That's a good question. I don't know if the hardware would be capable of simultaneously decoding the extra HEVC stream with the FEL video, but I think the main problem is that it's not allowed. My understanding is that since profile 7 is only found on UHDBD discs, Dolby will only licence the decoding code to be used in UHDBD players.
That's a shame, but thank you very much for checking.
Still, I definitely don’t disagree with what you said. And it wouldn’t surprise me if it still downgrades FEL to MEL after all. I’ll keep an eye out to see the results once they are released but I’m not getting my hopes up too much.
Dolby Vision now possible through MP4 Mux.

Re: Dolby Vision now possible through MP4 Mux.
Trying to get Dolby Vision m2ts to play on x800m2 but running into issues. Would really appreciate some tips/help.
Here is what I have tried:
1. Use MakeMKV to get Dolby Vision MKV.
2. Use eac3to to extract Atmos track(thd+ac3) from the MKV.
3. Use tsmuxeR to mux the MKV from 1) and Atmos track from 2) together into .m2ts file.
However, when I try to play the resulting m2ts file on x800m2 via DLNA(wifi), I just get a black screen and DV is not working. If I turn off DV in the x800m2 settings, then the m2ts just play in SDR, not even falling back to HDR10.

Re: Dolby Vision now possible through MP4 Mux.
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.

Have you tried opening the backed up m2ts file in tsmuxer and creating a new ts/m2ts file? That's what I do when I want to play DV files on my x700, there's no need to create a mkv file.mamelem wrote: ↑Fri Oct 08, 2021 6:20 pmTrying to get Dolby Vision m2ts to play on x800m2 but running into issues.

Re: Dolby Vision now possible through MP4 Mux.
I've downloaded two different 4K web-dls, one is a DV mp4 file and the other is a HDR mkv file with an added lossless track. I'm trying to use both to create a DV file with lossless audio.
I use this ffmpeg command:
ffmpeg -i File.mp4 -c:v copy -vbsf hevc_mp4toannexb -f hevc Out.hevc
To extract the video from the DV mp4 file, I then add that file to tsmuxer along with the mkv file (deselecting the mkv video) and I'm left with the DV video file and the lossless audio. I created both a ts file and a m2ts file as a test, the newly created files don't show as having a video track in mkvtoolnix or VLC player. I tested a couple of minutes using my X700 and they play perfectly but with grey bars.
I'm hoping someone can answer these questions.
1: Does the video track not showing in mkvtoolnix and VLC indicate a problem or is it normal?
2: Is there a better way to extract the DV video track from the mp4 file? tsmuxer doesn't open the mp4 file.
3: I've read profile 5 DV plays back perfectly on the Shield Pro 2019, no colour issues or grey bars. Can someone confirm this?
4: Can the grey bars cause burn in?

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.

Is this with from official apps as well (ATV+, Disney+, etc)?
That's a problem, probably never will be fixed
![Smile :)](./images/smilies/icon_smile.gif)
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
Re: Dolby Vision now possible through MP4 Mux.
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..

Re: Dolby Vision now possible through MP4 Mux.
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:mamelem wrote: ↑Sat Oct 09, 2021 7:13 amOk, I tried this route and now x800m2 can successfully switch to DV.

Re: Dolby Vision now possible through MP4 Mux.
Connected x800m2 directly to TV instead of receiver fixed the issue. Guess it’s a bandwidth issue?

Re: Dolby Vision now possible through MP4 Mux.
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 )
Sorry for my English.

Yeah, I'm not sure if I'll bother switching to the 2018 model though.

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.
