I’m trying to runnig video sdk sample wih pure JS without Node on PHP.

I’ve found following video sdk cdn from forum, but not sure it is right or not.

// For ZoomVideo

Following is my code and There is an error “Zoomvideo is not defined.”

```auto
// For ZoomVideo
<script src="https://source.zoom.us/2.1.1/zoom-meeting-embedded-2.1.1.min.js"></script>
// For generateSignature
<script src="https://cdnjs.cloudflare.com/ajax/libs/jsrsasign/8.0.20/jsrsasign-all-min.js"></script>

<script>

function generateSignature(sdkKey, sdkSecret, sessionName, role, sessionKey, userIdentity) {

  const iat = Math.round((new Date().getTime() - 30000) / 1000)
  const exp = iat + 60 * 60 * 2
  const oHeader = { alg: 'HS256', typ: 'JWT' }

  const oPayload = {
    app_key: sdkKey,
    tpc: sessionName,
    role_type: role,
    session_key: sessionKey,
    user_identity: userIdentity,
    iat: iat,
    exp: exp
  }

  const sHeader = JSON.stringify(oHeader)
  const sPayload = JSON.stringify(oPayload)
  const sdkJWT = KJUR.jws.JWS.sign('HS256', sHeader, sPayload, sdkSecret)
  return sdkJWT
}

const client = ZoomVideo.createClient();
client.init('en-US', 'CDN');

token = generateSignature('My sdkKey Here', 'My SdkSecret Here', 'Cool Cars', 1, 'session123', 'user123');
topic = 'Cool Cars'
userName = 'user123';
password = 'session123';

// join
client.join(topic, token, userName, password);

// stream
stream = client.getMediaStream();

</script>
```

Hey @imslee100

Thanks for your feedback.  
The link of the `ZoomVideo` is not correct. It’s linked to the MeetingSDK Web.

Thanks  
Vic
