[larley]

Can't troubleshoot as I'm not home right now. I've also never seen a 412 Error before

First of all, thank you for your help.
After I blocked the second license URL and then Ctrl+R to reload the page. The third 'cenc' appears on the page.

[Attachment 81253 - Click to enlarge]
It was my mistake just now, I should have continued to choose the second license URL.
I have tried again now, Paste the PSSH first then copy the second license URL using 'copy of fetch' and click 'Process'

403 Forbidden now?
Are you able to get a 200 status code if you don't block the license and resend it? (Right Click -> Resend)

Is my screenshot correct?

[larley]

Yes, but I actually don't know why it's not working

Is my screenshot correct?

I saw that the license query was blocked. can you check your settings?

[LZAA]

'Network reguest are not blocked'.

I just made a test for 'one-time only token'.

[zifeng426]

'Network reguest are not blocked'.

If you have found the cause of the problem, could you provide a more detailed description. Thanks a lot.

[mrmaho]

Thanks for this nice tool larley! Works like a charm
With one platform i get this error. It probably need custom scripting?

[larley]

Yes, you send me a PM

Hi all,
this is WidevineFetch, a program that just requires a 'Copy as fetch' input (and an L3 CDM of course) and nothing else.

What it does:
The program will parse the given input, and extract the Request URL, headers and body.
It will locate the license request inside of the JSON (if it's not just bytes), extract the PSSH, generate a new license from that PSSH and replace it.
It will also extract the license from the response, if JSON.
The PSSH has to be entered manually if the service doesn't send the license request (just the first request) when blocking the URL (can be seen on the last service in the demo video).

A demo video is available here (or just on the GitHub page, as well as installation and usage instructions).

Finally, no more custom scripts (mostly).
Hope you like it.

larley ,

He's great
takes care of all your problems,
It is absolutely solution oriented,
He is a creative and stubborn person.
We exchanged countless correspondence, conversations and files for 2-3 days, and he tirelessly tried to solve the problem.

and the problem was solved.

I recommend you to make your necessary solutions with Larley.

because the scipti works 100% fine

Thank you and I appreciate it.

[salimrz]

I wish you continued success, Larley.

[larley]

thanks to both of you

[dxious]

Did the tool work on other sites that you've tried?
If not, then please try to get the keys from the Bitmovin DRM Demo first.

License code 500 is very unlikely to occur on normal use, did you accedentally pick licensing.bitmovin.com? That's a URL that I've seen appearing on some sites before, even though it's not a real license URL. So please make sure that you're copying the currect URL

Thank you for your reply. Now I can use it.

The reason I can't use it is due to my L3 CDM error. Now I have created a new L3 CDM and WidevineFetch. can be used

WidevineFetch Easy to use and hassle-free, thank you for making it.

[senkron24]

waww pretty cool will try it later

Hi guys,

First off all, thank you for the script.

I know I am going to ask a really noob question, but your help will be greatly appreciated.

I am stuck with something stupid, but how do you get this to open:

[Attachment 81326 - Click to enlarge].

I normally just got keys with cmd, but would like to use the GUI. Also, should the CDM be named something specifically and should it be in the CDM folder?

If I run in in cmd, then I get this:

Thanking you in advance,

You probably haven't read the "Requirement" section in the README?

You should upgrade to Python 3.12, the error message makes me believe you run Python 3.8 or Python 3.9.

[larley]

The CDM name doesn't matter

[tjvatikaki]

The CDM name doesn't matter

Thank you. I have install python 3.12 and the program now opens correctly. But it seems there is an issue with my cdm. (I have used this cdm in the passed with other python scripts and it works), but I think I am doing something wrong. When I dumped the cdm, I got 2 files:

"client_id_blob" and "device_private_key". I have copied them to the CDM folder, but I receive an error "no widevine devices detected inside the cdm directory".

Should I keep both? Or which one do I need to use?

Thanking you in advance

It's obvious you didn't read the information page.

Thanks for the reply. I did, it states:
"Place your CDM (as a Widevine Device) inside of the `cdm` folder.".

But which one of the 2 files do I use or do I use both?

use "pywidevine" to create a CDM.

pywidevine create-device -t ANDROID -l 3 -k device_private_key -c device_client_id_blob -o .

[pssh]

Is this tool multi platform or just Windows?

I am trying on Debian 12 with BitMovin website
with license server

regexp:no_auth

but getting ERROR:

Unable to obtain decryption keys, got error code 500: INVALID_LICENSE_CHALLENGE

When pasting the PSSH

AAAAW3Bzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAADsIARIQ62dqu8s0Xpa7z2FmMPGj2hoNd2lkZXZpbmVfdGVzdCIQZmtqM2xqYVNkZmFsa3IzaioCSEQyAA==

I get

Unable to parse fetch string

[larley]

I haven't tried actually
I'll see what I can do

The second error shoudn't occur though. Did you make sure to paste the PSSH, copy the fetch and then click Process?

Hi larley

Thank you again for all your help and detailed explanations. I have managed to get a device.wvd (thanks lomero). I have now tried to get the key from the bitmovin website, but I receive the following error:

Could you please advise what I am doing wrong here?

Thank you in advance.

[larley]

Again, this doesn't look like the right URL.
What to request did you copy from?

I took this license and copy the fetch.
