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.
