Currently experimenting with trial license and trying to LIVE stream H264 video with uLAW audio . I could able to stream video with audio using local rtsp url using VLC player. But when push this local rtsp stream to Wowza server, i am not able to get audio while streaming using Wowza rtsp url. Please find the ffmpeg console print shown below, where i could see that the audio is being pushed to Wowza local server.

Guessed Channel Layout for Input Stream #0.1 : mono

I have of course configured to use the transcoder, but with no success. I have gone through this

[https://www.wowza.com/docs/wowza-transcoder](https://www.wowza.com/docs/wowza-transcoder) wowza help url, but i couldn’t resolve my issue. I could able get video stream without fail.

please note i was able to play video with audio ( format PCM mulaw format,

Stream #0:1: Audio: pcm\_mulaw, 8000 Hz, mono, s16, 64 kb/s )

Any help or suggestions would be appreciated.
