Dolby Vision now possible through MP4 Mux.

I don't know why you're quiet about it but you should scream out loud that you updated your DV tools to generate DV metadata for ANY HDR10 MOVIE using madVR measurements lol

+1 , amazing work, just generated a profile 08.06 from an HDR10 sample, plays fine with internal Plex app: 04-2160p_23fps_dovi_p81-l_s02e01_cyan_error.ts

Tested some files on the new FireTV Stick 4K Max.
Still has trouble with HDR10+ ending up with a black screen when Dolby Vision is triggered.

Just noticed the new Firestick 4K Max has grey letterbox bars with cropped Dolby Vision content.
Not cool, since it can also mean L2 is ignored.

Is this with from official apps as well (ATV+, Disney+, etc)?
That's a problem, probably never will be fixed

By the way, since now the Firestick 4K Max allows disabling HDR.
Playing profile 5 files results in proper SDR colors.

What do you mean about this? Does it do DoVi HDR to SDR tonemapping?

Edit: what happens with the "min_pq" L1 metadata during madmeasure2RPU generation? Will it be always 0? (I don't think that madvr's bin file has any info about it.)
Edit2: sample uploaded

I don't know since I'm not subscribed to ATV+ currently. Disney+ does not crop their video.
What's interesting though is that Hulu serves both HDR10+ and DoVi together and there were no complaints.

Yes, profile 5 files get tonemapped to SDR and look fine.

min_pq is always set to 0. This is the same behavior as the HDR10+ derived generation.

edit: I just tested the L2 and it's not ignored at least..

Ok, I tried this route and now x800m2 can successfully switch to DV.

However, after pressing “Display”, it shows that the output resolution is only 1080p and not 4K (even though x800m2 list the source as 4K DV). When testing the original UHD, x800m2 can successfully output 4K.

I’m confused on what went wrong. From my understanding, since UHD DV are dual layers, I included the 1080p layer when remuxing into a new m2ts when using tsmuxeR.

What version of tsmuxer are you using? At one stage only nightly versions worked, I don't know if that has changed but here's the version I've been using:

Have you tried playing the newly created files off a drive?
You're right, both layers should be left as is.

Connected x800m2 directly to TV instead of receiver fixed the issue. Guess it’s a bandwidth issue? Interesting that remuxed m2ts apparently takes up more bandwidth than UHD.

Do you have a "4K Signal Format" setting on your AVR? If so, is it set to "Enhanced"?

Oh wow, that’s it. Thanks!
These AV hardware keeps surprising me with important settings buried in menus lol.

wow, so they removed the ability to play properly DV cropped content on the new Firestick, that is a really stupid move since everything on iTunes or Prime is cropped.
The last time I checked , HULU content is not cropped as well. (they have ridiculously low bitrate though )

Yeah, I'm not sure if I'll bother switching to the 2018 model though. I only noticed the grey bars with fades to black.

Anyways, it made me create a cropped test sample for the important metadata: https://mega.nz/file/8YsRRKJa#_g_vX2voc ... raveYPpiIA
With this everything seems to work fine otherwise.

credits to FF.de for the original HDR10+ test sample, from which I used the different L1 metadata.

haha, trust me you will.
Having this exact problem with my x700, I just can't stand the grey black bars(especially the 1600px content). I even prefer my Shield with the red push for p8 cropped content(no red push with p5).

interesting thanks... will try on my x700.
that sample has very small black bars though

[FubbAyH]

That's a great sample @quietvoid. It's very interesting to see examples of all the DV adjustments, because until now I've always been a little bit vague about exactly what the DV metadata can do.

[NiCE77]

Would you be able to try one of the titles where the FEL is obvious (e.g. Power Rangers or Total Recall) to see if it is being used?

that's because I did those samples with tsmuxer and it breaks something in the RPU when you split the file. I didn't know about that back then.
As @FubbAyH said, the ending credits of Power Ranger is a better way to verify if FEL is processed.

The credits are grey like HDR10, so nothing new.

And what about the Fire TV Cube (2019)? The Amlogic S922 SoC is able to decoding FEL.

I don't know, I don't own a FireTV Cube.

Thanks for your Great work on Dovi.
Have you compiled an update Kodi version for the Firestick 4k (original not the Max)?
I am using the version available in Fandango's Matrix 19 Final

[juzer7]

Guys, question.

I'm re-encoding some of my UHD Remuxes. I wanto to inject then RPU into re-encoded BL.
This way I can easily create MKV files with Dolby Vision Profile 8. Playing flawlessly on my Shield 2019 Pro.

But what if I wanted to create a file that I could play directly on different TVs? I just used mp4muxer to create DoVi Profile 8 mp4. However it plays well on my Shield but not on my LG OLED B9. (which I did not expcted as this TV is able to play MP4 Profile 7)

So what container and DoVi Profile should I choose if I want to create a file being able to be playd directly on TVs? At leat on LG OLED we are using in our family?
MP4? TS? M2TS? What profile?
I want this file to be able to be played on TV, Shield and Android mobile devices. If there is no DoVi compatibility then it would be good if the file is played as HDR. That's why I think the only format BL+RPU with HDR compatibility is Profile 8?

Maybe I can mux them into Profile 7 with some "fake" EL layer? Profile 7 MP4s play fine on my LG OLED and Android mobile devices.

Thx for help.

I build my own but it's running Kodi 20 Nexus, and doesn't include all binary addons.
You can find it here: https://mega.nz/file/4BVTTAoI#KBpPwfQZ1 ... cjlh62Bh-s
The code branch is this https://github.com/quietvoid/xbmc/tree/ ... oska_build

I think Maven's builds might be better for you though, from here: https://www.kodinerds.net/index.php/Thr ... ür-Android
Both are probably a different package name.
