Android HLS首先播放段然後播放音頻

我在播放只有音頻的Android上播放HLS時遇到困難。該流將播放第一個視頻片段，然後轉換爲僅音頻流。下面是一個示例鏈路https://clipter.com/c/aymels8/hls.m3u8 Android HLS首先播放段然後播放音頻

這是由每個URL後加入＃EXT-X-DISCONTINUITY標籤解決。音頻繼續播放和視頻停止的原因是因爲每個視頻片段具有相同的開始時間1.4（遺憾的是，在我的應用程序中，我無法更改該值）。有關更多詳細信息，請參見https://tools.ietf.org/html/draft-pantos-http-live-streaming-13
