NAME

       oggz-sort -- Sort the pages of an Ogg file in order of presentation time.

SYNOPSIS

       oggz-sort [-o filename  | --output filename ] filename

       oggz-sort [-h  | --help ]  [-v  | --version ]

Description
       oggz-sort  sorts  an  Ogg file, interleaving pages in order of presentation time.  It correctly interprets the granulepos timestamps of Ogg
       CELT, CMML, Dirac, FLAC, Kate, PCM, Speex, Theora and Vorbis bitstreams.  Run oggz-known-codecs(1) for a full list of codecs known  by  the
       installed version of oggz.

       Some  encoders  produce	files with incorrect page ordering; for example, some audio and video pages may occur out of order. Although these
       files are usually playable, it can be difficult to accurately seek or scrub on them, increasing the likelihood of glitches during playback.
       Players may also need to use more memory in order to buffer the audio and video data for synchronized playback, which can be a problem when
       the files are viewed on low-memory devices.

       Some older Ogg encoders also produce pages which incorrectly have granulepos timestamps recorded that shouldn't be:  pages  which  have	no
       completed packets must have a granulepos of -1.	oggz-sort will correct such granulepos during the process of sorting.

       The  tool  oggz-validate  can be used to check the relative ordering of packets in a file, and also to detect incorrect granulepos on pages
       with no completed packets. If either of these errors are reported, or use oggz-sort to fix the problem.

Options
       oggz-sort accepts the following options:

   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

       Correct the page ordering in broken.ogv:

	      oggz sort -o fixed.ogv broken.ogv

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) 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)
		 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)  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 rep-
		 resentation 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
