Adobe just released AIR 2.6 SDK, which seems to support cameras and microphone on the iOS devices.
On iOS devices with a both a front- and a rear-facing camera, you can only capture
video from one camera at a time. On Android devices, you can only access the rear-facing camera.
Too bad, they didn't update it for Android to access multiple cameras. I will look into porting ReelPortal to iPhone/iPad now.
Update: Not owning any Apple devices (iphone/ipad/mac), this task may not be as easy as I thought. I'd need to find someone with the devices to help test. Any volunteers?
Update: (June 4 2011) First beta available for testers. A few things are not working yet (text chat), but video/audio are streaming okay. Both front and back camera work!
Update: (July 18 2011) Version 1.0.0 for iOS has been submitted into the App Store, waiting for approval. Text chat is supported. Performance seems a little sluggish compare to Playbook and Android. I wonder if it's due to the single core CPU, or the Adobe iOS packager, or both.
Update: (July 23 2011) See this new post.
