Find export PATH, modify it and add a line

export PATH="$PATH:/usr/local/ffmpeg/bin"

Load the configuration to take effect immediately

source /etc/profile

Test whether the environment variable is set successfully

ffmpeg -version

If the following interface appears, it means that there is an error in the environment reference library

The reason is that the lib directory is not loaded into the link to the system library. The system ld directory list is in /etc/ld.so.conf. Open the file and you will find that it references all of the following /etc/ld.so.conf.d/ .conf file, we only need to create a file and write the lib path

vim /etc/ld.so.conf.d/ffmpeg.conf

Add to the file

/usr/local/ffmpeg/lib

Load the configuration to take effect immediately

ldconfig

Test again whether the environment variable is set successfully

ffmpeg -version
