Re: [Sursound] [Proposal] for HOA web-streaming-format

2023-05-09 Thread Fersch, Christof
Right on the original question and I don’t want to argue either. Just had a 
small investigation recently and learned myself it is not an easy to answer 
question.

For instance, on mobile platforms, e.g., iOS, the underlying framework is the 
same for all browsers and there for codec support is (more or less) independent 
on the browser.

On PC-platforms, Firefox and Chromium-based seems to have a policy not to 
access OS-functionality for media codecs (with exception for some video codecs).

In summary: it is a mess and very dependent on many factors.

Very widely supported is the AAC-family, including LC, HE-AACv1 and v2 
(hopefully soon xHE-AAC also).

Cristof, I actually agree with you, but:

The original question was if Safari supports DD+, “probably”.

See also the subject.

So Safari does, Edge does on Windows, Chrome probably not.

We were “checking” standard browsers.

It is next to obvious that you would use DD+ either for surround sound
(but AAC codecs and open codecs can do the same, of course), or
especially to code Atmos via JOC.

Hope my comments help, as well...

There is not much to “argue”, because I took a neutral position.

Hi guys,



 Thanks for the investigation!



 “Android does not support Dolby codecs.”

 It is true that Dolby codecs are not part of the AOSP codebase.  
However, if Android-based phones support Dolby codecs or not is a  
different story. For instance, I would assume (but cannot check)  
that most Android-based Samsung phones support many Dolby codecs.

 I think that mobile Safari (so the Safari version for iOS and

 iPadOS) should also support DD+ (since iOS 14/iPadOS 14 probably),

 because Apple Spatial Audio supports DD+/Atmos.



 I will try to test this. ;-)



 Otherwise, agreed.
