Yes you can, but there are a lot of caveats. Here are few:

- the camera does not change orientation when the device's orientation changes

- hardware accelerated video rendering is hit or miss on Android

- hardware accelerated video decoding of RTMP streams is not possible on iOS

- StageVideo is limited to one instance on iOS and Android

- Acoustic Echo Cancelation is not supported on iOS and Android

Note that that article might lead you to believe that it is possible to use H.264 for your live RTMP video streams, but it won't work because H.264 RTMP streams will not play on iOS. You'll hear the audio but see no video. You can use the livepackager Flash Media Server app to repackage a RTMP stream as a HTTP Live Streaming H.264 stream, but the latency is unbearable (8+ seconds).

Although it is mentioned in FMS FAQ's that communication application can be built on ios but

I was unable to find any sample online that is the reason why i was suspisious.

I have read somewhare that in ios you cannot use rtmp protocol for live stream input.

So will user publish stream in rtmp and view other user through hls on ios?

Can you point out the android application you mentioned?
