public class BufferList : MiniObject

Buffer lists are an object containing a list of buffers.

Buffer lists are created with BufferList and filled with data using insert.

Buffer lists can be pushed on a srcpad with push_list. This is interesting when multiple buffers need to be pushed in one go because it can reduce the amount of overhead for pushing each buffer individually.
