视频url:https://www.9meiju.cc/mohuankehuan/shandianxiadibaji/1-1.html
通过网络查找发现有俩个m3u8文件
url分别为
https://new.qqaku.com/20211117/iHVkqQMI/index.m3u8
https://new.qqaku.com/20211117/iHVkqQMI/2523kb/hls/index.m3u8
通过分析 第一个index.m3u8请求返回的内容中包含了第二个m3u8请求的url地址
也就是说通过第一个index.m3u8url请求返回包含第二个index.m3u8文件地址,通过拼接请求第二个index.m3u8后 返回了包含当前所有ts文件的地址内容
现在分析出了第二个真正的index.m3u8的地址,但是第一个地址从哪里来的呢,别慌,接下来我们来查找一下第一个url是从哪里来的
查找第一个index.m3u8的url地址
打开source
发现url存在页面源代码中的js里 知道了位置,在代码中通过正则匹配就可以获取到了
现在我们缕一下思路,通过页面源代码可以找到第一个index.m3u8的url,通过请求返回包含第二个index.m3u8文件的url内容,进行拼接,请求第二个m3u8的url,以此返回所有的ts内容

在获取index.m3u8文件的内容时,有的文件内容会显示…jpg/png的情况,并没显示…ts,那么遇到这种情况需要单独处理 内容如下:
这种情况使用上面的代码就无法进行正常合并,合并后的视频无法播放
但使用ffprobe分析,发现识别为png,进而导致无法正常拼接
在这种情况下,只需要将其中PNG文件头部分全部使用FF填充,即可处理该问题
填充后的效果如图

则需要下面处理后 才能进行合并

上面我们讲的是没有经过加密的 ts 文件,这些文件下载后直接可以播放,但经过AES-128加密后的文件下载后会无法播放,所以还需要进行解密。
如何判断是否需要加密?观察视频网站是否有m3u8的文件传输,下载下来并打开:

如果你的文件是加密的,那么你还需要一个key文件,Key文件下载的方法和m3u8文件类似,如下所示 key.key 就是我们需要下载的 key 文件,并注意这里 m3u8 有2个,需要使用的是像上面一样存在 ts 文件超链接的 m3u8 文件
下载所有 ts 文件,将下载好的所有的 ts 文件、m3u8、key.key 放到一个文件夹中,将 m3u8 文件改名为 index.m3u8,将 key.key 改名为 key.m3u8 。更改 index.m3u8 里的 URL,变为你本地路径的 key 文件,将所有 ts 也改为你本地的路径
文件路径
project/
ts/
0.ts
1.ts
…
index.m3u8
key.m3u8
修改后的index.m3u8内容如下所示:
#EXTM3U
