使用exoplayer 2制作iptv频道应用程序。一切正常，视频可以在手机上播放，但是当我在android上运行应用程序时，播放器处于缓冲模式，无法播放，并且应用程序崩溃。
我检查了exoplayer的常见问题，他们说
当要求播放ExoPlayer缺少AUD或IDR关键帧的MPEG-TS文件时，ExoPlayer似乎停留在缓冲状态。如果需要播放此类文件，则可以分别使用FLAG_DETECT_ACCESS_UNITS和FLAG_ALLOW_NON_IDR_KEYFRAMES进行播放。可以使用setTsExtractorFlags在DefaultExtractorsFactory上设置这些标志。
您能帮我如何在Android框中完美添加标记或运行应用吗？
