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
