Hello,

In my application, I stream from iPhone/ Android camera and play it on various platform. While viewing the stream, it works on certain network and in certain it doesn’t.

For example, I initiated a stream from iPhone and that played well when shared to Android in my office network. But when I switch to cellular, it doesn’t work anymore.

My Wowza is hosted in EC2 and I have all UDP ports opened.

Another thing I noticed is, below example stream plays in all network from my app -

rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny\_115k.mov

Is there any way to get the settings of above example stream? Or a way to find out the problem I am facing?

I am using live555 player in my Android app.
