KeyError: 'sig': youtube-dl unable to download Vevo videos due to the "use_cipher_signature" key being set to true.
awojnowski opened this issue · 45 comments
I've created a more appropriately named issue for this, rather than "youtube-dl not working on debian" which is located here: #896
Looks like YouTube has enabled a key named use_cipher_signature
on Vevo videos. This renames the sig
key to s
and hereby renders downloading non-functional.
Here's an example dictionary from the get_video_info
page:

Any idea what type of encryption/cipher they have used on the signature?
To be able to effectively solve this, we need:
- name of the player version and how to get it (HTML5 would probably to easiest)
- Example video, if possible one that's available globally. http://www.youtube.com/watch?v=fBt4VdlZLNI seems to be one, but is blocked (at least in Germany).
-
get_video_info
/url_encoded_fmt_stream_map
- Final URL
From the watch?v=fBt4VdlZLNI

The URL that was playing and the URL that is in the page source have the following differences (playing URL on top, page source on bottom):
cpn=ZAWFmFnq7NPSLdej
keepalive=yes
range=950272-1187839
signature=931EA22157E1871643FA9519676DED253A342B0C.4E95A5DBD2F1F511DCC1209DF56CB77693CE0EAE

So it looks like the URL in the page source doesn't have cpn
, keepalive
, or range
. However, this doesn't make a difference since on my computer, all I have to do is swap the non-working signature for the working one, and the URL will return content.
In conclusion, here's the signature comparison with the working one on top and the non-working one on the bottom:
signature=931EA22157E1871643FA9519676DED253A342B0C.4E95A5DBD2F1F511DCC1209DF56CB77693CE0EAE

ERROR: unable to download video
@mikeygao We released the new version before becoming aware of Youtube's change, and this issue is still marked open, so no, it hasn't been solved yet.
Video available outside of US that appears to suffer from this. Is vevo tagged and throws the KeyError:sig error.
http://www.youtube.com/watch?v=xCUef_NmcP4
Hope it is helpful.
Can also provide output of error, but you seem to have it covered above.
I've some updates about it:
- They can be downloaded!!!: https://github.com/jaimeMF/youtube-dl/tree/youtube_fix_vevo_897. There is an url in the
['args']['dashmpd']
field in theytplayer.config
that points to a xml file that contains the urls, but... - The "bad news" are that the video and the audio have to be downloaded separetely, but they can be joined with ffmepg.
And example of the xml file with the urls is in : https://gist.github.com/jaimeMF/5830327
It seems you can still download the old formats, but you have to decrypt the signature (s=) first.
I found a addon for google chrome which is working with vevo videos.
It decrypts the singatures using a javascript function.
I dont know much about javascript, but I am sure it is possible to extract the method from it.
Here is the relevant file: http://pastebin.com/xtAzQnL2
@strex We need to know where that javascript code comes from, otherwise we can have license issues.
Hmm, yes than we can't use this.
Its from: http://www.overbits.net/chrome/youtube/
I cant find a license on their website.
We can break it by pure analysis with enough samples

Anyone volunteering to take about ten pairs? (Not much time ATM)
Running the original signature noted above through the method named "k" from that JavaScript code (located here: http://pastebin.com/xtAzQnL2) seems to return the reversed signature. Curiously it doesn't seem to work on any other videos though (trying to find why).
It seems there is a bug.
The script only works when the encrypted signature is 87 chars long.
Here's another cracked signature pair:
Original: 7C03C0B9B947D9DCCB27CD2D1144BA8F91B7462B430.8CFE5FA73DDE66DCA33BF9F902E09B160BC42924924

Looks like the signature is less than 87 most of the times on the get_video_info
page whereas it is generally 87 characters long on the actual watch?v=
page.
Edit:
And another pair:

