**oggzdump** \[-h  \| --help \]  \[-v  \| --version \]

## Description

**oggzdump** generates a hexadecimal or binary dump  of packets in an Ogg file, or creates an Ogg file from a hexadecimal  oggzdump file.

## Options

**oggzdump** accepts the following options:

### Dump format options

- \-b, --binary

  Generate a binary dump of each packet

- \-x, --hexadecimal

  Generate a hexadecimal dump of each packet

### Filtering options

- \-n, --new

  Only dump the first packet of each new logical  bitstream found; for correctly formed Ogg files, this dumps  only the beginning-of-stream packets.

- \-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 in  conjunction with  **[oggzdiff(1)](/oggzdiff/1.md)** 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 in  conjunction with  **[oggzdiff(1)](/oggzdiff/1.md)** 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.

### Mode options

- \-r, --revert

  Revert an oggzdump. Generates an Ogg bitstream as prescribed  in the input oggzdump.

-

  The serialno, granulepos and packetno fields of the packet  preambles in the oggzdump, as well as any bos or eos markers  if present, are used to structure the packets into logical  bitstreams. Hence it is advised that the original input  oggzdump not be generated with any hiding filters.

-

  Only the hexadecimal data columns of the input oggzdump are  parsed when generating Ogg packet data; the printable character  representation is ignored.

### Miscellaneous options

- \-o **filename**, --output **filename**

  Write output to the specified  **filename** instead of printing it to  standard output.

- \-h, --help

  Display usage information and exit.

- \-v, --version

  Output version information and exit.
