NAME

       ogmdemux - Extract streams from OGG/OGM files into separate files

SYNOPSIS

       ogmdemux [options] inname

DESCRIPTION

       This program extracts all or only some streams from an OGM and writes them to separate files.

       inname Use 'inname' as the source.

       -o, --output out
	      Use  'out'  as  the  base  for  destination  file  names.  '-v1', '-v2', '-a1', '-t1'... will be appended to this name. Default: use
	      'inname'.

       -a, --astream n
	      Extract specified audio stream. Can be used more than once. Default: extract all streams.

       -d, --vstream n
	      Extract specified video stream. Can be used more than once. Default: extract all streams.

       -t, --tstream n
	      Extract specified text stream. Can be used more than once. Default: extract all streams.

       -na, --noaudio
	      Don't extract any audio streams.

       -nv, --novideo
	      Don't extract any video streams.

       -nt, --notext
	      Don't extract any text streams.  Default: extract all streams.

       -r, --raw
	      Extract the raw streams only.  Default: extract to useful formats (AVI, WAV, OGG, SRT...).

       -v, --verbose
	      Increase verbosity.

       -h, --help
	      Show this help.

       -V, --version
	      Show version number.

NOTES

       What works:

       *      Extraction of the following formats is fully supported including writing the stream contents to useful container formats:
		video  -> AVI
		Vorbis -> OGG/Vorbis
		PCM    -> WAV
		text   -> text files (SRT subtitle format)

       *      All other audio streams (MP3, AC3) are just copied 1:1 into output files. MP3 and AC3 files should be usable. Others might not.

       What not works:

       *      Headers created by older OggDS (DirectShow) filter versions are not supported (and probably never will be).

NAME

       ogminfo - Print information about streams in OGG/OGM files

SYNOPSIS

       ogminfo [options] inname

DESCRIPTION

       This program lists all streams contained in an OGM including information about the codecs used.

       inname Use 'inname' as the source.

       -v, --verbose
	      Be verbose and show each OGG packet. See the section 'VERBOSITY LEVELS' for details.

       -s, --summary
	      Will  print  a  short  summary  for each stream including the total size in bytes, the bitrate, the number of packets/frames and the
	      length in seconds. This requires the parsing of the complete file.

       -h, --help
	      Show usage information.

       -V, --version
	      Show version information.

VERBOSITY LEVELS

       The -v option can be used to increase ogminfo's verbosity level and print more information about the current file.

       level 0
	      will print only the streams it finds and their types.

       level 1
	      will also print each stream's header and comment packets' contents.  These two modes will not process the whole file (as opposed	to
	      all other modes) if the comment packets are placed correctly.

       level 2
	      will  print  a  line  for  each OGG packet it encounters containing the stream the packet belongs to, the payload size, the packet's
	      granulepos, the packet's number, its start time, its end time and several flags. The flags may include  'sync_ok'  or  'OUT_OF_SYNC'
	      which  indicates	whether the packet's placement in the file is correct according to its granulepos.  Other flags are 'IS_SYNCPOINT'
	      or 'EOS'.
	      level 2 and above automatically imply --summary.

       level 3
	      also prints a line whenever a new OGG page was read completely along with the page's exact position in the file it was read from.

       level 4
	      will dump the complete stream_header structure found in the header packet for any non-Vorbis stream.

       The levels 3 and 4 are intended for debugging purposes only.

NOTES

       What works:

       *      OGM with Vorbis audio, 'normal' video (like DivX etc.), audio streams (PCM, MP3 etc.), text streams (subtitles).

       What not works:

       *      Headers created by older OggDS (DirectShow) filter versions are not supported (and probably never will be).
