Description

When I use youtube-dl to download videos that consists of multi-part videos on bilibili , it only downloads the first video repeatedly.
Just like "https://www.bilibili.com/video/av55175398/?p=2", the "?p=<page_id>" param are just ignored and this tool can only download the video corresponds to "?p=1".
I think we can add a playlist extractor.And make some changes to the function _real_extract in bilibili.py. But I am not sure if it works.

Hey guys, not sure if I understand correctly. please help. So this fix has already been merged and can be used in youtube-dl latest build right?
The reason I'm asking is: the other day I tried to download this Kpop concert with 2 parts:

1. https://www.bilibili.com/video/av57748844?p=1
2. https://www.bilibili.com/video/av57748844?p=2

However, youtube-dl returns the same video for both links:

Am I doing something wrong?
