These are convenience macros for use with the opus_encode_ctl interface.

These are convenience macros for use with the opus_encode_ctl interface.

They are used to generate the appropriate series of arguments for that call, passing the correct type, size and so on as expected for each particular request.

Some usage examples:

int ret;
ret = opus_encoder_ctl(enc_ctx, OPUS_SET_BANDWIDTH(OPUS_AUTO));
if (ret != OPUS_OK) return ret;
 
opus_int32 rate;
opus_encoder_ctl(enc_ctx, OPUS_GET_BANDWIDTH(&rate));
 
opus_encoder_ctl(enc_ctx, OPUS_RESET_STATE);
