retransmitting stream from camera

Wowza Streaming Engine
1

HI,

I’ve configured the server following this instruction:

Re-streaming an RTSP stream through Wowza Pro (RTSP/RTP))

After entering correct informations and clicking play button on /examples/LiveVideoStreaming/client/live.html I’m getting the blank/black video stream.

This camera supports only RTP over UDP

There is some error on the server side:

"DEBUG server comment - status: 400

DEBUG server comment - response: Bad"

What is causing this problem, please help :slight_smile:

This is full log from the server:

"DEBUG server comment - DESCRIBE: SDP: trackCount:1 trackNames:[track1,header]

There is an example in each of these posts of transcoding the video in an RTSP stream to h.264 for Wowza re-streaming:

HI,

Thank you for the replay. This camera does not support H.264 and its why I can not go by this steps.

I’v tested the camera with ffmpeg and downloading the stream is possible.

Do you have other idea how to solve the problem?

Maybe the problem is that the camera is RTP over UDP while the “Transport” in the server is TCP

Transport: RTP/AVP/TCP;unicast;interleaved=0-1
