Stream #0:0(eng): Video: hevc (Main 10), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 3840x1600, SAR 1:1 DAR 12:5, 23.98 fps, 23.98 tbr, 1k tbn (default)
...
Stream mapping:
Stream #0:0 -> #0:0 (hevc (native) -> h264 (h264_qsv))
...
Stream #0:0: Video: h264, qsv(tv, bt709, progressive), 3840x1600 [SAR 1:1 DAR 12:5], q=2-31, 35291 kb/s, 23.98 fps, 90k tbn (default)
Here, even with the lowest bit rate specififed in the Jellyfin Roku app, it doesn't get transcoded down in resolution (and the bit rate isn't 1mbps). It stays 4k, which the TV doesn't support. (The Roku TVs have Roku built into the hardware - so you don't get the option to specifiy a resolution.)
It seems like something is awry when it comes to setting a bandwidth limit and the resulting transcoding experience -- but not on all Roku TVs. Just on that one Roku platform (low end TCL).
Just my observations!
This sounds like a bug and you should definitely submit an issue on the Roku app github.
