/**
 * This example shows how DRM content protection can be applied to a fragmented MP4 muxing.
 * Acquisition of DRM keys is done by using the SPEKE protocol, and is configured to offer
 * compatibility with both PlayReady and Widevine on the one hand, using the MPEG-CENC
 * standard, and with Fairplay on the other hand. Separate outputs are created for both types
 * of encryption, due to them having different encryption mode. Separate manifests are also created
 * (DASH for CENC and HLS for FairPlay)
 *
 * <p>The following configuration parameters are expected:
 *
 * <ul>
 *   <li>BITMOVIN_API_KEY - Your API key for the Bitmovin API
 *   <li>BITMOVIN_TENANT_ORG_ID - (optional) The ID of the Organisation in which you want to perform
 *       the encoding.
 *   <li>HTTP_INPUT_HOST - The Hostname or IP address of the HTTP server hosting your input files,
 *       e.g.: my-storage.biz
 *   <li>HTTP_INPUT_FILE_PATH - The path to your input file on the provided HTTP server Example:
 *       videos/1080p_Sintel.mp4
 *   <li>S3_OUTPUT_BUCKET_NAME - The name of your S3 output bucket. Example: my-bucket-name
 *   <li>S3_OUTPUT_ACCESS_KEY - The access key of your S3 output bucket
 *   <li>S3_OUTPUT_SECRET_KEY - The secret key of your S3 output bucket
 *   <li>S3_OUTPUT_BASE_PATH - The base path on your S3 output bucket where content will be written.
 *       Example: /outputs
 *   <li>DRM_CONTENT_ID - (optional) The content ID that identifies your content within the SPEKE provider
 *   <li>DRM_KEY_ID - (optional) An additional 16-byte hex key ID that could be needed for some use cases
 *   <li>DRM_FAIRPLAY_IV - The initialisation vector for the FairPlay encryption configuration
 *   <li>SPEKE_URL - The URL of the SPEKE server.
 *       Example: https://my-speke-server.com/v1.0/vod
 * </ul>
 *
 * In addition, you need the following parameters to access the SPEKE server:
 *
 * <ul>
 *   <li>For authentication with AWS IAM:
 *     <ul>
 *       <li>SPEKE_ARN  -  The role ARN allowing access to the SPEKE server</li>
 *       <li>SPEKE_GATEWAY_REGION  -  The region of the associated AWS Gateway</li>
 *     </ul>
 *   </li>
 *   <li>For basic authentication:
 *     <ul>
 *       <li>SPEKE_USERNAME  -  The username to access the SPEKE server</li>
 *       <li>SPEKE_PASSWORD  -  The password to access the SPEKE server</li>
 *     </ul>
 *   </li>
 * </ul>
 *
 * <p>Configuration parameters will be retrieved from these sources in the listed order:
 *
 * <ol>
 *   <li>command line arguments (eg BITMOVIN_API_KEY=xyz)
 *   <li>properties file located in the root folder of the JAVA examples at ./examples.properties
 *       (see examples.properties.template as reference)
 *   <li>environment variables
 *   <li>properties file located in the home folder at ~/.bitmovin/examples.properties (see
 *       examples.properties.template as reference)
 * </ol>
