Phonon minimum needs to play a video.

The documentation about Phonon provided by Qt doesn't give you an "out of the box" explanation on how to play a video using Phonon in Qt. That's why I write this down in order to help a little.

Before you start testing, make sure that you have the right programs and or libs installed on your computer. Look here for the setup you need.

You need only 4 items to get a video to play.

  1. You need to have a Phonon::MediaObject
  2. You need to have a Phonon::VideoWidget
  3. You need to have a Phonon::AudioOutput
  4. add your .pro file with "+= phonon"

Then the code:

//include the right lib:
#include <phonon>

// setup the objects:
Phonon::MediaObject *obj_MediaObject = new Phonon::MediaObject(this);
Phonon::VideoWidget *wid_videoWidget = new Phonon::VideoWidget(this);
Phonon::AudioOutput '''aio_audioOutput = new Phonon::AudioOutput(Phonon::VideoCategory,this);

//clear the mediaobject:

//Put a video in the queue:
obj_MediaObject->enqueue(Phonon::MediaSource("path to video"));

//make the proper connections:
Phonon::createPath(obj_MediaObject, wid_videoWidget); // to link the mediaobject with the video widget.
Phonon::createPath(obj_MediaObject, aio_audioOutput); // to link the mediaobject with audio output.

//play the video:

That's all there is.

Note: This code only works on local video files. I didn't have YouTube videos and mms streaming working yet. When I do, I will edit this page.

It's off course also possible for others to edit a working code.
