Hello!
We are testing Wowza because we are interested in the stream re-casting capabilites (StreamType= rtp-live) to allow many users consume the same camera consuming only one stream from it on demand.
In the Wowza server, live application, we create a new Stream, coming from the camera with a rtsp command similar to this: rtsp://cameraIp/. We have tested this rtsp command with VLC in the Wowza server machine and VLC shows no issues.
Then we test VLC to consume the re-stream using rtsp://localhost:1935/live/test.stream and the stream that is shown in VLC takes a lot to load, in plays a few frames and closes after 15 seconds, video come and leave randomly.
hint: this issue happens with the Moxa camera we are testing but works fine with other bosch camera.
What should I change to tune or help wowza re-stream the moxa camera??
Thanks
Hello
Thanks for contacting the Wowza Community
Here is an article on re-streaming a IP camera:
https://www.wowza.com/docs/how-to-re-stream-video-from-an-ip-camera-rtsp-rtp-re-streaming
Make sure that your camera is outputting a format Wowza supports and also the keyframe intervals is between 1-3.

Hope this helps. If any further questions, feel free to reach out

Hi.
We followed some of the tips.
The behaviour improved but we still face some issues.
Bare in mind we need to configure the stream type to StreamType= rtp-live because we want the camera to be consumed in demand.
1 - If we consume the camera using VLC command:
rtsp://wowzaip/live/test.stream
The VLC shows an error at the beginning. Apparently Wowza server has no time enough to start sending the camera stream before the VLC times out in the client.
If we consume the stream from the client using rtmp, the error does not happen.
Is there any way to speed up Wowza when using RTSP?
2- When consuming the stream using
rtmp://wowzaip/live/test.stream
The Vlc shows the video but with a delay of around 10-12 seconds.
Is there any way to configure Wowza for low latency (keeping “rtp-live” configuration)

Finally the main issue was related to the camera not sending audio track.
When that happens Wowza waits that track to times out and the consequence is a long delay to open a a very delayed video stream playback.
The solution that worked for me was to configure the camera to send audio.
The other option regarding configuring the stream file to ignore rtspaudio track did not behave as expected.
