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.
