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 = new Date().getTime()
var t2 = t1
var interval = 0
var logName = ''
t1 = process.uptime()*1000
var emots = {

参数说明:
node.exe huya.js [虎牙房间号] [要存储目录的绝对路径] [文件名]
编写调用 huya.js 的 批处理文件 huyaDanmu.cmd
@echo off
title %1 %3 %date% %time%
D:\node-v8.9.1-win-x86\node.exe D:\node-v8.9.1-win-x86\node_modules\huya-danmu\huya.js %1 %2 %3
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] [文件名]
不输入存储目录时 直接保存到当前目录
不输入文件名时 自动取名为 YYMMDD-HHMMSS_房间号.LRC
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;
