跳过一个章节的 VOD 播放

方案

在此方案中,用户将跳过主内容中的一章。

此方案与包含一个章节的 VOD 播放方案相同,但此例中的用户希望从章节中搜寻,从而跳过该章节以进入主内容。

触发器 心率方法 网络调用 注释
用户点击​播放 trackSessionStart Analytics 内容开始,心率内容开始 测量库不知道存在一个前置广告。这些网络调用仍然与 iOS 种不含广告的播放方案完全相同。
章节开始。 trackEvent:ChapterStart 心率章节开始
将播放章节的第一帧。 trackPlay 心率章节播放 当章节内容在主内容之前播放时,我们希望在章节开始时开始播放心率。
将播放章节。 章节心率
搜寻开始跳过第一章。 trackEvent:trackSeekStart 搜寻期间没有心率
搜寻结束。 trackEvent:trackSeekComplete 心率会继续发布此内容。
应用程序可实现用户从常规的章节边界进行搜寻。 trackEvent:trackChapterSkip
将播放内容。 内容心率
内容结束播放。 trackComplete 心率内容结束 此网络调用与 iOS 中没有中断的播放方案完全相同。
会话结束。 trackSessionEnd SessionEnd 是指观看会话结束。即使用户没有观看至媒体结束,也必须调用此 API。

参数

在章节播放过程中使用的参数与包含一个章节的 VOD 播放方案中的参数相同,不同之处在于没有章节结束网络调用。

示例代码

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);

......
......

// Chapter
HashMap<String, String> chapterMetadata = new HashMap<String, String>();
chapterMetadata.put(CUSTOM_KEY_1, CUSTOM_VAL_1);
MediaObject chapterDataInfo =
MediaHeartbeat.createChapterObject(CHAPTER_NAME,
                                   CHAPTER_POSITION,
                                   CHAPTER_LENGTH,
                                   CHAPTER_START_TIME);

// 2. Track the MediaHeartbeat.Event.ChapterStart event when the chapter starts to play.
_mediaHeartbeat.trackEvent(MediaHeartbeat.Event.ChapterStart,
                         chapterDataInfo,
                         chapterMetadata);

.......
.......

// 3. Call trackPlay() when the playback actually starts, i.e., when the first frame
//    of the main content is rendered on the screen.
_mediaHeartbeat.trackPlay();

.......
.......

// 4. Track the MediaHeartbeat.Event.SeekStart event when the user begins to seek out
//    of the chapter with the intent to skip it.
_mediaHeartbeat.trackEvent(MediaHeartbeat.Event.SeekStart, null, null);

.......
.......

// 5. Track the MediaHeartbeat.Event.SeekComplete event when the user seeks out of the
//    chapter with the intent to skip it.
_mediaHeartbeat.trackEvent(MediaHeartbeat.Event.SeekComplete, null, null);

.......
.......

// 6. Track the MediaHeartbeat.Event.ChapterSkip event because the user skipped the
//    chapter by seeking out of it in the steps above.
_mediaHeartbeat.trackEvent(MediaHeartbeat.Event.ChapterSkip, null, null);

.......
.......

// 7. Call trackComplete() when the playback reaches the end, i.e., when the media
//    completes and finishes playing.
_mediaHeartbeat.trackComplete();

........

........

// 8. Call trackSessionEnd() when the playback session is over. This method must be
//    called even if the user does not watch the media to completion.
_mediaHeartbeat.trackSessionEnd();
