Hi

I found memory leak using decodeToFd blew.

while(1) {
          ret = ctx.jpegdec->decodeToFd(fd, ctx.in_buffer, ctx.in_file_size, pixfmt,
          width, height);
          g_renderer->render(fd);
          //      cout << "test " << endl;
        }

Please check the attached file and excute blew

./jpeg_decode  num_files 1 baboon.jpg out.raw --decode-fd

Hi,
You still need the prebuilt lib on r32.2.3. Please replace it and give it a try.
