Hi,

I have setup an application which receives an RTP stream and streams it out to my multicast network (239.0.0.5, 1234). I am trying to receive the multicast stream thru vlc. The problem is that the stream I receive is garbled and all greyish. This is happening to all my vlc clients. When I monitor the application statistics, I see that the input is 2 Mbps and out is 250Kbps. When I watch the same stream thru wowza test client (adobe RTMP) it plays perfectly fine.

How to solve this problem. Please help. Thanks in advance.

Regards

Sateesh.

Hello,

Do you see this same issue with a different encoding source, such as Wirecast?

Is this stream being transcoded? If not, I would suggest [enabling the transcoder](https://www.wowza.com/docs/how-to-set-up-and-run-wowza-transcoder-for-live-streaming) using the default template transrate and see if the transcoded renditions look different.

Best regards,

Andrew
