如何使用 discord.js 音乐机器人在歌曲中寻找一个点？

Question

我正在尝试用 ytdl-core 制作一个 discord.js 音乐机器人。我不太确定如何在使用命令时查找歌曲中的当前时间，并且搜索帮助并没有真正起到多大作用。该命令的工作方式类似于 !seek 1:30.

我想要了解的是：
a) 调度程序是否包含搜索功能？

//i.e like below
let ms = 90000; //would be converted from arguments
queue.connection.dispatcher.seek(ms) //Does this exist???

或 b) 如何在特定时间开始播放歌曲？

//Add the song again, but with a timestamp, and end current song
let seekedSong = queue.songs[0];
seekedSong.startTime = 90000; 
queue.songs.unshift(seekedSong);
queue.connection.dispatcher.end()
/* However, how do I start a song given a start time?
 * 
 * In my play.js file, which plays the next song in the queue automatically, 
 * how can i tell it to start at a time? I tried dispatcher.end() and supplying 
 * a youtube link with ?t={sec}s, but that didnt work
 */

Answer 1

Discord.js v12

VoiceConnection#play takes a second StreamOptions 参数。您可以使用 seek 属性:

指定要搜索的秒数

// When playing the song:
const stream = ytdl('https://youtu.be/dQw4w9WgXcQ')
// Store the stream somewhere
queue.currentSong = stream

// When seeking:
queue.connection.play(queue.currentSong, {seek: ms / 1000})

Answer 2

Discord.js V13

你可以这样使用 fluent-ffmpeg :

const fluentFfmpeg = require('fluent-ffmpeg')
let ms = 90000;

let song = ytdl('some youtube link', {quality: 'highestaudio'})

let editedSong = fluentFfmpeg({source: song}).toFormat('mp3').setStartTime(Math.ceil(ms/1000)) // set the song start time

queue.play(editedSong)
