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 informa-
       tion 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' con-
	      tents.  These two	modes will not process the whole file (as  op-
	      posed to all other modes)	if the comment packets are placed cor-
	      rectly.

       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).
