Recording the display of devices running Android 4.4 (API level 19) and higher:
adb shell screenrecord [options] <filename>
adb shell screenrecord /sdcard/demo.mp4(press Ctrl-C to stop recording)
Download the file from the device:
adb pull /sdcard/demo.mp4Note: Stop the screen recording by pressing Ctrl-C, otherwise the recording stops automatically at three minutes or the time limit set by --time-limit.
adb shell screenrecord --size <WIDTHxHEIGHT>Sets the video size: 1280x720. The default value is the device’s native display resolution (if supported), 1280x720 if not. For best results, use a size supported by your device’s Advanced Video Coding (AVC) encoder.
—adb shell screenrecord --bit-rate <RATE>
Sets the video bit rate for the video, in megabits per second. The default value is 4Mbps. You can increase the bit rate to improve video quality, but doing so results in larger movie files. The following example sets the recording bit rate to 5Mbps:
adb shell screenrecord --bit-rate 5000000 /sdcard/demo.mp4—adb shell screenrecord --time-limit <TIME>
Sets the maximum recording time, in seconds. The default and maximum value is 180 (3 minutes).
—adb shell screenrecord --rotate
Rotates the output 90 degrees. This feature is experimental.
—adb shell screenrecord --verbose
Displays log information on the command-line screen. If you do not set this option, the utility does not display any information while running.
Note: This might not work on some devices.
