MediaInfo
:
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 } } }
public class MyMediaLoadCommandCallback extends MediaLoadCommandCallback { @Override public TaskonLoad(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:
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)
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:
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})
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

加入
COMMAND_SKIP_AD
。
媒體指令:
mMediaManager.getMediaStatusModifier().setMediaCommandSupported(MediaStatus.COMMAND_SKIP_AD, true)
mMediaManager.getMediaStatusModifier().setMediaCommandSupported(MediaStatus.COMMAND_SKIP_AD, true);
如要處理 SKIP_AD
指令,請實作
onSkipAd
回呼
MediaCommandCallback
:
class MyMediaCommandCallback : MediaCommandCallback() { override fun onSkipAd(requestData: RequestData?): Task{ // Skip your ad ... return Tasks.forResult (null) } } val mediaManager = CastReceiverContext.getInstance().mediaManager mediaManager.setMediaCommandCallback(MyMediaCommandCallback())
public class MyMediaCommandCallback extends MediaCommandCallback { @Override public TaskonSkipAd(RequestData requestData) { // Skip your ad ... return Tasks.forResult(null); } } MediaManager mediaManager = CastReceiverContext.getInstance().getMediaManager(); mediaManager.setMediaCommandCallback(new MyMediaCommandCallback());

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。
// 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())
// 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
