playback doesn't always start after AVPlayer::setTimeRange()

[combiner]

the chances that i will hear the sound when i start the following program are about 50%:

int main(int argc, char **argv) {
    QCoreApplication app(argc, argv);
    QtAV::AVPlayer player;
    player.setFile(argv[1]);
    player.setTimeRange(450, 10000);
    player.play();
    return app.exec();}

here's the audio file i've got problems with:

It's weird. Packet read from demuxer is wrong.
