yeah, @manix can be hard to follow sometimes...
do you have an mp4 version of quietvoid's L2 trim test file that works on the appleTV?

Re: Dolby Vision now possible through MP4 Mux.
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.RESET_9999 wrote: ↑Fri Jul 15, 2022 12:22 am@sw5163

They can directly play by iPhone in safari and have dolby vision.sw5163 wrote: ↑Mon Jun 27, 2022 1:50 amConverted p8.1 sample:

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
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.

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

Re: Dolby Vision now possible through MP4 Mux.
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.RESET_9999 wrote: ↑Fri Jul 15, 2022 12:47 amdid you try the old tsmuxer version that made fake p5 files?

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.

Re: Dolby Vision now possible through MP4 Mux.
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...

Re: Dolby Vision now possible through MP4 Mux.
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.RESET_9999 wrote: ↑Fri Jul 15, 2022 2:35 pmCould anyone with an ATV confirm what @manix said please?

Both files played entirely in Dolby Vision without hassle.
Hope this can help RESET_9999

Re: Dolby Vision now possible through MP4 Mux.
I saw the light changing frequently from dark to bright on both files.
So I think yes.

Re: Dolby Vision now possible through MP4 Mux.
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).

Re: Dolby Vision now possible through MP4 Mux.
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.
Re: Dolby Vision now possible through MP4 Mux.
What do you mean? C2's internal player can also play FEL now? I thought only models before CX can do that.RESET_9999 wrote: ↑Sat Jul 16, 2022 12:40 amAlso, 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).

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.

Re: Dolby Vision now possible through MP4 Mux.
appleTV should be able to handle "fake p5" mp4 with LPCM.
