Step 5: Variables and Description

Step 1: Include MediaMelon SmartStreaming SDK

To integrate, unzip the MediaMelon Roku library and place the MMSmartStream folder in the components directory.

SDK: MediaMelon Roku IMA SDK

Step 2: Setup a new MediaMelon Task

Create a new XML file MMTask.xml inside your components folder. This is used to link MediaMelon’s brsfiles into your application.

The MMTask.xmlfile should contain the following:

<component name="MMTask" extends="Task">
  <interface>
    <field id="video" type="node" alwaysNotify="true" />
    <field id="config" type="assocarray" alwaysNotify="true" />
    <field id="customConfig" type="assocarray" alwaysNotify="true" />    
    <field id="contentMetadata" type="assocarray" alwaysNotify="true" />
    <field id="customTags" type="assocarray" alwaysNotify="true" />
    <field id="error" type="assocarray" alwaysNotify="true"/>
    <field id="adError" type="assocarray" alwaysNotify="true"/>
    <field id="view" type="String" alwaysNotify="true" />
    <field id="exit" type="Boolean" alwaysNotify="true" />
    <field id="mmAdData" type="assocarray" alwaysNotify="true" />
    <field id="mmRafEvent" type="assocarray" alwaysNotify="true"/>
    <field id="mmAdPlaying" type="Boolean" alwaysNotify="true" />    
    <field id="sdk_version" type="String" alwaysNotify="true" />
    <field id="seekThreshold" type="Integer" alwaysNotify="true"/>
    <field id="codecs" type="assocarray" alwaysNotify="true" />
    <field id="isVideoLive" type="Boolean" alwaysNotify="true" />
  </interface>
  <script type="text/brightscript" uri="pkg:/components/MMSmartStream/MMSmartStreamWrapper.brs" />
  <script type="text/brightscript" uri="pkg:/components/MMSmartStream/MMSmartStreamEngine.brs" />
  <script type="text/brightscript" uri="pkg:/components//MMSmartStream/MMSmartStreamRokuPlugin.brs" />
  <script type="text/brightscript" uri="pkg:/components/MMSmartStream/Utilities.brs" />
</component>

Step 3: MediaMelon Code Integrate

3.1. Add MMTask Child Component:

Add the MediaMelon MMTask as a child component to the main video scene custom-playback-channel-master/components/MainScene.xml

<component name="MainScene" extends="Scene" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="https://devtools.web.roku.com/schema/RokuSceneGraph.xsd">
<!-- importing main handler -->
<script type="text/brightscript" uri="pkg:/components/MainScene.brs" />
<children>
    <MMTask id="MM"/>
</children>

3.2. Create MM Task Node:

In the main application, after the video instance has been created, create a MediaMelon Task node, and pass the Video node to it.

CUSTOMER_ID is your MediaMelon assigned Customer ID. If you do not know your Customer ID contact MediaMelon at [e-mail].

m.MM = m.top.FindNode("MM")
m.MM.setField("video", m.video)

3.3. Set Configuration Details:

MMConfig = {
  customerID: "CUSTOMER_ID"
  subscriberId: "SUBSCRIBER_ID"
  subscriberType: "SUBSCRIBER_TYPE"
  subscriberTag: "SUBSCRIBER_TAG"
  playerName: "Roku"
  disableManifestFetch: false
  domainName: "DOMAIN_NAME"
  appName: "APP_NAME"
  appSdkVersion: "APP_VERSION"
  viewSessionId: "VIEW_SESSION_ID"
  hashSubscriberId: false 'Important
  enableCustomErrorReporting: true 'Important
}
m.MM.setField("config", MMConfig)

• disableManifestFetch: If your workflow restricts the manifest to be accessible from both the player and SDK simultaneously, then you can disable manifest fetch. This is an optional step.

• hashSubscriberId: Set to true to hash the subscriberId and to false to process subscriberId without hashing.

• enableCustomErrorReporting: If set to true SDK will consider only client-reported errors else if set to false SDK will consider errors from the video node.

3.4. Set Content Metadata:

contentMetadata = {
  "assetName": "ASSET_NAME",
  "assetId": "ASSET_ID",
  "videoId": "VIDEO_ID",
  "genre": "GENRE",
  "drmProtection": "DRM_PROTECTION",
  "episodeNumber": "EPISODE_NUMBER",
  "season": "SEASON",
  "seriesTitle": "SERIES_TITLE",
  "contentType": "CONTENT_TYPE",
}
m.MM.setField("contentMetadata", contentMetadata)

3.5. Set Custom Configuration Details:

customConfig = {
  cdn: "CDN"
  experimentName: "EXPERIMENT_NAME"
  subPropertyId: "SUB_PROPERTY_ID"
  streamFormat: "STREAM_FORMAT"
  mediaType: "MEDIA_TYPE"
  drmProtection: "DRM_PROTECTION"
}
m.MM.setField("customConfig", customConfig)

3.6. Set Codecs:

codecs = {
  video: "VIDEO_CODEC"
  audio: "AUDIO_CODEC"
}
m.MM.setField("codecs", codecs)

3.7. Set Custom Metadata:

customMetadata = {
  "CUSTOM_KEY_1": "VALUE_1",
  "CUSTOM_KEY_2": "VALUE_2"
}
m.MM.setField("customTags", customMetadata)

3.8. Set Seek Threshold:

By default seek threshold is set to 1.25 seconds in the SDK.

m.MM.setField("seekThreshold", 2)

3.9. Set is Video Live:

Set isVideoLive to true for live video stream and to false for VOD stream

m.MM.setField("isVideoLive", true)

3.10. Set View:

It's important to set the view field start for every new view starts and to end when a view ends.

• Start View:

m.MM.setField("exit", false)
m.MM.setField("view", "start")

• End View:

m.MM.setField("view", "end")
m.MM.setField("exit", true)

3.11. Run the SDK:

m.MM.control = "RUN"
m.player.setFocus(true)

Step 4: Error Handling

By default, SDK listens to the video node for errors. To report custom errors set enableCustomErrorReporting flag to true in MMConfig and report the errors in the following way;

Upon setting enableCustomErrorReporting flag to true, SDK will stop listening to the video node errors. Only custom errors will be reported.

4.1. Video Error Reporting:

m.MM.error = { 
    errorCode: "ERROR_CODE",
    errorMessage: "ERROR_MESSAGE",
    errorDetails: "ERROR_DETAILS"
}

4.2. Ad Error Reporting:

m.MM.adError = { 
    errorCode: "ERROR_CODE",
    errorMessage: "ERROR_MESSAGE",
    errorDetails: "ERROR_DETAILS"
}
