Getting errors while playing a song with my discord.py bot,

• This error hasn't been happening, and i didn't edit so I don't know why now it's happening.

---

So I don't know what the problem is but when i play other songs it works but when i play this song https://www.youtube.com/watch?v=_Yhyp-_hX2s, It just gives me the error below!!!! What is the difference? They're both YouTube videos and it's not a playlist or something, it straight a video.

I'm not going to share my respiratory but it's like this https://github.com/CharmingMother/kurusaki_voice/blob/ddc2628cbb2ebe1fe2987a37fa3733f1316064d4/audio.py and same issue with that too, so IDK

it's not just your program, it seems to be a problem with youtube-dl itself. i tried downloading a video https://www.youtube.com/watch?v=UysJ2Kh35O4 just now and got the same error.

i think it might be a problem on youtube's side, considering the "encodeURIComponent" part of the error. either way, i hope it can be fixed before it causes too many problems.

I had the problem too. I realized it didn't update successfully because I had youtube-dl in /home/user/.local/bin/ and in /usr/local/bin/ and it would only execute the first one. I had to delete it and move the new one there. After updating it worked again.

Hmm... I am having this Signature extraction failed: Traceback error not only from youtube-dl but also from mpv and NewPipe. NewPipe released v0.15 yesterday it works on 0.15 but later version have same error. Also, mpv gives the same error!

My Solution for Mac/Linux & Unix:

Uninstall youtube-dl via your package manager and install the lastest build from the official website. https://rg3.github.io/youtube-dl/download.html

I saw there has been a commit to youtube.py extractor file 3 days ago, but the build version from the apt archive is 2018.10.03, which is quite old at this point. So just download the latest binary from its site.

mpv works too!
