Expose device serial as an optional argument
Expose device serial as an optional argument

The device serial was provided as a positional argument:

    scrcpy 0123456789abcdef

Instead, expose it as an optional argument, -s or --serial:

    scrcpy -s 0123456789abcdef

This avoids inconsistency between platforms when the positional
argument is passed before the options (which is undefined).
