I have implemented runtime source addition and deletion with deepstream-test5-app similar as CUDA Memory Leak Problem While Runtime Souce Addition/Deletion. The program shows gradually memory leak problem, at speed about 1G/h.
I use the gst-tracer to trace leaked objects. It shows there’re lots of (linear to the number of sources processed) GstCaps objects remains alive after program exits with refcount=1. The trace stack shows it is related to ‘libgstnvvideo4linux2’.
Is there any way to fix it?
