我在使用ExoPlayer时遇到了麻烦.我用一个来流式传输广播电台

Question

当流式传输广播电台时，流在一段时间延迟后停止并再次播放。并且此问题在蓝牙耳机中重现。

我像这样创造外线玩家

exoPlayer = SimpleExoPlayer.Builder(
this,
DefaultRenderersFactory(this),
DefaultTrackSelector(this),
DefaultLoadControl(),
bandwidthMeter,
Looper.getMainLooper(),
AnalyticsCollector(Clock.DEFAULT),
true,
Clock.DEFAULT
).build()

然后

exoPlayer.playWhenReady = true
prepareExoPlayer()
setSessionState(PlaybackStateCompat.STATE_PLAYING)
...
private fun prepareExoPlayer() {
val mediaSource = buildMediaSource()
exoPlayer.prepare(mediaSource)
}
private fun buildMediaSource(): MediaSource {
val dataSourceFactory = DefaultDataSourceFactory(
this,
Util.getUserAgent(baseContext, getString(R.string.app_name)),
bandwidthMeter
)
var url = currentStation.middleStream
return ProgressiveMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(url))
}

如果您使用ExoPlayer播放通过HTTP提供的音频，请尝试创建特定版本的工厂，例如：

val dataSourceFactory = DefaultHttpDataSourceFactory(
Util.getUserAgent(baseContext, getString(R.string.app_name))
)
