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).
