SYNOPSIS

11       opusinfo [ -q | -v ] [ -h ] [ -V ] file1.opus ...  fileN.opus

DESCRIPTION

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
20       For  all stream types opusinfo will print the filename being processed,
21       the stream serial numbers, and various common error conditions.
22
23       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
28       Opusinfo  is  a  fork  of  ogginfo(1)  with  the non-opus parts largely
29       removed.

OPTIONS

33       -h     Show a help and usage message.
34
35       -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
39       -v     Verbose mode. At the current time, this does not do anything.
40
41       -V     Show program version info and exit.

NOTES

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.
