E: 无法定位软件包 pkg-config-libavcodec-dev

这个问题看起来是你在安装软件时缺少了 libavcodec 的开发库，你可以尝试通过运行以下命令来安装它：

sudo apt-get install libavcodec-dev

如果问题仍然存在，你可以尝试更新你的软件源并重新安装：

sudo apt-get update
sudo apt-get install libavcodec-dev

安装opencv软件包

Opencv是一个开源计算机视觉库，提供了许多用于处理图像和视频的函数和算法。以下是在Ubuntu上安装OpenCV的步骤：

1.更新软件包列表：

sudo apt-get update

2.安装OpenCV的依赖项：

sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

3.安装OpenCV的Python支持：

sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

4.下载OpenCV源代码：

git clone https://github.com/opencv/opencv.git

5.创建build目录：

cd opencv

mkdir build

cd build

6.使用cmake构建OpenCV：

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..

7.编译OpenCV：

make -j4

8.安装OpenCV：

sudo make install

9.添加OpenCV的库路径：

sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'

sudo ldconfig

现在您已经成功安装了OpenCV。
