前言：我本地使用的ubuntu系统版本是20.04，但是我现在需要更新的版本。所以，我就按照以下步骤安装最新版本的scrcpy!
参考：https://gitcode.com/gh_mirrors/sc/scrcpy/blob/master/doc/linux.md
bash
# Step1：安装必要的依赖
$ 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 \
libswresample-dev libusb-1.0-0 libusb-1.0-0-dev
# Step2：从github上下载代码
$ git clone https://github.com/Genymobile/scrcpy
$ cd scrcpy #进入到代码路径为了编译通过，需要修改部分代码：
bash
$ git diff
diff --git a/app/src/decoder.c b/app/src/decoder.c
