NAME

       opusinfo - gives information about Opus files and does extensive validity checking

SYNOPSIS

       opusinfo [ -q | -v ] [ -h ] [ -V ] file1.opus ...  fileN.opus

DESCRIPTION

       opusinfo  reads  one  or  more  Opus  files  and  prints information about stream contents
       (including chained and/or multiplexed streams) to standard output. It will detect (but not
       correct) a wide range of common defects, with many additional checks specifically for Opus
       streams.

       For all stream types opusinfo will print the filename being processed, the  stream  serial
       numbers, and various common error conditions.

       For  Opus streams, information including the version used for encoding, number of channels
       and other header information, the bitrate and playback length, the contents of the comment
       header, and general statistics about the stream are printed.

       Opusinfo is a fork of ogginfo(1) with the non-opus parts largely removed.

OPTIONS

       -h     Show a help and usage message.

       -q     Quiet  mode.  This  may  be specified multiple times. Doing so once will remove the
              detailed informative messages; twice will remove warnings as well.

       -v     Verbose mode. At the current time, this does not do anything.

       -V     Show program version info and exit.

NOTES

       There are many kinds of  errored,  invalid,  non-normative,  or  otherwise  unwise  stream
       constructions  which  opusinfo  will not produce warnings on. Passing opusinfo with flying
       colors is not certification of the correctness of a stream.  Future  versions  may  detect
       more error conditions.
