Release version not playing video and not loading external css

[andyhaggis]

Hi. I am trying to deploy my windows GUI application. I ran the executable through DependecyWalker and added all the missing DLL files, so the program starts up. I had troubles with images not saving to file after downloading. but after I added the "plugins\imageformats" folder to my program folder everything with images is working like a charm. My problem is now that DependecyWalker does not report any missing DLLs, but my app does not show the video. The QVideoWidget is just white. It works fine on my development computer through QT Creator, but no success when testing the release on my virtual machine.

Second issue is that a webview does not load the CSS file from the webserver, even though I have added:

settings->setAttribute(QWebSettings::AutoLoadImages, true);
settings->setAttribute(QWebSettings::PluginsEnabled, true);
settings->setAttribute(QWebSettings::LocalStorageEnabled, true);
settings->setAttribute(QWebSettings::LocalContentCanAccessRemoteUrls, true);
settings->setAttribute(QWebSettings::JavascriptEnabled, true);
settings->setAttribute(QWebSettings::LocalContentCanAccessFileUrls,true);

Again, it works on my development computer, but not on the release virtual machine.

Does anyone know which folders and/or dlls I am missing for videos to show uo and external CSS to load? Thanks in advance.
