• Build Type: You'll usually find static, shared, and dev builds. For most users, the static build is the easiest to use because it contains all the necessary libraries in a single package. Shared builds require you to install additional DLLs, which can be a bit more complex. Dev builds are for developers who want to work with the latest code.

3. Download and Extract

Once you've chosen the right build, download the ZIP file. After downloading, extract the contents to a folder on your computer. A good spot is C:\Program Files\FFmpeg, but you can choose any location you prefer.

4. Set Up Environment Variables

This is a crucial step! To use FFmpeg from the command line, you need to add it to your system's PATH environment variable. Here's how:

1. Find the FFmpeg bin folder: Inside the extracted folder, you'll find a bin folder. This is where the FFmpeg executable (ffmpeg.exe) is located.
2. Copy the path: Copy the full path to this bin folder. For example, C:\Program Files\FFmpeg\bin.
3. Edit environment variables:
   • Search for "environment variables" in the Windows search bar and select "Edit the system environment variables."
   • Click on "Environment Variables..." button.
   • In the "System variables" section, find the Path variable, select it, and click "Edit..."
   • Click "New" and paste the path you copied earlier.
   • Click "OK" on all the windows to save the changes.

5. Verify the Installation

To make sure everything is set up correctly, open a command prompt (search for "cmd" in the Windows search bar) and type ffmpeg -version. If FFmpeg is installed correctly, you'll see the FFmpeg version information displayed. If not, double-check your environment variables setup.

This command adjusts the brightness and contrast of the video.

2. Audio Filtering

Similarly, FFmpeg offers a wide range of audio filters that you can use to enhance your audio. You can apply filters to adjust volume, remove noise, add reverb, and more.

ffmpeg -i input.mp4 -af volume=5dB output.mp4

This command increases the volume of the audio by 5 decibels.

3. Streaming

FFmpeg can be used to stream video and audio over the internet. This is useful for creating live broadcasts or setting up your own streaming server.

ffmpeg -i input.mp4 -f flv rtmp://your-streaming-server/live/stream

This command streams the video to an RTMP server.

4. Complex Filtergraphs

For more complex tasks, you can create filtergraphs that combine multiple filters into a single pipeline. This allows you to perform sophisticated video and audio processing.

ffmpeg -i input.mp4 -vf "split[main][tmp];[tmp]crop=iw:ih/2:0:0,vflip[flip];[main][flip]overlay=0:H/2" output.mp4

This command splits the video, crops the top half, flips it vertically, and overlays it on the bottom half.
