Converting Dolby Vision to HDR10

[Neuron5]

If you have a capable Jellyfin server that supports HEVC 10 bit, Jellyfin will tone map your profile 5 video to SDR on-the-fly.

I am running with Intel® UHD Graphics 730 so I think I should be able to do this. How do I enable it? I have transcoding enabled and playing on Android TV. It was direct playing and video was black. VPP Tone mapping is enabled in my settings.

In the Android TV settings (not Jellyfin), go to Display & Sound > Dynamic range & Color format. What is reported there?

Here are the settings

Try remuxing the video into a MP4 container if it is in a MKV. I vaguely recall DV5 working better in MP4.

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +genpts+igndts -i "/path/to/dv5/video.mkv" -map 0 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled newFile.mp4

Thanks I will try that.

However I think something is up with my Jellyfin client or server settings. Probably unrelated to this thread.

Here is video stream that plex is able to play on the same device but I am getting the same black screen on Jellyfin. Plex dashboard shows this as 4K DoVi/HDR10.

Code:

Need to spend some time and do some reading on this to see what I need to fix in my Jellyfin setup.

This one is Dolby Vision profile 7. The updated guide would work on this video for converting to plain HDR10.

Right, I was going to try that. But I got curious as Plex is able to play this without issues on the same device and Jellyfin is not. So I wanted to research that a bit more to see if I can get a better understanding of what is happening. For the most part stuff just works so when it does not I am a bit lost .

If "some device" you mentioned is the amazon stick, then that is purely that device has a terrible native player implementation. Plex implemented their own player backend instead of just using the system exoplayer to workaround a lot of device quirks.

[Neuron5]

Its a nvidia shield player. Not the latest model. Custom player explains it, probably the same is happening on my device as well.

Good afternoon, I tried searching but could not find anything. Is there a way to use this on an unraid server?
