Any way to play 4K IPTV stream on Roku TV?

[flashls82 4]

I've been fiddling around with IPTV in exploring that as a longer-term solution for some stuff. It works pretty well straight out of the box on my Roku TV (i.e. just with a filtered m3u) with all except the handful of 4K channels, which always get into a transcoding loop that eventually fails. 720p/1080p channels seem to transcode as well, but they work fine. This is from a TS source coming from the IPTV provider, everything running on a UGREEN NAS via Docker with Intel QuickSync hardware acceleration working fine. Also tried running it through Threadfin/setting up as an HDHomerun tuner to see if that'd help, but had the same problem. These same 4K channels play fine on my laptop and on my iPhone/iPad, so this is purely something about getting the format the Roku TV will play.

I am guessing the problem here is that Roku TV wants 4K stuff in an H265 container, for whatever reason it can't handle the original TS file, Emby wants to put it into an H264 container, and it never works. 

But... has anyone had any success playing 4K IPTV files on the Roku app? Any ideas for things to try (e.g. in any processing I could have Threadfin do pre-Emby)? This isn't a huge deal but mildly annoying.

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

@ebrSure, here's a few transcode logs from trying to play one of the channels in question on my Roku TV, and a photo of the "stats for nerds" from my playing the same channel on my iPhone 30 seconds later (where it's doing a total direct stream).

I would try using VAAPI instead of QSV for your transcoding, just as a test.

To see if that will help with transcoding issues.

Because of these speeds, they should be over 1.0 just to keep up.

What do you have set for this option? It will default to 30. If you change this option to Yes does it start to work the same as iOS? The framerate of your media is 59.94 which is above the 30 the setting will start at as default.

@speechlesI did try setting this to "yes" and it still got stuck in a transcode loop. Honestly forget whether I had switched it back before I ran the test that generated the logs above but I can share some where it's definitely allowing 60fps if that might help. 

It's transcoding 1080p and 720p channels, too, though, and I'm not clear why it should need to especially since I'm now feeding it HLS to start with (the diffrence is at least those transcodes work fine).

[flashls82 4]

@NeminemI'll try that and report back. Do you have any idea why it needs to transcode in the first place, though? I thought Roku TV could do HLS 4K HEVC just fine.
