When encoding Opus files, Ogg encoders should take into account the
algorithmic delay of the Opus encoder.

In encoders derived from the reference implementation, the number of
samples can be queried with:
-
- opus_encoder_ctl(encoder_state, OPUS_GET_LOOKAHEAD, &samples_delay);

To achieve good quality in the very first samples of a stream, the Ogg encoder
MAY use LPC extrapolation to generate at least 120 extra samples
(extra_samples) at the beginning to avoid the Opus encoder having to encode
