I downloaded and installed two versions of Qt, one is 5.9.4 and the other is 5.11.2. On operating system, one is shown with Community tag and the other with Enterprise tag. I wonder what the difference is:
To clarify, I think I downloaded open-source version of Qt 5.11.2, but it is tagged as enterprise.

I have already created Qt based application which uses some third-party open source library like OpenCV, I have looked Windows Dev Center and seems the all the reference is using Visual Studios and other Windows tool. I have created my App using Qt creator. Is it possible to submit such an application on Windows App store?
Any help will be appreciated,
Thanks
Haris
Bad news: Microsoft does not support Win32 apps on AppStore yet (but it has been announced, currently under development as "Project Centennial"). It looks like an "old-school" desktop applications cannot be submitted to the Windows App store.
Good news: Qt has support for WinRT (complete in Qt 5.6 which is currently in Beta and will be released in a few weeks). And qmake can generate a Visual Studio solution from your project (in case you need it for deployment or debugging; VS Community edition is free).

On the qt-project web-site there're available sources as for porting QML to iOS, Android.
http://qt-project.org/doc/qt-5/portingtoandroid.html
http://qt-project.org/doc/qt-5/porting-to-ios.html
It appears to be easy.
Is it so for Windows Phone as well?
Is it so for any other platform?
Qt Project has a Qt for WinRT tutorial providing a step-by-step process to build applications for Windows 8 based devices. Basically to resume the tutorial :
You need the appropriate windows runtime
You may have to build Qt from source for that runtime library
You develop and compile Qt as you would do for a desktop app
You have an additional step for packaging the application.
I have developed a custom media player that works on Windows 7. I used QMediaPlayer, QVideoWidget and QMediaPlaylist classes. I need to port the app to Linux. Do these classes also exist for Linux? Do they come automatically when installing Qt?
I tried copying the project to my Linux partition and recompiling but it can not find the headers.
Check weather the major version of Qt is the same on both platforms.
Seeing your description, I believe you are using an older version of Qt on the Linux machine as compared to the Windows machine.
Hope this helps.
Qt Digia provides cross platform development targeting Mac, PC, Linux and on mobile iOS, Android, Windows mobile.
The Qt project also offers iOS, Android and PC, Mac, Linux builds. What is additionally there on the commercial version (i.e. Qt Digia)?
The core is the same which means the essential modules and some shared extension modules, aka. add-ons. There are a couple of things differing, however, e.g.:
Boot2Qt
Android injection
Qt Virtual Keyboard
Qt Quick Compiler
Charts
Qt Purchasing
... and so on, basically anything that Digia is working on under the Enterprise umbrella. You can follow their blog for further details.
Here you can also find the updates for 5.3.
On the new qt.io download page you can find a detailed table with a comparison about the available options.
The number of mobile operating systems or platforms supporting QT based app development keeps growing. Not for all of them QT is the standard framework for building apps, therefore it seems the Qt support can be categorized as follows:
Qt and Qt based technologies (QML, QtQuick, QtMobility) are the recommended way for building mobile apps and part of the SDK.
Qt or a subset of Qt is supported as a secondary way of developing or porting apps, and there is support for a subset of QT APIs within the SDK.
Unofficial 3rd party or open source extensions enable development of Qt based apps for a platform.
Which mobile operating systems or SDKs do support development of apps using Qt in either of the above listed ways?
Mobile operating systems with full Qt support in the SDK:
Nokia Symbian OS: http://www.developer.nokia.com/Develop/Qt/. Since Nokia discontinued Symbian, Qt for Symbian is a community effort now.
Nokia N9 / MeeGo 1.2 Harmattan: Full Qt support.
Mer (community Meego fork) and Sailfish OS: Qt/QML are both supported.
Canonical's Ubuntu Phone uses the Ubuntu QML toolkit and Qt Creator for native application development.
Mobile operating systems supporting a subset of the QT APIs:
Blackberry 10 OS and SDK: The Blackberry 10 SDK contains the Cascades UI framework, which is built on top of a subset of Qt 4.8 and QtMobility modules. Apps can be created using Qt, QtMobility and QML/QtQuick. Another approach is porting an existing Qt application that uses QtGui.
Digia, community driven (open source) and 3rd party extensions targeting mobile operating systems:
Android: QT 5 port by Digia (demoed at Qt Developer Days Berlin in Nov 2012), expected to be released by the end of 2013.
iOS: QtQuick 1.0 port by Digia (demoed by Qt Developer Days Berlin in Nov 2012), expected to be released by the end of 2013.
WinRT / Windows 8: (demoed by Qt Developer Days Berlin in Nov 2012) demo.
Qt for Android port Necessitas: Has been donated to the Qt project in Nov 2012.
Qt SDK for iOS devices by Mediator Software: The product website does not contain much information, but there are regular updates on Twitter Qt4iOS (links to apps in Appstore built using QT SDK for iOS are posted on Twitter).
