PS, 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
bye bye HDR10
Because I haven't had the chance to test it. Some of madVR's scenes are very small and might cause flashes.
I guess it works the same way as the dynamic target nits algo works for HDR to SDR ? I mean both are based on madvr algo that measures pixels.
If so, I'm using 113b with my PJ (the last version before the time-limited build, I think) and there are rarely any flashes visible ( 98% of movies are fine) so it should be fine. I didn't try yet but I will this weekend.
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.
They clearly mention supporting Dolby Vision both in MEL and FEL. They also mention using the ‘latest Realtek RTD1619DR’.
Is there a chance they might actually play the full FEL layer instead of just downgrading it to MEL?
I won't get my hopes up. The RTD1619DR is the same chipset that is used in Zidoo's latest generation of devices where it provides support for everything DV except the video data in the FEL (it automatically downgrades to MEL). I guess it's possible that Zappiti have reverse engineered profile 7 to play the full FEL, but since that would be truly unique, I'd expect them to spell that out very explicitly in the marketing if they had done so.
Makes sense. So is the RTD1619DR ‘limited’ or is it capable but just not ‘allowed’ by Dolby to use the full FEL data?

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.
That would make sense. Although, the players aren’t cheap at all (cheapest one of the new ones is $900 USD) so maybe there’s a small chance they were able to include it (they either payed for the license specifically for FEL or they reversed engineered it like you mentioned)?
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.

Doesn’t have the physical capability to process 2 video streams simultaneously- Confirmed by Zidoo devs, Dune players have the same chipset also and they just process RPU and disregard FEL also.

And you are right, even if the hardware can be hacked like the AM6+ The picture doesn’t look correct because Dolby will not modify and provide the SDK for a Media player, Dolby consider the MKV format to be the embodiment of piracy.

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.

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.

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.
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.
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?

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.
