廣告插播時間點

Android TV 接收器 SDK 原生支援廣告插播和隨播廣告特定媒體串流中的廣告

處理含有廣告插播的負載

在 Android TV 應用程式中，暫停時間會顯示於 MediaLoadRequestData。系統會正常處理載入要求，並 AdBreakClipInfo 秒和 AdBreakInfo 秒最新資訊 MediaInfo：

Kotlin

class MyMediaLoadCommandCallback : MediaLoadCommandCallback() {
  override fun onLoad( senderId: String?, loadRequestData: MediaLoadRequestData
   ): Task {
    return Tasks.call {
      // Resolve the entity into your data structure and load media.
      val mediaInfo = loadRequestData.mediaInfo
      ...
      myPrepareAdBreaks(mediaInfo.adBreakClips, mediaInfo.adBreaks)
      // Update media metadata and state (this clears all previous status
      // overrides).
      castReceiverContext.getMediaStatusModifier()
          .setDataFromLoad(mediaInfo) // Ad breaks are set on the modifier.
      castReceiverContext.getMediaManager().broadcastMediaStatus()
      // Return the resolved MediaLoadRequestData to indicate load success.
      return loadRequestData
    }
  }
}

Java

public class MyMediaLoadCommandCallback extends MediaLoadCommandCallback {
  @Override
  public Task onLoad(String senderId, MediaLoadRequestData loadRequestData) {
    return Tasks.call(() -> {
        // Resolve the entity into your data structure and load media.
        MediaInfo mediaInfo = loadRequestData.getMediaInfo();
        ...
        myPrepareAdBreaks(mediaInfo.getAdBreakClips(), mediaInfo.getAdBreaks());
        // Update media metadata and state (this clears all previous status
        // overrides).
        castReceiverContext.getMediaStatusModifier()
            .setDataFromLoad(mediaInfo); // Ad breaks are set on the modifier.
        castReceiverContext.getMediaManager().broadcastMediaStatus();
        // Return the resolved MediaLoadRequestData to indicate load success.
        return loadRequestData;
    });
    }
}

正在更新廣告插播時間點

當廣告開始播放時，請更新 AdBreakStatus敬上的 MediaStatusModifier 廣播您的應用程式已開始播放廣告：

Kotlin

val breakStatus = AdBreakStatus.Builder()
        .setBreakId("b1")
        .setBreakClipId("bc1")
        .setCurrentBreakClipTimeInMs(breakClipProgress)
        .setCurrentBreakTimeInMs(breakProgress)
        .setWhenSkippableInMs(5000) // Set this field so that the ad break clip is skippable
        .build()

castReceiverContext.getMediaStatusModifier()
        .setAdBreakStatus(breakStatus)

Java

AdBreakStatus breakStatus =
    new AdBreakStatus.Builder()
        .setBreakId("b1")
        .setBreakClipId("bc1")
        .setCurrentBreakClipTimeInMs(breakClipProgress)
        .setCurrentBreakTimeInMs(breakProgress)
        .setWhenSkippableInMs(5000)  // Set this field so that the ad break clip is skippable
        .build();

castReceiverContext.getMediaStatusModifier()
    .setAdBreakStatus(breakStatus);

您也可以在載入項目後，以動態方式修改廣告插播時間點：

Kotlin

var breakClip1: AdBreakClipInfo = ...
var breakClip2: AdBreakClipInfo = ...
var breakClip3: AdBreakClipInfo = ...

var break1: AdBreakInfo = ...
var break2: AdBreakInfo = ...

mediaManager.getMediaStatusModifier().getMediaInfoModifier()
    .setAdBreakClips({breakClip1, breakClip2, breakClip3})
    .setAdBreaks({break1, break2})

Java

AdBreakClipInfo breakClip1 = ...
AdBreakClipInfo breakClip2 = ...
AdBreakClipInfo breakClip3 = ...

AdBreakInfo break1 = ...
AdBreakInfo break2 = ...

mediaManager.getMediaStatusModifier().getMediaInfoModifier()
    .setAdBreakClips({breakClip1, breakClip2, breakClip3})
    .setAdBreaks({break1, break2});

啟用及處理廣告略過

廣告出現時間點時，傳送者會顯示用來略過目前內容的按鈕可略過的廣告時段為允許使用者略過廣告中斷片段，請使用 MediaStatusModifier敬上加入 COMMAND_SKIP_AD 媒體指令：

Kotlin

mMediaManager.getMediaStatusModifier().setMediaCommandSupported(MediaStatus.COMMAND_SKIP_AD, true)

Java

mMediaManager.getMediaStatusModifier().setMediaCommandSupported(MediaStatus.COMMAND_SKIP_AD, true);

如要處理 SKIP_AD 指令，請實作 onSkipAd 回呼 MediaCommandCallback：

Kotlin

class MyMediaCommandCallback : MediaCommandCallback() {
    override fun onSkipAd(requestData: RequestData?): Task {
        // Skip your ad
        ...
        return Tasks.forResult(null)
    }
}

val mediaManager = CastReceiverContext.getInstance().mediaManager
mediaManager.setMediaCommandCallback(MyMediaCommandCallback())

Java

public class MyMediaCommandCallback extends MediaCommandCallback {
  @Override
  public Task onSkipAd(RequestData requestData) {
    // Skip your ad
    ...
    return Tasks.forResult(null);
  }
}

MediaManager mediaManager =
    CastReceiverContext.getInstance().getMediaManager();
mediaManager.setMediaCommandCallback(new MyMediaCommandCallback());

用戶端拼接

用戶端拼接是廣告不在串流中嵌入的位置針對 Cast Connect、更新 AdBreakStatus敬上的 MediaStatusModifier 您必須將播放速度設為 0 PlaybackStateCompat 讓寄件者知道要凍結內容時間軸進度。

Kotlin

// Playback speed should be 0 if content is not playing.
if (adIsPlaying) {
    playbackSpeed = 0.0f
}
val stateBuilder = PlaybackStateCompat.Builder()
    .setActions(AVAILABLE_MEDIA_ACTIONS)
stateBuilder.setState(playbackStateCompat, position, playbackSpeed)
mediaSession.setPlaybackState(stateBuilder.build())

Java

// Playback speed should be 0 if content is not playing.
if (adIsPlaying) {
    playbackSpeed = 0.0f;
}
PlaybackStateCompat.Builder stateBuilder = new PlaybackStateCompat.Builder()
    .setActions(AVAILABLE_MEDIA_ACTIONS);
stateBuilder.setState(playbackStateCompat, position, playbackSpeed);
mediaSession.setPlaybackState(stateBuilder.build());

廣告播完後，建議您恢復先前的播放速度。

伺服器端拼接

適用對象伺服器端拼接因為伺服器應該提供單一串流包含內容和廣告在這種情況下，播放功能可以繼續播放時間軸會正常進行，因為時間軸包含廣告時間長度讀者
