I have a method in an iOS project that calls avformat_open_input(), it runs very well in the simulator, however, when I try to run it on the device it hangs up and just stays there.

Has anyone seen this before?, Any help would be much appreciated.

    That method establishes a connection to the source via URL, RTSP, RTP, etc, if it’s hanging up:

    1. Make sure that the source is in fact streaming data at that address and port
    2. Make sure that you are connected to the right network if this is a local connection.

    Please let me know how it works out.
