step1. Store the downloaded decompressed file in a relatively fixed directory
The following is my path.
Then you will find that there is a folder called bin in the decompressed file. This folder is where our executable files are stored. Add this bin folder to the system environment variable later.
D:\SW_Portable\ffmpeg-set-as_env
step2. Add the bin file to the Windows environment variable
Right click on My Computer -> Properties -> Advanced System Settings -> Environment Variables -> System Variables -> Click Path -> Edit...
