Did you find a solution to this?

The Error Was In My Pipeline Which Couldn't Be Processed In Gscam

Hi! thanks for replying. I am a beginner in all of this and have never worked with ros before. Could you please tell me in details how to fix the pipeline?

It's Not ROS based Error But Rather Gstreamer Error Make Sure You Don't Have Output at the end of your Pipeline(like udpsink or etc) This Is An Example Gscam that Opens camera located at video1 <env name="GSCAM_CONFIG" value="v4l2src device=/dev/video1 ! ffmpegcolorspace " /> and also make sure You are using plugins from the same version (don't mix 0.1 and 1.0 together)

Thanks, I'll try it. Also, which camera did you use?

With Regards, Aishwarya Sarkar

My set up was rather complex due to my use-case It Was Not A camera. It Was a Stream I got From Wireless Network Which i used to redirect to An /dev/video But The Original Image Came From a Rasicam On A RaspberryPi3.
