Android HLS首先播放段然后播放音频

我在播放只有音频的Android上播放HLS时遇到困难。该流将播放第一个视频片段，然后转换为仅音频流。下面是一个示例链路https://clipter.com/c/aymels8/hls.m3u8 Android HLS首先播放段然后播放音频

这是由每个URL后加入＃EXT-X-DISCONTINUITY标签解决。音频继续播放和视频停止的原因是因为每个视频片段具有相同的开始时间1.4（遗憾的是，在我的应用程序中，我无法更改该值）。有关更多详细信息，请参见https://tools.ietf.org/html/draft-pantos-http-live-streaming-13
