We are using QWebEngine to drive a hybrid app (Html5 + Javascript + C++) on windows.  According to QWebEngineFeatures Doc, http://doc.qt.io/qt-5/qtwebengine-features.html#pepper-plugin-api
You must pass a flag to qmake, WEBENGINE_CONFIG+=use_proprietary_codecs, and build Qt from source yourself in order to support h.264 video decoding.

In researching this, I became aware that Cisco provides a downloadable binary codec, where Cisco pays the MPEG-LA royalties.   Apparently this is the method used
To provide h.264 playback in Firefox.  If you watch the intellectual property rights video at http://vimeo.com/cullenfluffyjennings/openh264-ipr, they explain why they
Did this, and how you can even make changes to the codec via open source if needed.

Would it make sense for QWebEngine to support this codec, in order to be able to provide ‘out of the box’ (via download at end user’s computer), support for h.264 playback in <video> tags?
