java获取虎牙直播弹幕消息_虎牙直播弹幕转换字幕格式 基于Node.js 的 huya-danmu

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

1 const huya_danmu = require('./index')2 var fs = require('fs')3

4 const roomid = process.argv[2]5 const client = newhuya_danmu(roomid)6 var t1 = newDate().getTime()7 var t2 =t18 var interval = 0

9 var logName = ''

10 t1 = process.uptime()*1000

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

1 @echo off

2 title %1 %3 %date% %time%3 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

1 ffmpeg -i xxx.LRC xxx.SRT

2 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;
