OPUS EXAMPLE

[nimaltd]

i have compiled opus lib on H5. but i can not decode data.

this is my init function and works fine.  

  DecConfigOpus.channels = 2;
  DecConfigOpus.ms_frame = 20;
  DecConfigOpus.sample_freq = 48000;
  uint32_t dec_size = DEC_Opus_getMemorySize(&DecConfigOpus);
  DecConfigOpus.pInternalMemory = (uint8_t *)malloc(dec_size);
  int opus_err;
  if (DEC_Opus_Init(&DecConfigOpus, &opus_err) != OPUS_SUCCESS)
  {
       printf("ERROR! DEC_Opus_Init()\r\n");
      break;
  }

and in decode function first time return 960 and then -4.

int packetSize = 80; // Adjust based on your actual packet size
for (int i = 0; i < sizeof(music); i += packetSize)
{
    int x = DEC_Opus_Decode((uint8_t*)&music[i], packetSize, DecConfigOpus.pInternalMemory);
    if (x < 0)
    {
          printf("Error decoding packet at index %d: %d\n", i, x);
         break; // Exit the loop or handle error as appropriate
    }
    else 
    {
       printf("Decoded packet at index %d, x = %d\n", i, x);
    }
}

Hello @nimaltd ,

A gentle reminder on how to post a thread in this community mainly on how to share a code source. I suggest to review these recommendations.

Thank your for your understanding.

i think i found the problem, my start point of data was wrong. ( skip header/tag did not work property)

how to find the packetSize?
