Default: 5

or "192.168.56.102:5555")

You need to know digitizer device input number, which is specific to every device and ROM.
Use command
adb shell getevent -land move finger on screen. You will see something like
/dev/input/event2: EV_SYN SYN_REPORT 00000000
/dev/input/event2: EV_ABS ABS_MT_WIDTH_MAJOR 00000014
/dev/input/event2: EV_ABS ABS_MT_POSITION_X 00000247
/dev/input/event2: EV_ABS ABS_MT_POSITION_Y 0000030c
/dev/input/event2: EV_ABS ABS_MT_TOUCH_MAJOR 0000001a
/dev/input/event2: EV_ABS ABS_MT_TOUCH_MINOR 0000000e
/dev/input/event2: EV_ABS 003c ffffffb3
In your case device you are looking for has number 2.
You can now start screen capturing. Download latest scrollscreenshot binary, unlock screen, start app you want to scroll-capture and type (replace 2 by your device input number):
java -cp scrollscreenshot-latest.jar com.pgssoft.scrollscreenshot.ScrollScreenShot -i 2
If eveything goes well, you will get file out.png with something like:
Left-to-right mode will give you something like this:
- scrolling in all 4 directions
- automatic detection of scroll area edge
- 0.1 - initial release, only top-down scrolling for first device found by ADB
- 0.2 - scrolling top-down and left-right, stitch now works in smooth/none/separate modes, ADB device can be choosen by id
- 0.3 - fixed NPE when using separate stitch mode
