Hello

I managed to find the PSSH and the license link, but when generating the key it is returning an error (Code 500).

Can you generate a key and decrypt normally for this link?

Obs: The first few minutes of the video is not encrypted.


Who can help me thank you.

Were you able to decrypt with the information they passed you?

What tools are you using? Youku requires custom script and will not work with sites likes cdrm-project or getwvkeys.

--key d772ba1a18640de9bd6d733e22c3c025:0f0a8ddc6082e473bd35b011fa1203f9

I'm using the EME script to get PSSH and firefox to find that license link I put in the above post.

To generate the key I use a cdm with the WKS-KEYS tool.

I don't know if the PSSH and License Link are right or wrong.

If you can help me I would be grateful

maybe you didn't understand the words of stabbedbybrick: the question isn't right pssh or lic url, but need custom script to get your key ...

Thanks.

In this case I am using the WKS-KEYS tool

[lomero]

... and for WKS-KEYS tool need custom script

does not work with l3.py

Thanks

I would like to learn about the script, I don't want to depend on others to generate the keys.
I have other videos to decrypt, this was just an example I gave to learn about.

If you can direct me where I might be learning about it I would be very grateful.

[stabbedbybrick]

I don't know how to write a script, can you guide me

If you can help me I would be grateful

In order to write a functioning script, you'd need to learn Python. At least if you're using Pywidevine. And that is completely up to you. I can, however, give you some pointers.

Youku, and many other services, send and request information as JSON objects. If you look at the sticky post by A_n_g_e_l_a where she writes about this very thing, you'll see examples of what that might look like if you want to use WKS. You parse the data, generate your challenge, b64encode it, and insert it at the proper place. In many cases, the data is already in JSON, but in youku's case it comes as a series of key:value pairs. So you need to first parse it into JSON, and then insert your challenge at the proper dictionary key, which in this case is fittingly named ["licenseRequest"]. And then you send the request to the license server.

And then you have to do the same thing for the response. It's generally a good idea to print out the steps along the way to see what's happening.

And yes, your PSSH and license url are both correct.

Thank you so much stabbedbybrick, I will try to understand better. Thanks again for the valuable tips.

[CrymanChen]

I agree with @stabbedbybrick, in fact he has explained much of it.
You need some python knowledge to create a customized script for Youku.

i used your method to download files from youkutv. but it seem like key doesn't work anymore and video still encrypted
any help please

[CrymanChen]

Then send the URL of the video you want to download, only in this way can we help you get the keys.
Otherwise are you waiting for me to sort everything done for you?

i have to download videos for everyday . it would be great if you could sort everything for me.
i will buy u a coffee ^_^. because i really need to know how to download from youku.
i can use custom script . but to create the custom script i have zero knowledge of python.
