I am trying to restream an IP CAM out (sdp) using Wowza. The problem is that audio codec is AMR and video is MPEG4. It didnt worked. But when i enabled transcoder and then i can see the video. But still no audio. Any possible solution?

Hi,

The AMR audio codec is not supported by Wowza.

Please take a look at the [Transcoder addon overview article](https://www.wowza.com/docs/wowza-transcoder) for a list of supported video/audio codecs.
