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);
});
