOTIME. Regards, Hans
