Installing FFmpeg on Windows 11

To install the FFmpeg, go to its official website and download the latest version of the installer file. Its name should be something like this:

ffmpeg-2026-04-30-git-cc3ca17127-essentials_build.7z

Extract the downloaded file with 7-Zip. Change the name of the extracted folder to ffmpeg and move the folder to your system's root directory.

To run ffmpeg commands without entering their full path names, you should add C:\ffmpeg\bin folder to the PATH environment variable. The following command will do the trick for you:

setx PATH "%PATH%;C:\ffmpeg\bin"

To verify the installation, try printing the version information of the FFmpeg:

ffmpeg -version

How to increase the volume level of an audio file

Use the volume audio filter. The following command increases the volume of input file by 20 decibels:

ffmpeg -i input.mp3 -filter:a "volume=20dB" output.mp3
  • -i Specifies the input file.
  • -filter:a Applies the following audio filter to the output file.
  • volume= The audio filter.

How to create a sine wave mp3 file

Use the sine source filter as a virtual audio input. The following command generates 5 second mp3 file with a 440 Hz tone:

ffmpeg -f lavfi -i "sine=frequency=440:sample_rate=48000" -t 5 output.mp3
  • -f lavfi Tells FFmpeg to use the libavfilter.
  • -i Usually, specifies an input file. In this specific case, it specifies the sine source filter as a virtual input.
  • frequency=440 Sets the sound tone to 440 Hz.
  • sample_rate=48000 Sets the audio sample rate, measured in Hz.
  • -t Sets the duration of the output file in seconds.

How to convert a WAV file to an MP3 format

Use FFmpeg with some basic options. The following command converts an WAV file to a new stereo MP3 file.

ffmpeg -i input.wav -b:a 128k -ac 2 output.mp3
  • -i Specifies an input file.
  • -b:a Set a bitrate. Common bitrates include 128, 192, and 320, measured in kbps.
  • -ac Sets the number of channels. Setting -ac 2 results in a stereo output.

Creating a single solid color video with an audio track

Use the color source filter as a virtual video input. For example, the following command generate a video with a solid navy color background and an audio track:

ffmpeg -f lavfi -i color=c=navy:s=1920x1080:r=10 -i input.mp3 -c:v libx264 -c:a copy -shortest output.mp4

The breakdown of options follows:

  • -f lavfi Tells FFmpeg to use the libavfilter.
  • -i Specifies the color source filter as a virtual video input.
  • c=navy Sets the color with common color names such as red, green, or blue. You can also use hex codes like #FF0000.
  • s=1920x1080 Specifies the video resolution measured as horizontal x vertical pixels.
  • r=10 Sets the frame rate of the video, measured in frames per second (FPS).
  • Another -i specifies the input audio file.
  • -c:v Specifies the codec for encoding the video stream. libx264 means H.264/MPEG-4 codec.
  • -c:a copy Specifies an audio codec, in general. In this specific case, it tells FFmpeg just to copy the audio stream without encoding it.
  • -shortest Tells FFmpeg to stop processing when the shortest input ends. In other words, it sets the length of output to the length of the shortest input.

Hiding the build-information banner

Add the -hide_banner switch to your ffmpeg command:

ffmpeg -hide_banner -i input.wav output.mp3
  • -hide_banner Suppresses the output of FFmpeg build information and copyright notice on a command startup.

How to close ffplay automatically

By default, ffplay remains open when a media file finishes playing. To close it automatically, use the -autoexit switch:

ffplay -autoexit sample.mp4
