Detecting ad slate in Dash Manifest from Exoplayer in Android

Question

I am developing a solution to detect ad slate in live content over SSAI.

So far we have been able to detect the ad slate in HLSManifest.

However I don't see any relevant object or information when it comes for DashManifest.

I see EventStream which is responsible for ad display

I am using the onTimelineChanged to read the manifest changes

override fun onTimelineChanged(timeline: Timeline, reason: Int) { 
    super.onTimelineChanged(timeline, reason)
 val manifest: Any? = exoPlayer.currentManifest 
   if (manifest is HlsManifest) readHLSManifest(manifest) 
   else if (manifest is DashManifest) readDASHManifest(manifest) 
}

Not able to figure what I can use for ad slate detection from Dash. Is it possible?

Too late on for the question, however for anyone stumbling onto it: You have rightly said that it would need EventStream. An example would be:

<EventStream
 schemeIdUri="urn:scte:scte35:2013:bin"
 timescale="1">
 <Event
 presentationTime="1525119000"
 duration="60"
 id="55"
 messageData="/DAhAAAAAAAAAP/wEAUAAAA3f+9/fgBSZcAAAAAAAAAmObEZ"/>
</EventStream>

Where messageData is base64 encoded msg.
