Maybe a review of the configuration options would be interesting?
Make all options like
So you would have
e.g. SPEEX_SET_VBR_BITRATE, ...
would also make sense: e.g. set vbr_quality so that the average bitrate
is as specified.
Now it is easy to make a mistake when configuring the encoder (because
now abr/cbr/vbr is sometimes set separately from bitrate/mode/quality).
It would also be nice if there is a intuitive mapping between the RFC
the encoder configuration. Examples:
- how to configure encoder when SDP specifies: b=AS:10 and vbr
- how to configure encoder when SDP specifies: cng
