Comment:

 The problem is that libopus only accepts the following sample rates: 8kHz,
 12kHz, 16kHz, 24kHz and 48kHz. These are all saved in the output file and
 are shown by opusinfo. Other sample rates (like 44100Hz) cannot be used to
 encode (libopus returns an error) and are (therefore) not saved in the
 file.
 I don't see how this could be fixed within FFmpeg and will close this
 ticket.
