Hi

Did you follow the guide here,

https://www.wowza.com/docs/how-to-set-up-live-streaming-using-a-native-rtp-encoder-with-sdp-file

Be sure that you have removed the .txt extension off the name of your .sdp file sometimes its forgotten and it doesn’t work if you have myStream.sdp.txt.

Hi

Have you set the stream type to “live” as shown in the tutorial? :

live

What ever is sending the stream to Wowza is the encoder which i think is your imx53 qsb board.

The stream name is what ever is being sent by this encoder which in the logs appears to be “video0”.

Your encoder will create the .sdp file and you will have to look up examples of .sdp files on the internet to familiarize yourself with what is required inside the file as this varies considerably for different encoders.
