I just noticed that Plex client doesn't work without internet connection with local Plex server, wtf, Jellyfin came to the rescue.

Are .ts and mp4 dolby vision files streaming correctly via google drive > kodi with nvidia shield pro?

Can anybody tell more about the new Nokia Streaming box 8010 with Android TV 11 and when it'll be released? I'm curious to its performance.

there are no more 2 videofiles on rarbg with dolby vision movies (mkv remux). where is the dv-metadata in the files? is it from now on 1 videofile?

FEL can be either BL track+EL_RPU track or a single BL+EL+RPU track.
Dolby Vision is really complicated, you may want to do more research to learn how it actually works.

BL(base layer): an HDR10 2160p YCbCr 4:2:0 10-bit video.
Dolby Vision fall back to this when not supported.

EL(enhancement layer): an HDR10 1080p YCbCr 4:2:0 10-bit video.
Supported device use BL and EL to mux a final 4:2:2 12-bit video.

RPU(reference processing unit): To indicate how filmmaker would like the video to be separately shown on 100nitSDR/600nit/1000nit/10000nit display. (despite the actual brightness record in BL)

There are basically 4 types of Dolby Vision video:
Profile 5(streaming): ICtCp 4:2:0 10-bit video + RPU.
It uses a more efficient color coding, but appear green and purple on non support device.

Profile 8.1: BL+RPU
Profile 8.4: Dolby Vision shot on iPhone, HLG BL+RPU

FEL(Full Enhancement Layer)
Profile 7 DT_DL FEL: BL in one video track, EL+RPU in another video track.
Profile 7 ST_DL FEL: BL+EL+RPU in one same video track.

MEL(Minimum Enhancement Layer)
Profile 7 MEL: BL+RPU same as 8.1 just in bluray container.

Please don't hesitate to point out my mistake!

I don't think x264 supports HDR, so I'm assuming the 1080p track is a SDR one.

Thank you for your reply, and sorry for my late reply.

The 1080p files are indeed SDR.

I'm getting mixed results, researching online whether H.264 supports HDR or not. However, Wikipedia states the following:

Wikipedia wrote:Throughout the development of the standard, additional messages for containing supplemental enhancement information (SEI) have been developed. SEI messages can contain various types of data that indicate the timing of the video pictures or describe various properties of the coded video or how it can be used or enhanced. SEI messages are also defined that can contain arbitrary user-defined data. SEI messages do not affect the core decoding process, but can indicate how the video is recommended to be post-processed or displayed. Some other high-level properties of the video content are conveyed in video usability information (VUI), such as the indication of the color space for interpretation of the video content. As new color spaces have been developed, such as for high dynamic range and wide color gamut video, additional VUI identifiers have been added to indicate them.

I'm assuming this means H.264 supports HDR or?

sw5163 wrote: Sat Sep 03, 2022 6:54 pmIf that's the case, you can try muxing it into Profile 8.2 or Profile 9.

How would I go about converting to Profile 9? The dovi_tool github page doesn't seem to mention this.

I would like to at least give it a try, or I'll wait for / request a 1080p Web-DL with Dolby Vision... Unfortunately, the 1080p version of one of my favorite films objectively looks much better than it does in 2160p. It's so badly upscaled. Hence why I want to get the best of both worlds.

If you want perfect accurate image:
You will first need to modify those "reshaping data" in RPU for SDR->HDR. (basically impossible)

sw5163 wrote: Tue Sep 06, 2022 12:28 am From my understanding, P5 RPU has "reshaping data" for ICtCp->YCbCr.
P8.1 RPU doesn't need "reshaping data" for HDR10->HDR10.
P8.4 RPU has "reshaping data" for HLG->PQ.
P7 RPU has "reshaping data" for processing the weird colour in EL (I'm not sure what it really does)

If just using P8.1 RPU, the result is very likely to be wrong.
And then you will need to find a way to inject-rpu into h.264, I don't think current build of dovi_tool supports that. But im sure Dolby in their lab can do it.
Once you get an SDR+RPU track, it's easy to remux it in mp4muxer.

If you are willing to accept some minor quality loss with re-encoding:
You could just put the h.264 track into PremierePro/LumaFusion/FinalCut/iMovie (Apple actually provides pretty good remapping algorithm for SDR->DV since they collaborate with Dolby) and re-encoding it to P8.1.

you're right. i've got dolby vision on elvis with the program of reset_9999. While elvis had 1 videotrack in the mkv remux file. thnx. learnt again.

Hi do anyone still have their Ugoos am6/b plus and can test/confirm if it does 3d either MVC/iso playback?
Many thanks.

Is anyone familiar with a project called DoViBaker? https://github.com/erazortt/DoViBaker

My understanding from the project description is that this project claims to merge FEL into the BL. Now, I am not super familiar with all improvements reported here in this mega-thread, but if this is correct, would the resulting file allow us to take advantage of FEL improvements on devices that can't handle the FEL info directly?

Thanks, I had to reinstall Plex couple of months ago and I forgot about this option, now I added it back in the form of "192.168.1.0/24", it will turn out next time whether it works.
