• Looking for technical details about X265 encoding and decoding

  10 décembre 2015, par Sitoumbaz

  I’am working on x265, Is there some one who can you share with me how did I encode yuv using x265 codec ? I Need to know how do you get pixel encoded from picture_out structure, And can you tell me if this code is good ? Hope get solution from you ! I’am using the x265 api documentation but it is less understandable.

  ret = x265_encoder_encode(encoder, pp_nal, &pi_nal, pic_in, pic_out);
  
  if(ret < 0){
  
  
  
      printf("encodePictureIn, Error in x265_encoder_encode %d\n",ret);
  
      return ret; 
  
  }
  
  
  
  do{
  
  
  
      ret = x265_encoder_encode(encoder, pp_nal, &pi_nal, NULL, pic_out);
  
      printf("...\n");
  
  
  
  }while(ret > 0);
