Python yt-dlp and ffmpeg error "merging of multiple formats but ffmpeg is not installed"

I am using the latest version of yt-dlp with Python 3.9.

I am trying to download a youtube video in mp4 format with outputname as the youtubeid.mp4 and with best resolution not more than 4K.

This is my Python code:

ytid = '4cDqaLxrt6Q'
url = 'https://www.youtube.com/watch?v='+ytid
output_filename = ytid+".mp4"
    
with YoutubeDL({'format': 'bestvideo[height<=?4K]+bestaudio/best', 'output': output_filename}) as ydl:
    ydl.download(url)`#TODO debug FFmpeg and check if outputname is ok

I expected to have an .mp4 file in my current working directory.

Then I installed the latest version of FFmpeg from ffmpeg-master-latest-win64-gpl.zip and put ffmpeg.exe, ffplay.exe and ffprobe.exe in Scripts python folder (where yt-dlp.exe is). I also installed ffmpeg using pip install.

The Traceback is:

If you are using conda as your Python package manager, you can install ffmpeg in the virtual environment.

Note that the conda method is different from the pip method you mentioned.

(base) C:\Users\user> conda install ffmpeg

See: https://stackoverflow.com/a/75270671/22124527

I have installed last release of FFmpeg from ffmpeg-master-latest-win64-gpl.zip and put ffmpeg.exe , ffplay.exe and ffprobe.exe in Scripts python folder.

"Put .exe in the same python script folder" does not implies "add .exe in the system path that python can find". You can try:

import sys
sys.path.append('/path/to/your/exe/file/location')

You have two ways:

  1. As a workaround, check your system path in Powershell, running: $Env:Path
    Put all three executables ff* in one of the listed paths.
  2. Best way, put all three executables in a folder of your choice and then add that path in Windows env PATH. How to do that depends on your Windows version; check Settings, search in for environment variables.
