Yes, I made several DV AV1 samples with the original files for comparison: https://drive.google.com/drive/folders/1HQmWPa5D6s288-GeWU1l8z2GV-CZ9sZ5?usp=drive_link In my case, my TV set is probably compatible (TCL C825) since I find these lines...

I was able to test my test files with a TCL C845X2 TV with Just (Video) Player and Jellyfin Android TV 0.16.10 (in direct playback) and they were all detected...

OK, thank you for your comments. This is way beyond my knowledge :)
