opus - May 2015 - encoder configuration

Hi,



How can I force encoder to create stereo?

OPUS_SER_FORCE_CHANNELS only works for mono



How can I force encoder to encode at a specific bandwidth?

OPUS_SER_BANDWIDTH only works for FB (1105), and the encoder

Seems to encode at the input samples rate, no rate conversion is done



Thanks,

Michal

Why do you want to force stereo? The encoder is designed such that if
there aren't enough bits to output stereo with enough quality, it
outputs mono instead (with better quality). Similarly,
OPUS_SET_BANDWIDTH() is used to tell the encoder to never go above a
certain bandwidth (e.g. there's no audio content there), but the encoder
will lower the bandwidth by itself to avoid outputing bad artefacts.
