RTSP to ROS streaming is not working in container #8

Closed rgov closed 1 year ago

This is after I installed GStreamer packages into the container, or else it didn't know how to open an rtsp URL

I was able to get it to work with the CAM220IP RTSP URL rtsp://admin:1234@192.168.13.30/h264 which is undocumented in the product manual, and when multiple customers asked Raymarine directly about this they didn't just post the information where it could be found with search engines later.
