Question that I’m sure has been beaten to death but just for my own clarification, my receiver still is saying multi-in with Atmos movies. I really don’t care about the display on the receiver but are all channels being separated the same as bitstream would be doing? I don’t really want to buy a shield just for bitstream...

Thanks!

So isn't ffmpeg demuxing on Shield as well? Why does it work on that platform but not tvOS? :?

Because proper passthrough is not supported under tvOS. With eac3/atmos, the atmos is transparent to the eac3 part and carried along. It magically gets to the a/v receiver. With tvOS, it's a different story.

Perhaps you know already but the example cited in this thread and some other files have dropped in the last few days that are from a "new" source. It starts with an i and ends with Tunes. DRM broken. That's why we're seeing different behavior in the Atmos handling I'd imagine.

Block size is different than the others. EAC3/Atmos handling is being refactored to be more robust.

Good to hear :)

When the refactor is succesful, will we see it in 3.8.1 or so?
