Adds a buffer list to the queue of buffers and buffer lists that the
appsrc element will push to its source pad. This function does not take
ownership of the buffer list so the buffer list needs to be unreffed
after calling this function.
When the block property is TRUE, this function can block until free space
becomes available in the queue.
