我是Exoplayer udp流媒体的新手。我已经完成了一些关于HTTP直播但不是udp的工作。现在尝试在exoplayer上播放一个udp流,google了很多,但没有运气。
请查看以下logcat。
任何帮助都将不胜感激。

答案 0 :(得分:0)
您需要像
一样为Exo创建完全媒体源。val myDataSourceFactory = DefaultDataSourceFactory(this, null, { -> UdpDataSource(this, 2000, 20000) })
// Extractor factory & media source
val extractorsFactory = DefaultExtractorsFactory()
val mediaSource = ExtractorMediaSource(uri, myDataSourceFactory, extractorsFactory, null, null)
player?.prepare(mediaSource, true, false)
答案 1 :(得分:0)
即使使用以下代码,我也有同样的问题:
aExtractorMediaSourceFactory := TJExtractorMediaSource_Factory.JavaClass.init(fDataSourceFactory);
aVideoSource := aExtractorMediaSourceFactory.createMediaSource(StrToJURI(aDataSource));
aExtractorMediaSourceFactory := nil;
似乎总是使用HTTP源类,而不是默认数据源。
