Thanks for you comment, we have used the PushPublish add on,
the problem is you can push a video with a name v1 ( with sdp description ), and two
two audio’s with names a1 and a2 separately, but how to playback it on the edge server with v1/a1 and v1/a2
as combined streams. ( this works if from the encoders send the separate video and audio streams to wowza origin, with
udp port sharing possiblities ).
Salvadore is correct in the traditional method of origin/edge, this is done using WOWZ or RTMP protocol.
However you could try using the PushPublish feature which supports the pushing of streams using MPEG-2 Transport Stream (MPEG-TS).
Please find the article for PushPublishing below if this is something you wish to use.
For a audio only or video only version of the stream, you can use the transcoder to create a new stream and disable the audio or video.
The name of the streams then coming out of the transcoder must match the stream names in the PushPublishMap.txt file.
You can test the output using VLC player.
Note the @ in the URL which is required with VLC player for playback using UDP.
