SOLVED: Video freezing on TV App

[f-d-ffm]

I tested reencoding my files in h.265 Level 4 Main. I did a short test and it seems to work (started to watch a movie and it went far beyond 1:40 min, I had to stop at 15 min because of an upcoming meeting). I'll do a long test tonight with a long movie and let you know if it worked.

Is there any way to get the information, what variations of a codec my TV Box can handle natively? I've read about adb commands (dumpsys media.player) but somehow jellyfin must know whether a client supports the codec or doesn't. Is there a way to get this information easily?

Also, is there an easy way/automated way to re-encode all videos? This will take me weeks to do manually.

Thanks a lot
