My pipeline is dynamically adding and removing sink pads for a video
compositor during the pipeline is running, the program crashed after running
for hours, gdb info listed here. I want to know if compositor element allows
to change sink pads at any time, and if not what's the right way to do it,
thank you

Program terminated with signal SIGSEGV, Segmentation fault.
