{{{
cigaes at hellroy /tmp $ oggenc -b 128 12345.wav
Opening with wav module: WAV file reader
Encoding "12345.wav" to
"12345.ogg"
at approximate bitrate 128 kbps (VBR encoding enabled)
Mode initialisation failed: invalid parameters for bitrate
zsh: exit 1 oggenc -b 128 12345.wav
}}}
It works with {{{-b 64}}}: apparently it is a libvorbis limitation, that
was brought into evidence when the default bitrate was changed from 64k
(quite awful with real audio) to 128k.
And it has nothing to do with the sample rate being odd, just it being to
low.
Why would you use fixed bitrate anyway?
OTOH, error reporting from libvorbis is not good at all.
