Thanks for your Reply.

I designed rtmp video stream from the camera to send Wowza, Wowza to receiving rtsp streaming video.

Before there is a video streaming loading time I want to put in the middle image.

But \<[loop a pre-roll until a live stream starts](https://www.wowza.com/docs/how-to-loop-a-pre-roll-until-a-live-stream-starts-loopuntillive)\> support http only, I have being looking for ways to use sdp file.

Streaming video using rtsp how the middle there?
