I use nvcompositor to composite RTSP videos and process them with deepstream.
However, executing the following pipeline results in a segmentation fault.
The following pipeline is a simplified version of the pipeline that causes a segmentation fault.
Adding caps with width and height set to the nvcompositor source pad prevents segmentation faults.
Does nvcompositor require caps with width and height set to be added to the source pad?
Or is there another way to prevent a correct segmentation fault?
I run this command in the docker container.
