I have seen the audio, but no video issue, and they were malformed MKV files. Remuxing them resolved the issue
Then there should be an appropriate error message. I’ll look into it, thanks.
this, only DV files i can play with plex are ones ripped from blurays that have the dual profile but like mentioned, its not “real DV”… everything else is rather “playback not supported” or all i hear is the audio
@Ridley @DaveBinM
This is not working properly.
I have tested with multiple files now. Some files play but the TV is not put into DV mode but HDR mode and some files have the spinner and sound or spinner for some time and then an error.
ALL of those files play perfectly on the Sony Plex app.
I then subscribed to infuse and tested all files on Infuse on the AppleTV and they ALL work fine, everything plays, TV is put into DV mode.

Ditto!
I encounter the same situation - after reporting it about 1.5 year(!) ago here.
Also, I really do not understand this technical back and forth that is going on here since many months.
To me the situation is quite easy: there is a lot of DV encoded videos out there that the AppleTV Plex app cannot properly play (s. many, many messages above) and the TV native versions of Plex (LG in my case) have absolutely no problem playing (at least for me.)
@Ridley and @DaveBinM: should we understand that even though so many of us seem to have this problem and demo files were submitted over the last few months, the Plex team has not been able to replicate the issue, nail down the cause by comparing how e.g. the AppleTV Plex vs. the LG Plex handle these files, and come up with an analysis plus solution proposal?
I would really appreciate to get information that is stepping away from the nitty gritty and answer the above (for me) fundamental questions. Or show me where and why my points are wrong…
Thanks and best regards.

@Ridley any updates to share?
Same here.
All demo files are guaranteed to work with Apple’s native player, should also work on PLEX. They can also be directly played in Safari and have Dolby Vision.
9.1.6 eac3+atmos:

3. mp4mux(bento4) to merge them:

This is great stuff, thank you!!
Regarding Profile 5 in MKV containers…
It doesn’t seem like ffmpeg or mp4box support EAC3+Atmos muxing. So while Dolby Vision works on Apple TV 4K, Lossy Atmos does not work after remuxing from mkv to mp4. (Both Dolby Vision and Atmos work correctly when playing Dolby’s sample mp4 files)
Dolby’s mp4muxer is capable of correctly muxing EAC3+Atmos, but the output mp4 doesn’t play on an Apple TV, even when using the --dvh1flag 0
Do you know if there’s a way to remux both DV Profile 5 and EAC3+Atmos from mkv to mp4 without losing atmos?
@Ridley Any update would be appreciated, thank you.
P5 should work fine in DP and DS in the current public versions of the iOS and tvOS apps, with the exception of certain MP4 files muxed with the dvhe codec tag, which may fail to DP. You can work around this for the affected files by disabling DP; this will be fixed in an upcoming release.
If you find cases where this still isn’t working (even when disabling DP), then I’m once again going to need iOS logs, PMS logs, and a sample file.

Thank you for the update.
Unfortunately I did not find a single file that worked properly.
What does DP and DS stand for?
Direct Play and Direct Stream
as opposed to situations where transcoding is necessary.
Well, at least you should have no difficulty reproducing your issue to obtain logs.

Apparently your QA ppl do have difficulty…
Anyhow I just sent you server and client logs with debug enabled. Please note that only on the third play did I enable debug lvl on the client side, so scroll down 
The file did DS, convert mkv to mp4.
The file (all files) play properly on a) the Sony Android TV Plex app directly on the TV and b) the infuse app on the aTV, infuse also direct plays the file.
If you can provide a place where I can upload a 9G file, I’ll happily share that, or if you can provide a proper ffmpeg call, I can share a smaller file, alternatively I can add you to the plex server and you can DL it via api call.
Thank you for your time @Ridley
Edit: the file name is ‘not.working.mkv’

I think that is related to this.
mp4box currently doesn’t support atmos packaging.
Could you please try:
ffmpeg -i mkv.mkv -map 0:1 -c copy atmos_by_ffmpeg.mp4
and play it directly in Apple’s native player without video.
If the receiver show PCM/Atmos or something like that it means ffmpeg supports eac3+atmos. Then try to mux that with DV video:
mp4box -add dv.hevc -add atmos_by_ffmpeg.mp4 -new dv_atmos_ffmpeg.mp4
ormp4box -add dv.hevc atmos_by_ffmpeg.mp4
to see if mp4box will parse the atmos track untouched.
The latter will directly add dv.hevc into atmos_by_ffmpeg.mp4
If above doesn’t work, please try:
mp4muxer -i atmos.ec3 -o atmos.mp4
mp4box -add dv.hevc -add atmos.mp4 -new p5.dvh1.atmos.ec3.mp4
ormp4box -add dv.hevc atmos.mp4
to see if mp4box will parse the atmos track untouched.
If that fails, the last chance would be mp4mux - Bento4
- Command line is probably this:
mp4mux(bento4) --track dv.hevc#dv_profile=5,frame_rate=23.976 --track atmos.ec3 bento4sample.mp4
It’s the tool I used before mp4muxer and mp4box.
I haven’t used it for a long time and it has frame_rate mismatch issue.
I don’t have an atmos capable device, so will need you guys to test.
Please let me know if these workflows work or not, many thanks.
Wait, I don’t use INFUSE, but can’t INFUSE play eac3/atmos mkv properly?

Thanks, I’ll try this tomorrow evening.
For anyone watching this thread, “Subler” for MacOS has so far been perfect at remuxing to mp4 while retaining Dolby vision and atmos data.
Yes, Infuse will play eac3 atmos from either mkv or mp4
