Dolby Vision now possible through MP4 Mux.

Posting this on behalf of someone else:

Anyone have experience with Zappiti (https://www.zappiti.com) or Zidoo (https://www.zidoo.tv) players regarding DV FEL support?

Zappiti claims to have FEL support: https://www.zappiti.com/zappiti-reference-dolby-vision

But sound support is lacking https://zappiti.uservoice.com/forums/31 ... by-true-hd

Also a discussion from the Zidoo forum http://forum.zidoo.tv/index.php?threads ... ack.87108/

Seems like they can handle FEL but only utilize the RPU layer.

(Both Zappiti and Zidoo is based on Realtek RTD1619 and also found Dune HD https://www.dune-hd.com)

Or is the conclusion that Chinoppo is still the only player that properly support FEL playback?

Thanks.

this is a little off topic, but libplacebo from videolan now has dolby vision profile 5 and 8 tone mapping support (I believe). Bluray's live in the profile 7 world, but I find this interesting overall.

I believe that no one can decode FEL at the moment in MKV (oppo can decode bluray images). the ones that claim FEL support just means they don't choke on FEL.

Amazing news, thanks @quietvoid for the contribution again!

Ugoos AM6+ has a 2nd decoder so is able to playback FEl (from dual track mp4) but it's a very buggy player.

You may want to ask yourself how many tv's support full 12 bit processing. And then yet, those 12bit colors will be downscaled within max luminance capacity of the screen. TBH, I think that nowadays tv's will not hit enough nits to even support 10 bit to its full brightness.

Thanks for the replies above guys.

Even though Ugoos / Am6+ can display FEL titles they don’t have a Dolby Vision SDK so it isn’t actually accurate so a waste of time.

Don’t forget a lo to of recent Fel titles have contained significant picture detail in the enhancement layer, it isn’t always just 2 bits of extra colour in the Fel layer.

Can either the Oppo 203 or 205 do anything the Sony X700 can't as far as DV BL+FEL+RPU? From what I've read, the Oppo supports ISO whereas the X700 only supports BDMV folders. I also read the X700 supports BDMV folders via USB only and not LAN. Not sure about the Oppo?

Thanks.

Hi folks,

i have a problem with the process to get an DV MP4 file running on the Apple TV 4k with iOS 15 and the latest Infuse release from the App-Store.

What i've done:
- Ripped the entire UHD Blu Ray with MakeMKV
- Extracted the M2TS File with TsMuxR
- Extracted the base Layer and the enhanced Layer from the M2TS file with `ffmpeg -i 00801.m2ts -c copy -map 0:0 bl.hevc -c copy -map 0:1 el.hevc`
- Extracted the RPU from the el.hevc with `./dovi_tool extract-rpu -i el.hevc -o rpu.bin`
- Re-Injected the RPU to the bl.hevc with `./dovi_tool inject-rpu -i bl.hevc --rpu-in rpu.bin -o bl.rpu.full.hevc`
- Created a MP4 File with `./mp4muxer_mac -o full.rpu.mp4 -i bl.rpu.full.hevc -i aud1.ac3 --media-lang deu -i aud2.ac3 --media-lang eng --dv-profile 5`

Infuse recognizes the File as DV File but when a start playback the TV shows only HDR. Here are the metadata informations of the final output file:

You're trying to trick Infuse to think the file is profile 5 when it's not.
The Apple TV only supports profile 5 and profile 8.4, which are not HDR10.

[staknhalo]

profile 8.4

I wonder if they'll try to do OTA Dolby Vision in USA/Canada with HLG being part of ATSC 3.0?

What steps have i to do to make the file to a Profile 5 file? I thought that was these two steps

- Re-Injected the RPU to the bl.hevc with `./dovi_tool inject-rpu -i bl.hevc --rpu-in rpu.bin -o bl.rpu.full.hevc`
- Created a MP4 File with `./mp4muxer_mac -o full.rpu.mp4 -i bl.rpu.full.hevc -i aud1.ac3 --media-lang deu -i aud2.ac3 --media-lang eng --dv-profile 5`

You can't, the video is still HDR10.

Okay, so that means at the moment it is not possible to create a backup of a Dolby Vision UHD BD to play on AppleTV with Dolby Vision, correct.

Thanks and regards

Following up on this, I think this is correct but trying to figure out why this is the case? It's not the color space conversion, but for some reason the RPU can't be created? Why can't the RPU from a profile 8/7 be put on a profile 5 stream? Does it changed based on the color space or something? @yusescope said something about it here but I don't fully understand why - viewtopic.php?style=6&f=12&t=18602&start=2445#p90215
