exoplayer出错时如何跳过播放列表中的MP4视频
exoplayer出错时如何跳过播放列表中的MP4视频
提问于 2019-07-01 15:41:30
我正在使用ExoPlayer在安卓系统中播放视频。我有3个本地mp4文件，并想从这些文件创建播放列表。我正在使用ConcatenatingMediaSource将所有文件添加到一个播放列表中。
override fun playFromList(list: List<VideoEntity>) {
val userAgent = Util.getUserAgent(this, getString(R.string.app_name))
//2
val concatenatedSource = ConcatenatingMediaSource()
list.forEach {
if (it.localPath != null) {
val dataSourceFactory = DefaultDataSourceFactory(this, userAgent)
val extractorFactory = DefaultExtractorsFactory()
val mediaSource = ProgressiveMediaSource
.Factory(dataSourceFactory, extractorFactory)
.createMediaSource(Uri.parse(it.localPath))
concatenatedSource.addMediaSource(mediaSource)
}
exoPlayer.prepare(concatenatedSource)
}
exoPlayer.playWhenReady = true
exoPlayerView.player = exoPlayer
}不幸的是，有些文件在播放时会产生错误，导致exoplayer崩溃(不能播放其他视频)。
E/ExoPlayerImplInternal: Source error.
com.google.android.exoplayer2.source.UnrecognizedInputFormatException: None of the available extractors (MatroskaExtractor, FragmentedMp4Extractor, Mp4Extractor, Mp3Extractor, AdtsExtractor, Ac3Extractor, TsExtractor, FlvExtractor, OggExtractor, PsExtractor, WavExtractor, AmrExtractor, Ac4Extractor) could read the stream.
at com.google.android.exoplayer2.source.ProgressiveMediaPeriod$ExtractorHolder.selectExtractor(ProgressiveMediaPeriod.java:1059)
at com.google.android.exoplayer2.source.ProgressiveMediaPeriod$ExtractingLoadable.load(ProgressiveMediaPeriod.java:947)

at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641)
at java.lang.Thread.run(Thread.java:764)我的问题是，如何捕获该错误，以便我可以跳过该文件并继续播放其他文件？
谢谢

您需要将事件侦听器添加到exo播放器并在那里处理错误。
fun onPlayerError(error: ExoPlaybackException) {
when (error.type) {
ExoPlaybackException.TYPE_SOURCE -> Log.e(TAG, "TYPE_SOURCE: " + error.sourceException.message)
ExoPlaybackException.TYPE_RENDERER -> Log.e(TAG, "TYPE_RENDERER: " + error.rendererException.message)
ExoPlaybackException.TYPE_UNEXPECTED -> Log.e(TAG, "TYPE_UNEXPECTED: " + error.unexpectedException.message)
}
