[Speex-dev] a problem about decode !help me!

[hfbgk]

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
  ,0xff ,0xff ,0xeb ,0x3e ,0xfa ,0x84 ,0x97 ,0x4e ,0x1c ,0x81 ,0x8a ,0xcc ,0xfa ,0x5a ,0xef ,0x07 ,0xbf ,0x9b ,0x67
 };
 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);
 /////////////////////////////////////////
 speex_bits_read_from(&bits, intput, 38);
 ret=speex_decode(dec_state, &bits, output);
 *outputBufSize=frame_size;
