           If the error is like: v4l-camera-source / reason

           Solution: configure camera capabilities                          
           Run the script under utils/gst_capabilities.sh and

           Find a suitable framerate=X/1 (with X being an                   
       integer like 24, 15, etc.)                                           
           Then edit config_maskcam.txt and change the line:                
           camera-framerate=X                                               
           Or configure using --env MASKCAM_CAMERA_FRAMERATE=X              
       (see README)

By any chance, are you running on deepstream-5.1?

[Chockaaa]

yes, I am using deepstream-5.1

[Chockaaa]

currently I am facing this issue after changing to deepstream 5.0

I would check:

1. Are any ports being utilized already?
2. If the Yolo extraction was done correctly, since I ran across an error in building yolo on deepstream-5.1 so had to edit the makefile abit

[Chockaaa]

I managed to use docker instead to run it. I think I might have missed some steps in the manual installation process. Thanks.
