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).
