Issues with Dolby Vision

[simonmarkis]

Hello,

   I'm having difficulty playing back a Dolby Vision movie on my TV, which does support it. The client is an xbox series X, using the native jellyfin app, server is hosted on truenas scale. I have hardware enabled for H264, HEVC, MPEG2 and AV1. Prefer OS native DXVA enabled, hardware encoding enabled, VPP and regular tone mapping enabled. 
   The TV does say that it's showing HDR10 (not dolby vision) content, but it still looks really dull. According to the playback info, the video's bitrate is not supported and video's range type is not supported. I'm attaching the transcode log.

I've tried disabling tone mapping and DXVA setting but with no success.

You did not state what GPU you are using for hardware acceleration, but since you enabled VPP tonemapping I can only assume it is Intel.
You'd need to add hardware support for HEVC 10bit as well. Enable hardware decoding for all but VP8.

Also, is your TV an LG, and your movie in an MKV container? Because apparently there are issues with that combination with DV.

You did not post the log either. But the reason it looks dull is that tonemapping is not being done correctly, but it should not have to tonemap since it should direct play, unless limitation mentioned above.

Hmm odd that log didn't get attached, I'll try again once I get home. I don't have a dedicated GPU, the nas has intel 14600k, so its intel iGPU UHD 770. The TV is TCL but the movie is indeed in an MKV container. 
What I'm having difficulty understanding is why does it feel the need to transcode in general. The TV is capable of playing Dolby Vision so in theory it should just be direct playback.

I see, well the UHD 770 is quite capable, so even if it has to transcode it will look alright.
I won't speculate further into why the server is transcoding instead of direct playing, as I don't have experience with DV myself, I've got a Samsung TV, so all my DV content falls back to HDR.

I run Jellyfin on Truenas Scale too, so the only natural question is, you enabled the option to pass through the gpu when you set it up yes?
Otherwise, all I can think of is that you failed to enable support for the HEVC 10bit format? Assuming that the content is encoded in HEVC 10bit of course.

Once you get around to posting the log I'll have a look and see if anything pops out.

Trying to attach log file here, apparently .log is not allowed here so .txt it is.

The weird part is that it's playing direct on my phone just fine.

The only thing I can see that pops out is that you've limited the bitrate on your client, which forces transcoding, it is set to 12mbps according to the log, while the movie has a bitrate of 62330 kb/s.
Hit the gearwheel icon in the player and set the bitrate to Auto, does it direct play now?
