风流不在谈锋胜，袖手无言味最长。这篇文章主要讲述android shell命令screenrecord和uptime相关的知识，希望能为你提供帮助。
1.使用uptime查看开机时间
130|[email
protected]:/ $ 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
|
1
2 |
// 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
$adb shell screenrecord /sdcard/FILENAME.mp4 |
(2). 指定分辨率(参数：--size)
|
1
2 |
// 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
$adb shell screenrecord --size 112x112 /sdcard/FILENAME.mp4 |
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：
|
1
2
3
4 |
// 100x100不支持，建议设为112x112
$adb shell screenrecord --size 100x100 /sdcard/FILENAME.mp4
The max width/height supported by codec is 1920x1088
100x100 is not supported by codec, suggest to set it as 112x112 |
(3). 指定比特率(参数：--bit-rate)
|
1
2 |
// 设置比特率为8Mbps，比特率越大，文件越大，画面越清晰
$adb shell screenrecord --bit-rate 8000000 /sdcard/FILENAME.mp4 |
【android shell命令screenrecord和uptime】(4). 旋转(参数：--rotate)
|
1
2 |
// 旋转90度
$adb shell screenrecord --rotate /sdcard/FILENAME.mp4 |
