In the future if any one has this issue here is the code that worked for me:
const std::string &url = "ms-appx:///temp.mp4";
auto dispatcher = cocos2d::GLViewImpl::sharedOpenGLView()->getDispatcher();
m_panel = cocos2d::GLViewImpl::sharedOpenGLView()->getPanel();
if(dispatcher->GetType() && m_panel->GetType()){
dispatcher->RunAsync(Windows::UI::Core::CoreDispatcherPriority::Normal, ref new DispatchedHandler([this, url]() {
auto mediaElement = ref new Windows::UI::Xaml::Controls::MediaElement();
mediaElement->Width = 200;
Windows::Foundation::Uri^ uri = ref new Windows::Foundation::Uri("ms-appx:///temp.mp4");
mediaElement->Source = uri;
mediaElement->AutoPlay = true;
mediaElement->IsFullWindow = true;
mediaElement->Name = "Intro";
mediaElement->IsMuted = false;
m_panel.Get()->Children->Append(mediaElement);
log("play");
}));
}
Also add you video to you assets for both Windows and Windows phone.
Hope this helps someone in the future!
