How to play HTML5 video file on i.MX6 with QtWebKit

njozwiak

Hi all,

I have cross built Qt 5.4.2 for the i.MX6 with QtWebKit and I am trying to get video files to play using HTML5. I have a very simple demo application that uses WebView to display an HTML page. That page uses an HTML5 video tag to reference a local video file. When the page is displayed, the video controls appear on the screen fine and even show the proper duration for the sample video file. I can press play and the timeline slider moves like the video is playing, but I never see any video frames on the screen.

I validated that I can play this video file manually using gstreamer-1.0 that is built into the root file system. So it's not an issue with GStreamer or the video file itself. I understand Qt must interface with GStreamer somehow for playing these video files. Clearly it's not happening automatically. How do I troubleshoot this? Any ideas on what could be going wrong?

Thanks

main.cpp

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QWebView view;
    view.load(QUrl("file:///home/root/content/page.html"));
    view.show();
    return app.exec();
 }
