Originally created by @ghost on GitHub (Oct 24, 2017).

So im attempting to download a playlist and when i have download set to True it downloads a file with the name of the video's id but with 'webm' appended to it and with the file extension '.f248' ("6GJO_RpBnEgwebm.f248") another file with the same name is downloaded but with the extension '.f251' ("6GJO_RpBnEgwebm.f251") and finally before returning an error it merges the 2 files into "6GJO_RpBnEgwebm.webm"

I am using this code:

import youtube_dl

ytdl = youtube_dl.YoutubeDL({'outtmpl': '%(id)s%(ext)s'})

ytdl.extract_info("https://www.youtube.com/watch?v=6GJO_RpBnEg&index=1&list=PLZlppmGv_GIKfcd4t6odoAB9a7aUBMBZi", download=True)

And this is the full log from when i run it:
