Roku and Max Bitrate UHD - ryder42 - 2025-06-22
Hi--
I just got a Roku Ultra LT (2023) and have it hooked up to ethernet on my home network.
I have the 3.0.5 Jellyfin app for it. My current issue is trying to direct play 4K HEVC movies. My current guess is that it's a bandwith issue, because when the videos do transcode the reason is that the "current video bitrate is not supported."
I think this is a client-Roku issue, so if anyone knows, off the bat, if this model of Roku can handle the bitrate of 4K UHD movies streamed with direct play, I would be very grateful! Because of what I think is the bitrate issue client side, the server attempts to transcode and gives this error "ffmpeg exits with code 0" (see below). I have set all the settings on the app to play the codec and I have a 4K HDR tv.

RE: Roku and Max Bitrate UHD - ryder42 - 2025-06-22
So I found on Reddit that if you go to users you can uncheck boxes that allow the client to play media requires transcoding (so another way to force the direct play).
I actually got the movies to direct play but then I realized that I couldn't fast forward. Ok, not a big deal. Then I started getting some bright light visual artefacts and after more digging I think my MKV containers are the problem. And this could be why I was having such issues direct playing or transcoding.
