Cannot use it on Windows

[Christian Castelli]

Hi,
I tried to simply download only the audio of a video:

C:\Users\User>ytdl https://www.youtube.com/watch?v=Wbh2Ce4ZfNY -o herbert.mp4 --filter audioonly
No such format found: highest

As far as I know, the q parameter has highest as default value. Do I lack some dependency?

• OS: Windows 10
• Node version: v12.13.1
• ffmpeg: git-2019-11-01-53c21c2
• npm: 6.14.2

it's a bug when using -o with a file extension. will fix soon.
