ATTN Adobe: iOS echo cancellation and h264 now easy with iOS SDK

[dqh360]

Hi Adobe,

Based on the iOS SDK documentation, it should now be easy to implement native device echo cancellation on iOS. This feature would be an extremely welcome addition for those of us who have persisted with the Adobe Media Server stack

Using Specific Audio Units

In addition, it's now possible to obtain hardware encoded h264 frames in real time (directly, without streaming to a file and parsing it in real time).

Please can the live streaming system get a little bit of attention?

Cheers.

It's very interesting feature. @chris.campbell What are you think about it?

[chris.campbell]

This is interesting and something I'll share with the team.  We use a third party library for out Runtime targets (desktop FP and AIR) so I'm not sure how easy this would be to plug in, but we'll see what they say.

Many thanks for your attention Chris.

The Android AEC documentation looks promising and straightforward:

As a fallback, given the CPU developments in mobile devices over the last few years I think that the Speex software AEC library would now be viable on mobile, It worked for me on a Windows VoIP client I built about 10 years ago, just need to force the OS run the microphone and speaker at a synchronised sample rate (Windows very much approximated lower sample rates back then)
