yes, agree python version issue, i now use 3.11.7

Broke for me too on 3.10.8.

[shellcmd]

give windscribe a try, need register a free account, and 10GB band/month, totally enough for make video test. or urbanvpn.

I seem to have found that the problem is that my proxy software does not support cmd command Windows and I may still use a regular vpn to get the US ip

I think I have found the problem Is caused by network problems to 403 because I try to use the curl https://www.nba.com/watch/video/2016-dunk-contest-lavine-vs-gordon-best-ever No response site at all Maybe I need a vps

are you serious? to buy a vps?

Their login functionality was implemented in a good way, which was a nice thing to see. The easy solution was to simply use the browser cookies to skip that. So if you want free videos that need a free account to watch, make one and log in using the Firefox browser (and make sure the browser cookies don't get deleted).

Also, their API was kinda inconsistent in some responses so the script may not work for the rare video once in a while. Regardless, if there are problems, just leave a message here and I may take a look.

Edit: Seems I kinda praised their login functionality a bit too much. Now the script works fully programmatically without needing to check for existing browser cookies. If you have an account just fill in your email and password. If you just want videos without needing a free account, just make the EMAIL and PASSWORD variables empty strings (the script will obviously fail then if you attempt to download account-required videos).

Edit2: I've seen that some users needed a US VPN. So if something fails, I guess try with that.

Hello I have tried to get this script to work but it gives this error:
in get_pssh_info
v_m3u8 = re.findall(r'^v.*?\.m3u8\?.*?$', requests.get(manifest).content.decode(), re.MULTILINE)[-1]
IndexError: list index out of range

I manually retrieved the pssh and I was able to get the key and download but I want the script to not fail.

Try to dump them with KeyDive: https://github.com/hyugogirubato/KeyDive/releases
And no, there's no way to get the KEY part of the kid:key pair without making a license request, so you either need an L3 script with your CDM or an online service like cdrm-project (unless, if you're lucky, you find the key already cached in cdrm-project-like sites).

Btw as Pepe said, use his updated script or if you want to go the manual way for some reason, here's what you need:

#####de364968b3d996c4af2681e8c3098fd9#####Dude, this is really impressive, it seems like witchcraft, there must be some final part of the process going wrong, I can't understand.
This video was just a random one that I took to study key issues without any kind of programming
It really is this video key, it worked amazingly, as I would have liked, I got my own keys, I spent night and night looking for this code, analyzing each browser script, I never got even close to it.

[braquino21]

With all the humility in the world, could you teach me?
sample What is DRM itself, how do you do it or where does it matter, whether there is a way to do it or not, How can I actually make the files evice_client_id_blob e device_private_key If you really need them or not? what would be file WVD_FILE = "./device_wvd_file.wvd" I believe I'm making a mistake by not understanding what each file means

[braquino21]

I installed package KeyDive I reconnected everything again and it still gives me an error

[2nHxWW6GkN1l916N3ayz8HQoi]

what would be file WVD_FILE...

The WVD_FILE is the local path to your cdm in wvd format. What are even these words and how to get one / convert one => read the sticky threads.
After getting one and setting the path, you set your account credentials as well. The email / password in the 2 variables at the start of the script.

You aren't using the updated version. It won't magically edit itself unless you take the latest version.

@2nHxWW6GkN1l916N3ayz8HQoi done, this was very easy but I don't have my own files I even tried to make them I emulated everything, virtual android cell phone, server "FRIDA" I executed "dump_keys" and in the program "ANDROID STUDIO" I accessed "https://bitmovin.com/demos/drm" play video phone virtual but I searched with the computer all morning I couldn't find the directory of the files

[braquino21]

however I am using two files that came within WKS-KEYS google_android_sdk_built_for_x86_v4.1.0-android_b055e439_4464_l3.wvd?

[2nHxWW6GkN1l916N3ayz8HQoi]

however I am using two files that came within WKS-KEYS google_android_sdk_built_for_x86_v4.1.0-android_b055e439_4464_l3.wvd?

I dunno wks-keys so I can't assist you. I did encounter this issue once though with someone else. The wvd generated from a cdm from wks-keys couldn't be used at all but the one you dumped on your own, it could. So I recommend getting your own one. If you can't get one, stick to manual.

[braquino21]

@2nHxWW6GkN1l916N3ayz8HQoi
[Attachment 78433 - Click to enlarge] these errors be related to the WKS-KEYS CDR? Is this how I can get my own CDR to generate keys?

[2nHxWW6GkN1l916N3ayz8HQoi]

these errors be related to the WKS-KEYS CDR?

I don't know what they're related to or what is their cause. What I do know is that after I switched the wvd with something I dumped on my own, it worked.

[braquino21]

I would like to thank everyone here in the group again for their attention and all their help, after brainstorming I managed to generate my own device_client_id_blob and device_private_key files and then I just had to do the conversion to device_wvd_file.wvd format and put them inside the root of pywidevine-master on the first attempt I was rewarded with the my first two keys " but soon after the third attempt the next error occurred
