[bilibili] Support multiple formats

[CoXier]

In latest version ,bilibili.py has a bug:

payload = 'appkey=%s&cid=%s&otype=json&quality=1&type=mp4' % (self._APP_KEY, cid)

In my opinion,the type is which we choose such as mp4,flv,etc. 'type=mp4' means format of the file we download is 'mp4'.

In addition,quality param is enough.

Could you give examples for how to change the payload and what's the difference in the resultant video?

[CoXier]

My strategy

payload = 'appkey=%s&cid=%s&otype=json&quality=%s&type=' % (self._APP_KEY, cid,quality)

Note:I don't set type any format.

How to know the range of quality?

As one video has at least quality 1,I first set quality 1 then I use above payload to get json data,like this:

{
  "from": "local",
  "result": "suee",
  "format": "mp4",
  "timelength": 2501412,
  "accept_format": "mp4,hdmp4,flv",
  "accept_quality": [
    3,
    2,
    1
  ],
  "seek_param": "start",
  "seek_type": "second",
  "durl": [
    {
      "order": 1,
      "length": 2501412,
      "size": 138266475,
      "url": "http://ws.acgvideo.com/a/be/6997314-1.mp4?wsTime=1487136532&platform=pc&wsSecret2=50cee32c1f82ee8a2a2836a40911b966&oi=1078436452&rate=650"
    }
  ]
}

According to accept_quality,I know the range of quality.

After I know the range of quality

Just loop.

what's the difference in the resultant video?

If you set type mp4,you just get one quality json data so you just can download one quality video ,in this condition,result video's format is mp4.

[remitamine]

extracting all qualities will bring the problem in #6193.

[yan12125]

IIRC bilibili does not deliver segmented videos anymore.

[remitamine]

last time i checked(baa3e18), 720p(quality=3) is delivered as segmented flv videos.

Thanks. Then #6193 should be resolved first.
