I am not Josh, but this looks straightforward.>From http://flac.sourceforge.net/ogg_mapping.html:
Version 1.0 of the FLAC-to-Ogg mapping
then is a simple identifying header followed by
pure native FLAC data, as follows:
* The first packet of a stream consists of:
o The one-byte packet type 0x7F
o The four-byte ASCII signature "FLAC",
i.e. 0x46, 0x4C, 0x41, 0x43
As 0x7F = \177, yes this is right.
