Dolby Vision now possible through MP4 Mux.

[realbabilu]

go read the past weeks in this thread, all the test have been done and confirmed that the appletv only support genuine p5 DV. ( i dont know about other apple devices)

Finally i got one sample working perfectly that coming with Profile 05.06.
I compare DV test remux with Dovi_Script mp4muxer+mp4box and Subler for mac with subtitles.
The Dovi_Script with mp4box last subtitles muxing detect DV but can't detect the Dolby Atmos (only Dolby Audio DD+). The TV will detect Atmos if it use only mp4muxer (no integrated subtitles mux).
The Subler for mac integrated subtitles but my TV can detect the Dolby Atmos and Dolby Vision. It mux faster then mp4muxer.
Just share my experience.

Q, has there been any work done for colorspace conversion for DV profile 5 to HDR10 or SDR? There's plenty of work on tonemapping HDR10 to SDR, but wondering about for DV content on non DV devices.

Of course, it has been supported in libplacebo and mpv for a while now.
Also, Jellyfin has beta support for real time transcoding: https://www.reddit.com/r/jellyfin/comme ... is_coming/

Hey, this is new to me. Am I right to assume you mean the cli player https://github.com/mpv-player/mpv ??
Or is there a GUI player too that can tonemap P5 DV to HDR/SDR?

Yes, that mpv. It is a GUI player.
You can also try mpv.net: https://github.com/stax76/mpv.net

For Dolby Vision tone mapping, you need to use vo=gpu-next in the config. Or with the --vo=gpu-next flag in CLI.

Thanks quietvoid. V5.8.0.0-beta working like a charm with DV P5 (I'm on win 7).

[EDIT] Later version mpvnet 6.0.3.0 also working.

Is there some trick to enabling lossless audio in Plex on the Ugoos AM6B Plus? Lossless audio works in Kodi. Oddly, the 32-bit Kodinerds build seems to discard the Full Enhancement Layer in Dolby Vision, even though Plex plays it perfectly. If I can just get lossless audio working in Plex, I will finally achieve full Dolby Vision (FEL) playback.

With Ugoos AM6 plus/Kodi Matrix DV edition (thanks @Fandangos and @quietvoid) Saving Private Ryan (MKV DV) no flicKering like the m2ts on Sony X700.
This is the first time that a device (except Sony X700) does not flickers on this film.
I tried Firestick 4K, Shield 2019 and Google Chromecast with Google TV.
In Ugoos (latest firmware 0.40) also HD audio (True HD Atmos and DTS X) works in passtrough in Kodi.
My soundbar confirms.

Can you please share a link to that specific Kodi build that did not produce flickering for the opening of Saving Private Ryan? For some reason, I get flickering on my Ugoos AM6B Plus in Kodinerds, but not in Plex.

I've tested the Ugoos AM6 Plus media player (Amlogic S922X-J), and it seems, the internal player correctly processing the Full Enhancement Layer from DTDL mp4 file!

I'm tried with Kodi 19 custom build and working same with the P7 STDL mkv too!

Can you please share a link to this custom Kodi build? Kodinerds discards the Full Enhancement Layer on my Ugoos AM6B Plus, but Plex does not.

[JoseTheBae]

I got PLEX to trigger both DV and Atmos in a MKV container and for the 5 minutes I watched (power rangers), it was perfectly stable. AVR showed lossless Atmos.
but once again when I stopped playback and started it again, back to lpcm stereo and no more DV. Just gotta wait for a ugoos update, I just sent them another email.

What Plex Client version was this on? I can't get Plex to output lossless audio on my Ugoos AM6B Plus.

no particular version. I was able to make it work about 3-4 times and it just seem to work randomly.

[JoseTheBae]

I downloaded the modified ExoPlayer build, which I made Kodi's default player. Unfortunately, playback stutters a lot, although it does appear to be processing the Full Enhancement Layer. Is there some other player with smoother Dolby Vision playback, or perhaps a newer version of ExoPlayer?

Sorry, I no longer own the Ugoos. It was quite unstable.

The 32-bit (ARM) build? I believe I tried that and still got flickering (using PlexKodiConnect), but I will give it another try.

Looks like the 2022 LG TVs handle L5 slightly differently. ( I don't know about 2020-2021 models)
Also, list of movies with incorrect L5. And some streaming web-dl have static Dolby Vision...
