Warning: Killing the server while running scrcpy

Today, I was trying to operate my mobile phone using my Laptop (Ubuntu 21.10). I found an interesting application that allows me to operate my mobile phone using Ubuntu. The application is known as Scrcpy. I followed all the steps of README.md and installed it using sudo snap install scrcpy. After allowing all the permissions (USB debugging and Security USB debugging) on my android phone, I tried to run it, however, it gives me the following errors:

$ scrcpy

Some information

• Scrcpy was installed using sudo snap install scrcpy

• All permissions are given on my android phone.

• It is the latest Redmi note 10 pro (8GB - 128GB)

• All scrcpy settings are default.

• I am using Ubuntu 21.10 Impish.

Any help is appreciated!

Thanks to pLumo for helping me :)

For anyone who has the same error, the problem was with the unsupported resolution. You need to change the resolution to somewhere near 1024 to get it to work. You can do it by running:

scrcpy -m 1024

You may want to increase or decrease the resolution to adjust for your device.

If you have installed scrcpy using sudo snap install scrcpy, then you will also face a lot of errors!

In this case, start by removing it:

sudo snap remove scrcpy

Now you need to compile it from source or install it using apt.

• Compiling from source:

  As Romain Vimont says in Build.md, you need to follow the following steps to manually compile scrcpy:

  First, you need to install the required packages:

  # for Debian/Ubuntu
  sudo apt install ffmpeg libsdl2-2.0-0 adb wget \ gcc git pkg-config meson ninja-build libsdl2-dev \ libavcodec-dev libavdevice-dev libavformat-dev libavutil-dev \ libusb-1.0-0 libusb-1.0-0-dev

  Then clone the repo and execute the installation script (source):

  git clone
  cd scrcpy
  ./install_release.sh

• Installing from apt:

  As Romain Vimont says in README.md, you need to follow the following steps to install scrcpy using apt:

  On Debian and Ubuntu:

  apt install scrcpy

If you still have issues, then you can start a new issue at scrcpy's GitHub page.
