To set a path in the Command Prompt, you can use the set command. For example, to temporarily add a directory to your PATH variable, you can type set PATH=%PATH%;C:\Your\Directory.

How do you run ffmpeg in command prompt?

You run it the same way you do with a terminal shell in systems that are supported by FFMPEG. For syntax, the program will tell you if you use the --help option or check the man pages [Linux]/wiki/manual available online.

The general stuff you need to know is the -i option, the -b, -r, and -c, -vn, and -anoptions.

  • The -i option specifies your input file(s). There fore you can place more than one.
  • The -b and -r options specifies bitrate and sample rate. You add a :a or a :v after the -b option to specify which stream you want to specify the bitrate (-b:a for audio and -b:v for video). The value you specify is in bits/second (bitrate) and in hertz for sample rate. Of course current versions allow you to use letter multipliers as well (e.g. ffmpeg -i music.aac -c:a libmp3lame -b:a 320k music.mp3 converts a AAC file music.aac into a 320Kbps CBR [constant bitrate] MP3 file with an implementation of the LAME codec.
  • The -c option is pretty much set up the same way as -b, -c:a for audio [older versions use -acodec] and -c:v for video [older versions use -vcodec]. But the -c option specifies which codec you wish to use (to find out what codecs you can use for your particular build, run ffmpeg --codecs).
  • The last two are usually only useful for videos. The -anoption is generally used for cutting out the audio track for the given video input. Likewise, you can use the -vn option to extract the audio track from the video.

If you're having trouble, there is an okay graphical front-end for FFMPEG called WinFF.
