Scrcpy: Fail ffmpeg.so.56 on Ubuntu 20.04

[fbvictorhugo]

• [x] I have read the FAQ.
• [x] I have searched in existing issues.

Environment

• OS: Ubuntu 20.04 64 bits
• scrcpy version: last in apt
• installation method: apt install scrcpy

Describe the bug
When executing the command scrcpy the error occurs as shown below.
_When ubuntu 16.04 worked normal, however in 20.04 with the recent version it doesn't work anymore._

USER:~$ scrcpy 
scrcpy: error while loading shared libraries: libavformat-ffmpeg.so.56: cannot open shared object file: No such file or directory

Because you used a version compiled against libs in an old Ubuntu. You should delete/rebuild.

I delete scrcpy:
sudo apt remove scrcpy

and instal again:
sudo apt install scrcpy

The error remains the same.

But I think apt installed version 1.12
see the terminal:

~$ sudo apt-get install scrcpy

GREAT, that's works !
Deleted the file and did it again.

Thanks!

_but I still think apt is using version 1.12,_

~$ scrcpy

But it's working now!

Yes, for the latest version, I suggest you build from sources :)

Even better, if you could build from the version in #1598, then you could beta-test the future version and give feedbacks :)
