Bug in VdoCipher schemes

[rgysoft]

Hi, When using VdoCipher scheme and when executing "await js.corsFetch(..)"

[with Firefox] i have this error: "TypeError: tabs[0] is undefined" [with Chrom] i have this error: "TypeError: Cannot read properties of undefined (reading 'id')"

i checked url, headers (before js transformation), payload! all seems to be ok! thank you very mutch

Could you edit popup.js like following and check log output? Also, if you unzipped the updated extension into the same directory, did you reload the extension?

window.corsFetch = (u, m, h, b) => {
    return new Promise((resolve, reject) => {
+       console.log("Debug:"+pageURL)
        chrome.tabs.query({ url:pageURL }, (tabs) => {
            chrome.tabs.sendMessage(tabs[0].id, {type:"FETCH", u:u, m:m, h:h, b:b}, (res) => {
                resolve(res)
            })
        })
    })
}

when i change code to this chrome.tabs.query({}, (tabs) => { and keep only the video tab, I can pass the error, so the problem is in utf8 caracters in url (arabic)

but unfortunately after doing this change the response is {'code': 2011, 'message': 'request unwrapping failed'} :( thank you

I see. Could you check if it works with https://www.vdocipher.com/video-security/ ? If not, confirm if CDM you are using is extracted from a physical device.

same error {'code': 2011, 'message': 'request unwrapping failed'}, yes, CDM extracted from my phone, but probably blocked by vdocipher, I did too many tests before your script, and last error with other script is "{"code":2046,"message":"Authentication failed"}" that's weird all vdocipher video works well on my phone

[FoxRefire]

Hmm, Did you enable License blocking? Right-click --> Enable License blocking If enabled, an error message "Error 6007" should appear and the video will not play. Also, try setting Useragent to Firefox Linux. Someone reported that this worked on Amazon.

If this does not work, try the following:

1. Enable License blocking
2. Insert the line "print(payload)" after line 6 of VdoCipher.py
3. Check the console, you will now get an unconsumed token.
4. Check if the retrieved token can be used with vdochipher-dl

[rgysoft]

I tested that before, tested with unconsumed token (request blocking with fiddler) but always {"code": 2046,"message":"Authentication failed"}", I think my CDM is the problem, I will test with other fresh CDM when possible, thank you very much

Could you send DRM Info screenshot on your phone? https://play.google.com/store/apps/details?id=com.androidfung.drminfo

The screenshot shows a slightly older Android version, so perhaps that is the cause. Can you play the VdoCipher's video from this your phone itself?

Im trying the Vdocipher demo page to test the ext, using a moto c plus(android 7.0) cdm but it doesnt fetch the keys. Theres no error per se, but the ext freezes and does nothing.

Not creating a new issue as this thread effectively highlights this.

Quick notes:

1. vdocipher demo video doesnt play on the moto c plus. It needs an additional zen player to play.
2. There is no problem playing the demo on my much older Samsung galaxy Note 4 Sm-N910 with Android 6.0.1 but I havent rooted(or vis-a-vis dumped cdm)it as that would reset my phone to factory settings.

Hello @FoxRefire Is there any hope that the scheme will be able to work again? Thanks in advance.
