Biligrab 0.3 linux与OSX下自动抓B站视频和弹幕的东西（更新：修复重要BUG！！）

B站有自己的视频CDN了，咱们加进来。

对于海外有时比sina的蓝汛慢，但稳定。

差点break错了尼玛死。。。怪不得professor不让用呢。

更新：还是break错了。。。。。。。。。。。这个东西尽可能别用啊。

MIT，爱干啥干啥。

顺手扔上Gist，方便改：https://gist.github.com/superwbd/9605757

代码藏起来，否则主页太慢。

哦，你把全文看完了？

ffmpeg有3种Concat方法。我们用了最笨的。

因为别的方法都不支持H.264的不转码Concat。如果你使用MPEG，可以玩玩，那个的实现简单的多。

B站CDN現在完全沒速度永遠卡在那邊

  看来我得澄清一下。。。
  不是说，在Biligrab里面写“Oversea=1”，就一点会得到海外源。这个功能只是说，会使用B站的CDN的API进行解析，相当于你点了播放器的“视频源加速”。如果有自建CDN，那不排除会返回B站CDN，如果没有，会返回原始的源。
  当然这个我会再看一下。。。B站的海外CDN也不少，是美国的那个FDC有问题还是荷兰的FDC有问题？还是国内的哪台CDN呢？

    菊巨的軟件我都還沒測試過
    我是本地在看視頻時候
    B站那邊會永遠解析到中國內CDN節點
    有30分之1的機率會走新浪節點
    然後永遠不可能走荷蘭跟chicago那兩台………

      从IP来看，是hinet的IP呢。。
      因为我自己的IP段已经不在东亚好多年了（目前常出现的IP在美西和加东），所以也没啥好办法查到那边的CDN策略。。。
      那么，可以感觉到，在大陆乃至整个东南亚，Bilibili的确在大量使用自己的CDN以减轻sina的负担，免得sina寄刀片到杭州去。
      北美部分的CDN使用很少，即使是版权有问题的东西（难道是故意把海外版权问题扔给sina？）。当然极其偶尔也是会出现海外节点的。
      多说一句，这样看来，B站的运营成本现在已经不是特别低了。按理说可以推算出来，但是我没这个胆量用API大量抓取，会误伤别的软件的。。。也没那个能力啊。
      对于台湾来说，国际出口实在太少，如果使用北美乃至欧洲源就太不明智了。至少在这个大是大非上 Bilibili的CDN没有出错。当然会不会（或者能不能）根据具体的peering情况继续优化就不得而知了。。。大陆的一切peering信息都是天机不可泄露，不爽啊。
      另：咱比较懒，如果不更新会很长时间不更，一想起来有可能一天发一堆。。。总之最好用新版，增加了点小功能，防止报错啥的wwwww
