FFMPEG系列二:linux下下载编译安装ffmpeg(超详细附采坑完整版)

1、官网下载linux版本的ffmpeg源码包 ffmpeg-4.0.tar.xz

此步骤也可使用git clone下载源码包,本质上是同样的 图片.pngjava

2、使用xftp将源码包ffmpeg-4.0.tar.xz上传至linux主机(直接使用linux命令下载到linux也能够)

3、将上传至/usr/local/ffmpeg的源码包解压

cd /usr/local/ffmpeg
tar xvJf   ffmpeg-4.0.tar.xz

4、 进入解压后目录,输入以下命令/usr/local/ffmpeg为本身指定的安装目录

cd ffmpeg-4.0
./configure --enable-shared --prefix=/usr/local/ffmpeg

报错:gcc is unable to create an executable file C compiler test failed.此错误解决办法查看node

gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
[csy@root@instance-m4tjyg0q ffmpeg-4.0]#

5、解决报错gcc is unable to create an executable file C compiler test failed.以后再次执行以前的命令

cd ffmpeg-4.0
./configure --enable-shared --prefix=/usr/local/ffmpeg

回车以后,可能会等待一段时间,耐心等候linux

6、执行make(编译)

make

此过程有点久,会编译各个库文件git

7、执行make install(安装)

8、安装以后,执行

/usr/local/ffmpeg/installlocation/bin/ffmpeg --versionweb

此时又报错:ffmpeg -bash: ffmpeg: command not found linux下ffmpeg -bash: ffmpeg: command not found解决办法apache

9、解决上述问题以后

再次输入/usr/local/ffmpeg/installlocation/bin/ffmpeg --version 又报错vim

/usr/local/ffmpeg/installlocation/bin/ffmpeg: error while loading shared libraries: libavdevice.so.58: cannot open shared object file: No such file or directorytomcat

提示库文件找不到 修改文件/etc/ld.so.conf 内容增长/usr/local/ffmpeg/lib/ vim /etc/ld.so.conf 输入i才能插入编辑bash

最后文件内容是app

include ld.so.conf.d/*.conf
/usr/local/ffmpeg/lib/

添加以后按esc再:wq保存退出。

再输入ldconfig使修改生效。

这样错误就解决了,再回答第八步输入 /usr/local/ffmpeg/installlocation/bin/ffmpeg --version

可见ffmpeg安装成功,接下来配置环境变量 path(不配置的haul只能每次cd /usr/local/ffmpeg/installlocation/bin/ 才能执行命令)

第十步:配置ffmpeg环境变量

详细查看:[linux下ffmpeg -bash: ffmpeg: command not found及环境变量设置]()

十一步:测试

cd到有gif文件的目录 cd /usr/local/java/apache-tomcat-8.5.24/webapps/it399/src/ffmpeg/temp/gif2video

输入命令 ffmpeg -f gif -i test.gif test.mp4 回车以后输入命令或者xftp客户端查看该目录下文件,可见已经成功将test.gif转成了test.mp4
