"updating" youtube-dl broke it ...

[Albretch]

youtube-dl was working fine till I "updated" it

first it was downloading more than one file and the video file seemed to play out as an audio one. Then I tried --prefer-ffmpeg and it seemed to have downloaded the video file without audio ...

Why is this happening? How could I fix that problem?

is there an option to downgrade youtube-dl to a working version or download a previous version?
