Error streaming rtsp camera with video_stream_opencv

edit

I am trying to stream an ip camera over rtsp using video_stream_opencv. I have been able to successfully visualize the camera using VLC with the command:

vlc --network-caching=500 rtsp://admin:admin@10.201.41.101:5541

However any attempts to stream the camera with opencv or video_stream has failed. Here is the result of attempting to run video_stream_opencv:

roslaunch video_stream_opencv camera.launch video_stream_provider:="rtsp://admin:admin@10.201.41.101:5541" visualize:=true
