Attempting to stream ip cameras with rtsp/udp, no publish to topic #67

I am attempting to stream IP camera using RTSP into ROS and I am having trouble configuring the gstreamer parameters correctly. Here is the configuration I am currently using. Running gscam with the below configuration appears to run correctly, but does not output on any topic. I've checked the feed using Wireshark and packets are being received so I believe the issue lies with the sink into a ros-topic. Any fixes or tips for debugging would be great.

GSCAM_CONFIG:

"rtspsrc location=rtsp://admin:admin@10.201.41.102:5541 ! videoconvert"

Node Output:

export GSCAM_CONFIG="rtspsrc location=rtsp://admin:admin@10.201.41.102:5541 ! videoconvert"
