Did anyone get AV1 codec to work via Jellyfin? I can play the file over a USB stick connected directly to the Roku, but just getting audio only when playing via Jellyfin.
I think there's an option in the roku Jellyfin app to enable AV1 playback. I haven't tried it myself, but I have seen it messing around with a few settings.
Could be, I have a Roku built in to my TCL TVs, that's what I use. Did you replace an existing file with the av1? I had to rescan my library after swapping my files for it to work, otherwise it gave a playback error.
