oggz-diff — Hexdump the packets of two Ogg files and output differences

oggz-diff [options] [OGGZDUMP_OPTIONS] [DIFF_OPTIONS] file1.ogg file2.ogg
options: [--verbose ] [-v | --version ] [-h | --help ]
OGGZDUMP_OPTIONS: [-b | --binary ] [-x | --hexadecimal ] [-c content-type | --content-type content-type ] [-s serialno | --serialno serialno ] [-O | --hide-offset ] [-S | --hide-serialno ] [-G | --hide-granulepos ] [-P | --hide-packetno ]
DIFF_OPTIONS: [-q | --brief ] [-C NUM | --context[=NUM] ] [-u | -U NUM | --unified[=NUM] ] [-e | --ed ] [--normal ] [--rcs ] [-y | --side-by-side ] [-l | --paginate ]

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.

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

-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.

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.

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