When running an application in QT5 made ​​using the QWebView , I accessed a page with a video player in HTML5 , but the video does not play and qt/directshow shows the following error: DirectShowPlayerService::doRender: Unresolved error code 80040218 DirectShowPlayerService::doRender: Unresolved error code 80040218 Details: QT5.1.1 MingW4.8 32bit Windows 7 64bit I suspect that is why my Windows is 64bit , but the QT/MingW * runs on 32bit and maybe miss some DLL/LIB .

I've bundled some HTML and PNGs in my Qt app's resources file (for the help system). Unfortunately I can't find a way for the HTML to display images. I've tried various combinations of the QWebView 's base URL, and different URLs for the <img> tag but none have worked so far. To be clear, I want to be able to do something like this: QString html = "<html><img href=':/resources/cat.png'/></html>"; myWebView->setHtml(html, ???); Is this possible? Try your resource format as: qrc:/resources/cat.png instead of :/resources/cat.png we have .css files that use images in such a format within webview

Following the caveat section on QWebElement , I have worked my way around showing/hiding the on-screen

How to pass a function "pointer" from JavaScript to a slot? in JavaScript: function f1() { alert("f1"); } qtclass.submit(f1); and in Qt: public slots: void submit(void * ptr) { (void)ptr; } I need the "f1", function to get fired in the JavaScript from the c++, once some processing is done.
