hi,


I'm writing a pipeline with dynamic branch. While removing the branch, I ran into the case in which a queue element will be gst_bin_removed in the probe callback to the queue's peering tee element. My question is, what if there's frame data still hanging in the queue element? Will this lead to a memory leak?

It's a requirement to set the element to NULL state before you unref it. The buffers will be discarded and returned to their appropriate pool and/or allocator during this state transition.


Please share your expertise.


Thanks,

Xin
