NVA协议投屏失败

[jleaves]

遇到了类似 #19 的问题。安卓的Bilibili投屏到Windows的macast.exe，调用NVA协议失败。

Macast是0.7版本，NVA插件已更新到0.32版本。

这个应该是API失效了，我注意到BBDOWN也遇到了类似的问题：nilaoda/BBDown#901

这个问题如果要修复的话，有两个方案：

1. 找到新的投屏接口，我使用一个未登陆账号的安卓客户端确实可以向非官方DLNA接收器进行投屏，说明肯定有接口可以实现投放没有跨域限制的视频链接，需要有人花时间找到这样的接口。
2. 更新Macast本体，使其可以接受dash链接（视频音频分离）

我其实感觉对于Macast来说第二个方案最好，因为这可以保证高清视频的投放，但是选择这个意味着 插件间会存在不兼容，比如nva插件搭配不支持dash的potplayer插件就无法投屏了，所以最好是可以两个方案都选择。

但是这个显然是比较花时间的，我暂时没有时间来完善这个应用了。

顺便一提，欢迎为这个项目捐助，我会尽量找出来时间更新的：

简单完成了前面的方案1，顺便修复了一下直播无法投屏的问题，更新插件到 0.33 应该就可以了。

NVA插件更新后，Bilibili又可以在NVA模式下顺利投屏了。感谢火速更新！

那我就先关闭这个issue了
