1. nvidia-codec-headers

#版本 12.0.16cdnv-codec-headers

#更改Makefile文件，指定安装目录

vimMakefile PREFIX=/open_app/user_install

Makefile文件更改后如下所示

make&&makeinstall

2. nvidia-l4t-jetson-multimedia-api

下载包

wgethttps://repo.download.nvidia.cn/jetson/t234/pool/main/n/nvidia-l4t-jetson-multimedia-api/nvidia-l4t-jetson-multimedia-api_35.5.0-20240219203809_arm64.deb

手动解压到你的安装目录

dpkg-deb-xnvidia-l4t-jetson-multimedia-api_35.5.0-20240219203809_arm64.deb /open_app/user_install

检查文件是否确实存在了

ls-l/open_app/user_install/usr/src/jetson_multimedia_api/samples/common/classes/NvBuffer.cpp

4. jetson-ffmpeg

cd~/jetson-ffmpegmkdirbuild&&cdbuild

关键：指定 API 目录为刚才解压出来的路径

cmake..\-DCMAKE_INSTALL_PREFIX=/open_app/user_install\-DJETSON_MULTIMEDIA_API_DIR=/open_app/user_install/usr/src/jetson_multimedia_api

编译并安装

make-j$(nproc)makeinstall

关键：指定 API 目录为刚才解压出来的路径

cmake..\-DCMAKE_INSTALL_PREFIX=/open_app/user_install\-DJETSON_MULTIMEDIA_API_DIR=/open_app/user_install/usr/src/jetson_multimedia_api

编译并安装

make-j$(nproc)makeinstall

3. ffmpeg

版本6.0

1. 批量下载所有的开发包(-dev) 和运行包(包含真实.so文件)

apt-getdownload\libx264-dev libx264-155\libx265-dev libx265-179\libxvidcore-dev libxvidcore4\libvpx-dev libvpx6\libopus-dev libopus0\libmp3lame-dev libmp3lame0\libssl-dev libssl1.1

2. 将当前目录下刚刚下载的所有 .deb 包，批量解压到你的用户目录

forfin*.deb;dodpkg-deb-x"$f"/open_app/user_install;done

3. 修复 xvid 等可能遗漏的“无后缀”软链接 (容错处理)

ln-sf/open_app/user_install/usr/lib/aarch64-linux-gnu/libxvidcore.so.4.3 /open_app/user_install/usr/lib/aarch64-linux-gnu/libxvidcore.so

4. 批量修复所有 .pc 配置文件里的硬编码路径 (解决 pkg-config not found 报错)

find/open_app/user_install-name"*.pc"|xargssed-i's|^prefix=/usr|prefix=/open_app/user_install/usr|g'find/open_app/user_install-name"*.pc"|xargssed-i's|/usr/lib/aarch64-linux-gnu|/open_app/user_install/usr/lib/aarch64-linux-gnu|g'

5. 编译

cdFFmpeg-n6.0

exportPKG_CONFIG_PATH="/open_app/user_install/lib/pkgconfig:/open_app/user_install/usr/lib/aarch64-linux-gnu/pkgconfig:$PKG_CONFIG_PATH"

./configure\--prefix=/open_app/user_install/ffmpeg\--enable-shared\--enable-nvmpi\--enable-nvenc\--enable-cuda\--enable-cuvid\--enable-cuda-nvcc\--enable-libnpp\--enable-nonfree\--enable-gpl\--enable-version3\--enable-libmp3lame\--enable-libvpx\--enable-libopus\--enable-libx264\--enable-libx265\--enable-libxvid\--enable-openssl\--extra-cflags="-I/usr/local/cuda/include -I/open_app/user_install/include -I/open_app/user_install/usr/include"\--extra-ldflags="-L/usr/local/cuda/lib64 -L/open_app/user_install/lib -L/open_app/user_install/usr/lib/aarch64-linux-gnu"\--extra-libs="-lpthread -lm -ldl"

make-j8&&makeinstall

6. 验证

exportLD_LIBRARY_PATH="/open_app/user_install/ffmpeg/lib:/open_app/user_install/lib:/open_app/user_install/usr/lib/aarch64-linux-gnu:$LD_LIBRARY_PATH"
