JellyFin keeps transcoding even if TV support the file format (LG WebOS)

[Fate]

First of all thanks for the clarifications and support!

> It seems like that file is a dolby vision file in mkv container. LG TVs won't Dolby Vision in MKV which will make the server to remux it. Your server should not transcode it and I think it is not. Still need the ffmpeg log to make sure though.

Here the pastebin of the transcode log (hope it is the log you asked for): https://pastebin.com/x4vbc7Wk
Where I can see if it is just a remux, or a transcode?
I suppose it is a transcode since the host CPU goes up to 80%.

Code:

Stream #0:0 -> #0:0 (hevc (native) -> h264 (libx264))
Stream #0:1 -> #0:1 (copy)

It's transcoding via CPU according to the log. I don't see the reason tho.
Apart from it not liking the hevc ....

If you look into the Admin->overview while playing the file on TV you should be able to see the transcode reason (click on the little i icon)
