Hi Andrew,

The stream is not empty because is plays correctly on the player.

I use the methods bellow in a loop to add the content to the stream, just like in ModuleAddAudioTrack:

this.publisher.addAudioData(APacket.getData(), APacket.getData().length, APacket.getAbsTimecode() + offsetTimeCode);

…

this.publisher.addVideoData(VPacket.getData(), VPacket.getData().length, VPacket.getAbsTimecode());

I added the following statement in onConnect method of Module and it is not firing MediaCaster anymore.

client.setStreamType(“live”);

The following post was very helpfull to get closer to understand what is going on.

Over a year ago I set up a test using RTPLIVE – basically, just to webcast a small music festival. It worked and I’ve continued using RTPLIVE from that point forward. But, I was reading through some of the documentation one day and saw that it recommended that I stream through LIVE for the type of streaming I …

I would like to know if it is the correct approach.

I would like to known too if it is possible to set it on stream basis and not on client connection basis as I did. To avoid it affect all stream in client connection.

Thanks.

Aloha,
