使用ADB捕获屏幕 [英] Using ADB to capture the screen

问题描述

我正在尝试尽快获取手机屏幕的屏幕截图。
目前，我正在做：

I'm trying to get a screenshot of the phone screen as fast as possible. Currently, I am doing:

adb shell screencap -p /sdcard/screencap.png && adb pull /sdcard/screencap.png         

然而它太慢了，需要3秒钟。
有没有更好的方法呢？我打算在无根电话下使用此功能。

However it is too slow and takes up to 3 seconds. Is there any better way to do this? I intend to use this function with an unrooted phone.

我还可以使用哪些不同的参数进行screencap？

Also what are the different arguments I can use for screencap?

谢谢。

编辑（额外信息）：我打算使用此方法将屏幕的实时馈送到我的电脑上。目前的方法有效但速度太慢。我无法使用 adb shell screenrecord 因为我在录制时无法访问该视频文件。

EDIT (extra information): I intend to use this method to be able to get a live feed of the screen onto my pc. The current method works however it is too slow. I can't use adb shell screenrecord because I won't be able to access the video file while it is being recorded.
