Description

WRITE DESCRIPTION HERE

I have additionally checked with the "padlock" on google chrome's omnibar and it claims newground.com's SSL cert is valid. Since that is enough evidence to conclude that it is probably a problem with youtube-dl, I'm submitting this issue.

[bradenbest]

Uh, don't mind the url. I was gonna make a meme replacing the father's oink with the 'loud nigra' meme.

Discord memes...

--no-check-certificate

Older Python versions have trouble validating certain SSL certificates, so maybe try this with a newer Python.

I'm getting an SSL error that says the certificate has expired:

ericbobrow@Eric-Bobrows-2020-MacBook-Pro ~ % sudo curl -L https://yt-dl.org/downloads/latest/youtube-dl -o /usr/local/bin/youtube-dl
Password:
% Total % Received % Xferd Average Speed Time Time Time Current

curl: (60) SSL certificate problem: certificate has expired
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

I think this is related to the current issue reported by @bradenbest

yeah I already grabbed it via the inspector. Here's the meme if you want to see it for some god forsaken reason: https://cdn.discordapp.com/attachments/399627670327001089/746827448783470623/peppa-pig-loud.mp4

--no-check-certificate

the --no-check-certificate flag works, but my python version is 3.7.9 and it's showing a build date of August 17 2020, so I sincerely doubt my python dist is out of date. The libraries could be a different story, but after my many run-ins with python dependency hell, I'd really rather not touch that.

[s104346]

my python version is 3.7.9

Your debug log shows youtube-dl is running on Python version 3.4.4.
Are you using youtube-dl.exe from the Releases page?

huh, weird. I thought the exe was just a wrapper that links to python dynamically. Yes, I got it from either the website or a github release. Just the exe. I try to avoid full installations on windows since its way of installing programs is very messy.

[EricBobrow]

FYI - when I go to https://yt-dl.org it shows as Not Secure in Chrome, so there appears to be a problem with the SSL certificate.

Possibly related: the update command fails, too.

ytdl -U
ERROR: can't find the current version. Please try again later.

I was gonna say that the update command should also update the version of python that comes with youtube-dl, and then I saw that the command doesn't even work.

[bradenbest]

I renamed my youtube-dl to ytdl.exe since windows' tab completion seems to only be capable of completing paths.

I doubt that's an issue but it if is I can always symlink it.

[EricBobrow]

FYI - I was able to work around the SSL certificate issue by adding the -k option to the curl command.
I was then able to get youtube-dl to work OK on my computer.

I was disappointed however in the speed of file transfer; I have gigabit internet and direct downloads from my personal Vimeo account (or other services) are very fast; with this tool, it took much longer.

I have decided that this will not be the best solution for my needs. I have tested and will use MultCloud to grab videos from my Vimeo account by URL - copying them over into my Dropbox account. I'll have a VA handle this one by one, it will be tedious given that we have over 1,000 videos, but this approach will avoid having to download a terabyte or more at very slow speeds (then re-uploading as well). I will keep youtube-dl in mind for other tasks.

I think you should open a separate issue about those slow download speeds
