Step 6: 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="imaads" type="assocarray" alwaysNotify="true"/>
    <field id="isAdImpressionSent" 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" />
    <field id="enableCustomErrorReporting" 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"
}
m.MM.setField("config", MMConfig)

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.

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 2 seconds in the SDK.

m.MM.setField("seekThreshold", 5)

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 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.

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

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"
}

Step 5: Google IMA Ads Integration

This guide demonstrates how to integrate the Mediamelon Roku SDK into a sample video player app with Google Ima Ads, downloaded the basic example from GitHub.

5.1. Include MediaMelon Ad Plugin:

Include MMImaAdsPlugin.brs file into SDK.xml as shown below.

<?xml version = "1.0" encoding = "utf-8" ?>
<component name = "imasdk" extends = "Task">

<script type = "text/brightscript">
    <![CDATA[
        <!-- Your code goes here -->
    ]]>
</script>

<!-- MediaMelon IMA AdPlugin -->
<script type = "text/brightscript" uri="pkg:/Components/MMSmartStream/MMImaAdsPlugin.brs"/>
</component>

5.2. Create an IMA Stream Player:

Call MediaMelon APIs to notify adBreakStarted and adBreakEnded as shown below.

...
sub setupVideoPlayer()
  sdk = m.sdk
  m.player = sdk.createPlayer()
  ...
  m.player.adBreakStarted = Function(adBreakInfo as Object)
    ...
    'MediaMelon API to notify AdBreakStart'
    mmAdBreakStarted(adBreakInfo)
  End Function
  m.player.adBreakEnded = Function(adBreakInfo as Object)
    ...
    'MediaMelon API to notify AdBreakEnd'
    mmAdBreakEnded(adBreakInfo)
  End Function
End Sub

5.3. Add Event Listeners and Start the Stream:

After requesting your stream, add event listeners to track ad progress from MediaMelon SDK by calling an API addMediaMelonAdCallbacks .

Sub loadStream()
  sdk = m.sdk
  sdk.initSdk()
  setupVideoPlayer()
  request = sdk.CreateStreamRequest()
  ...
  m.streamManager = Invalid
  While m.streamManager = Invalid
    sleep(50)
    m.streamManager = sdk.getStreamManager()
  End While
  ...
  'MediaMelon Callback Register'
  addMediaMelonAdCallbacks(m.sdk, m.streamManager)
  m.streamManager.start()
End Sub
