I have been trying to run "rtsp_stream.launch" through roslaunch. I am publishing my mobile camera input to an ip address using http protocol for doing that I just changed the following line
<arg name="video_stream_provider" value="http://192.168.10.9:4747/video" />
But i keep receiving the following errors
