jdewoody71 8 Posted March 28, 2023 Share Posted March 28, 2023 Hello! Earlier this year I switched to a Roku Ultra 4K for my living room. Every time we play a video in Emby that is encoded in H.265, I have to select transcoding or most of the video is bright red/orange. My network setup is fully wired with CAT6 and 1GB switches. I have tone mapping enabled in Emby and my TV supports HDR. Here is the media info from one of the files: Any thoughts? Thanks. Link to comment Share on other sites More sharing options...

ebr 14925 Posted March 30, 2023 Share Posted March 30, 2023 If you don't select the subtitles, does it direct play? Link to comment Share on other sites More sharing options...

Right well this one is going to have to transcode, right? I don't think there's any other way, so we're going to have to make sure it transcodes automatically.

I have a Skystream Max (Android box) that I can play this on and I don't have to transcode. I also have several other H.265 series with this same issue when played on the Roku.

You may want to visit the Roku support site. There seems to be some issues with Roku's switching modes for HDR color spaces automatically.....

Android and Roku are completely different devices/systems with different capabilities. Yes, correct. It direct played after turning off the subtitles but the color is still off unless I switch to transcode as shown in my video sample. No, it is not an HDR item. I'm aware that they are different. I was just pointing out how it plays on Emby using a different device. Thanks. 1 Link to comment Share on other sites More sharing options...

speechles 1920 Posted March 31, 2023 Share Posted March 31, 2023 (edited) It is a problem with certain Roku models. It will misinterpret the color flag. You have to manually alter the header of the MKV to remove that color information like mentioned in the thread above. Roku has still not corrected this on their end. https://community.roku.com/t5/Channels-viewing/Severe-color-contrast-distortion-while-Plex-streaming-HEVC-EAC3-videos/m-p/634403 Edited March 31, 2023 by speechles 2 Link to comment Share on other sites More sharing options...

The issue is resolved with Roku firmware 12 update. No Apple TV necessary. 1 Link to comment Share on other sites More sharing options...
