Screenrecord Use Example
(1). Basic use

12	// 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). Specify Resolution (parameter:--size)

12	// 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

Note that the resolution is not completely customizable, such as recording 100x100 on my phone will prompt error:

1234	// 100x100不支持，建议设为112x112$adb shell screenrecord --size 100x100 /sdcard/FILENAME.mp4The max width/height supported by codec is 1920x1088100x100 is not supported by codec, suggest to set it as 112x112

(3). Specify bit rate (parameter:--bit-rate)

12	// 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

(4). Rotation (parameter:--rotate)

12	// 旋转90度$adb shell screenrecord --rotate /sdcard/FILENAME.mp4
