    Description

      I tried to use TRY_VERIFY_WITH_TIMEOUT on the tst_QAudioDecoderBackend test, but it freeze the test for a long time.

      Delay with do{} while()

      int times = 0; 
 do

{       QTime dieTime= QTime::currentTime().addMSecs(5);      while (QTime::currentTime() < dieTime)          QCoreApplication::processEvents(QEventLoop::AllEvents, 100);      times++; }

while (recorder.recorderState() == QMediaRecorder::RecordingState && times < 10);

      I think that QTRY_VERIFY_WITH_TIMEOUT works differently with a QThread.

      QAndroidAudioDecoder use a QThread for the Decoder.
