2022-06-25 22:13:00 【所向披靡的张大刀】
1.下载指定版本的ffmpeg格式,如本文中采用3.2.4格式 wget http://www.ffmpeg.org/releases/ffmpeg-3.1.tar.gz tar -zxvf ffmpeg-3.1.tar.gz cd ffmpeg-3.1 ./configure make make install
2. 添加进环境变量中:
vi /etc/profile
加入以下内容:
FFMPEG=/usr/local/ffmpeg
PATH加入: $FFMPEG/bin
5.使修改立即生效
source /etc/profile
执行
ffmpeg -version
打印结果
ffmpeg version 2.0
built on Jul 24 2013 09:59:06 with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-3)
configuration: --enable-shared --prefix=/usr/local/ffmpeg
libavutil 52. 38.100 / 52. 38.100
libavcodec 55. 18.102 / 55. 18.102
libavformat 55. 12.100 / 55. 12.100
libavdevice 55. 3.100 / 55. 3.100
libavfilter 3. 79.101 / 3. 79.101
libswscale 2. 3.100 / 2. 3.100
libswresample 0. 17.102 / 0. 17.102
证明已升级成功。如果遇到 ffmpeg: error while loading shared libraries: libavdevice.so.55: cannot open shared object file: No such file or directory 之类的错误,请检查第三步是否做好。
