Discord.js ytdl 错误：输入流：状态代码：416

Question

我有一个使用 ytdl 的音乐 Discord 机器人，偶尔，歌曲会随机停止并输出此错误：

Error: input stream: Status code: 416

这是我的 playSong 函数的代码

static playSong(queue, message) {
    const classThis = this;
    queue[0].voiceChannel
    .join()
    .then(function(connection) {
        const dispatcher = connection.play(ytdl(queue[0].url, {quality: 'highestaudio'}))
        .on('start', function() {
            message.guild.musicData.songDispatcher = dispatcher;
            dispatcher.setVolume(message.guild.musicData.volume);
            const videoEmbed = new Discord.MessageEmbed()
                .setThumbnail(queue[0].thumbnail)
                .setColor(embedSettings.color)
                .addField('Now Playing', `${queue[0].title} (${queue[0].url})`)
                .addField('Duration', queue[0].duration)
                .setFooter(embedSettings.footer, embedSettings.footer_url);
            if (queue[1]) videoEmbed.addField('Next Song:', queue[1].title);
            message.say(videoEmbed);
            message.guild.musicData.nowPlaying = queue[0];
            return queue.shift();
        })
        .on('finish', function() {
            if (queue.length >= 1) {
                return classThis.playSong(queue, message);
            } else {
                message.guild.musicData.isPlaying = false;
                message.guild.musicData.nowPlaying = null;
                message.guild.musicData.songDispatcher = null;
                if (message.guild.me.voice.channel) {
                    return message.guild.me.voice.channel.leave();
                }
            }
        })
}

当我将机器人移至 Discord Bot 托管服务时，错误发生的频率降低了，但仍然发生。这是我的代码问题，还是与 YouTube API 的连接问题？

我使用以下方法解决了这个问题：

const dispatcher = connection.play(ytdl(queue[0].url, {
    quality: 'highestaudio',
    highWaterMark: 1 << 25
}))

所以，对你来说：

static playSong(queue, message) {
    const classThis = this;
    queue[0].voiceChannel
    .join()
    .then(function(connection) {
        const dispatcher = connection.play(ytdl(queue[0].url, {quality: 'highestaudio', highWaterMark: 1 << 25 }))
        .on('start', function() {
            message.guild.musicData.songDispatcher = dispatcher;
            dispatcher.setVolume(message.guild.musicData.volume);
            const videoEmbed = new Discord.MessageEmbed()
                .setThumbnail(queue[0].thumbnail)
                .setColor(embedSettings.color)
                .addField('Now Playing', `${queue[0].title} (${queue[0].url})`)
                .addField('Duration', queue[0].duration)
                .setFooter(embedSettings.footer, embedSettings.footer_url);
            if (queue[1]) videoEmbed.addField('Next Song:', queue[1].title);
            message.say(videoEmbed);
            message.guild.musicData.nowPlaying = queue[0];
            return queue.shift();
        })
        .on('finish', function() {
            if (queue.length >= 1) {
                return classThis.playSong(queue, message);
            } else {
                message.guild.musicData.isPlaying = false;
                message.guild.musicData.nowPlaying = null;
                message.guild.musicData.songDispatcher = null;
                if (message.guild.me.voice.channel) {
                    return message.guild.me.voice.channel.leave();
                }
            }
        })
}
