Question

我正在尝试使用Discord机器人播放音乐，并且我想使用ffmpeg来指定音乐的开始，这很好用，但是我只能使用ffmpeg下载音乐然后再播放。我希望ffmpeg对其进行处理，然后还对其进行流处理以播放音乐。

这是我用来下载然后播放音乐的代码：

message.member.voiceChannel.join().then((con, err) => {
    ytPlay.search_video(op, (id) => {
        let stream = ytdl("https://www.youtube.com/watch?v=" + id, {
            filter: "audioonly"
        });
        let audio = fs.createWriteStream('opStream.divx');

        proc = new ffmpeg({
            source: stream
        })
        proc.withAudioCodec('libmp3lame')
            .toFormat('mp3')
            .seekInput(35)
            .output(audio)
            .run();
        proc.on('end', function() {
            let input = fs.createReadStream('opStream.divx');
            console.log('finished');
            guild.queue.push(id);
            guild.isPlaying = true;
            guild.dispatcher = con.playStream(input);
        });
    });
})

是否可以做我想做的事情？如果可以，怎么做？

您可以使用discord.js的************* Module tmp tmp.py:5:0: W0001: Function fn_stmt is deprecated since version (not specified); reason: (not specified).

这对我来说很好

是可能的，我在我的机器人中做到了。首先，您需要安装ytdl-core

然后创建一个play.js文件，其中将包含流功能。这段代码将：在不下载歌曲的情况下获取youtube url并流式传输它，将歌曲添加到队列中，并在歌曲播放完毕后让机器人离开

根据需要编辑代码。

exports.run = async (client, message, args, ops) => {
    if (!message.member.voiceChannel) return message.channel.send('You are not connected to a voice channel!');


    if (!args[0]) return message.channel.send('Insert a URL!');
    let validate = await ytdl.validateURL(args[0]);

    let info = await  ytdl.getInfo(args[0]);

   let data = ops.active.get(message.guild.id) || {};
    if (!data.connection) data.connection = await message.member.voiceChannel.join();
    if(!data.queue) data.queue = [];
    data.guildID = message.guild.id;

    data.queue.push({
        songTitle: info.title,
        requester: message.author.tag,
        url: args[0],
        announceChannel: message.channel.id

    });

    if (!data.dispatcher) play(client, ops, data);
    else {
        message.channel.send(`Added to queue: ${info.title} | requested by: ${message.author.tag}`)
    }
    ops.active.set(message.guild.id, data);


}
async function play(client, ops, data) {
    client.channels.get(data.queue[0].announceChannel).send(`Now Playing: ${data.queue[0].songTitle} | Requested by: ${data.queue[0].requester}`);
    client.user.setActivity(`${data.queue[0].songTitle}`, {type: "LISTENING"});

    data.dispatcher = await data.connection.playStream(ytdl(data.queue[0].url, {filter: 'audioonly'}));
    data.dispatcher.guildID = data.guildID;

    data.dispatcher.once('end', function() {
        end(client, ops, this);

    });

}
function end(client, ops, dispatcher){

    let fetched = ops.active.get(dispatcher.guildID);

    fetched.queue.shift();

    if (fetched.queue.length > 0) {
        ops.active.set(dispatcher.guildID, fetched);
        play(client, ops, fetched);
    } else {
        ops.active.delete(dispatcher.guildID);

        let vc = client.guilds.get(dispatcher.guildID).me.voiceChannel;

        if (vc) vc.leave();


    }
  }
  module.exports.help = {
    name:"play"
  }```

将ffmpeg输出直接流式传输到调度程序
