Hi,
I would like to check to send 2 video streams to wowza account using 2 sdp files from the same origin/host.
I would like to know what parameters of the sdp file needs to be changed such that 2 video streams should not mixup/overlap.
Thanks.
Hello @Kiran Patil, I checked for you and you should be able to stream from the same origin/host by using a different port number. Can you try that and let me know? Thanks.
“m=” is used to listen audio and video with the associated ports.
https://tools.ietf.org/html/rfc4566#section-5.14
“a= rtpmap” is used to map different inputs.

FFmpeg can provide an example.
ffmpeg.exe -re -i input.mp4 -vcodec copy -an -f rtp rtp://192.168.1.23:10002 -vn -acodec copy -f rtp rtp://192.168.23.1:10000
This is what it output. I have added a blank line to differentiate between audio and video.
v=0
o=- 0 0 IN IP4 127.0.0.1
s=No Name
t=0 0
a=tool:libavformat 58.9.100
m=video 10002 RTP/AVP 96

Ensure that each SDP file has no overlap for different audio or video streams. Do not create SDP files by hand.
