Question
Speex Library
Posted on April 22, 2014 at 16:19
Hi 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
