I think it doesn't work now since bilibili has change the implementation of playlist. Here's how different parts are referenced now,
e.g.
https://www.bilibili.com/video/av28148919/?p=2
https://www.bilibili.com/video/av28148919/?p=3

Current implementation only takes care of downloading parts of the same video, not the videos from the playlist. The parameter "?p=4" is currently ignored. Regardless of the "p" number, it's always use the cid of the 1st video of the playlist. Need to parse the html to get different cid for different "p" (i.e. "page").
