PROGRAM:

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
