oggz-merge — Merge Ogg files together, interleaving pages in order of  presentation time.


oggz-merge [-o filename  | --output filename ] filename ...  

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


oggz-merge merges Ogg files together, 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.

For example, if you have an Ogg Theora video file, and its soundtrack  stored separately as an Ogg Speex audio file, and you can use  oggz-merge to create a single Ogg file containing  the video and audio, interleaved together in parallel.

Similarly, using oggz-merge on a collection of Ogg  Vorbis audio files will create a big Ogg file with all the songs in  parallel, ie. interleaved for simultaneous playback. Such a file is  proper Ogg, but not "Ogg Vorbis I" -- the Ogg Vorbis I specification  defines an Ogg Vorbis file as an Ogg file containing only one Vorbis  track at a time (ie. no parallel multiplexing). Many music players  (which use libvorbisfile) aren't designed to play multitrack Ogg files.  In general however, video players, and anything built on a multimedia  framework (like GStreamer, DirectShow etc.) will probably be able to  handle such files.

If you want to create a file containing some Ogg files sequenced one  after another, then you should simply concatenate them together using  cat. In Ogg this is called "chaining". If you cat  Ogg Vorbis I audio files together, then the result will also be a  compliant Ogg Vorbis file.


oggz-merge 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.


Merge pages of audio.oga and video.ogv:

oggz merge -o output.ogv audio.oga video.ogv
