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
