NAME

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

SYNOPSIS

       opusinfo [ -q ] [ -v ] [ -h ] 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 stan-
       dard 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.

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 condi-
       tions.
