RK3588 平台一直无法读取视频
问题描述:
我这边用的是rk3588的核心板，刷的固件里面有opencv 4.5.5， 系统是ubuntu 20.04 LTS版本， 使用cv::VideoCapture无法读取mp4或其他视频，每次读取后isOpened()都是 false;
硬件是rk3588对应的开发板
以下编译安装直接在开发板上进行，不是在宿主机用交叉编译链编译安装的。
opencv 安装
下载 opencv4.5.5.zip， 解压后，在源代码目录新建 build 目录，进入 build 目录；
确保安装了相关依赖
确保安装了相关依赖
确保安装了相关依赖
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev liblapacke-dev
sudo apt-get install libxvidcore-dev libx264-dev
sudo apt-get install libatlas-base-dev gfortran
sudo apt-get install -f ffmpeg # show video
如果 libjasper 安装失败，请往下翻
cd opencv4.5.5
mkdir build && cd build

popd安装 libjasper 或许确认这个就可以了
大意了，一开始安装的时候，没有太在意这个库，所以一直重新编都没有管这个库；
所以在安装 opencv 的时候一定要按照步骤来，否则要找很久的问题。
如果上述opencv重新编译安装还是出现无法读取视频的问题，请确保每个依赖库都已经成功安装。
我相信很多人还是无法读取视频，那么就确认这个库吧。
sudo apt install libjasper1 libjasper-dev
执行上述命令会报错。那怎么办呢？修改 /etc/apt/source.list
sudo cp /etc/apt/source.list /etc/apt/source.list.bak
sudo gedit /etc/apt/source.list

NOTE: 以下过程是试错过程，不一定是必要过程，如果上述过程能解决问题，下面就不用管了。
ffmpeg 重新安装
这里为什么要重新安装 ffmpeg ？ 翻阅了很多博客，说要重新安装 ffmpeg.
但是这里也不一定需要重新安装，重新安装肯定没问题。ffmpeg 版本不要安装太高，因为接口变换较大，可能 opencv 4.5.5 不兼容，我这里试过好几个版本( ffmpeg 6.0, ffmpeg 5.0.3, ffmpeg 4.4.4)，在重新编译opencv时都编译失败。 ffmpeg 4.2.9 可以成功。
Download FFmpeg
ffmpeg-4.2.9
