QtAVPlayer: Unable to play media on Qt6.3

I followed your example code but seems the media won’t start. This is what I made:

QVideoWidget w(baseWidget);
w.show();

QAVPlayer p;
QAVAudioOutput audioOutput;
connect(&p, &QAVPlayer::audioFrame, [&audioOutput](const QAVAudioFrame& frame) {
	qDebug() << "AudioFrame";
	audioOutput.play(frame); 
	});
connect(&p, &QAVPlayer::videoFrame, [&](const QAVVideoFrame& frame) {
	qDebug() << "VideoFrame";
	QVideoFrame videoFrame = frame.convertTo(AV_PIX_FMT_RGB32);
	w.videoSink()->setVideoFrame(videoFrame);
});

p.setSource("PATH-TO-VIDEO");
p.play();

At least I expect to see debug messages, but this is the only output:
