在主内容中进行搜寻的 VOD 播放 vod-playback-with-seeking-in-the-main-content
场景 scenario
此方案包括在播放期间在主内容中进行搜寻。
此方案与不含广告的 VOD 播放方案相同，但是部分内容会被清除，并且会完成从主内容的一个点到另一个点的搜寻。
触发器
心跳方法
网络调用
注释
播放内容的第一帧。
trackPlay心跳内容播放
当章节内容在主内容之前播放时，心跳在章节开始时开始。
用户开始对内容进行搜寻操作
trackSeekStart在搜寻结束（例如，
trackSeekComplete）前，不发出任何心跳搜寻操作结束
trackSeekComplete搜寻完成后心跳即开始发出。提示：播放头值应该表示搜寻后正确的新播放头。
会话结束
trackSessionEndSessionEnd示例代码 sample-code
在此方案中，用户将在主内容播放时进行搜寻。
Android
要在 Android 中查看此方案，请设置以下代码：
// Set up mediaObject
MediaObject mediaInfo = MediaHeartbeat.createMediaObject(
Configuration.MEDIA_NAME,
Configuration.MEDIA_ID,
Configuration.MEDIA_LENGTH,
MediaHeartbeat.StreamType.VOD
);
HashMap<String, String> mediaMetadata = new HashMap<String, String>();
mediaMetadata.put(CUSTOM_KEY_1, CUSTOM_VAL_1);
mediaMetadata.put(CUSTOM_KEY_2, CUSTOM_VAL_2);
// 1. Call trackSessionStart() when the user clicks Play or if autoplay is used,
// i.e., there is an intent to start playback.
_mediaHeartbeat.trackSessionStart(mediaInfo, mediaMetadata);
......
......
// 2. Call trackPlay() when the playback actually starts, i.e., whn the first frame
// of the main content is rendered on the screen.
_mediaHeartbeat.trackPlay();
.......
.......
// 3. Track the MediaHeartbeat.Event.SeekStart event when the user begins to seek.
_mediaHeartbeat.trackEvent(MediaHeartbeat.Event.SeekStart, null, null);
.......
.......
// 4. Track the MediaHeartbeat.Event.SeekComplete event when the user completes seeking
_mediaHeartbeat.trackEvent(MediaHeartbeat.Event.SeekComplete, null, null);

// 5. Call trackComplete() when the playback reaches the end, i.e., when the media
// completes and finishes playing.
_mediaHeartbeat.trackComplete();

........
// 6. Call trackSessionEnd() when the playback session is over. This method must be
// called even if the user does not watch the media to completion.
