HDR to HDR Tonemapping Swiftfin

[perrinpages]

Hello,

When streaming transcoded video on swiftfin, the video looks washed out on the default player on an HDR capable device. HDR is working when the native player and direct stream are enabled. Is there a way to force jellyfin to transcode to HDR? Is this a swiftfin limitation? I don't want tone mapping.

What kind of HDR is the video?

It's HDR10 in an mp4 container

I think it is the limitation of the vlc player and you have to use the native player for HDR playback unfortunately.

If you want to have better HDR support and don't mind use 3rd party client, you can try SenPlayer which has better HDR playback but that is more of a media player with Jellyfin support than a jellyfin client.

It also happens with the native player. The only time HDR works is when direct play is forced on the native player.

I guess the swiftfin profile is way too conservative. What you can do is:

- Just use safari. It will play this file with HDR.
- Use 3rd party client like I mentioned before, which provides better HDR capabilities than Swiftfin

The web client errors out so I can only use swiftfin…’file format not supported by this client’ but I can download the original file and it’ll play in safari natively because it’s a fast start mp4. I would rather not use a 3rd party client because they always have issues with downmixing multi channel audio.
