When multiple devices are present, let the user pick one.

Is your feature request related to a problem? Please describe.
I'm always frustrated when I run scrcpy only to realize I had multiple devices/emulators connected and then need to copy the serial of one to connect to the device of my choice.

Describe the solution you'd like
Instead of yielding an error, output the list of devices with each device prefixed by a number and then have scrcpy await user input for which device to use:

> scrcpy 
Multiple (3) ADB devices:
1) (usb)  QZ125F6WA1                      device  XQ_BQ52
2) (usb)  emulator-5554                   device  sdk_google_atv_x86
3) (usb)  emulator-5555                   device  sdk_google_atv_x86
Which device would you like to use (0 to exit)? 2

The copy could perhaps be a bit better.

Describe alternatives you've considered
An alternate solution would perhaps be if I wrote my own script which wraps the scrcpy tool with logic based on the scrcpy output, but that could likely break at any time.

Instead of yielding an error, output the list of devices with each device prefixed by a number and then have scrcpy` await user input for which device to use:

I already considered that, but scrcpy could not rely on user input, the user may start it without a console (that's quite common). And even when a console is available, it may be started from a script which does not expect it to wait.

#3005 added -d and -e to select USB and TCP/IP devices. But contrary to adb, an emulator is considered as an USB device. This is a bug, I'll fix it in the next release.

In your specific case, that would allow to call scrcpy -d to select the real device.

Fixed by #3140.

Thanks for taking the time to reply, and that you already had given it some thought :) Now that I understand better the reasons for not implementing a feature like this, feel free to close this.

I'm happy I discovered something else totally unintentionally 😅

What I've seen other libraries do in this case is that you pass an argument to the command, such as -i which would make it "interactable". So if you don't pass -i nothing is changed, it will throw an error just like before, but if you pass -i it will wait for user input if necessary.
