Overview
oggzdiff is a sh script which uses oggzdump to generate hexadecimal packet dumps of each input file, then outputs the difference between these dumps using diff.
Options
oggzdiff forwards a subset of options accepted by oggzdump and diff. See oggzdump(1) and diff(1) for more detail.
oggzdump format options
-
-b, --binary -
Generate a binary dump of each packet
-
-x, --hexadeciaml -
Generate a hexadecimal dump of each packet
oggzdump filtering options
-
-c content-type, --content-type content-type -
Dump only the logical bitstreams for a specific
content-type. The following codec names are currently detected: "cmml", "flac", "theora", "speex", "vorbis"
-
-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
prto paginate it.
Miscellaneous options
-
--verbose -
Display verbose messages.
-
-v, --version -
Display version information and exit.
-
