Error downloading particular (possibly record label associated) videos from YouTube: #3359

It looks like YouTube made some major changes lately because nearly all of the JS downloaders I've tried, including YouTube Center became inoperational in the past few days. Here's the verbose output from youtube-dl: $ youtube-dl https://www.youtube.com/watch?v=KsvKT8vsgF4 --verbose

Interesting. I downloaded between 10-15 other videos before and after this failure, so I don't think YT has 100% overhauled their platform--unless they're being atypically slow in rolling out the feature publicly. This is pure speculation (and hopefully not too much of a digression from the underlying issue), but I'd guess they're starting to implement DRM necessary to protect their new paid subscription service for record labels (the same one that caused a lot of brouhaha for squeezing out the "indies" - http://www.billboard.com/biz/articles/news/indies/6121620/how-youtubes-subscription-terms-will-hurt-indies-no-content-removal). [edit]: I've tested with ~20 videos or so, and the only ones I'm getting errors on are on artist's official pages. |

Same for me tonight: ERROR: Automatic signature extraction failed: Traceback (most recent call last): It seems like we need to do this daily. :( |

Seems like the same thing that happened a little while back, it would stop working, they'd update youtube-dl to fix it, and the next day it would stop working again. It looked like the folks at youtube had given up for quite a while, but I guess they're at it again. |

Thank you for the report. This has been fixed in youtube-dl v2014.07.25. Type @antdude, @seojoohyun YouTube changed the player generation. That exposed a lot of bugs and missing features in our interpreter, but with each change, our interpreter should get better. I expect that this will settle down quite soon. If you want, you can also suggest preemptive changes to our interpreters to make them more robust. |
|
@phihag Thanks! It works on my side now. "If you want, you can also suggest preemptive changes to our interpreters to make them more robust." -- How do we do that? |
|
@phihag Has this been published for pip? I tried updating via pip but I'm still getting these errors |
|
@antdude Simply file a pull request with the changes you suggest. There are just four core developers working on youtube-dl (everyone in their spare time), so we may miss something. |
|
@dwbfox Yes it has. PyPi caches though, so you may have to wait for a while. Can you try again now? |
|
@philhag Oh coding. I don't do that. I do testing though! ;) |
|
@phihag looks like it was indeed cached. Upgrading it again seems to have fixed it. Thanks |
I've been using youtube-dl for a while, and I haven't had any issues an update hasn't fixed. This video in particular seems to present some issues, however. For what it's worth, the Vimeo equivalent of the video downloads correctly.
