Exo播放器添加引发/发送分析事件的总时间

如何解决Exo播放器添加引发/发送分析事件的总时间

我想为需要以下数据的exo播放器添加分析事件

• 在视频上花费的总时间
• 总播放时间
• 总暂停时间
• 暂停了多少时间

如何完成

尝试了以下回调，但无法找到确切的解决方案

hideWeight() {
     this.displayedColumns = ['position','name','symbol'];
}

showWeight() {
     this.displayedColumns = ['position','weight','symbol'];
}

还是我需要使用 AnalyticsListener ？

对此的更新发现，exo播放器库版本2.12.0已包含 PlaybackStatsListener ，它提供了大多数必需的分析数据，但数据不准确

Player.EventListener

这两个字段未显示准确或可靠的值。

解决方法

这是一段经过测试的代码，说明如何将onIsPlayingChanged与private var playTime = 0L // in ms private var pauseTime = 0L // in ms private var totalTime = 0L // in ms private var pressedPaused = 0 private val analyticsListener: AnalyticsListener = object : AnalyticsListener { private var initTime = 0L override fun onIsPlayingChanged(eventTime: AnalyticsListener.EventTime,isPlaying: Boolean) { if(isPlaying) { if(initTime != 0L) pauseTime += System.currentTimeMillis() - initTime initTime = System.currentTimeMillis() } else { if(initTime != 0L) playTime += System.currentTimeMillis() - initTime initTime = System.currentTimeMillis() pressedPaused++ } totalTime = playTime+pauseTime Log.e("onIsPlaying","PLAYTIME: $playTime") Log.e("onIsPlaying","PRESSEDPAUSE: $pressedPaused") Log.e("onIsPlaying","PAUSETIME: $pauseTime") Log.e("onIsPlaying","TOTALTIME: $totalTime") super.onIsPlayingChanged(eventTime,isPlaying) } } 结合使用

  <form id="form1"></form>
  <form id="form2"></form>
  <input ***form="form1"*** name="val1"/>
  <input ***form="form1"*** name="val2" type="hidden" />

  <input ***form="form2"*** name="val2"/>
  <input ***form="form2"*** type="button" name="Submit Form 2 ONLY">

  <input ***form="form1"*** type="button" name="Submit Form 1 data including form 2" 
         onsubmit="return copyFromForm2Function()">

,

private var mPlayTime = 0L
private var mPlayTotalTime = 0L

override fun onPlayerStateChanged(playWhenReady: Boolean,playbackState: Int) {
    if (playbackState == 3) {
        if (playWhenReady) {
            mPlayTime = System.currentTimeMillis()
        } else {
            if (mPlayTime.toInt() != 0) {
                val mPauseTime = System.currentTimeMillis() - mPlayTime
                mPlayTotalTime += mPauseTime
                mPlayTime = 0
            }
        }
    } else {
        if (mPlayTime.toInt() != 0) {
            val mPauseTime = System.currentTimeMillis() - mPlayTime
            mPlayTotalTime += mPauseTime
            mPlayTime = 0
        }
    }
    val mTotalDurationInSec = (mPlayTotalTime / 1000) % 60
}
