AWS Elemental Integration

Overview

PallyCon KMS supports SPEKE (Secure Packager and Encoder Key Exchange), which issues the keys required for Multi DRM packaging in AWS Elemental MediaConvert and MediaPackage.

PallyCon KMS URL may be set to the URL of DRM encryption setting of AWS Elemental, then the link is completed easily. This guide explains how to integrate with MediaConvert or MediaPackage service.

Tutorial Video

This video is a tutorial for enabling DRM encryption on MediaConvert and playing the DASH VOD DRM content.

For optimal playback, select ‘1080p’ as the video quality and enable subtitle (Korean or English) before starting playback.

MediaConvert integration

Create MediaConvert IAM role

Please refer to IAM Settings AWS Guide Document and proceed as follows.

  1. In the AWS Console, select the IAM service.
  2. Click the Roles tab and select create role.
  3. Select MediaConvert and click the Next: permission button.

  4. Confirm the S3 Access and APIGateway access permissions and click Next: Review button. iam1

  5. Set RoleName to MediaConvert-role and click the create role button. iam2

Set MediaConvert IAM role

  1. In the AWS Console, select the MediaConvert service.
  2. Click the create job button on the Jobs tab to start job creation.
  3. Select the MediaConvert-role created in the previous step in the IAM role setting section of the Job settings screen. mediaconvert0

Set MediaConvert Input

  1. In the Input field, enter the content path to be packaged in s3. mediaconvert1

Set MediaConvert Output groups

  1. Add the ouptput to the output groups by pressing the Add button. (Dash ISO for PlayReady and Widevine, Apple HLS for FairPlay) mediaconvert2

  2. In Custom group name, enter a name that is easy for you to identify.

  3. In the Destination field, type the path on s3 that contains the package-completed file. mediaconvert3

  4. Select the DRM encryption option, and then enter the Resource ID, System ID, and URL.

    • Resource ID : It is a value corresponding to the content ID (CID) in the integration specification in Multi DRM License Integration Guide.
    • System ID : The DRM-specific system id value specified in Dash System ID. You need to set PlayReady and Widevine ID for DASH output(as shown below) and set FairPlay ID for HLS output.
      • PlayReady : 9A04F079-9840-4286-AB92-E65BE0885F95
      • Widevine : EDEF8BA9-79D6-4ACE-A3C8-27DCD51D21ED
      • FairPlay : 94CE86FB-07FF-4F43-ADB8-93D2FA968CA2

    • URL : Enter the following KMS URL. The enc-token at the end of the URL is an API authentication token that is generated when you sign up PallyCon service, and can be found on the PallyCon Console site.

      https://kms.pallycon.com/cpix/getKey?enc-token={enc-token}

  5. Set the Outputs and click the Create button.

    • In case of widevine, it is mandatory to create the video and audio track separately because there are clients that can not play if you do not divide video and audio tracks into output. (click ‘add output’ button to add track)

  6. Make public or set permission on the S3 storage to play the generated file stored on it.

MediaPackage integration

Content can be encrypted in real time in conjunction with services such as AWS MediaLive which can upload HLS.

Note: In order to perform DRM packaging in MediaPackage, you must turn off Encryption in the Output Group of MediaLive.

Create MediaPackage IAM role

  1. Create the same as MediaConvert IAM Authorization, and create only Role Name with SPEKEAccess.

  2. On the Roles tab, select SPEKEAccess role and click the Edit trust relationship button on the Trust relationships tab. iam3

  3. Change the value of Principal.Service to mediapackage.amazonaws.com and click the Update button. iam4

Create MediaPackage Channel

  1. In the AWS Console, select the MediaPackage service.

  2. Create a channel. mediapackage0

  3. At the endpoints, press the Add button to set the endpoint.

  4. Set the endpoint name, packager settings, etc. according to the desired content specification.

  5. Configure Encryption and Outputs in the same way as MediaConvert Output groups setting no. 4.

  6. Enter the SPEKEAccess Role created in Role ARN.

  7. Click the Save button. mediapackage1

Integrate PallyCon KMS on AWS API Gateway (Optional)

  • If PallyCon KMS server is set to AWS API Gateway and error occurs during PallyCon KMS server connection, you can check the error.

  • PallyCon provides API Gateway construction through AWS CloudFormation for easy integration and building of AWS API Gateway.

This step is optional and you can apply DRM packaging to AWS Media Services without the following API Gateway integration.

Confiture CloudFormation

  1. In the AWS Console, select the CloudFormation service.

  2. Click the Create new stack button. mediapackage1

  3. Choose a template, select Upload a template to Amazon S3, enter the template file provided by PallyCon and click the Next button. Download template mediapackage2

  4. Enter the values required to build the API Gateway and click the Next button. mediapackage3

  5. After setting the Option value, click the Next button. mediapackage4

  6. Click the Create button. mediapackage5

  7. When API Gateway is successfully created, the status value of CloudFormation’s stack is set to CREATE_COMPLETE. mediapackage6

API Gateway Test

  1. In the AWS Console, select the API Gateway service.

  2. Click the Test button that appears when you select ANY under {proxy +} in Resources of the api gateway created with CloudFormation. apigateway1

  3. Select “Get” method and click “Test” button after inputting /cpix/getKey/heartbeat in {proxy}. If SUCCESS returns in response body, it means the integration is working correctly. apigateway2

  4. When the gateway setting is completed, change the URL of Encryption setting part of MediaConvert and MediaPackage to URL using API Gateway. The API Gateay URL can be found on the stages tab. ex) https://kms.pallycon.com/cpix/getKey?enc-token=xxxx => https://v12n46uhyh.execute-api.ap-northeast-2.amazonaws.com/Production/cpix/getKey?enc-token=xxxx apigateway3 apigateway4

Support for key rotation

  • Key rotation via MediaPackage is currently not supported. It will be updated in the future.
