You need to connect to the featurePermissionRequested of the WebView, i.e. onFeaturePermissionRequested: { grantFeaturePermission(securityOrigin, feature, true); }

hello Are you able to fix the problem or still facing the issue on wayland-egl ?

@NelsonC The problem with it I found was how to fetch the mailto link when clicked on the link. Once you get the mailto link then you can call Qt.openUrlExternally and pass the link as parameter and it should open the default mail client. For eg: onClicked: Qt.openUrlExternally("mailto:someone@example.com?Subject=Hello")

Hello. I just did a Test Deploy on a Windows 10 and a Windows 7 Clean VM Machine. Qt Version is 5.5.0 I know this is about Embedded Linux and around 5 Months old. But I have the same Problem. It is exactly the same Error Message. Does anybody found a real working Solution yet? The .pak File is in my Application Main Folder. I created a qt.conf and tried the following Settings: [Paths] Prefix=<QCoreApplication::applicationDirPath()> Prefix=<> Prefix=<\> Prefix=<&PWD> Nothing worked so far. I could not find the answer, how to tell Prefix to use the current Directory. In addition: Has anybody created a BR yet? If not, I can do this. Thanks Oliver EDIT01: Finally I found a way to make it work: [Paths] Prefix=. Time will tell if this will bring up other Bugs, Glitches etc.

I'm using QtWebEngine 5.12.12, tied to this version for my application. I rebuilt it with -webengine-proprietary-codecs and the mp4 videos work now but the occ/webm videos stopped working!!??!? Has anyone seen this or have any advice? I'm using this page to test: https://tekeye.uk/html/html5-video-test-page

There is some additional information on this issue in the JIRA at https://bugreports.qt.io/browse/QTBUG-45122

AFAIK there is no way to do this in Qt 5.4.1 I'm also waiting for an option to pass command line parameters to be able to set a proxy - that's the only way to set proxy in Blink (and I'm afraid we'll have to forget about proxyForUrl - not a big deal but... Webkit could be removed after 5.6 so we'll have to stick to old versions...) but you can try Qt 5.5 alpha announced here http://blog.qt.io/blog/2015/03/17/qt-5-5-alpha-available/ According to this section "Updated Qt WebEngine and Qt WebView" they are working on settings "Qt WebEngine now provides APIs for ... as well as settings" Honestly I don't know if that includes command line parameters/settings... BTW Still no binaries so you'll have to build it yourself or wait for beta HTH
