# oggz-dump(1)

Hexdump packets of an Ogg file, or revert an Ogg file from such a hexdump

## NAME

oggz-dump — Hexdump packets of an Ogg file, or revert an Ogg file from  such a hexdump

## SYNOPSIS

**oggz-dump** \[-b  \| --binary \]  \[-x  \| --hexadecimal \]  \[-n  \| --new \]  \[-o **filename**  \| --output **filename** \]  \[-c **content-type**  \| --content-type **content-type** \]  \[-s **serialno**  \| --serialno **serialno** \]  \[-O  \| --hide-offset \]  \[-S  \| --hide-serialno \]  \[-G  \| --hide-granulepos \]  \[-P  \| --hide-packetno \] filename

**oggz-dump** \[-r  \| --revert \]  \[-o **filename**  \| --output **filename** \] filename

**oggz-dump** \[-h  \| --help \]  \[-v  \| --version \]

## Description

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

## Options

**oggz-dump** 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**. Run **[oggz-known-codecs(1)](/oggz-known-codecs/1.md)** 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 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 oggz-dump. Generates an Ogg bitstream as prescribed  in the input oggz-dump.

-

  The serialno, granulepos and packetno fields of the packet  preambles in the oggz-dump, 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  oggz-dump not be generated with any hiding filters.

-

  Only the hexadecimal data columns of the input oggz-dump 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.

## EXAMPLES

Dump all bitstreams in file.ogg:

`oggz dump file.ogg`

Dump only the Theora bitstream in file.ogv:

`oggz dump -c theora file.ogv`
