**1.使用uptime查看开机时间**

130|shell@HWPLK:/ $ uptime  
up time: 00:12:32, idle time: 01:28:59, sleep time: 00:00:00  
**2.使用screenrecord录制屏幕**

`$ adb shell screenrecord --help`

`Usage: screenrecord [options] <filename>`

`Records the device's display to a .mp4 file.`

`Options:`

`--size WIDTHxHEIGHT`

`    ` `Set the video size, e.g.` `"1280x720"` `.  Default is the device's main`

`    ` `display resolution (` `if` `supported), 1280x720` `if` `not.  For best results,`

`    ` `use` `a size supported by the AVC encoder.`

`--bit-rate RATE`

`    ` `Set the video bit rate, in megabits per second.  Default 4Mbps.`

`--` `time` `-limit TIME`

`    ` `Set the maximum recording` `time` `, in seconds.  Default / maximum is 180.`

`--rotate`

`    ` `Rotate the output 90 degrees.`

`--verbose`

`    ` `Display interesting information on stdout.`

`--help`

`    ` `Show this message.`

`Recording continues` `until` `Ctrl-C is hit or the` `time` `limit is reached.`

**screenrecord使用举例**  
(1). 基本使用

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div> 
    <div>
      2 
    </div> </td> 
   <td> 
    <div> 
     <div> 
      <code>// 录制默认分辨率，默认4Mbps，默认180s的视频，保存到sdcard上名为FILENAME.mp4</code> 
     </div> 
     <div> 
      <code>$adb shell screenrecord /sdcard/FILENAME.mp4</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

(2). 指定分辨率(参数：--size)

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div> 
    <div>
      2 
    </div> </td> 
   <td> 
    <div> 
     <div> 
      <code>// 分辨率为112x112,建议不要指定分辨率，使用默认分辨率效果最佳</code> 
     </div> 
     <div> 
      <code>$adb shell screenrecord --size 112x112 /sdcard/FILENAME.mp4</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

注意，分辨率不是完全可以随意定制的，比如在我手机上录制100x100的会提示错误：

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div> 
    <div>
      2 
    </div> 
    <div>
      3 
    </div> 
    <div>
      4 
    </div> </td> 
   <td> 
    <div> 
     <div> 
      <code>// 100x100不支持，建议设为112x112</code> 
     </div> 
     <div> 
      <code>$adb shell screenrecord --size 100x100 /sdcard/FILENAME.mp4</code> 
     </div> 
     <div> 
      <code>The max width/height supported by codec is 1920x1088</code> 
     </div> 
     <div> 
      <code>100x100 is not supported by codec, suggest to set it as 112x112</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

(3). 指定比特率(参数：--bit-rate)

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div> 
    <div>
      2 
    </div> </td> 
   <td> 
    <div> 
     <div> 
      <code>// 设置比特率为8Mbps，比特率越大，文件越大，画面越清晰</code> 
     </div> 
     <div> 
      <code>$adb shell screenrecord --bit-rate </code> 
      <code>8000000</code> 
      <code>/sdcard/FILENAME.mp4</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>

(4). 旋转(参数：--rotate)

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div>
      1 
    </div> 
    <div>
      2 
    </div> </td> 
   <td> 
    <div> 
     <div> 
      <code>// 旋转90度</code> 
     </div> 
     <div> 
      <code>$adb shell screenrecord --rotate /sdcard/FILENAME.mp3</code> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>
