Maybe update the Playback-Devices list?
It's been confirmed Apple TV and iOS devices can play BL+RPU with some conversion.
Or not, if that is considered conflicting to Dolby standards and rules
Apple TV can only play Dolby Vision P5 properly.

Infuse used to trigger Dolby Vision on TVs for some other profiles but it was only ever using the HDR10 base layer. They fixed it awhile back to stop triggering Dolby Vision on the display for those profiles.

If there is new information please link the source.
Sorry, I thought it's been confirmed last month. Maybe Im wrong.

Hum,
We’ll it plays doblyvision on my pc all trims as well & triggers pc dv.
Are the colors correct is a good question doe.
But I’ll test it on my appletv but I would say it should play on appletv.

Yes it plays on appletv & all the l/trims
And u can upload that to your apple tv library
Stream it from Mac m1 to Apple TV
Stream it form pc to Apple TV works
I don't use infuse on my iOS device. The native player (quicktime?) through File APP works just fine for me.
Does ATV have some file sharing app that can play video using the internal player through SMB?

@sw5163

Yes, upon checking mediainfo it shows Dolby Vision metadata but the file fails to play, same happened on a Hisense U7G so looks like ffmpeg breaks video with DV. TSMuxer with ts worked perfectly.
If it is not too much trouble, could you please show me what command you are using to generate DV mp4 with ffmpeg?
I would very much like to give it a try.
Im currently using ffmpeg dovi_tool mp4muxer and mp4box to generate DV mp4. The process is troublesome.
It will save a lot of effort, If ffmpeg alone can do it.
Many thanks.

I don't have apple tv but I have rechecked these files, I think they can still be downloaded.

Converted p8.1 sample:
https://drive.google.com/drive/folders/ ... sp=sharing
Anyone can make this with the following command:
ffmpeg -i p81_cmv29_tests.mkv -c copy cmv29.hevc
mp4muxer -i cmv29.hevc --dv-profile 5 --dvh1flag 0 -o cmv29.mp4
They can directly play by iPhone in safari and have dolby vision.
Im not sure about ATV, but l2 trim works in cmv29 on iOS devices.
Only saturation in l2 works in cmv40 since cmv40 has l8 for replacement, according to quietvoid.

did you try the old tsmuxer version that made fake p5 files?

if it works then you have your solution and it's much faster than the mp4muxer.

I have just tried it, unfortunately Apple's internal player has very poor compatibility. As far as I know, it only supports mp4 in hvc1 or dvh1 codec. And I don't have other player to test them, sorry.

Oh I don't nesscessarily use mp4muxer. I mentioned it because it's official tool.
I personally use ffmpeg to extract, dovi_tool to mux, and throw them including subtitle to mp4box. mp4box automatically generate P5 dvh1 by default no matter what the real profile is. The speed seems fine, like 5 min for 70G file. So it's not exactly that bad.

Could anyone with an ATV confirm what @manix said please?
if @sw5163 method works, then I'll update the "playback devices sheet" and make a workflow for Apple users in my DoVi_scripts

because we have conflicting information...

Tested the files cmv29.mp4 and cmv40.mp4 at my friend's who owns the ATV . The test was done using file explorer for mac (app) installed on the Atv and streaming directly from the Pc, so I think that apple internal player was used.
Both files played entirely in Dolby Vision without hassle.
Hope this can help RESET_9999

I saw the light changing frequently from dark to bright on both files.
So I think yes.

Also, I just noticed that the mp4 created by the latest mp4muxer works on the C2 while it's HDR10 only on the C8(we have to use the old mp4muxer).

Well, guess sometimes we need to break some rules.

Did you guys test infuse?
Theoretically, fake P5(HDR10 bl and RPU) in MKV should also play by infuse.
With mkv, it can have TrueHD, if ATV can properly handle it.

What do you mean? C2's internal player can also play FEL now? I thought only models before CX can do that.

No, I'm talking about P8.
the C8 (probably the C7/C9 too) cannot play the DV MP4 created by the latest version of the mp4muxer. We had to use the older/first version of the tool.
