Dolby Vision

[Sammy 794]

I am not exactly sure if I should put this here or in the server sub thread.

 

I use Emby for Windows server beta and generally keep it up-to-date every time there is a new update.

I also use Google TV devices such as the ONN Google TV or a native Google TV app built into the TV when playing Dolby Vision files.

Sometimes they fail completely or sometimes I get the green and purple hues. Other times they play fine. This seems to be file specific and occurs on TV's that don't natively support Dolby Vision.

Is this due to encoding or an issue with transcoding or an issue with the playback device?

Hi.  The ones that work have an HDR fallback and the ones that don't work, don't.

So fallback is encoded in the mkv?

 

It was a 43" TV in my bar so I just updated it to a Hisense TV that supports Dolby Vision. The 24" in the kitchen isn't worth the bother..

Provide mediainfo from one that works and one that doesn't, it will be apparent if it has an HDR fallback - the profile tells the story.

I took a peak at the Media Info and see the difference in the video. One says HDR 10 Compatible and the other doesn't. I don't suppose Handbrake can reencode Dolby Vision to HDR 10. Not that it matters, I just went ahead and sprung for another TV in the bar and the kitchen TV isn't used to watch 4k stuff anyhow because who wants to watch much on a 24" screen anyhow..

I am not sure that it can because I've never used it, might be able to generate one based on DV data though.

I was referring to this for the profiles, for example this is a 7.6 with DV and HDR (typically bluray):

Quote

HDR format                               : Dolby Vision, Version 1.0, Profile 7.6, dvhe.07.06, BL+EL+RPU, no metadata compression, Blu-ray compatible / SMPTE ST 2094 App 4, Version HDR10+ Profile B, HDR10+ Profile B compatible

Or an 8.1 (typically streaming):

Quote

HDR format                               : Dolby Vision, Version 1.0, Profile 8.1, dvhe.08.06, BL+RPU, no metadata compression, HDR10 compatible / SMPTE ST 2094 App 4, Version HDR10+ Profile B, HDR10+ Profile B compatible

Or 5, pure DV

Quote

HDR format                               : Dolby Vision, Version 1.0, Profile 5, dvhe.05.06, BL+RPU, no metadata compression

Yep, as seen in your media info, the one that plays is 8.1 (has fallback) and the one that doesn't is 5 (pure DV - no fallback).

[Sammy 794]

I'm not thinking any "free" solution will convert this such as Handbreak or MKVToolNix..

Plus that's a bunch of work. A new TV that supports DV is the better solution!

[Lessaj 543]

I believe it can be done with dovi_tool but requires a re-encode, so it's a little bit of a lossy process, but feasible. New TV does sound better though.
