15 opusinfo reads one or more Opus files and prints information about
16 stream contents (including chained and/or multiplexed streams) to stan‐
17 dard output. It will detect (but not correct) a wide range of common
18 defects, with many additional checks specifically for Opus streams.
19 For all stream types opusinfo will print the filename being processed,
21 the stream serial numbers, and various common error conditions.
22 For Opus streams, information including the version used for encoding,
24 number of channels and other header information, the bitrate and play‐
25 back length, the contents of the comment header, and general statistics
26 about the stream are printed.
27 Opusinfo is a fork of ogginfo(1) with the non-opus parts largely
29 removed.

33 -h Show a help and usage message.
34 -q Quiet mode. This may be specified multiple times. Doing so once
36 will remove the detailed informative messages; twice will remove
37 warnings as well.
38 -v Verbose mode. At the current time, this does not do anything.
40 -V Show program version info and exit.
42
45 There are many kinds of errored, invalid, non-normative, or otherwise
46 unwise stream constructions which opusinfo will not produce warnings
47 on. Passing opusinfo with flying colors is not certification of the
48 correctness of a stream. Future versions may detect more error condi‐
49 tions.
