如何使双击采用了android的adb命令，扩大视频画面 [英] How to make a double tap to expand the video screen using android adb commands
问题描述
我试图分析在我的Android设备中的视频流。我想要的一切由脚本自动化，因为该设备具有重复试验了很多次，我想远程操作（这是LAN连接）。对于这一点，我使用的是特殊的应用程序，它开始进入流的小尺寸屏幕上的视频（这是专门为这，我必须扩展屏幕，我只能使用这个Android应用程序）。双抽头提出，要扩大屏幕（没有按键扩大，我可以做到这一点只有双攻手动）。
I am trying to analyze a streaming video in my Android device. I want everything automated by scripts, because the device has to repeat the test a lot of times and I want to do it remotely (it is LAN connected). For that, I am using a special app, which starts to stream the video on a small-sized screen (it is special for that, I must expand the screen and I must use only this android app). A double-tap should be made to expand the screen (there is no button to expand, I can do it only double-tapping manually).
由于我的自动化，我想，当视频流被执行下面从一个批处理文件扩展视频画面：
Due to my automation, I am trying to expand the video screen from a batch file when the video is streaming executing the following:
adb shell input tap x1 y1
adb shell input tap x1 y1
但它不工作。我也试图与输入的触摸屏，输入刷卡X1 Y1 X1 Y1，我把每个组合在一个无限循环，而且它永远不会扩大。也许因为双击实在是太慢了....也许是因为该事件需要发送一个抽头释放事件。
But it does not work. I've tried also with input touchscreen, input swipe x1 y1 x1 y1, I put every combination in a infinite loop, and it never expands. Maybe because the double tap it is too slow.... or maybe because that event needs to send a tap-release event.
已经遇到了这个问题有人？我怎么能这样做的双击远程扩大屏幕？
Anybody encountered this problem already? How could I do a double tap to expand the screen remotely?
感谢您的时间！
推荐答案
最后我得到了它。首先我录了双击事件，并将其存储到一个二进制文件：
Finally I got it. First I've recorded the double-tap event and stored it into a binary file:
adb shell
cd /sdcard/
cat /dev/input/event_X > doubletap
执行doubletap无论你想它，然后，结束与记录 CTRL + C
该event_X是叫sec_touchscreen事件。
它可以从获得：
The event_X is the event called sec_touchscreen. It can be got from:
adb shell getevent -p
然后，您可以重放与doubletap：
Then, you can replay the doubletap with:
adb shell "cat /sdcard/doubletap > /dev/input/event_X"
在我而言，这是棘手的，因为它没有工作，一旦重播执行，而是两个，如：
In my case, it was tricky because it did not work executing once the replay, but two, like:
adb shell "cat /mnt/sdcard/doubletap > /dev/input/event_X"
adb shell "cat /mnt/sdcard/doubletap > /dev/input/event_X"
