Media Player Example
Playing audio and video.
Media Player demonstrates a simple multimedia player that can play audio and or video files using various codecs.
To activate the various functions such as play and stop on the dialog, the button clicked events emit the play() and stop() signals, which are connected to the play() and stop() slots of QMediaPlayer.
connect(controls, SIGNAL(play()), player, SLOT(play())); connect(controls, SIGNAL(pause()), player, SLOT(pause())); connect(controls, SIGNAL(stop()), player, SLOT(stop()));
We can get the volume (and set our user interface representation)
and we can make widget 'volume' changes change the volume
connect(controls, SIGNAL(changeVolume(int)), player, SLOT(setVolume(int)));
The example also allows us to change video properties by means of the QVideoWidget object. We can go to Full Screen mode with a single button click, and back again.
