的Nexus One的亚行截图? [英] Screenshot of the Nexus One from adb?
问题描述
我的目标是能够从连接通过USB接口一个根深蒂固的Nexus One键入一个单词的命令,并得到一个截图。
My goal is to be able to type a one word command and get a screenshot from a rooted Nexus One attached by USB.
到目前为止,我可以得到我相信这是一个 32位xRGB888
原始图像向外拉,像这样的帧缓冲:
So far, I can get the framebuffer which I believe is a 32bit xRGB888
raw image by pulling it like this:
adb pull /dev/graphics/fb0 fb0
在那里,虽然,我有一个很难得到它转换为PNG。我试图用的ffmpeg是这样的:
From there though, I'm having a hard time getting it converted to a png. I'm trying with ffmpeg like this:
ffmpeg -vframes 1 -vcodec rawvideo -f rawvideo -pix_fmt rgb8888 -s 480x800 -i fb0 -f image2 -vcodec png image.png
这是创建具有零件隐约类似于屏幕上可爱的紫色的形象,但它绝不是一个干净的屏幕截图。
That creates a lovely purple image that has parts that vaguely resemble the screen, but it's by no means a clean screenshot.
推荐答案
有关ICS一个大大简单的解决方案是使用命令行下面的
A vastly easier solution for ICS is to use the following from the command line
adb shell /system/bin/screencap -p /sdcard/screenshot.png
adb pull /sdcard/screenshot.png screenshot.png
这会保存screenshot.png文件在当前目录。
This'll save the screenshot.png file in the current directory.
