JS Player issue

[srayan]

I am getting the following error, when trying to download certain youtube-videos. I am also post-processing them using ffmpeg, to rip out the audio from the Youtube video. I am running Arch Linux

Here's the command I was using:

youtube-dl -o "%(title)s. %(ext)s" --extract-audio --audio-format "mp3" --audio-quality "160k" youtube-url

Duplicate of #3104. This issue was fixed in c26e9ac, run sudo youtube-dl -U to upgrade.
