Description

I was trying to use RTSP stream from ZED X Camera, but I encountered error following this manual: GStreamer - ZED RTSP Server.

Steps to Reproduce

1. gst-zed-rtsp-launch zedsrc ! videoconvert ! 'video/x-raw, format=(string)I420' ! x264enc ! rtph264pay pt=96 name=pay0
2. gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:8554/zed-stream latency=0 ! decodebin ! fpsdisplaysink

Expected Result

I expected RTSP stream to be displayed on the client side.

Actual Result

Error on client's side:

Hi @jkaniuka
Connecting to rtsp://:8554/zed-stream
did you set a value for ${SERVER_IP}?
You must use the IP of the camera that is streaming

[jkaniuka]

@Myzhar Yes, I changed it to 127.0.0.1 😉

[jkaniuka]

Hi @Myzhar, I've updated my issue. Now there's also an error on server's side 😞

[Myzhar]

Are you using Docker?
If that's the case then the warning
[ZED-X][Warning] Failed to connect to zed_x_daemon.
is expected and you can ignore it. The zed_x_daemon runs on the host side.

[jkaniuka]

I realized that I had another stream running in the background and that probably caused [ZED-X][Warning] Failed to connect to zed_x_daemon. error. I checked once again and now there's only an error on client's side. I've updated the issue.
