I have a custom hardware device that is serving up 3 live streams. 1 audio stream (a) and 2 video streams (I'll label b and c ). We are currently using SDP files to create 2 RTMP streams for our playback environment. The first sdp file contains the audio stream (a) and the first video stream (b). The second sdp file contains only the second video stream (c) and no audio.
I have new playback requirements to support two more RTMP streams. An audio only stream (a) as well as a combination of the audio (a) and the second video stream (c)
Is there any way to do this without having to open up more ports on my custom hardware device and duplicating the rtp streams?
