Jetson Nano2GB（TX2\NX\XAVIER）使用ffmpeg进行硬解码配置笔记
到目前为止Jetson设备ffmpeg 硬件编码尚不可用。
l4t3261 jetpack4.6
FFmpeg在Linux平台下开发，但它同样也可以在其它操作系统环境中编译运行，包括Windows、Mac OS X等。这个项目最早由Fabrice Bellard发起，2004年至2015年间由Michael Niedermayer主要负责维护。许多FFmpeg的开发人员都来自MPlayer项目，而且当前FFmpeg也是放在MPlayer项目组的服务器上。项目的名称来自MPEG视频编码标准，前面的"FF"代表"Fast Forward"。 FFmpeg编码库可以使用GPU加速

该过程中最令人担忧的步骤是必须 install
libv4l-dev，我不清楚为什么它没有包含在 jetpack 中，或者如果包含，为什么 configure 找不到该库export LD_LIBRARY_PATH=/usr/local/cuda-10.2/lib64:/home/ljx/ffmpeg-4.2.7/libavdevice:/home/ljx/ffmpeg-4.2.7/libavfilter:/home/ljx/ffmpeg-4.2.7/libavformat:/home/ljx/ffmpeg-4.2.7/libavcodec:/home/ljx/ffmpeg-4.2.7/libavformat:/home/ljx/ffmpeg-4.2.7/libswresample:/home/ljx/ffmpeg-4.2.7/libswscale:/home/ljx/ffmpeg-4.2.7/libavutil:注意你的用户名 ：
最后（这很关键），无论何时运行 ffmpeg，您都需要参考那些最近编译的库。两个选项，在您运行 ffmpeg 时将它们导出到您的
LD_LIBRARY_PATH任何时候，或者将它们复制到您要链接库的任何位置。前者的说明如下（使用 的编译目录~/ffmpeg-4.2.7）：一个好的建议是将其添加到您的 bash 配置文件中以便始终执行此操作:)
