Atmos

[jeremy1234]

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!

Got it I'll have to put on the hipboots and wade into ffmpeg to see why eac3/atmos is not getting detected for this one.

Great! So its not just me , 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.

Any update on why this file didnt work?

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?
