Scrcpy crash if target device doesn't have clipboard service

[auzeonfung]

Hi there!

I'm using scrcpy to control my Android based speaker which is without a screen.
It runs a deeply customized Android system and version is 5.1.1.

It was able to successfully connect and control it with the mouse and keyboard before scrcpy upgrade to version 1.14.

It's possible to connect the same device successfully using an older version of scrcpy.

Would it be a good idea to add an option to allow users to ignore this error? 😁

Ref: #1440

[auzeonfung]

Yes, I'm experiencing a similar situation to #1440 .
I can't use the copy function, but I can still at least control my device using the mouse and keyboard by using older version but the latest version can't...
I know it's annoying, but would you consider adding an option to dodge this issue? (--ignore-errors or something like that)? Thank you!

[rom1v]

Could you try the clipboard_manager branch, please?

[auzeonfung]

Thank you very much! clipboard_manager branch works very well.
Also when I tried to bulid the server from source code myself I found the documentation to be a bit out of date, I'll submit a pr later to improve it.
Thanks for all you do!
