oggz-diff is a sh script which uses oggz-dump to generate hexadecimal packet dumps of each input file, then outputs the difference between these dumps using diff.

oggz-diff forwards a subset of options accepted by oggz-dump and diff. See oggz-dump(1) and diff(1) for more detail.

Generate a binary dump of each packet
Generate a hexadecimal dump of each packet

Dump only the logical bitstreams for a specific content-type. Run oggz-known-codecs(1) for a full list of codecs known by the installed version of oggz.
Dump only the logical bitstream with specified serialno.
Hide the byte offset field of the preamble for each packet dumped. This is particularly useful when comparing Ogg bitstreams that differ only in page structure.
Hide the serialno field of the preamble for each packet dumped. This is particularly useful when comparing Ogg bitstreams that differ only in serialno assignment.
Hide the granulepos field of the preamble for each packet dumped.
Hide the packetno field of the preamble for each packet dumped.

The -w (--ignore-all-space) option to diff is always implied.

Output only whether files differ.
Output NUM lines of copied context.
Output NUM (default 3) lines of unified context.
Output an ed script.
Output a normal diff.
Output an RCS format diff.
Output in two columns.
Pass the output through pr to paginate it.

Display verbose messages.
Display version information and exit.
Display usage information and exit.
