Android video recording command screenrecord

Android video recording command screenrecord:

• Screenrecord is a shell command
• Support for Android4.4 (API level 19) or above
• Supported video formats: mp4 restrictions
  • Some devices may not be able to directly record because the resolution is too high. If you encounter such problems, try to specify a lower resolution.
  • Screen rotation is not supported during recording. If the screen is rotated during recording, the screen may be disconnected.
  • When recording a video, the sound will not be recorded and the recording command starts:

    adb shell screenrecord /sdcard/demo.mp4

    Recording mobile phone screen. The video format is mp4, which is stored in the mobile phone SD card. The default recording time is 180 s.

    Limit the recording time:

    Parameter: -- time-limit

    adb shell screenrecord  --time-limit 10 /sdcard/demo.mp4

    Note: The video recording time is limited to 10 s. If not limited, the default value is 180 s.

    Specify the video resolution size:

    Parameter: -- size

    adb shell screenrecord --size 1280*720 /sdcard/demo.mp4

    Note: The Video Recording resolution is 1280*720. If you do not specify the resolution of the default mobile phone, use the size supported by the advanced video encoding (AVC) on the device for the best effect.

    Specifies the video bit rate.

    Parameter: -- bit-rate

    adb shell screenrecord --bit-rate 6000000 /sdcard/demo.mp4

    Note: The specified video bit rate is 6 Mbps. If not specified, the default value is 4 Mbps. You can increase the bit rate to improve the video quality or reduce the bit rate to make the file smaller.
