No audio in WebRTC Stream (AAC -> Opus transcoding)

[jyotiprajapati98]

I have transcoded the Opus stream to play the WebRTC live stream, but when I run the streamer, I am getting this error:

./webrtc-streamer -a -v -n wireless -u rtsp://localhost:8554/transcoded_stream

Hi @jyotiprajapati98

For audio you need to define an url for audio, not only for video.
