Bitrate in encoder
Hi,
I'm using the latest version of libspeex (checked out today) and have
some problems with checking the target bitrate in the encoder. Calling:
peex_encoder_ctl(globals->enc_state,SPEEX_GET_BITRATE, &bitrate);
Seems to set bitrate to 24600 no matter what the qualitysetting is.. The
functions used previous to this call is:
peex_bits_init(&globals->bits);
globals->enc_state = speex_encoder_init(&speex_nb_mode);
speex_encoder_ctl(globals->enc_state,SPEEX_SET_COMPLEXITY,...

I mean that SPEEX_GET_BITRATE will actually return the total bit-rate in
bits per second.
Cheers,

Did you make sure it really *sets* and not just return an incorrect
result?
