I try test speex in windows.When I try decode a test frames of data encoded by
speexenc.exe app.The defrence is the decoded data by speexdec.exe is not same by
my app.Here is my test code:what errors I made? Thank you! (My app user
speex-1.2beta1 library) int frame_size;
int nbBytes=0;
int lookahead; int sampleRate=8000;
SpeexBits bits;
void *dec_state;
bEnhance=1;
float output[2000];
char intput[] {
0X2f ,0x87 ,0xa2 ,0xee ,0x4f ,0x42 ,0x7c ,0x7f ,0xff ,0xff ,0xff ,0xff
,0xff ,0x8c ,0x12 ,0x3f ,0xfd ,0x3f ,0xff

};
dec_state = speex_decoder_init(&speex_nb_mode);
speex_decoder_ctl(dec_state, SPEEX_SET_ENH, &bEnhance);
speex_bits_init(&bits);
speex_decoder_ctl(dec_state, SPEEX_SET_SAMPLING_RATE, &sampleRate);
