Please describe your bug

My media files with HVEC 4K HDR video tracks and DTS audio tracks aren't switching my device into HDR mode any longer. All of those files need to go through audio track transcoding, as my device isn't capable of playing DTS tracks.

This used to work thanks to https://github.com/jellyfin/jellyfin/pull/7325 until 10.8.0-beta2. It stopped working since 10.8.0-beta3 and still doesn't work with 10.8.0 and 10.8.1.

It still works if the media file is fully capable of direct play. So, using the same media files with HVEC 4K HDR video tracks but switching to an AC3 Dolby Digital audio track will switch the device into HDR mode as expected.

Please let me know if you need further information.

It's exactly the same issue as described in https://github.com/jellyfin/jellyfin/issues/7295, hence why I mentioned a regression and linked the issue. Sorry for not being clear about it. Please let me know if any further information is missing.

@stoically are you trying to say that you lost HDR? your audio track has nothing to do with this transcode according to your logs. if the issue is "HDR data lost for no reason when transcoding" then it should just be called something like that. as is this issue is very confusing to interpret.

Like, all I can say is that the symptoms are the same as in #7295, but obviously I shouldn't try to open an issue with a diagnosis of the issue source if I'm not familiar with the code base. It is related to the audio track tho, since DTS tracks cause the issue while it works fine with AC3. Also, with Jellyfin Server version 10.8.0-beta2, the media file from the log (DTS audio track) does switch the device into HDR still, so it is a regression somehow.

For completeness sake I'm also attaching the log for the same media file but playing with Jellyfin Server version 10.8.0-beta2. It also has the "Starting transcoding because currentTranscodingIndex=null" entry, so that seems unrelated. However, we can see that ffmpeg is only transcoding audio, not video - compared to the log showing the issue in the initial description.

Same problem with 10.8.8. When I play a movie with Direct Play (video and audio is supported) HDR works. If I switch to an unsupported audio stream during video playback and the video stream is also encoded due to the current bug, HDR is gone and the TV switches to SDR. I am using the Webos client on my LG C2. Let me know if I can give you more information.
