It requires 100ms because the encoder needs to wait for roughly 100ms
of audio before it can even begin working.  The vorbis encoder
requires a long look-ahead and is not designed for low-latency work.
The encoder is not busy, it is waiting for enough input to proceed;
the output will always lag the input by about 100ms.

If you need lower latency, you will need to use a codec designed for
low-latency operation such as CELT.
