scrcpy投屏演示效果

 

使用步骤

android设备打开adb调式模式，使用usb数据线连接设备和PC。

鼠标点击解压目录下的scrcpy.exe或者scrcpy-noconsole.exe既可以运行启动投屏界面。

当然直接点击，工具很多功能就无法使用。

如果想使用工具的一些其他功能，建议使用命令行方式加相关参数运行。

命令行操作

scrcpy --help 可以看到工具的命令行用法及界面操作快捷键：

Usage: scrcpy [options]

Options:

    --always-on-top
        Make scrcpy window always on top (above other windows).

    -b, --bit-rate value
        Encode the video at the given bit-rate, expressed in bits/s.
        Unit suffixes are supported: 'K' (x1000) and 'M' (x1000000).
        Default is 8000000.

    --crop width:height:x:y
        Crop the device screen on the server.
        The values are expressed in the device natural orientation
        (typically, portrait for a phone, landscape for a tablet).
        Any --max-size value is computed on the cropped size.

    -f, --fullscreen
        Start in fullscreen.

    -h, --help
        Print this help.

    --max-fps value
        Limit the frame rate of screen capture (only supported on
        devices with Android >= 10).

    -m, --max-size value
        Limit both the width and height of the video to value. The
        other dimension is computed so that the device aspect-ratio
        is preserved.
        Default is 0 (unlimited).

    -n, --no-control
        Disable device control (mirror the device in read-only).

    -N, --no-display
        Do not display device (only when screen recording is
        enabled).

    -p, --port port
        Set the TCP port the client listens on.
        Default is 27183.

    --prefer-text
        Inject alpha characters and space as text events instead of
        key events.
        This avoids issues when combining multiple keys to enter a
        special character, but breaks the expected behavior of alpha
        keys in games (typically WASD).

    --push-target path
        Set the target directory for pushing files to the device by
        drag & drop. It is passed as-is to "adb push".
        Default is "/sdcard/".

    -r, --record file.mp4
        Record screen to file.
        The format is determined by the --record-format option if
        set, or by the file extension (.mp4 or .mkv).

    --record-format format
        Force recording format (either mp4 or mkv).

    --render-expired-frames
        By default, to minimize latency, scrcpy always renders the
        last available decoded frame, and drops any previous ones.
        This flag forces to render all frames, at a cost of a
        possible increased latency.

    -s, --serial serial
        The device serial number. Mandatory only if several devices
        are connected to adb.

    -S, --turn-screen-off
        Turn the device screen off immediately.

    -t, --show-touches
        Enable "show touches" on start, disable on quit.
        It only shows physical touches (not clicks from scrcpy).

    -v, --version
        Print the version of scrcpy.

    --window-borderless
        Disable window decorations (display borderless window).

    --window-title text
        Set a custom window title.

    --window-x value
        Set the initial window horizontal position.
        Default is -1 (automatic).

    --window-y value
        Set the initial window vertical position.
        Default is -1 (automatic).

    --window-width value
        Set the initial window width.
        Default is 0 (automatic).

    --window-height value
        Set the initial window width.
        Default is 0 (automatic).
