It's designed for all versions, but it has only been tested with 1.4 receivers. You can find it here: https://git.linuxtv.org/hverkuil/media_tree.git/log/?h=tc358840 BTW, don't wait for the follow-up review w.r.t. colorimetry, it might take 1-2 weeks before I get around to that, I need to carve out time for that. Feel free to post a v2 based on the current review. Regards, Hans
