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).
