【问题描述】：

我需要在 android studio 中解析 m3u8 内容。我尝试了几次使用 github 库，例如 open-m3u8。但我无法解析这个。请帮我解决这个问题。

谢谢。

我尝试了几次使用 github 库，例如 open-m3u8。但这说明格式不好。我不确定这个异常错误。

我应该通过这个解析得到 4 通道数据。

【解决方案1】：

ExoPlayer 包含一个 m3u8 HLS 播放列表解析器，源代码可用：

https://github.com/google/ExoPlayer/blob/44293e8f45fc62ff918001b4425c44d0ded5ffc9/library/hls/src/main/java/com/google/android/exoplayer2/source/hls/playlist/HlsPlaylistParser.java

顶层看起来像这样 - 您可以看到它遍历 m3u8 文件（有时称为清单）中的每一行，并确定该行中的信息类型以允许它正确解释每一行：

@Override
  public HlsPlaylist parse(Uri uri, InputStream inputStream) throws IOException {
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
    Queue<String> extraLines = new ArrayDeque<>();
    String line;
    try {
      if (!checkPlaylistHeader(reader)) {
        throw new UnrecognizedInputFormatException("Input does not start with the #EXTM3U header.",
            uri);
      }
      while ((line = reader.readLine()) != null) {
        line = line.trim();
        if (line.isEmpty()) {
          // Do nothing.
        } else if (line.startsWith(TAG_STREAM_INF)) {
          extraLines.add(line);
          return parseMasterPlaylist(new LineIterator(extraLines, reader), uri.toString());
        } else if (line.startsWith(TAG_TARGET_DURATION)
            || line.startsWith(TAG_MEDIA_SEQUENCE)
            || line.startsWith(TAG_MEDIA_DURATION)
            || line.startsWith(TAG_KEY)
            || line.startsWith(TAG_BYTERANGE)
            || line.equals(TAG_DISCONTINUITY)
            || line.equals(TAG_DISCONTINUITY_SEQUENCE)
            || line.equals(TAG_ENDLIST)) {
          extraLines.add(line);
          return parseMediaPlaylist(
              masterPlaylist, new LineIterator(extraLines, reader), uri.toString());
        } else {
          extraLines.add(line);
        }
      }
    } finally {
      Util.closeQuietly(reader);
    }
    throw new ParserException("Failed to parse the playlist, could not identify any tags.");
  }