Cracked: 3091D200B71AA36948AC517EC7DB161377428B35.099E8280F1CD26E4F47F5EBED0422C88CAF6AA84
Signatures on the get_video_info
page appear to be uniformly 86 characters in length. Example:
3D7331C0A7A4F82B69824DAD3A5F729FA7A24E6C.E0E928EF47336123334E1627E4FCDF447974B23D3FD3F
From that JavaScript code, here is the method to crack the 87 character signature:
var q = r.substr(44, 40).split("").reverse().join("");
var p = r.substr(3, 40).split("").reverse().join("");
r = q.substr(21, 1) + q.substr(1, 20) + q.substr(0, 1) + q.substr(22, 9) + r.substr(0, 1) + q.substr(32, 8) + r.substr(43, 1) + p
Contrasting that with the method to crack the 86 character signature (which doesn't work right now):
r = r.substr(2, 15) + r.substr(0, 1) + r.substr(18, 23) + r.substr(79, 1) + r.substr(42, 1) + r.substr(43, 36) + r.substr(82, 1) + r.substr(80, 2) + r.substr(41, 1)
Looks like we need an example of a cracked 86 character long signature.
Edit: It appears as if the signature lengths on the get_video_info page actually fluctuate. I've seen 81, 86, and 87. The cracking method doesn't seem to work for it either.
@speedyapocalypse I have also seen sizes of 84, 85 and 91, also the length of the two parts of the key (after and before the points) don't have always the same length. Although the scheme of the signature is the same for all the formats in the same request, but it's useless if we don't know how to decrypt the key.
Anyway, here's the code for getting the key (for sizes 43 and 43 of the subparts only) :
#!/usr/bin/env python
def k(s):
(a,b) = s.split('.')
b = ''.join([b[:8],a[0],b[9:18],b[-4],b[19:39], b[18]])[0:40]
a = a[-40:]
s_dec = '.'.join((a,b))[::-1]
return s_dec
def comp(s_1, s_2):
print(k(s_1))
print(s_2)
print(k(s_1) == s_2)
comp('5AEEAE0EC39677BC65FD9021CCD115F1F2DBD5A59E4.C0B243A3E2DED6769199AF3461781E75122AE135135',

@jaimeMF It looks like they use a different cipher for 87 character long signatures (and presumably all others) when they are returned through the get_video_info
page as opposed to the watch?v=
page. The algorithm you posted works just fine on the actual watch?v=
page whereas it does not work for 87 character long signatures returned through the get_video_info
page.
Looks like we need an example of a working signature from the get_video_info
page and it's encrypted counterpart, unless we just want to use the watch?v=
page to find the URLs.
@speedyapocalypse I know, I have tried to use it with the ones in get_video_info
, but since they are not allways the same size, it's useless. Also, I haven't been able to get a counterpart of the one on get_video_info
, when I run wireshark I don't see any call to that page, do you see it?
Also, do you know how to extract the urls from the watch?v=
page?
@jaimeMF For sure. Here's the idea behind it (I have some written in JavaScript but I presume you'd be looking for Python so I'll let you write/interpret it):
In the page source they have something that looks like so:
"url_encoded_fmt_stream_map":"blablabla"
So basically just use regex or whatnot to find the contents of the url_encoded_fmt_steam_map
. From there, you can split via the ,
character. Then just iterate through these like you would for the get_video_info
page.
@speedyapocalypse That's great, I have been able to use it to download the failing videos!, see https://github.com/jaimeMF/youtube-dl/compare/vevo_fix, if you could test it, I would really thank you (once more :)). Now the videos are downloaded normally, not like in my previous attempt.
Can somebody explain a little bit technology they use? The get_video_info will give encrypted signature. when dl or mplayer try to get the file from server, it has to decrypt signature and send out as &signature=decrypted.
If this is true, we can always find the input and output pair for youtube player or browser which are able to play file by capture all the package on LAN. But what is the point to do encryption if this is true?
I used jaimMF's changes, and things seem to be working: (As an aside; Can someone explain how I could have just fetched his changes? I just copied and pasted into youtube_dl/InfoExtractors.py on master, and then did a make; I didn't see his branch available with git branch -r... (I'm totally a user/n00b. ;p))
(Not A Vevo video) This video doesn't work unpatched; works with YoutubeIE: Detect New Vevo Style Videos:
http://www.youtube.com/watch?v=1ltcDfZMA3U
(Vevo) THIS video works without any patches, and I couldn't begin to understand why:
http://www.youtube.com/watch?v=OhhOU5FUPBE
(Vevo) This video didn't work unpatched, works with jaimeMF's patch:
http://www.youtube.com/watch?v=UxxajLWwzqY
jaimeMF: Thanks for the fix, mate.
@cinereous There's a branch on https://github.com/jaimeMF/youtube-dl called vevo_fix
, you can run
git checkout -b jaimeMF-vevo_fix master
git pull git@github.com:jaimeMF/youtube-dl.git vevo_fix
to get the changes.
@cinereous Thanks for trying it, but does the first video you provide (http://www.youtube.com/watch?v=1ltcDfZMA3U) works with my patch?, I cannot download it, answer it in #900, please.
Seems your patch only for 43 + . + 43 = 87 length sig. But I found with vevo is 81. Does vevo has different s length? Are you working on that now? thank very much for your excellent work.

