• run:

qmake
make

Usage

Link your app with the static build of QtAV:

libName = QtAV
android: libName = $${libName}_$${ANDROID_TARGET_ARCH}
LIBS += -L $build_path/QtAV/lib/ -l$${libName}
win32: libName = $${libName}.lib
else:linux: libName = lib$${libName}.a
else:mac:libName = lib$${libName}.a
PRE_TARGETDEPS +=  $build_path/QtAV/lib/$${libName}

INCLUDEPATH += $src_path/QtAV/src
DEPENDPATH += $src_path/QtAV/src
INCLUDEPATH += $src_path/QtAV/qml
DEPENDPATH += $src_path/QtAV/qml

To use QtAV in Qml register the types:

qmlRegisterType<QmlAVPlayer>("QtAV", 1, 7, "AVPlayer");
qmlRegisterType<QuickFBORenderer>("QtAV", 1, 7, "VideoOutput2");
qmlRegisterType<QtAV::VideoCapture>("QtAV", 1, 7, "VideoCapture");
qmlRegisterType<MediaMetaData>("QtAV", 1, 7, "MediaMetaData");
