      Description

      call of QAudioDecoder::read() method leads to memory leaks

      I initialize QAudioDecoder* decoder by a way:

      decoder = new QAudioDecoder;
      decoder->setSourceFilename(audioFileName);
      connect(decoder, SIGNAL(bufferReady()), SLOT(processBuffer()));

      and then in a method

      MyClass::processBuffer()

      if i just invoke decoder->read() many times it leads to big memory leaks

      Note: delete of decoder not solve that issue

      ---------
      Is there is a fast way to avoid this problem? Or Is there are another ways to process coded audio files without QAudioDecoder?
