Do I need FFmpeg for yt-dlp on Windows?

FFmpeg is required for 4K/8K video merges and MP3 audio conversion. Without it, yt-dlp may download video and audio as separate files without merging them.

Where do I download FFmpeg for Windows?

Download from the official FFmpeg site at ffmpeg.org/download.html. Choose a Windows build from gyan.dev or BtbN — both are trusted community maintainers listed on the official page.

Where should I put ffmpeg.exe?

The simplest option: place ffmpeg.exe in the same folder as yt-dlp.exe. yt-dlp detects it automatically.

Setup guide

How to install FFmpeg for yt-dlp on Windows

Four steps, takes under 4 minutes.

Step 01

Download FFmpeg for Windows

Go to ffmpeg.org/download.html and pick a Windows build. Recommended sources: gyan.dev or BtbN — both are listed on the official page.

Step 02

Extract the archive

Extract the .zip or .7z file. Open the extracted folder and navigate to the bin subfolder — you'll find ffmpeg.exe there.

Step 03

Place next to yt-dlp.exe

Copy ffmpeg.exe into the same folder as yt-dlp.exe (e.g. C:\Tools\yt-dlp\). yt-dlp detects it automatically — no configuration needed.

Step 04

Verify it works

Download any video with yt-dlp. You should see [ffmpeg] Merging formats in the output. Or run ffmpeg -version in PowerShell.

Verify & optional PATH

Check FFmpeg is working with yt-dlp

Verify in PowerShell

Check FFmpeg version

ffmpeg -version

Test merge with a real download

yt-dlp -f "bestvideo+bestaudio/best" "URL"

Look for [ffmpeg] Merging formats into in the output.

Optional: add FFmpeg to PATH

Not needed if ffmpeg.exe is next to yt-dlp.exe. But useful if you want FFmpeg available everywhere.

Search Environment Variables in Start
Open Path under User variables
Click New → paste path to ffmpeg\bin
Click OK, restart terminal

Troubleshooting

FFmpeg not found or merge errors — how to fix

"ffmpeg not found" error in yt-dlp

Check that ffmpeg.exe is in the exact same folder as yt-dlp.exe. If you added FFmpeg to PATH, close all terminal windows and reopen PowerShell — PATH changes only take effect in new sessions. Run ffmpeg -version to confirm it's accessible.

Merge failed or output has no audio

Update both yt-dlp (yt-dlp -U) and FFmpeg to the latest version. Outdated FFmpeg builds sometimes fail to merge newer codec formats. Also check that your antivirus is not blocking ffmpeg.exe.

Antivirus flags ffmpeg.exe as a threat

False positive. FFmpeg is a widely used open-source tool. Download only from gyan.dev or BtbN (linked from the official ffmpeg.org page). Add an exception for the file in your antivirus settings if needed.

Do I need ffprobe.exe as well?

ffprobe is optional. yt-dlp can use it for more accurate format detection, but it is not required for basic merges or conversions. If you download the full FFmpeg build, ffprobe.exe is included — just place it next to ffmpeg.exe.

MP3 has no artwork even with FFmpeg installed

Make sure you include --embed-thumbnail --embed-metadata in the yt-dlp command. FFmpeg must be present for these flags to work. See the MP3 guide for the full command.
