Yes that can be tricky so I always make sure I check the HDfury web GUI to see what is being sent. I’m the one who discovered the HDFury LLDV/Dolby Vision hack for HDR only displays/projectors and shared it with the world, so I know this well and check It often.
So the answer is, Infuse Pro only plays the HDR base layer of the DV rip so I’m only getting HDR10 and no DV, correct?
I do like the results of it with Dolby Vision forced on with Match Dynamic Range set to off. The AppleTV 4K does an exemplary job of mapping it to pseudo Dolby Vision but I’d love to feed it real DV if at all possible of course!
Unfortunately like the previous poster said, you're never going to get real DV from UHD rips on an AppleTV. The main issue is that the hardware is only capable of profile 5 DV, which is single layer and in a different color space from the profile 7 found on UHD disks. So even if you have an MEL title that you can safely convert to single layer, you're still likely to have color accuracy issues to the lack of a color space conversion between the different profiles. With tsMuxer, you can alter the source code (there are also compiled versions floating around) so that instead of spitting out profile 8 for single layer files, it would produce profile 5 files. People have used this for their ATV, but like I said, there are likely to be color issues.
I have ripped the movie The Meg to .mp4 DV single layer using DVDFab and it shows up as DV in the Infuse GUI and plays as such just fine. The colors seem the same as when I play the disc in my Sony X800M2. I’m an ISF Certified Calibrator amongst many other industry things for 30+ years so would notice if color was amiss. What color issue is it that I’m supposed to be looking for exactly?
The only reason I’m not satisfied at this point is due to the lack of ATMOS audio.
So am I reading right that the new Chromecast Google TV is capable of playing all DV profiles with MEL and FEL and ATMOS?
No every Atmos...
I can confirm that the new Chromecast with Google TV supports:
Dolby Vision Single Track Double Layer in P4, P5, P7 MEL/FEL, P8 profiles
Dolby Digital (AC3)
Dolby Digital Plus (EAC3)
Dolby Digital Plus + Dolby Atmos
DTS (only with Kodi)
DTS-ES Discrete/Matrix (only with Kodi)
PCM multichannel (only with Kodi)
Audio not supported:
Dolby TrueHD + Dolby Atmos
I don't have an Atmos ready AVR so I can't test too much, I don't know if it could be possible to convert the TrueHD stream to lossless MCPCM or EAC3 and maintain the Atmos layer.
About DV profile 7 FEL I'm now making some tests to determine if it's processing the FEL layer in the right way, but teh first test is passed.
