/**
 * Buffer lists are an object containing a list of buffers.
 *
 * Buffer lists are created with gst_buffer_list_new() and filled with data
 * using a gst_buffer_list_insert().
 *
 * Buffer lists can be pushed on a srcpad with gst_pad_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.
