EncryptM3U8Server的加解密只是对ts文件名的加解密吗

不知道是不是那个地址的问题。。

比如一个视频长1小时，那我只需要下载某部分的 几分钟。

10个视频基本全部都失败，再重新尝试，会有几个成功的。

首先这个项目非棒，非常感谢! 下载超过4M 时会出错，不支持多个任务同时下载?

How to download a video with request headers? Is there a way to headers for download request?

反复暂停和重新能复现问题，查看下载目录能看到几个几B到几K大小的分片，建议参考fileDownloader的处理方式，未下载完成的文件进行重命名以便进行续传。

可以指定下载多少个ts吗？
可以指定从多少秒开始，到多少秒结束。进行下载吗？

Using Network Security Config from resource network_security_config debugBuild

看到readme里面有关于加密的处理方式
但是我走普通的下载流程，下载加密的m3u8可以下载，但是无法播放！
是下载加密的m3u8需要走其他流程吗 ？

parseIndex方法，以及Ts:

if (line.endsWith("m3u8")) {
    if(line.startsWith("/")) { // 取根路径
         return parseIndex(contactUrl(domainPath,line));
     } else { // 继承上一路径
        return parseIndex(contactUrl(basePath,line));
     }
 }

目前代码只能下载 Media playlist 不能支持 Master playlist 下载，是否打算支持？

How to add a request header for a download request?
I tried adding addRequestProperty("name", "www.com") to HttpURLConnection conn to M3U8Downloader.java but that didn't work

conn.addRequestProperty("name", "www.com");

Any help is really appreciated

下载这个直接报403，请问啥原因

什么时候能转一下Androidx吗

修改MUtils文件parseIndex()方法

String urlName = url;

// 打开和URL之间的连接

    Map<String, List<String>> map = conn.getHeaderFields();

    // 遍历所有的响应头字段
    for (String key : map.keySet()) {
        System.out.println(key + "--->" + map.get(key).get(0));
        if ("Location".equals(key)) {
            //获取新地址
            newUrl = map.get(key).get(0);
            System.out.println("newUrl--->" +newUrl);
            break;
        }
    }
    // 重新实例化url对象
    realUrl = new URL(newUrl);
    // 重新打开和URL之间的连接
    conn = realUrl.openConnection();

    // 建立实际的连接
    conn.connect();

    InputStream in = conn.getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(in,encoding));
    String basepath = url;

    if (url.contains("?")) {
        basepath = url.substring(0, url.lastIndexOf("?"));
    }
    basepath = basepath.substring(0, basepath.lastIndexOf("/") + 1);

    M3U8 ret = new M3U8();
    ret.setBasePath(basepath);

    String line;
    float seconds = 0;
    while ((line = reader.readLine()) != null) {
        if (line.startsWith("#")) {
            if (line.startsWith("#EXTINF:")) {
                line = line.substring(8);
                if (line.endsWith(",")) {
                    line = line.substring(0, line.length() - 1);
                }
                seconds = Float.parseFloat(line);
            }
            continue;
        }

        }
        ret.addTs(new M3U8Ts(line, seconds));
        seconds = 0;

    reader.close();

    return ret;
