Not able to play Videos with QMediaPlayer and QVideoWiget in Qt 5.2

[sky]

Hi,

I have been trying to play video formats *.wmv, *.mp4 with QMediaPlayer and QVideoWidget in Qt5.2. I just followed the expample and here is my code:

mp =new QMediaPlayer(this);
    vw = new QVideoWidget(this);
    QMediaPlaylist* playlist = new QMediaPlaylist(this);
    playlist->addMedia(QUrl::fromLocalFile("C:/Users/Public/Videos/Sample Videos/Wildlife.wmv"));
    playlist->setCurrentIndex(1);
    mp->setPlaylist(playlist);
    mp->setVideoOutput(vw);
    setGeometry(100,100,400,500);
    vw->setGeometry(0,0,300,400);
    show();
    play();

mp =new QMediaPlayer(this);
    vw = new QVideoWidget(this);
    QMediaPlaylist* playlist = new QMediaPlaylist(this);
    playlist->addMedia(QUrl::fromLocalFile("C:/Users/Public/Videos/Sample Videos/Wildlife.wmv"));
    playlist->setCurrentIndex(1);
    mp->setPlaylist(playlist);
    mp->setVideoOutput(vw);
    setGeometry(100,100,400,500);
    vw->setGeometry(0,0,300,400);
    show();
    play();

I have installed the K-Lite codecs. When I play the same files using Media Player Classic or Win Media Player the files play well and the the Lca and FFmpeg icons show up in the tray.

But with Qt 5.2 I am not able to see any visuals for any video file. Only for wmv files I am able to hear audio(no visual).

I have searched a lot on the web and everybody points to codecs which I believe I have. Does the configuration of the K-Lite codecs matter? I have used the default codecs. I have built Qt with the Win media foundation too. So I am at a loss to understand what is wrong here. Platform is win7 32.
Any help is appreciated. Do let me know if I have to reading anything or any article or blog. Thank you.

The question is what compiler with Qt 5.2.1 are you using? Opening just .AVI video? you're using MinGW. Opening other formats, use VS2012.
I have mine doing .MOV, .AVI, .MP4 working with VS2012 64 bit and 32 bit. While .AVI working with MinGW.
think your issue is that the VS2012 and VS2010 have DirectX Support, while I believe that MinGW doesn't.
Have to say out of the box video without Phonon manual configuring is nice.
oh I use Qt 5.2.0 Windows 8.1 haven't tried it in Ubuntu or Mac land yet

Hi Budda,

Thanks for the reply.
The compiler is MSVC++ 2010. I have been using the same platform, same compiler, codecs with 4.8.5. And it works all well.
Now I am trying to move to Qt5.2. And I am facing this problem. The problem is with all formats. Only with wmv files I am able to hear the audio.
