Seems that extension is still kinda buggy. Hope they fix it. Here's what worked for me without bothering too much. There are 2 directories
- PlayReadyProxy-API-main => the local api
- PlayReadyProxy-main => the extension

Unpack them both. In the local api folder:
- rename the env and config like their git tells you to do
- copy in that folder (near the app.py) the prd file. Mine is called: "your_prd_file.prd"
- then go to config.ini and change

[CDM]
DEVICE_FILE = device/ # DEVICE FILENAME
DEVICE_NAME = # DEVICE NAME

to

[CDM]
DEVICE_FILE = your_prd_file.prd
DEVICE_NAME = your_prd_file.prd

- create the file "APIKEY.json" (double check the right extension, do not create "APIKEY.json.txt"). Then in that file paste this content

[{"apikey":"secret"}]

- start their flask server like their git tells you to do and it runs on

* Running on http://127.0.0.1:1337

Now in the other extension folder.
- go to config folder and open "local.json" . Change

{
    "security_level": "",
    "host": "",
    "secret": "",
    "device_name": ""
}

to

{
    "security_level": "",
    "host": "http://127.0.0.1:1337",
    "secret": "secret",
    "device_name": "your_prd_file.prd"
}

- then install the extension on edge
- open the addon menu, make sure "enabled" is checked. Go to remote cdm > choose config and pick the previously edited "local.json" file.

While testing the addon on
https://reference.dashif.org/dash.js/v4.4.0/samples/drm/playready.html

I had to refresh 2 times to get both set of keys (video+audio) and it worked.

It's a C# implementation. It's not an addon. It even explains you the steps in the readme git section. If you can handle pyplayready, you can handle the C# alternative. If you don't know about scripts, then you can stick only to the addons.

Many thx for this tutorial

No problem

[evangelle]

I had done all step
but It seems not query the api.

[yalgerino]

Hello,

Thanks for this tutorial!
I've done everything correctly, I don't get any error messages, and yet it's not working. Any ideas?

My PlayReady-API -> config.ini :

[CDM]
DEVICE_FILE = device/lg_electronics_inc_lg_webos_tv_msd93xbg_sl3000.prd
DEVICE_NAME = LG

My PlayReady-API-> APIKEY.json :

[
    {
        "username": "test",
        "apikey": "test_99c036381a6736de600f61c07a"
    }
]

My PlayReady -> config -> local.json :

{
    "security_level": "3000",
    "host": "http://127.0.0.1:1337",
    "secret": "test_99c036381a6736de600f61c07a",
    "device_name": "LG"
}

Did I miss something, please?

Thanks in advance

larley the king of video decryption! thank you so much mate for your work. amazing

just little tip: from PR github page on chrome section you write 'download zip'
we have just xpi file, for FF. anyway it's easy to extract all content with wrar or 7zip

loaded extension on chromium browser i get this error 'background.scripts' requires manifest version of 2 or lower

[larley]

loaded extension on chromium browser i get this error 'background.scripts' requires manifest version of 2 or lower

just ignore it

[whs912km]

yea, right. but why this error from this new extension?
or this error is with chromium browser only and no error with FF browser?

also tried to edit manifest version 3 to version 2 but my browser can't load extension, with manifest version 2
just out curiosity...!

Among Chromium browsers, I think it is only going to work on Microsoft Edge. In Ungoogled Chromium there is no PlayReady CDM displayed in chrome://media-internals/
I tried implementing some PlayReady-to-ClearKey hook with LLM assistance, but it doesn't work yet and I have no idea how to pass information to jsplayready from content script. Maybe larley can help.

(function () {
  const originalRequest = navigator.requestMediaKeySystemAccess;

  navigator.requestMediaKeySystemAccess = async function (keySystem, supportedConfigurations) {
        if (["com.microsoft.playready.recommendation", "com.microsoft.playready.recommendation.3000", "com.microsoft.playready.hardware", "com.microsoft.playready", "com.youtube.playready"].includes(keySystem)) {
      const realKeySystem = "org.w3.clearkey";

      // Sanitize configurations for compatibility with ClearKey
      const modifiedConfigs = supportedConfigurations.map(config => {
        const sanitized = { ...config };

        sanitized.videoCapabilities = (config.videoCapabilities || []).map(cap => {
          const { robustness, ...rest } = cap;
          return rest;
        });

        sanitized.audioCapabilities = (config.audioCapabilities || []).map(cap => {
          const { robustness, ...rest } = cap;
          return rest;
        });

