Mochlate · 2017-04-28T03:07:04Z

It is apparent that youtube must have done some update that has messed with the format. Give the devs a few hours to fix it.

eminem136915514 · 2017-04-28T03:14:49Z

i met this problems ,and updated the new released version(4.26),it still doesn't work

Mochlate · 2017-04-28T03:16:06Z

@eminem136915514 this problem did not exists until today, 4/27 how would it be fixed in the 4/26 build?

amoschu · 2017-04-28T03:24:55Z

This may fix it? (I added 'lang_REGION' to the player url regex)

$ diff /usr/lib/python2.7/site-packages/youtube_dl/extractor/youtube.py ~/youtube.py
966c966
<             r'.*?-(?P<id>[a-zA-Z0-9_-]+)(?:/watch_as3|/html5player(?:-new)?|/base)?\.(?P<ext>[a-z]+)$',
---
>             r'.*?-(?P<id>[a-zA-Z0-9_-]+)(?:/[a-z]{2}_[A-Z]{2})?(?:/watch_as3|/html5player(?:-new)?|/base)?\.(?P<ext>[a-z]+)$',

protella · 2017-04-28T03:30:02Z

That seems to have fixed it for me, amoschu. Thx

Wasdsensei · 2017-04-28T05:34:05Z

Any ideas on how one would achieve this in the Windows version? (Or maybe I should just be patient and wait for an update.)

@jianwen03
Edit: /usr/lib/python2.7/site-packages/youtube_dl/extractor/youtube.py
Find the first line in the fix above (line 966)
Replace with the second line. (beginning with the "r")

This fix worked, Thanks @amoschu

@amoschu Thanks dude, easy fast fix.

vedavrat · 2017-04-28T07:06:24Z

"""

I don't have anything named 'site-packages' in /usr/lib/python2.7... help pls?

I have it here:
/usr/local/lib/python2.7/dist-packages/youtube_dl/extractor/youtube.py

Or try to find it:
locate youtube.py

vedavrat · 2017-04-28T07:09:37Z

(#12885 (comment))

@amoschu
Thank you!
Your fix for 'youtube_dl/extractor/youtube.py' file helped !

skeith · 2017-04-28T07:09:54Z

strange, that fix does not work on me

Midaychi · 2017-04-28T07:23:33Z

Can confirm that the fix put forward by amoschu works on windows 10
you go to \AppData\Local\Programs\Python\Python35-32\Lib\site-packages\youtube_dl\extractor
edit youtube.py
line 966
replace the line specified by @amoschu

k-e-keith · 2017-04-28T07:27:34Z

Any way for someone to more clearly explain the process for @amoschu 's fix re: Windows 10?
Total noob here unsure on how to apply it.

Edit: Thanks so much! @amoschu 's fix with @Midaychi 's instructions seems to have done the trick.

rodzky · 2017-04-28T07:43:47Z

Seems like the issue only appears when downloading VEVO videos.
I tried some local videos and the error is not showing.

yan12125 · 2017-04-28T07:49:19Z

I've uploaded a fix based on @amoschu's change. Feel free to leave comments if the problem is still.

This happens to videos in India if that helps

inhahe · 2017-04-28T08:43:25Z

I'm getting the error with every video I try now (I'm listening to random Frosty the Snowman covers). I see some people saying it's only VEVO videos, and I'm not sure what a VEVO video is (a video uploaded by the user VEVO?), but I don't think these are VEVO videos because I don't see VEVO anywhere on the page.

Here's the latest one that I got the error with: https://www.youtube.com/watch?v=MrJWl6QSzNk

mattjis · 2017-04-28T09:37:59Z

@inhahe yeah it's all videos for me too

@yan12125 how can I get youtube-dl to update to the version you just added a commit to?

yan12125 · 2017-04-28T09:43:46Z

how can I get youtube-dl to update to the version you just added a commit to?

A possible way is:

Download https://github.com/rg3/youtube-dl/archive/master.zip and extract it
Open CMD.exe/shell and cd to youtube-dl-master
Install Python from https://www.python.org/ or package managers (apt-get, yum, Homebrew, etc.)
Run python ./youtube_dl/__main__.py (the URL)

erdoukki · 2017-04-28T09:44:57Z

commit e31fed9
applyed locally this fix resolved the issue.

Thanks.

navidR · 2017-04-28T09:46:58Z

How much it would take to become available from pip3 ?

yan12125 · 2017-04-28T09:49:22Z

How much it would take to become available from pip3 ?

If you have git, you can use pip install --upgrade git+https://github.com/rg3/youtube-dl to fetch the latest commit. Otherwise you'll need to wait until the release manager @dstftw has spare time.

irukukagika · 2017-04-28T09:53:51Z

The fix worked. For those who have nothing under /usr/lib/python2.7/site-packages/ check in
/usr/lib/python2.7/dist-packages/ - Python 2.7
/usr/lib/python3.5/site-packages/ - Python 3.5

inhahe · 2017-04-28T09:57:34Z

@irukukagika Mine was in /usr/local/lib/python2.7/site-packages. Forgive my linux n00bness if this is somehow a dumb comment. =)

SuchKnife · 2017-04-28T10:18:57Z

I still dont get it what to do, can someone please give me the full steps what to do? I've tried to go into YouTube.py , then edit with nodepat++, went to line 966, replaced every player url or something for lang_REGION , then I tried the bot, but still nothing works.

arno01 · 2017-04-28T10:23:37Z

@SuchKnife just use the latest youtube-dl from the git master branch:

virtualenv ~/.venv/youtube-dl
. ~/.venv/youtube-dl/bin/activate
pip install --upgrade https://github.com/rg3/youtube-dl/archive/master.zip
alias youtube-dl=$(type -p youtube-dl) | tee -a ~/.bash_aliases
deactivate

There you go! :-)

SuchKnife · 2017-04-28T10:25:16Z

@arno01 Sorry i'm not really that kind of person to know these type of stuff, like what u said. I still have no idea what to do. Sorry! =(

DukeMcAwesome · 2017-04-28T10:27:20Z

@SuchKnife - in the Youtube.py which you accessed, you need to replace the regex on line 966 with
r'.*?-(?P<id>[a-zA-Z0-9_-]+)(?:/[a-z]{2}_[A-Z]{2})?(?:/watch_as3|/html5player(?:-new)?|/base)?\.(?P<ext>[a-z]+)$'

You don't need to change anything else.

SuchKnife · 2017-04-28T10:33:29Z

@DukeMcAwesome Thank you, It's fixed. Thanks everyone who helped <3
