在国外视频网站都早已采用html5播放器的时候,绝大部分国内视频网站还在用flash,比如B站。Flash这货已经快被淘汰了,刚好DIYgod开发了一款H5弹幕播放器DPlayer,可以拿来对接B站。原理很简单,服务端获取B站弹幕数据,转换为适用于DPlayer的格式用于播放。
1.获取B站视频源
GitHub上找到一个B站第三方API,可以获取视频源等信息:
GET http://bilibili-service.daoapp.io/view/3580782 (其中3580782 为AV号),接口返回:
- {
- "allow_bp": 1,
- "allow_download": 1,
- "allow_feed": 0,
- "author": "哔哩哔哩番剧",
- "bangumi": {
- "allow_download": "1",
- "bangumi_id": "1033",
- "season_id": "3271",
- "title": "极速老师"
- },
- "coins": "5584",
- "created": 1452804600,
- "created_at": "2016-01-15 04:50",
- "credit": "0",
- "description": "#02 枫的时间 ",
- "face": "http://i0.hdslb.com/user/9281/928123/myface.png",
- "favorites": "4621",
- "instant_server": "chat.bilibili.com",
- "list": {
- "0": {
- "cid": 5710510,
- "has_alias": false,
- "page": 1,
- "part": "",
- "type": "vupload",
- "vid": "vupload_5710510"
- }
- },
- "mid": "928123",
- "pages": 1,
- "pic": "http://i0.hdslb.com/video/9a/9a886536a807d717fe9bfe9bd811ed5b.jpg",
- "play": "979055",
- "review": "4630",
- "spid": null,
- "src": "c",
- "tag": "TV动画,洲崎绫,田中美海,冈本信彦,伊藤静,BILIBILI正版,黄老师,福山润,极速老师 第二季",
- "tid": 33,
- "title": "【1月】极速老师 第二季 02【独家正版】",
- "typename": "连载动画",
- "video_review": "46974"
- }
复制代码 list即为该视频的分P,我们需要的是分P的CID,比如上面这个只分了1P,CID为5710510。
再GET第二个接口 http://bilibili-service.daoapp.io/video/3580782?quality=2
参数:
- <font face="微软雅黑">quailty [int] 清晰度(1~2,根据视频有不同)
- type [int] 0:flv,1:hdmp4,2:mp4</font>
复制代码 接口返回
- <font face="微软雅黑">{
- "accept": "mp4,hdmp4",
- "backup": [
- "http://cc.acgvideo.com/201601191329/77fcfd7934552b0e2cf974e84d7d92ba/b/81/3580782-1.mp4",
- "http://ws.acgvideo.com/2/e8/3580782-1hd.mp4?wsTime=1453224424&wsSecret2=bdd28d4da66692521875ce8be36a2807&oi=2021932405&appkey=4ebafd7c4951b366&or=987503882"
- ],
- "url": "http://ws.acgvideo.com/2/e8/3580782-1.mp4?wsTime=1453224424&wsSecret2=cc4ff05eabce23fb761d568caf3c85db&oi=2021932405&appkey=4ebafd7c4951b366&or=987503882"
- }</font>
复制代码 成功拿到视频源http://ws.acgvideo.com/2/e8/3580 ... 53224424&wsSecret2=
cc4ff05eabce23fb761d568caf3c85db&oi=2021932405&appkey=4ebafd7c4951b366&or=987503882
2.获取弹幕数据
B站弹幕数据接口:comment.bilibili.com/[CID].xml,我写了个简单的py脚本可以将其转换为DPlayer适用的格式。
接口为:https://mm.aoaoao.me/?id=[CID]
在DPlayer的Options中:
- <font face="微软雅黑">var option = {
- element: document.getElementById('player1'), // Optional, player element
- autoplay: false, // Optional, autoplay video, not supported by mobile browsers
- theme: '#FADFA3', // Optional, theme color, default: #b7daff
- loop: true, // Optional, loop play music, default: true
- video: { // Required, video info
- url: '此处填写刚刚获取到的视频源URL', // Required, video url
- pic: '封面图' // Optional, music picture
- },
- danmaku: { // Optional, showing danmaku
- id: '此处填写视频CID', // Required, danmaku id, MUST BE UNIQUE, CAN NOT USE THESE IN YOUR NEW PLAYER: `https://dplayer.daoapp.io/list`
- api: '此处填写转换服务端URL', // Required, danmaku api
- token: 'tokendemo', // Optional, danmaku token for api
- maximum: 1000 // Optional, maximum quantity of danmaku
- }
- }</font>
复制代码 配置好后DPlayer可正常播放显示弹幕:
弹幕数据转换Python脚本:
- <font face="微软雅黑">import requests
- import sys
- from flask import Flask,make_response
- from flask import request
- from xml.etree import ElementTree
- reload(sys)
- sys.setdefaultencoding('utf-8')
- app = Flask(__name__)
- node_info = list()
- def get_node(node):
- if node.attrib.has_key("p") > 0 :
- node_list = [node.text,node.attrib['p']]
- danmuinfo = node.attrib['p'].split(",")
- node_info.append(node_list)
- danmu_type = danmuinfo[1].replace("1","right")
- danmu_type = danmu_type.replace("4","bottom")
- danmu_type = danmu_type.replace("5","top")
- danmu_text = str(node.text).replace('"',"")
- danmu_text = danmu_text.replace("'","")
- danmu_text = danmu_text.replace("\","/")
- return '{"_id":"'+danmuinfo[7]+'","author":"'+danmuinfo[6]+'","time":"'+danmuinfo[0]+'","text":"'+danmu_text+'","color":"#'+str(hex(int(danmuinfo[3])))[2:]+'","type":"'+danmu_type+'","player": ["bilibili469620"]},'
- @app.route('/', methods=['POST', 'GET'])
- def get_data():
- r = requests.get('http://comment.bilibili.com/'+request.args.get('id',0)+'.xml')
- root = ElementTree.fromstring(r.text)
- lst_node = root.getiterator("d")
- i = 1
- data = ""
- for node in lst_node:
- data = data + get_node(node)
- i = i + 1
- finall_data='{"code": 1,"danmaku": ['+data[:-1]+']}'
- response = make_response(finall_data,200)
- response.headers['Access-Control-Allow-Origin'] = '*'
- return response
- if __name__ == '__main__':
- app.run(host='0.0.0.0',threaded=True)</font>
