--- Comment #10 from Greg Rutz <g.rutz at cablelabs.com> ---
The current implementation of GST_FOURCC_ARGS() macro expects the fourcc data
to be a guint32 in LE format.  Looks to me like there is one of two problems:

1) GST_FOURCC_ARGS macro that is used in the offending debug statement is wrong
and should be expecting a BE guint32.  I am doubtful that this is the case,
since I'm sure this macro is used in other places.

2) GST_FOURCC_ARGS is correct and the guint32 aux_info_type should be read as
LE using gst_byte_reader_get_uint32_le()
