“Smart Youtube TV” app plays HDR on youtube on Nvidia shield.
the 2019 Shield pro is now as good as it gets for a one stop shop, unless you like APTV interface more.
I was not aware a third party app would allow HDR for YouTUbe on Shield. How is this achieved? I was under the impression that it was hardware limitation. I guess it’s possible to use some sort of software decoding to achieve this? Either way, I’m going to have to look in to that app and make my “smart” TV dumb, finally.
Sorry !
Rectifying my post, i meant 4K, you are right, there is no HDR on Shield (it’s a device limitation in regards to the VP9…)
Apologies.
This was exceptionally helpful in understanding the current situation. Thank you for posting it.
I’m going to hope against hope that a future Apple TV may support at least TrueHD out and hopefully Atmos over TrueHD as well but won’t be holding my breath. But hey, stranger things have happened. Maybe we’ve got some Plex fans on the tvOS team? 
So is the consensus here that Plex and/or Infuse will never be able to transcode TrueHD Atmos to EAC3/DD+/MAT 2.0? It would be nice if we could at least get lossy Atmos. I could live with that.

What I still don’t understand is how come Netflix and iTunes can output EAC3 5.1 with Atmos but Plex can’t?
The only reasonable conclusion I see is that there is some proprietary Atmos Audio API components which aren’t available for all devs.
I’d love for the plex team to comment on this as I literally cannot see any other reason.

Everyone submit a request here. The more requests sent, the more likely TrueHD will be implemented.
Is it possible to request Plex to transcode True HD to EAC3 Atmos for Apple TV Plex users? That would solve the problem. If it is, where can I officially put in a feature request?

I have posted a feature request to resolve this issue. It would be great if you could vote on it so we can get some attention to it.
Nope, that’s not possible at the moment. There are sadly no tools right now that can transcode TrueHD Atmos to DD+ Atmos.
I’d be happy enough if the Plex app could just output EAC3-5.1 with Atmos to begin with.
Nobody can do TrueHD Atmos out from AppleTV, Apple hasn’t made the software that would allow it. Raise your concern with Apple.
ATV can’t even ouput DD, DTS, etc from AppleTV. ATV in general only outputs LPCM. Which is fine, something was going to convert it, if not the AppleTV then your receiver shrug.
Since it’s a streaming box, Apple has the choice to only enable Atmos support via the lower bitrate DDp. It’s not a special Amazon/Netflix API… because Infuse can do DDp+Atmos on the AppleTV.
The ATV can definitely output DD. (I can’t speak to DD+Atmos overlay or DTS.)
My ATV 4K is set to “Dolby Digital 5.1” output via HDMI.
I’ve got a video with AAC 5.1 direct playing to Plex on the ATV.
The TV shows DD being received.
The soundbar (HDMI ARC) shows DD being received.
You have the AppleTV configured to re-encode the LPCM (in this case decoded AAC5.1) back to DD5.1…why???
If you’re addressing me - perhaps it’s a difference in wiring.
PMS is sending the source AAC 5.1 to the ATV.
The ATV is converting and sending DD 5.1 to the TV.
The TV is passing DD5.1 to the soundbar over ARC.
The soundbar is decoding the DD 5.1 and playing it.
This is pretty much ideal for anybody using ARC, because ARC cannot carry LPCM 5.1. Forcing LPCM at any step would also mean stereo.
If the ATV was plugged into a receiver and ARC wasn’t involved, I’d likely prefer LPCM.
My original point was to correct the statement that the ATV won’t output DD. That is incorrect. The ATV (4K, anyway) can both pass through AND convert to DD 5.1.
Ahhh…you are using ARC. No choice but to go through another round of loss encoding. Other than that all your other points are correct.

Right.
I’m unworried about playback-time conversion for 95% of movie and tv media. Having fewer remote controls means more to me than knowing it was transcoded. It’s a living room, not a theater.
And I’ve got the disks and raw rips for the other 5% of movies, and for the future. But I also stopped worrying as much about “archival” quality movie storage when DVD became Blu-Ray and then UHD and soon enough 8K. For most movies worth keeping, the “new” media will be significantly higher quality.

I strongly suspect that “Auto” is the best audio choice on an Apple TV when a receiver is directly connected - allow the receiver to decode everything possible; let the ATV decode to LPCM for stuff like AAC where the receiver is unlikely to handle it.
I think the hardware is capable of decoding TrueHD if Apple chooses to enable it in tvOS. Feel free to send them feedback; the squeaky wheel gets the grease. https://www.apple.com/feedback/appletv.html
I hope this is the best topic to post this in… I am trying to get EAC3 Atmos to play on my Apple TV which is plugged directly into an Atmos capable soundbar which is then plugged into my TV, I am only getting PCM audio according to the soundbar, I have tried both the Dolby Atmos trailers on Plex and Infuse and still no luck, am I doing something wrong?
I have the same setup as Craigyy92.
Although, based on the discussion above I still don’t fully understand what is happening
I have an EAC3 Atmos demo file from Dolby that plays Atmos succesfully from my ATV with Infuse. But when I play the exact same file via Plex on ATV, there is no Atmos.
Is this really only a licensing thing in Plex? And if yes, why can’t Plex license this and Infuse can?
Or is there still something I am missing?
For those interested: the file I am using is Core Universe that can be downloaded here: https://thedigitaltheater.com/dolby-trailers/
