FFmpeg Download: http://ffmpeg.zeranoe.com/builds/
Download and unzip the FFmpeg folder:
Open any disk you want to install, such as disk d. Create a new folder named "ffmpeg", and copy all the contents of the folder generated in the second step to the "ffmpeg" folder.
Setting environment variables
Right click "my computer - > Properties", then click "advanced system settings", pop up the "system properties" window, and finally click the "environment variables" button:
After clicking the "environment variable" button, pop up the "environment variable" window, find and select the "Path" variable, and click Edit:
Add "; d:\ffmpeg\bin" to the original variable value of "Path" variable (Note:; represents the interval and cannot be omitted; d:\ffmpeg\bin represents the bin folder under the installation Path of FFmpeg). Click "OK" all the way.
Open the command prompt window. Enter the command "FFmpeg – version". If the command prompt window returns the version information of FFmpeg, the installation is successful. You can run FFmpeg in any folder in the command prompt line.
