Usage: screenrecord [options] <filename>

Android screenrecord v1.2.  Records the device's display to a .mp4 file.

Options:

--size WIDTHxHEIGHT

    Set the video size, e.g. "1280x720".  Default is the device's main

    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 bits per second.  Value may be specified as

    bits or megabits, e.g. '4000000' is equivalent to '4M'.  Default 4Mbps.

--bugreport

    Add additional information, such as a timestamp overlay, that is helpful

    in videos captured to illustrate bugs.

--time-limit TIME

    Set the maximum recording time, in seconds.  Default / maximum is 180.

--verbose

    Display interesting information on stdout.

--help

    Show this message.

Recording continues until Ctrl-C is hit or the time limit is reached.
