Description
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 pr to paginate it.
Miscellaneous options
- --verbose
-
Display verbose messages.
- -v, --version
-
Display version information and exit.
- -h, --help
