 "Version": "1.0",
 "CredentialsProvider": {
   "CognitoIdentity": {
     "Default": {
       "PoolId": "us-west-2:01234567-89ab-cdef-0123-456789abcdef",
       "Region": "us-west-2"
 "IdentityManager": {
   "Default": {}
 "CognitoUserPool": {
   "Default": {
     "AppClientSecret": "abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmno",
     "AppClientId": "0123456789abcdefghijklmnop",
     "PoolId": "us-west-2_qRsTuVwXy",
     "Region": "us-west-2"
  1. Click gradle Sync and Build
  2. Run the demo application in simulator or in Android device (connected through USB).

5. Peer to Peer Streaming

On your Android device, open AWSKinesisVideoWebRTCDemoApp and sign up with Create New Account or sign in with existing accounts.

Note: This account information is stored in your Cognito User Pool and is not your AWS Console user name/password.

Once login is successful, you will entering the following channel information to start peer to peer streaming.

  1. Enter a channel name: e.g. demo-channel
  2. Enter AWS region: e.g. us-west-2
  3. Select audio if you would like to send both audio or video data.
  4. Optionally, when using it in viewer mode, you can enter a unique Client Id . Client ID is required only if multiple viewers are connected to a channel. This helps channel's master identify respective viewers.

To verify peer to peer streaming, do any of the following setup. In these setup, ensure that the signaling channel name, region, viewer ID, and the AWS account ID are the same.

5.1 Peer to Peer Streaming between two Android device: Master and Viewer

  • Start one Android device in master mode for starting a new session. Remote peer will be joining as viewer to this master. There should be only one master for any given channel.
  • Use another Android device to connect to the same channel name (started up in the step above as master) in viewer mode; this will connect to an existing session (channel) where a master is connected.
  • Verify media showing up in both Android devices.

5.2 Peer to Peer Streaming between Embedded SDK as master and Android device as viewer

  • Run Kinesis Video Streams WebRTC embedded SDK in master mode on a camera device.
  • Start the Android device in viewer mode - you should be able to check the video (and audio if selected both in embedded SDK) showing up in the Android device from the camera.
  • Verify media showing up from the Embedded SDK to the Android.

5.3 Peer to Peer Streaming between Android device as master and Web browser as viewer

  • Start one Android device in master mode for starting a new session.
  • Start the web browser using the Javascript SDK and start it as viewer.
  • Verify media showing up from the Android device to the browser.
