    Adds support for raw yuv files for 422/444 · 090f4d4b
    Deb Mukherjee authored 
    Adds support for raw yuv inputs in 422/444 sampling for use
in profiles 1 and 3.
New options added to vpxenc are:
--i422 and --i444, which are to be used in conjunction with
--width, --height, and --fps for proper raw yuv handling.
A new option is added to vpxdec:
--rawvideo, which enforces raw yuv video output for the
bit-stream decoded irrespective of 420, 422 or 444 sampling.
The existing options --i420 and --yv12
are specialized for use only for 420 content.

\title Porting QML Applications to Qt 5 Example
30 
\brief Provides step-by-step instructions to port a QML application to Qt 5.
31
32 
The new version of Qt Quick in Qt 5 brings in some changes to the way QML
33 
applications are developed. For the complete list of changes that affect
34 
existing QML applications, refer to \l{Porting QML Applications to Qt 5}.
35
36 
This topic will walk through the porting process to make the \c{flickr} Qt 4
37 
QML demo work on Qt 5. If you have the SDK based on Qt 4.8 installed, you can
38 
find this demo application under
39 
\c{<install_dir_root>/Examples/4.x/declarative/demos/}.
40
41 
The \c{flickr} application is a complete application that comes with a launcher.
42
43 
Follow these step-by-step instructions to make the \e{flickr} Qt 4 QML
44 
application work on Qt 5:
45 
\list 1
46 
 \li Edit all the \c{.qml} files and replace \c{import QtQuick 1.0} statements
47 
     with \c{import QtQuick 2.0}.
48 
 \li Add the additional \c{import QtQuick.XmlListModel 2.0} statement to
49 
     \c{qml/common/RssModel.qml}.
50 
     \note XmlListModel is part of a submodule under QtQuick and it must be
51 
           imported explicitly to use it.
52 
 \li Make the following changes to
53 
     \c{qmlapplicationviewer/qmlapplicationviewer.h}:
54 
  \list
55 
   \li Replace the \c{#include <QtDeclarative/QDeclarativeView>} with
56 
       \c{#include <QQuickView>}.
57 
   \li Replace \c{QDeclarativeView} with \c{QQuickView} in the class
58 
       declaration for \c{QmlApplicationViewer}.
59 
   \li Replace the parameter for \c{QmlApplicationViewer} constructor from
60 
       \c{QWidget} to \c{QWindow}.
61 
  \endlist
62 
 \li Make the following changes to
63 
     \c{qmlapplicationviewer/qmlapplicationviewer.cpp}:
64 
  \list
65 
   \li Replace all the \c{QtCore} and \c{QtDeclarative} include statements with
66 
       these:
67 
    \code
68 
      #include <QCoreApplication>
69 
      #include <QDir>
70 
      #include <QFileInfo>
71727374757677787980818283848586878889909192939495
#include <QQmlComponent> #include <QQmlEngine> #include <QQmlContext> #include <QDebug> \endcode \li Replace all instances of \c{QWidget} with \c{QWindow}, and \c{QDeclarativeView} with \c{QQuickView}. \li Remove the code between \c{#if defined(Q_OS_SYMBIAN)} and \c{#endif} macros as Symbian platform is not supported in Qt 5. \li Remove the code between \c{#if QT_VERSION < 0x040702} and \c{#else}, and \c{#endif // QT_VERSION < 0x040702} macros towards the end. \endlist \li Run the \c{qmake} and \c{make} utilities to build the application. \note Ensure that the \c{PATH} environment variable is pointing to the Qt 5 binaries and libraries directories, before running \c{qmake}. \endlist Run the \c{flickr} application to see whether it behaves as expected. Here is a snapshot of the application running on Ubuntu v12.04: \image flickr_application.png \section1 Related Topics \l{Porting QML Applications to Qt 5} */
