I'm using the opus-tools package from the current Debian (it says it is
0.1.2). The output of opusinfo is strange:

$ opusinfo demo01.opus
Processing file "demo01.opus"...

New logical stream (#1, serial: 0000456a): type opus
Encoded with libopus 1.0.1-rc3
User comments section follows...

So it seems the real bitrate is about 12kbit/s but opusinfo says it is

Is this some known error that have already been fixed or did I
misunderstand something?
