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.
- You need to have a Phonon::MediaObject
- You need to have a Phonon::VideoWidget
- You need to have a Phonon::AudioOutput
- 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:
obj_MediaObject->clearQueue();
//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:
obj_MediaObject->play();
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.
