在 CentOS 8 上编译支持 CUDA 的 FFmpeg

#FFMepeg #CUDA #CentOS 8

准备工作

在开始之前，请确保已安装 CUDA 工具包。此外，你需要安装以下依赖软件包：

dnf -y install automake autoconf libtool make gcc gcc-c++
dnf --enablerepo=powertools -y install giflib-devel
dnf --enablerepo=powertools -y install libexif-devel
dnf -y install bison pkgconfig glib2-devel gettext make libpng-devel libjpeg-devel libtiff-devel libexif-devel giflib-devel libX11-devel freetype-devel fontconfig-devel cairo-devel fribidi-devel
dnf -y install openssl openssl-devel

注意：根据系统配置的不同，powertools 可能显示为 PowerTools，请根据实际情况替换名称。若需启用 powertools 频道，可运行以下命令：

yum install dnf-plugins-core
yum config-manager --set-enabled powertools
