ADB录制视频Android视频录制命令screenrecord在Android 4.4（Kitkat - API level 19）上集成了⼀个⽐较好⽤的视频(.mp4格式)录制功能 –screenrecordscreenrecord。使⽤⽅法1. 基本⽤法$ adb shell screenrecord /sdcard/4/sdcard/4为视频录制⽂件路径/sdcard/4录制默认分辨率，默认4Mbps，默认180s的视频，保存到sdcard上名为42. 旋转(参数：–rotate)$ adb shell screenrecord --rotate /sdcard/4旋转90度3. 指定分辨率(参数：–size)$adb shell screenrecord --size 112x112 /sdcard/4分辨率为112x112,建议不要指定分辨率，使⽤默认分辨率效果最佳;注意，分辨率不是完全可以随意定制的，⽐如在我⼿机上录制100x100的会提⽰错误：The max width/height supported by codec is1920x1088100x100is not supported by codec, suggest to set it as112x1124. 指定⽐特率(参数：–bit-rate)$adb shell screenrecord --bit -rate 8000000 /sdcard/4设置⽐特率为8Mbps，⽐特率越⼤，⽂件越⼤，画⾯越清晰；5. 限制录制时间 （参数: –time-limit）$adb shell screenrecord --time -limit 10 /sdcard/4限制视频录制时间为10s,如果不限制,默认180s6. 导出视频$adb pull /sdcard/47. 注意请关注视频⽂件⽣成⼤⼩，根据⾃⾝情况⽽定；暂不⽀持声⾳；咱时不⽀持模拟器录制(模拟器录制看这⾥)，出现如下提⽰：Unable to get output buffers (err=-38)Encoder failed (err=-38)，可认为是此原因；8. 命令查看adb shell screenrecord --helpUsage: screenrecord [options]Records the device's display to a .mp4 s:--size WIDTHxHEIGHTSet the video size, e.g."1280x720".
