Correct.

You speak only the truth.

By the way, the offset parameter should be GST_BUFFER_OFFSET_NONE,
unless you're outputting to filesink, in which case it should be the
offset in the file.  (Yes, this is disgusting.  This could be solved
by "transient" buffers (buffers that can't be held between iterations),
but it may require subtle changes to a few, as yet unknown, elements.)
