It is valid, but the data won't be freed this way.  For that to happen,
you'd also need to assign GST_BUFFER_MALLOCDATA(buf), but that assumes
your data was allocated via g_malloc() and friends.  In order to use a
custom free function you'd need to implement your own GstBuffer subclass
(see gstfilesrc.c in core or efence.c in gst-plugins-good for an
example).
