The second parameter of avcodec_deocde_audio3() MUST be aligned to 16 bytes due to SSE issue try the following code: DECLARE_ALIGNED(16,uint8_t,audio_buf)[(AVCODEC_MAX_AUDIO_FRAME_SIZE * 3) / 2]; int data_size = sizeof(audio_buf); int len = avcodec_decode_audio3(dec,(int16_t *)audio_buf, &data_size,your_packet); -- ----------------------------------------------------------------------------------------- My key fingerprint: d1:03:f5:32:26:ff:d7:3c:e4:42:e3:51:ec:92:78:b2 _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
