news 来源：原创 2024/9/13 10:47:56

1.显卡能力排查

目前只有 NIVIDIA 支持 ffmpeg 的 gpu加速(AMD貌似也陆续开始支持)。

在下述网站中查找自己的显卡能够支持的编解码格式。https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-newhttps://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new

2.更新显卡驱动 (可选)

3.安装 cuda tool kit

4.安装包含NVIDIA加速组件的ffmpeg

在gyan.dev发布网站中找到并下载 ffmpeg-git-full.7z ，essential版本不包含NVIDIA编解码器组件，不要下载。

Builds - CODEX FFMPEG @ gyan.devhttps://www.gyan.dev/ffmpeg/builds/

5.配置ffmpeg在windows下的环境

略

6.测试是否安装成功
