Explaining Gstreamer plugin example

[horai]

That was a backtrace in case of creating 4 pipelines again and running them
via GST_STATE_PLAYING (after leaving single camera view)
Sometimes I also experience backtrace when going from 4 camera view mode to
single camera fullscreen mode this backtrace:
malloc_consolidate(): invalid chunk size

Thread 257 "GstWlDisplay" received signal SIGSEGV, Segmentation fault.

If you have any clue, please let me know as I am totally lost
