Make app for Android

FFmpeg

Get prebuilt packages for android from http://sourceforge.net/projects/qtav/files/depends/FFmpeg/android/

extract and put include/* lib/* to QtInstallDir/{include,lib}

QtCreator

Download the binary archive: QtCreator

Unpack it where you like, e.g. '/opt/qtcreator'

The QtCreator customization is quite minimal. Only paths to sdk, ndk, ant should be specified. And also path to qmake, e.g. /opt/qt5/arm/bin/qmake

There many articles with screenshots explaining this on the Internet.

QtAV

Now the main things!

Get QtAV:

git clone https://github.com/wang-bin/QtAV

Then launch QtCreator and open the project QtAV ( QtAV.pro). Add Android kit for armeabi-v7a and build the project with the button with a hammer The directory will appear like this: build-QtAV-Android_armeabi_v7a_GCC_4_8_Qt_5_2_1-Release

You would have different dependently on you compiler or if you have specified other name. So, we have two directories:

Run sdk_install.sh in build dir. This will copy QtAV libraries to Qt dir to make sure we can create apk correctly.

Now try create an application:

Widget App

The renderer ids you can use are VideoRendererId_OpenGLWindow, VideoRendererId_OpenGLWidget, VideoRendererId_Widget, VideoRendererId_GraphicsItem. You can not use GLWidgetRenderer2 because the widget will be covered by other widgets.

QML App

qtcreator -> new project -> App -> App Qt Quick Choose, for example Qt Quick 2.2 Check Android kit in the checkbox.

An empty project will be created.

import QtQuick 2.5
import QtQuick.Window 2.2

Window {
    visible: true
    width: 360
    height: 360

    MouseArea {
        anchors.fill: parent
        onClicked: {
            Qt.quit();
        }
    }

    Text {
        text: qsTr("Hello World")
        anchors.centerIn: parent
    }
}

Change the above into the following:

import QtQuick 2.5
import QtQuick.Window 2.2
import QtAV 1.6

Window {
    id: window1
    visible: true
    width: 360
    height: 360

    Text {
        height: 16
        text: qsTr("Qt+QtAV+FFmpeg")
        anchors.right: parent.right
        anchors.rightMargin: 13
        anchors.top: parent.top
        anchors.topMargin: 8
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.horizontalCenterOffset: 68
    }

    VideoOutput {
                anchors.right: parent.right
                anchors.rightMargin: 13
                anchors.bottom: parent.bottom
                anchors.left: parent.left
                anchors.top: parent.top
                anchors.bottomMargin: 15
                anchors.leftMargin: 14
                anchors.topMargin: 60
                source: player
    }

    AVPlayer {
                id: player
                source: "http://blablabla/video/test.mp4"
    }

    MouseArea {
                anchors.rightMargin: 0
                anchors.bottomMargin: 0
                anchors.leftMargin: 0
                anchors.topMargin: 0
                anchors.fill: parent
                onClicked: {
                    player.play();
                }
    }
}

Create AndroidManifest with QtCreator. The default settings are acceptable.

Add the following lines to the project file *.pro:

QT += av

Now we can launch it. There will appear the virtual device selection. We can choose any compatible device from the list, or create a new one.

After that there will be the APK-file in the build directory

build-XXXXXX-Android_armeabi_v7a_GCC_4_8_Qt_5_2_1-Release/android-build/bin/QtApp-debug.apk
