一、环境介绍
开发板：树莓派4B
操作方式：windows远程桌面连接
远程桌面连接参考这里：https://blog.csdn.net/xiaolong1126626497/article/details/106099194
二、编译安装X264
下面一切都在树莓派4B上操作，下面步骤里下载各种安装包之后(下载通过树莓派4B自带的谷歌浏览器下载)，再将安装包移动
到U盘里进行编译的，主要是树莓派4B本身空间不大。
2.1 编译安装NASM
下载NASM库: http://distfiles.macports.org/nasm/
pi@raspberrypi:/media/pi/DS小龙哥/work $ mv /home/pi/Downloads/nasm-2.14.02.tar.bz2 ./ pi@raspberrypi:/media/pi/DS小龙哥/work $ tar xvf nasm-2.14.02.tar.bz2 pi@raspberrypi:/media/pi/DS小龙哥/work $ cd nasm-2.14.02/ pi@raspberrypi:/media/pi/DS小龙哥/work/nasm-2.14.02 $ ./configure pi@raspberrypi:/media/pi/DS小龙哥/work/nasm-2.14.02 $ make pi@raspberrypi:/media/pi/DS小龙哥/work/nasm-2.14.02 $ sudo make install
2.2 下载编译X264
下载地址: https://www.videolan.org/developers/x264.html
pi@raspberrypi:/media/pi/DS小龙哥/work $ mv /home/pi/Downloads/x264-master.tar.bz2 ./ pi@raspberrypi:/media/pi/DS小龙哥/work $ tar xvf x264-master.tar.bz2 pi@raspberrypi:/media/pi/DS小龙哥/work $ cd x264-master/ pi@raspberrypi:/media/pi/DS小龙哥/work/x264-maste $ ./configure --prefix=$PWD/_install --enable-shared pi@raspberrypi:/media/pi/DS小龙哥/work/x264-master $ make && make install pi@raspberrypi:/media/pi/DS小龙哥/work/x264-master $ sudo cp _install/include /usr/ -rf pi@raspberrypi:/media/pi/DS小龙哥/work/x264-master $ sudo cp _install/lib /usr/ -rf
下面图片是编译之后生成的文件：
2.3 下载编译FFMPEG库
下载地址: http://www.ffmpeg.org/download.html
pi@raspberrypi:/media/pi/DS小龙哥/work $ mv /home/pi/Downloads/ffmpeg-4.2.2.tar.bz2 ./ pi@raspberrypi:/media/pi/DS小龙哥/work $ tar xvf ffmpeg-4.2.2.tar.bz2 pi@raspberrypi:/media/pi/DS小龙哥/work $ cd
