1 首先安装nodejs运行环境, 从 http://nodejs.cn/download/ 下载对应的版本
2 安装 huya-danmu 模块, https://github.com/BacooTang/huya-danmu 有详细的安装方法
3 参照 huya-danmu 模块中 test.js 编写 huya.js 新文件
const huya_danmu = require(‘./index‘)var fs = require(‘fs‘)const roomid = process.argv[2]const client = new huya_danmu(roomid)var t1 = 0var t2 = 0var interval = 0var logName = ‘‘var emots = {"/{dx" : "[大笑]","/{sh" : "[送花]","/{tx" : "[偷笑]","/{dk" : "[大哭]","/{hh" : "[嘿哈]","/{66" : "[666]","/{gd" : "[感动]","/{yw" : "[疑问]","/{xh" : "[喜欢]","/{jx" : "[奸笑]","/{zan" : "[赞]","/{ka" : "[可爱]","/{am" : "[傲慢]","/{kx" : "[开心]","/{88" : "[拜拜]","/{hx" ?: "[害羞]","/{zs" ?: "[衰]","/{pu" ?: "[吐血]","/{zc" ?: "[嘴馋]","/{sq" ?: "[生气]","/{fe" ?: "[扶额]","/{bz" ?: "[闭嘴]","/{kw" ?: "[枯萎]","/{xu" ?: "[嘘]","/{xk" ?: "[笑哭]","/{lh" ?: "[流汗]","/{bk" ?: "[不看]","/{hq" ?: "[哈欠]","/{tp" ?: "[调皮]","/{gl" ?: "[鬼脸]","/{cl" ?: "[戳脸]","/{dg" ?: "[大哥]","/{kun" : "[困]","/{yb" ?: "[拥抱]","/{zt" ?: "[猪头]","/{kl" ?: "[骷髅]","/{cc" ?: "[臭臭]","/{xd" ?: "[心动]","/{dao" : "[刀]"}function checkemot(str){ ???if(str.includes(‘/{‘) == false ) return str ???for(var key in emots) { ???????//console.log(key + ": " + emots[key]); ???????//str.replace(/key/g, emots[key]) ???????str = str.replace(new RegExp(key,‘g‘), emots[key]) ???} ???return str}function PFI(num){ ???if(num<10) ???????return ‘0‘+num ???else ????????return num}function getNowFormatDate() { ???var date = new Date(); ???var seperator1 = ""; ???var seperator2 = ""; ???var month = date.getMonth() + 1; ???var strDate = date.getDate(); ???if (month >= 1 && month <= 9) { ???????month = "0" + month; ???} ???if (strDate >= 0 && strDate <= 9) { ???????strDate = "0" + strDate; ???} ???????var strHH = date.getHours() ???var strMM = date.getMinutes() ???var strSS = date.getSeconds() ???if (strHH >= 0 && strHH <= 9) strHH = "0" + strHH; ???if (strMM >= 0 && strMM <= 9) strMM = "0" + strMM; ???if (strSS >= 0 && strSS <= 9) strSS = "0" + strSS; ???????????var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate ???????????+ "-" + strHH + seperator2 + strMM + seperator2 + strSS; ???return currentdate;}client.on(‘connect‘, () => { ???console.log(`已连接huya ${roomid}`) ???t1 = new Date().getTime() ???var savepath = process.argv[3] ???if(typeof(savepath)==‘undefined‘) ???????logName = ‘./‘+getNowFormatDate()+‘_‘+roomid+‘.LRC‘ ???else ???????logName = savepath+‘/‘+getNowFormatDate()+‘_‘+roomid+‘.LRC‘ ???t2 = t1 ???t1 = process.uptime()*1000 ???console.log(logName)})client.on(‘message‘, msg => { ???switch (msg.type) { ???????case ‘chat‘: ???????????//console.log(`[${msg.from.name}]:${msg.content}`) ???????????t2 = process.uptime()*1000 ???????????interval = (t2 - t1) ???????????var date = new Date( interval ) ???????????var HH = date.getUTCHours() ???????????var MM = PFI(date.getUTCMinutes()+HH*60) ???????????var SS = PFI(date.getUTCSeconds()) ???????????var MS = PFI(parseInt(date.getUTCMilliseconds()/10)) ???????????var msg = `[${MM}:${SS}.${MS}]${msg.content}` ???????????msg = checkemot(msg) ???????????console.log(`${msg}`) ???????????fs.appendFile(logName, msg+‘\n‘, function (err) {}) ???????????break ???????// case ‘gift‘: ???????????// console.log(`[${msg.from.name}]->赠送${msg.count}个${msg.name}`) ???????????// break ???????// case ‘online‘: ???????????// console.log(`[当前人气]:${msg.count}`) ???????????// break ???}})client.on(‘error‘, e => { ???console.log(e)})client.on(‘close‘, () => { ???console.log(‘close‘)})client.start()参数说明:
node.exe huya.js [虎牙房间号] [要存储目录的绝对路径]
编写调用 huya.js 的 批处理文件 huyaDanmu.cmd
@echo offtitle %1D:\node-v8.9.1-win-x86\node.exe D:\node-v8.9.1-win-x86\node_modules\huya-danmu\huya.js %1 %2
打开控制台窗口 输入 huyaDanmu [虎牙房间号] [要存储目录的绝对路径]
不输入存储目录时 直接保存到当前目录
保存的格式是 LRC 歌词文件, 如果想转换 SRT 或者 ASS 格式也很方便, 利用新版 FFMpeg 就可以
ffmpeg -i xxx.LRC xxx.SRT
ffmpeg -i xxx.LRC xxx.ASS
温馨提示: 录视频的同时运行 huyaDanmu 批处理命令, 就不用在调整时间轴;
虎牙直播弹幕转换字幕格式 基于Node.js 的 huya-danmu
