Hi All,
  I am trying to display a live stream from rtmp server. Below is my code.

When I try to run this, I could successfully connect to server but not getting the data. If I open the url in browser PublishNotify gets dispatched and I get the stream. As soon as I close UnpublishNotify gets dispatched and I wont get the stream. Can I know the possible reasons and solution?

Answer 1

Unless I am mistaken here, you must implement Apple's HTTP Live protocol for streams over ten minutes in length. There is a few options you can take:
1. Split your streams into 9 minute segments and feed them consecutively in groups. (Apple actually offers a segmenting tool that even generates an index file via there Developer tools)
2. Only enable full length streaming over WiFi
3. Fully implement HTTP Live....
Also, do not forgot that not only are you going to have to implement HTTP Live but you are going to have to ALSO include an audio only stream.
