[Tips] : Poor's man screen capture using adb

[bahathir]

Most of the time I am using Android SDK's ddms for screencapturing. Based in this link, we can use adb to pull framebuffer image content, and convert it to png or any standard file format.


http://stackoverflow.com/questions/2807070/screenshot-of-the-nexus-one-from-adb

$ adb pull /dev/graphics/fb0
$ ffmpeg -vframes 1 -f rawvideo -pix_fmt rgb32 -s 544x960 -i fb0 fb0.png

I am not using dd to create correct raw file size, but, ffmpeg can sort them out, without any problem.

The key is the resolution for RAZR, which is 544x960.

Here I attached the screenshot which I made using this method.
Note: I changed the launcher to stock Android Launcher2, it brings the 'Nexus One' feels.

Thank you.

Yes, screen capture apps are easier. This adb method is an alternative to ddms.

Can you use screen capture apps WITHOUT rooting the phone ?

Sorry wrong thread

I've been searching for a way to make a screenshot of the HTC One S recovery for 2 days and this guide got me nowhere at first because the One S resolution is 540x960 and i thought the OP recommended 544 is wrong.
Well, now after 2 days i realize it is right actually. So, the One S is identical to the Droid RAZR. Pretty cool. Thanks for this handy thread!
Maybe worth explicitly stating on the OP, that the resolution in Framebuffer is not equal the actual display resolution haha...

I can pull shots from TWRP Recovery now with these lines:

adb pull /dev/graphics/fb0
ffmpeg -vframes 1 -f rawvideo -pix_fmt rgb565 -s 544x960 -i fb0 fb0.png

Thanks again guys...

I use this in my .bashrc on OSX.

## Take a screenshot of the currently attached android's screen
alias adb_screengrab='adb shell screencap -p | perl -pe "s/\r\n/\n/g" > screen-$(date +"%Y%m%d-%H%M%S").png'

I know this works on my handsets, but I haven't tried it booted into in any recovery images.
