Please clarify availability of H 264 encoding in AIR for iOS/Android

Hello,

I've written an app to send a live camera stream via RTMP in H 264/Nellymoser from mobile devices.  The app works fine on AIR when tested on my Win7 desktop, but when I publish to AIR 3.2 for Android or AIR for iOS, it seems that the H264VideoStreamSettings are simply ignored and the video ends up in Sorenson.  Is H264 supported for encoding/publishing on AIR for mobile devices?  If not, is this planned for the future?

Thanks!
