Changelog: - Add QtAVWidgets module contains widget based renderers, video preview widget - QtAV module only depends on QtCore and QtGui - Improve audio output API - Simplify deployment on OSX. Deploy sdk from release packages without build. - Improve seekable detection - Fix noise audio if volume increased - Fix noise and wrong playback speed for wmv videos - Preview is more accurate - Do not copy AVPacket but use reference count. - Faster audio track switch - Reopen audio output only if audio format changed - VideoFrame: new API for converting to another format or QImage - OpenGL VAO, VBO support. - QML * Fix some crashes in QQuickItemRenderer * Add FBO item renderer and use the same code path as other opengl renderers * timeout property - player and QMLPlayer example * player: real time preview on progress bar * Fast seek and display if seek shortcut is pressed and hold

For QtAV version >= 1.3.4, QtAV can be installed as a Qt5 module easily. Integrating QtAV in your project is very easy.
First, you have to build QtAV. Then go to building directory, you will find sdk_install.sh and sdk_uninstall.sh (sdk_install.bat and sdk_uninstall.bat on windows). Run sdk_install.sh or sdk_install.bat to install QtAV as a Qt module.
To use QtAV, just add the following line in your project
CONFIG += av
For Qt5, use the following works too
QT += av
In your C++ files, add
#include <QtAV/QtAV.h>
In addition, you must copy ffmpeg and portaudio/openal libraries to Qt dir manually. Otherwise your application may not able to run in QtCreator. On windows, put the the dlls in QtDir/bin. On linux, put in QtDir/lib
Since QtAV 1.5 QWidget based renderers are moved to a new module QtAVWidgets. If you want to use QWidget based renderers, for example OpenGLWidgetRenderer, in project file add
QT += avwidgets
In your C++ files, add
#include <QtAV>
#include <QtAVWidgets>
Make sure QtAV::Widgets::registerRenderers() is called before creating a renderer.
For QtAV < 1.3.4
It's easy to include QtAV in your project. Because it's pro file are well designed. For more information about the pro file i use, see my another project: https://github.com/wang-bin/LibProjWizard4QtCreator
You can see examples in QtAV to know how to use QtAV, or follow the steps below
Steps
###1. Create a subdirs type project and a player project
myproject/myproject.pro
TEMPLATE = subdirs
SUBDIRS += libQtAV myplayer
myplayer.depends += libQtAV
libQtAV.file = QtAV/QtAV.pro
include(QtAV/root.pri)
###2. Put QtAV to myproject
You can use git clone git@github.com:wang-bin/QtAV.git in myproject/, or copy QtAV to myproject/. It's recommend to use git so that you can checkout the latest code easily.
the directory now is
myproject/myproject.pro
myproject/myplayer/myplayer.pro
myproject/QtAV/QtAV.pro
myproject/QtAV/src/libQtAV.pro
myproject/QtAV/src/libQtAV.pri
###3. Add libQtAV.pri in you player project
in myproject/myplayer/myplayer.pro, add
include(../QtAV/src/libQtAV.pri)
###4. generate Makefile
qmake
or
qmake -r
###5. make
you player binary will be created in bin under build dir. If you are in windows, the QtAV dll also be there
Note: for windows user, if you run qmake(command line build. QtCreator uses qmake -r by default) you may run qmake twice. otherwise make may fail.
