I got a camera, plugged to my PC via the network socket. I do not know how to set the source stream!

this is the code I wrote before to set the source of a file and play video,



void PlayVideo::rollOn()
{

media = new Phonon::MediaObject(movieLabel);
media->setCurrentSource(Phonon::MediaSource(QString("/home/saman/4.7/phonon_test/sample.mp4")));
//media->setCurrentSource (Phonon::MediaSource());
videoPlayer = new Phonon::VideoPlayer(Phonon::VideoCategory, movieLabel);
videoPlayer->setFixedSize(QSize(400, 300));
videoPlayer->show();

connect(videoPlayer, SIGNAL(finished()), videoPlayer, SLOT(deleteLater()));
videoPlayer->play(media->currentSource());
}


could anyone tell me how to change the source stream so that I can get video via
network socket?

this is the sample code of getting packet via network, i don't know how to buffer the received data
and send it as a source stream to phonon video.



void PlayVideo::rollOn()
{

udpSocketin = new QUdpSocket(this);

udpSocketin->bind(localPort);

connect(udpSocketin, SIGNAL(readyRead()),this, SLOT(readDatagrams()));

QDataStream out(&datagramout, QIODevice::WriteOnly);

out.setVersion (QDataStream::Qt_4_7);

timer2 = new QTimer(this);

connect(timer2, SIGNAL(timeout()), this, SLOT(playbuff()));

media = new Phonon::MediaObject(movieLabel);

media->setCurrentSource(Phonon::MediaSource(QString("/home/saman/4.7/phonon_test/sample.mp4")));

//media->setCurrentSource (Phonon::MediaSource());

videoPlayer = new Phonon::VideoPlayer(Phonon::VideoCategory, movieLabel);

videoPlayer->setFixedSize(QSize(400, 300));

videoPlayer->show();

connect(videoPlayer, SIGNAL(finished()), videoPlayer, SLOT(deleteLater()));

videoPlayer->play(media->currentSource());
}

void PlayVideo::readDatagrams()
{
if(udpSocketin->hasPendingDatagrams ())
{
datagramin.resize (udpSocketin->pendingDatagramSize ());

qint64 receiveBytes = udpSocketin->readDatagram (datagramin.data (), datagramin.size ());

if(receivedBytes <= 0)
{
qDebug("receivedBytes <= 0");
}
}
}