Without a link to the original video there's little we can do, for the videos I have tried the signature in the video webpage is always of size 87, see this comment above for more info.
I edited the issue title to put the prominent error message in it.
Here’s another one with the same issue, if it helps: http://www.youtube.com/watch?v=iW1W34A-n4I
This is now implemented in youtube-dl. Type
sudo youtube-dl -U
to update.
HI, there,
Is this function being committed to youtube-dl already?

Yes, simply update youtube-dl to the latest version.
There's a remaining issue for which you might have to try to download a
video twice, but they should all work.
I'm still getting an error with this video:

They changed it. Again.
I've fixed it in HEAD, update from git or wait some minutes that I make a release.
@iloveportalz0r Your URL works fien for me in youtube-dl v2013.06.34 (note that -t
is the default by now). Type
sudo youtube-dl -U
to update.
Ah, it works now. Thanks!
Hi, there,
If I use youtube-dl to download, it works fine. But if I use the same
function to decrypt in android, it doesn't work. If I get url and hardcode
to my code in android, it still doesn't work even I know it is not expired
yet. Below is compare two output for url:
Could you please take a look at to see what difference between them? Thanks
very much!

Hi, there,
If I use youtube-dl to download, it works fine. But if I use the same
function to decrypt in android, it doesn't work. If I get url and hardcode
to my code in android, it still doesn't work even I know it is not expired
yet. Below is compare two output for url:Could you please take a look at to see what difference between them?
Thanks very much!Youtube-dl:

@mikeygao Do I understand your message correctly in youtube-dl is working fine, but you have trouble in another application which tries to download from the URLs generated by youtube-dl? If so, then that's probably the problem, as content provider often tie the URL to a specific IP address, session (identified by cookies. see --cookies
), user agent, or even other headers.
You can try reproducing the whole URL generation code in your android app, or just run youtube-dl from your app.
I get that he is trying to emulate YouTube-dl behavior.
Are you sure that you are taking the "s" parameter from the
url_encoded_streams (or something like that) field in the web page
(watch?v=) and decrypting it as we do in _decrypt_signature?

Thanks for replay. Yes, I am doing a youtube like app on android
application to watch video instead of download it. I worked just fine
before vevo signature get encrypted. Now thanks for youtube-dl, it works!
So I write a similar function in java.

I do exactly the same as you said to get s and decrypting it. It looks for
sig and s instead if not found the first. The decrypt function tested
compare to youtube-dl's with input and output is right.

@mikeygao could you possibly submit a new issue to discuss this? You're hijiacking someone else's bug, which isn't nice. I doubt that the majority of the others monitoring this issue want to be spammed with monitoring emails discussing your development problems.
I am sorry about that. That is true. I will do that.

thanks, it works now.
Read some Javascript functions in some Youtube Html pages for encoding the video signature from the "url_encoded_fmt_stream_map" value.
Guess, for a proper and stable solution you will have to parse that huge Javascript file, referenced after tag "js": in the player-config section of the Html and apply a Javascript engine to evaluate the signature.
