Posted on April 22, 2014 at 16:19Hi all,
I'm trying to use the speex library on a STMF205. I have downloaded the AN2812 and the stsw-stm32017 example.
I have copied code example into my project :
/* Speex encoding initializations */
speex_bits_init(&bits);
enc_state = speex_encoder_init(&speex_nb_mode);
speex_encoder_ctl(enc_state, SPEEX_SET_VBR, &vbr);
speex_encoder_ctl(enc_state, SPEEX_SET_QUALITY,&quality);
speex_encoder_ctl(enc_state, SPEEX_SET_COMPLEXITY, &complexity);
/* speex decoding intilalization */
dec_state = speex_decoder_init(&speex_nb_mode);
speex_decoder_ctl(dec_state, SPEEX_SET_ENH, &enh);
/* Flush all the bits in the struct so we can encode a new frame */
speex_bits_reset(&bits);
/* Encode the frame */
speex_encode_int(enc_state, (spx_int16_t*)IN_Buffer[0], &bits);
/* Copy the bits to an array of char that can be decoded */
speex_bits_write(&bits, (char *)out_bytes, ENCODED_FRAME_SIZE);
/* Copy the encoded data into the bit-stream struct */
speex_bits_read_from(&bits, (char *)out_bytes, ENCODED_FRAME_SIZE);
/* Decode the data */
speex_decode_int(dec_state, &bits, (spx_int16_t*)OUT_Buffer[0]);
The compilation is ok but I have a MemManage_Handler during the encoding.
Do you have anyone an idea ? As anyone already used this library (or another one) on STM32F205.
Thanks for all.
David
