file1.opus ... fileN.opus
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.
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.
- Show a help and usage message.
- Quiet mode. This may be specified multiple times. Doing so once will
remove the detailed informative messages; twice will remove warnings as
- Verbose mode. At the current time, this does not do anything.
- Show program version info and exit.
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.
