Description

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.

Options

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

oggz-dump format options

-b, --binary
Generate a binary dump of each packet

-x, --hexadeciaml
Generate a hexadecimal dump of each packet

oggz-dump filtering options

-c content-type, --content-type content-type
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.

-s serialno, --serialno serialno
Dump only the logical bitstream with specified serialno.

-O, --hide-offset
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.

-S, --hide-serialno
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.

-G, --hide-granulepos
Hide the granulepos field of the preamble for each packet dumped.

-P, --hide-packetno
Hide the packetno field of the preamble for each packet dumped.

diff options

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

-q, --brief
Output only whether files differ.

-C NUM, --context[=NUM]
Output NUM lines of copied context.

-u, -U NUM, --unified[=NUM]
Output NUM (default 3) lines of unified context.

-e, --ed
Output an ed script.

--normal
Output a normal diff.

--rcs
Output an RCS format diff.

-y, --side-by-side
Output in two columns.

-l, --paginate
Pass the output through pr to paginate it.

Miscellaneous options

--verbose
Display verbose messages.
-v, --version
Display version information and exit.
-h, --help
Display usage information and exit.
