QWebview, HTTP proxy, html5 video does not work

[anaksimandr]

Hi All,

I'm using QWebView to show chat log.

@webView = new QWebView(this);
QWebSettings::globalSettings()->setAttribute(QWebSettings::PluginsEnabled, true);
webView->settings()->setAttribute(QWebSettings::PluginsEnabled, true);
webView->settings()->setAttribute(QWebSettings::LocalStorageEnabled, true);
webView->settings()->setAttribute(QWebSettings::PrivateBrowsingEnabled, true);
webView->settings()->setMaximumPagesInCache(0);
webView->settings()->setAttribute(QWebSettings::DeveloperExtrasEnabled, true);@

If the proxy for QWebView is not set the HTML code like this works fine.
@<iframe width="100%" height="315" frameborder="0" allowfullscreen src="http://www.youtube.com/embed/" + rxYouTube.cap(11) + "" ></iframe>"@
But when I do something like this
@QNetworkProxy proxy;
proxy.setType(QNetworkProxy::HttpProxy);
proxy.setHostName("ip");
proxy.setPort(port);
proxy.setUser("login");
proxy.setPassword("passsword");
QNetworkProxy::setApplicationProxy(proxy);@

YouTube tells me that my browser does not supports HTML5.

How I can solve this problem?

PS Platform: Qt 4.8, Windows, VC

Have you tested this proxy on other HTML5 browser?
Is it transparent proxy?

Yes, it is transparent proxy - SQUID.
In other browsers proxy works fine (tested google chrome, maxthon).

Have no idea how could I help you then.... You should maybe fire a BUG on Qt's bugtracker...
