3 离线安装
编译安装ffmpeg需要gcc环境。将gcc上传到服务器上，以上传到/usr/local/目录下为例：
[root@FFMPEG ~]# rpm -ivh /usr/local/gcc/*.rpm --force warning: /usr/local/gcc/cpp-4.8.5-36.el7_6.2.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:libgcc-4.8.5-36.el7_6.2 ################################# [ 7%] 2:glibc-common-2.17-260.el7_6.5 ################################# [ 14%] …… 10:kernel-headers-3.10.0-957.12.2.el################################# [ 71%] 11:glibc-headers-2.17-260.el7_6.5 ################################# [ 79%] 12:glibc-devel-2.17-260.el7_6.5 ################################# [ 86%] 13:gcc-4.8.5-36.el7_6.2 ################################# [ 93%] 14:gcc-c++-4.8.5-36.el7_6.2 ################################# [100%] [root@FFMPEG ~]# rm -rf /usr/local/gcc/
违规取证视频转码时需要h264编码器。将x264.tar.gz上传到服务器，以上传到/usr/local/目录下为例：
[root@FFMPEG ~]# cd /usr/local/ [root@FFMPEG local]# tar -zxvf x264.tar.gz x264/ x264/x264.c x264/filters/ x264/tools/ x264/configure …… x264/filters/video/select_every.c x264/filters/video/video.h x264/filters/video/fix_vfr_pts.c x264/filters/video/source.c x264/filters/video/cache.c [root@FFMPEG local]# rm -f x264.tar.gz [root@FFMPEG local]# cd x264 [root@FFMPEG x264]# ./configure --enable-shared --enable-static --disable-asm && make && make install platform: X86_64 byte order: little-endian system: LINUX cli: yes libx264: internal …… ln -f -s libx264.so.157 /usr/local/lib/libx264.so install -m 755 libx264.so.157 /usr/local/lib install -d /usr/local/lib install -m 644 libx264.a /usr/local/lib gcc-ranlib /usr/local/lib/libx264.a [root@FFMPEG x264]# ln -s /usr/local/lib/libx264.so /usr/lib/libx264.so [root@FFMPEG x264]# ln -s /usr/local/lib/libx264.so.157 /usr/lib/libx264.so.157 [root@FFMPEG x264]# ldconfig
违规取证视频打时间戳需要freetype支持。将freetype-2.10.0.tar.gz上传到服务器，以上传到/usr/local/目录下为例：
[root@FFMPEG ~]# cd /usr/local/
[root@FFMPEG local]# tar -zxvf freetype-2.10.0.tar.gz
freetype-2.10.0/
freetype-2.10.0/devel/
freetype-2.10.0/devel/ft2build.h

freetype-2.10.0/README.git
[root@FFMPEG local]# rm -f freetype-2.10.0.tar.gz
[root@FFMPEG local]# cd freetype-2.10.0
[root@FFMPEG freetype-2.10.0]# ./configure && make && make install
FreeType build system -- automatic system detection
The following settings are used:
platform unix
……
/usr/local/include/freetype2/freetype/config/ftoption.h
/usr/bin/install -c -m 644 ./builds/unix/freetype2.m4
/usr/local/share/aclocal/freetype2.m4
/usr/bin/install -c -m 644 ./builds/unix/freetype2.pc
/usr/local/lib/pkgconfig/freetype2.pc
添加freetype环境变量：ls
[root@FFMPEG ~]# echo 'export FREETYPE_CFLAGS="-I/usr/local/include/freetype2/freetype/"' >> /etc/profile [root@FFMPEG ~]# echo 'export FREETYPE_LIBS="-L/usr/local/include/freetype2/freetype/ -lfreetype"' >> /etc/profile [root@FFMPEG ~]# echo 'export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/' >> /etc/profile [root@FFMPEG ~]# source /etc/profile
ffmpeg为了提高编译速度使用了汇编指令，需要安装yasm。将yasm-1.3.0.tar.gz上传到服务器，以上传到/usr/local/目录下为例：
[root@FFMPEG ~]# cd /usr/local/ [root@FFMPEG local]# tar -zxvf yasm-1.3.0.tar.gz yasm-1.3.0/ yasm-1.3.0/libyasm/ yasm-1.3.0/libyasm/cmake-module.c yasm-1.3.0/libyasm/bitvect.h yasm-1.3.0/libyasm/section.h …… yasm-1.3.0/config/depcomp yasm-1.3.0/config/mkinstalldirs yasm-1.3.0/config/config.guess yasm-1.3.0/yasm_objfmts.7 yasm-1.3.0/ABOUT-NLS [root@FFMPEG local]# rm -f yasm-1.3.0.tar.gz [root@FFMPEG local]# cd yasm-1.3.0 [root@FFMPEG yasm-1.3.0]# ./configure && make && make install checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /usr/bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes …… /usr/bin/mkdir -p '/usr/local/include' /usr/bin/install -c -m 644 libyasm-stdint.h '/usr/local/include' make[3]: Leaving directory `/usr/local/yasm-1.3.0' make[2]: Leaving directory `/usr/local/yasm-1.3.0' make[1]: Leaving directory `/usr/local/yasm-1.3.0'
将ffmpeg-4.1.3.tar.gz上传到服务器，以上传到/usr/local/目录下为例：
解压缩：
[root@FFMPEG ~]# cd /usr/local/ [root@FFMPEG local]# tar -zxvf ffmpeg-4.1.3.tar.gz ./._ffmpeg-4.1.3 ffmpeg-4.1.3/ ffmpeg-4.1.3/._LICENSE.md ffmpeg-4.1.3/LICENSE.md ffmpeg-4.1.3/._libpostproc …… ffmpeg-4.1.3/libpostproc/postprocess.h ffmpeg-4.1.3/libpostproc/._postprocess_template.c ffmpeg-4.1.3/libpostproc/postprocess_template.c ffmpeg-4.1.3/libpostproc/._libpostproc.v ffmpeg-4.1.3/libpostproc/libpostproc.v [root@FFMPEG local]# rm -f ffmpeg-4.1.3.tar.gz
进入ffmpeg目录，编译安装：
[root@FFMPEG local]# cd ffmpeg-4.1.3 [root@FFMPEG ffmpeg-4.1.3]# ./configure --enable-libfreetype --enable-libx264 --enable-gpl install prefix /usr/local source path .
