Hello Friends,

I have a Phonon Media object. I am able to play, pause or stop it but i couldnt play it fast or slow. Here is my object:

m_phononMediaObject = new Phonon::MediaObject;
QString fileName("C:/trn_parallel_25_adj.mpg");
m_phononMediaObject->setCurrentSource(fileName);

Phonon::createPath(m_phononMediaObject, m_phononVideoWidget);
m_phononMediaObject.play();

Waiting for your helps..
