opencv

1. 先编译了 FFmpeg 60 + rkmpp 硬件解码

• 路径：/usr/local/ffmpeg
• 开启了瑞芯微硬解：--enable-rkmpp
• 这是你视频硬解的核心

2. 备份 + 移走系统旧版 FFmpeg 58

sudo mv /usr/lib/aarch64-linux-gnu/libav* /opt/ffmpeg58_backup/

目的：不让 OpenCV 再找到旧版 58！

3. 移走 pkgconfig 配置文件（最关键一步）

sudo mv /usr/lib/aarch64-linux-gnu/pkgconfig/libav*.pc /opt/ffmpeg58_pc_backup/

4. 告诉系统去哪里找 FFmpeg 60

export PKG_CONFIG_PATH=/usr/local/ffmpeg/lib/pkgconfig:$PKG_CONFIG_PATH
sudo ldconfig

5. 执行 最终版 CMake

强制指定 FFmpeg 60 的路径：

-D FFMPEG_INCLUDE_DIRS=/usr/local/ffmpeg/include
-D FFMPEG_LIBRARIES=/usr/local/ffmpeg/lib/...

6. 编译安装

make -j$(nproc)
sudo make install
