This small article will demonstrate an easy way to remove audio (or video) from an rtmp playback stream. Simply implement the IMediaStreamActionNotify3 interface and set the receive audio/video to false within the event handler as follows:
public class StripAVFromRTMPModule extends ModuleBase {
public void onStreamCreate(IMediaStream stream)
{
stream.setReceiveAudio(false);
stream.setReceiveVideo(true);
}
public void onStreamDestroy(IMediaStream stream)
{ }
}