        // Optional: sanitize other fields like distinctiveIdentifier, persistentState, etc.
        return sanitized;
      });

      const access = await originalRequest.call(navigator, realKeySystem, modifiedConfigs);
      const originalCreate = access.createMediaKeys.bind(access);

      const wrappedAccess = {
        keySystem,
        getConfiguration: () => access.getConfiguration(),
        createMediaKeys: async () => {
          const realMediaKeys = await originalCreate();
          return createWrappedMediaKeys(realMediaKeys);
        }
      };

      return wrappedAccess;
    }

    return originalRequest.call(navigator, keySystem, supportedConfigurations);
  };

function createWrappedMediaKeys(realMediaKeys) {
  const originalCreateSession = realMediaKeys.createSession.bind(realMediaKeys);
  realMediaKeys.createSession = function (...args) {
    const realSession = originalCreateSession(...args);

    return new Proxy(realSession, {
      get(target, prop) {
        if (prop === "generateRequest") {
          return async (initDataType, initData) => {
            console.log("[CustomKeySystem] generateRequest", { initDataType, initData });
	    console.log(Object.keys(initData));
            if (initDataType == "cenc") {
	      const data = new Uint8Array(initData);
              //let pssh = Pssh(initData);
	      console.log(uint8ArrayToString(data));
              //const a = uint8ArrayToString(initData);
              //console.log(Object.keys(initData));
              return target.generateRequest("keyids", initData);
	    }
            return target.generateRequest(initDataType, initData);
          };
        }
        if (prop === "update") {
          return async (response) => {
            console.log("[CustomKeySystem] update", response);
            // {"keys":[{"kty":"oct","alg":"A128KW","kid":"nrQFDeRLSAKTLifXUIPiZg","k":"FmY0xnWCPCNaSpRG-tUuTQ"}]}
            return target.update(response);
          };
        }
        return typeof target[prop] === "function"
          ? target[prop].bind(target)
          : target[prop];
      }
    });
  };

  return realMediaKeys;
}
})();

background and content script communicate through a message proxy that converts one type of event to another and adds a unique id to each one to track which have arrived and which haven't. It's a true pain but also the only way possible.

async function processMessage(detail) {
    return new Promise((resolve, reject) => {
        chrome.runtime.sendMessage({type: detail.type, body: detail.body}, (response) => {
            if (chrome.runtime.lastError) {
                return reject(chrome.runtime.lastError);
            }
            resolve(response);
        });
    })
}

document.addEventListener('response', async (event) => {
    const { detail } = event;
    const responseData = await processMessage(detail);
    const responseEvent = new CustomEvent('responseReceived', {
        detail: detail.requestId.concat(responseData)
    });
    document.dispatchEvent(responseEvent);
});

From PlayreadyProxy2

const playready_device = new Device(Utils.base64ToBytes(device_b64));
const cdm = Cdm.fromDevice(playready_device);
const licenseChallenge = cdm.getLicenseChallenge(wrmHeader, rawRevLists, version);
const returned_keys = cdm.parseLicense(decodedLicense);
const keys = returned_keys.map(key => ({ k: utils.bytesToHex(key.key), kid: utils.bytesToHex(key.key_id) }));

Hello, and thank you very much for your help!

I tried PlayreadyProxy2 on Edge and Chrome, but it doesn't seem to be working.
Is this a PlayreadyProxy update?

Do I need the same configuration as for PlayreadyProxy (server, etc.), or just the .prd file and do roughly the same thing as for WidevineProxy2?

Thanks in advance
Sincerely,
Yanis

[larley]

everything is the same as with widevineproxy2 except that there will never be remote cdm support. and no it doesn't have anything to do with playreadyproxy

Hi,
Okay, great, thanks for taking the time to answer me. The tool is truly incredible from what I've tested (with WidevineProxy2).

Now I'm getting an error with WidevineProxy2 or PlayReadyProxy2.
The video isn't loading (normal), but I no longer have the key. At the bottom of the screen, it says:
ENGINE_ERROR / ENGINE_DRM_ERROR

Is this because my .wvp or .prd file is banned?
Or is it unrelated?

Thanks in advance.

EDIT : I dumped my own .wvd and it works again with WidevineProxy2
But if I want to download content from Canal+, I get the audio, but the video is encrypted.
I tried with PlayReadyProxy2, but I don't have anything in "Keys," and the video plays normally (even though the extension is enabled).

[ytdlhelp]

I tried with PlayReadyProxy2, but I don't have anything in "Keys," and the video plays normally (even though the extension is enabled).

Use Microsoft Edge web browser. Go to edge://flags to enable "Override software rendering list" (to force enable PlayReady DRM if your hardware doesn't support it) and disable "Widevine DRM". I suggested reimplementing the program to not require PlayReady support, but it isn't done yet.

And thanks for the work, @larley

[ytdlhelp]

Someone else developed the program that I suggested. I made a thread for it.
