• Auto resize to fit the screen resolution of the device
• Zoom window as your wish and keep the ratio
• Support customized 'screencap' for speeding up (RGBA32, RGB888, RGB565)
• Auto enable compressed data transfer if 'minigzip' found on the host
• 1~2FPS on MSM8625 device (1.2G dual core, 512M memory, 800x480)

Non-feature:

• Not support multi devices pluged in at the same time.
• Not support landspace mode (default in portrait mode).

Additional Key Map

You can press F1/2/3/4 on you keyboard to emulate the following Android key.

F1 AKEYCODE_HOME F2 AKEYCODE_BACK F3 AKEYCODE_CALL F4 AKEYCODE_ENDCALL

Pre-requirements

Mandatory:

• Linux, any distribution with Qt package.

• Qt 4.6+ installed in your system

• screencap command on the target device

  $> adb shell ls /system/bin/screencap /system/bin/screencap

  If the output indicates: 'No such file or direcotry', you can use the tool except install one by yourself.

  the 'screencap' source code presents in frameworks/base/cmds/screencap.

• PC: adb command is availible in your search path, check it:

  $> which adb /usr/bin/adb

• USB cable connected to your android device

Optional:

• Android device in engineer mode (Rooted), So that you can get root permission in adb shell

  $> adb root $> adb shell id uid=0(root) gid=0(root)

• minigzip installed on your PC (For compressed image transfer)

  There is a precompiled x86_64 minigzip binary in the contirbutes dir, just copy into your system path:

  $> sudo cp contributes/minigzip /usr/bin

  If you want to compile one for yourself, get it from android/external/zlib

  $> cp -rf android/external/zlib zlib-pc $> cd zlib-pc $> ./configure $> make $> sudo cp minigzip /usr/bin

  You'll be appreciated If you can help to add decompress code in to this project to help to avoid runing external program to decompress frame buffer data.

Compile

$> apt-get install qt4-qmake libqt4-dev libqtcore4 libqtgui4 $> make $> ./build/seven-square

Or you can create a short cut on your desktop.

Keypad support

If you want support more key define in the UI, please read the contributes/generate-keymap.sh for more info.

History

'Seven Square' was a game I played when I was a child, and I wrote a QT version for it. And now it's the base code of this android screen cast tool.
