Android視頻錄製命令screenrecord
你要知道:
- screenrecord是一個shell命令
- 支持Android4.4(API level 19)以上
- 支持視頻格式: mp4
一些限制
- 某些設備可能無法直接錄製,原因是分辨率太高,如果遇到此類問題,請試着指定較低的分辨率
- 不支持錄製過程中屏幕旋轉,如果錄製過程中旋轉,有可能畫面被切斷
- 錄製視頻的時候聲音不會被錄下來
開始錄製命令:
adb shell screenrecord /sdcard/demo.mp4
說明:錄製手機屏幕,視頻格式爲mp4,存放到手機sd卡里,默認錄製時間爲180s
限制錄製時間:
參數: --time-limit
adb shell screenrecord --time-limit 10 /sdcard/demo.mp4
說明:限制視頻錄製時間爲10s,如果不限制,默認180s
指定視頻分辨率大小:
參數: --size
adb shell screenrecord --size 1280*720 /sdcard/demo.mp4
說明:錄製視頻,分辨率爲1280*720,如果不指定默認使用手機的分辨率,爲獲得最佳效果,請使用設備上的高級視頻編碼(AVC)支持的大小
指定視頻的比特率
參數: --bit-rate
adb shell screenrecord --bit-rate 6000000 /sdcard/demo.mp4
說明:指定視頻的比特率爲6Mbps,如果不指定,默認爲4Mbps. 你可以增加比特率以提高視頻質量或爲了讓文件更小而降低比特率
在命令行顯示log
參數: --verbose
bixiaopeng@bixiaopeng wirelessqa$ adb shell screenrecord --time-limit 10 --verbose /sdcard/demo.mp4

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
