Dolby Vision Support in JRVR
TheShoe:
Question re: DV support -
Is the target goal to be able to fully support DV in JRVR and effectively streamed to the TV as HDR10? e.g. all the benefits of DV will be possible?
mlknez:
Excuse my ignorance, but I am still unsure about your MC 29 Dolby Vision support.
1. If i keep all of my movies in .iso containers, can MC still use Dolby Vision?
2. How will I know if it is using the Dolby Vision metadata or not if it doesn't bitstream the Dolby Vision to the Pre/Pro?
3. Can it still bitstream the Atmos audio if it isn't bitstreaming the Dolby Vision video, but just rendering it to HDR10 with the metadata?

These questions about DV keep being asked. :)
Dolby Vision playback is only supported on media files originating from streaming services. It is not supported for DV BluRay discs, and there are no plans to.
The display is not switched to DV mode for files for which there is support, either. What happens is that DV metadata is used to perform any "grading" of the video content, and the resulting HDR10 video content is sent to the display in HDR10 mode. What you will see is the same you would have seen on the display in DV mode.

I suppose that i don't quite understand the point of the Dolby Vision support then.
1. Most modern devices have support of Dolby Vision from STREAMING digital sources such as Netflix and Amazon Prime, built in. Therefore no need for JRiver MEDIA Center to do anything with it.
2. Nobody else supports DV from MEDIA on pc, so there IS a reason for JRiver MEDIA Center to support it. Competitive advantage
3. Most modern display devices support DV natively

Agree that most TV support DV (notable exception is Samsung) ... not aware of any projector that support DV
Agree ... that for streaming content ... no need for JRiver to do anything
Its a different story for UHD discs ... as i prefer running them off HDD ... plus iPhone ability to capture videos in DV might trigger my interest further (though atm i think its more of a gimmick)
Point 2 is unlikely ... as that requires a license from Dolby ... which (even if JRiver was interested in getting ... and they are not interested) Dolby will unlikely to provide as PC platform tends to be easier platform for reverse engineering ... not even streaming apps on PC have DV
And what ppl mean by DV support? ... pass DV metadata to display so display goes into DV mode ... or use DV metadata to do tonemapping?
For last one ... not aware of anybody able to do it ... as Dolby don't publish their DV spec publicly ... and reverse engineer of DV in US is likely not so legal
For first one ... its possible if you do app for Nvidia Shield ... Plex is able to do it ... also Plex running on my new Sony XR65X90J also able to trigger DV (EDIT: DV in mkv format generated by MakeMKV from UHD disc)
Be aware that currently Plex has major issue on their AndroidTV apps (Shield and my sony TV included) with Dolby TrueHD (including Atmos) for quite some time now ... and solution is nowhere in sight (they have tons of apps on different platforms ... supporting all of them is likely nightmare)
PS. honestly ... when i switch between DV and HDR10 on my sony (and it takes some time to do it) ... i can see the difference, but not sure which one is better ... unless i run these side by side, which i cannot do as i have only one Sony (i can run Sony with LG OLED side by side ... but likely whatever difference i see will be due to panel differences) ... so for me ... honestly ... atm running DV through Plex is more of placebo effect
