• Discord Music Bot No Playback Issue

  6 août 2021, par Kusunoki

  I'm trying to configure a discord music bot and my code is working (Other people have tried my code and it works perfectly on their side) but the problem is whenever the bot joins the voice channel, it doesn't play any music then it will queue the video but not play it then the bot will leave the channel.

  


  The code also works on repl.it and I've tried it several times and it seems to be working fine. I'm running Windows 10 LTSC on my PC.

  


  I've tried reinstalling the packages, trying the node.js v14 and 15, reinstalling ffmpeg and nothing seems to be working.

  


  Code :

  


  module.exports = {
    name: 'play',
    category: 'music',
    description: 'Play music from discord!',
    async execute(message, args, ytdl, ytSearch) {
        const voiceChannel = message.member.voice.channel;

        if (!voiceChannel) return message.channel.send("Connect to a music channel.");
        const userPermissions = voiceChannel.permissionsFor(message.client.user);
        if (!userPermissions.has('CONNECT')) return message.channel.send("You\'re not allowed to play music.");
        if (!userPermissions.has('SPEAK')) return message.channel.send("You\'re not allowed to play music.");

        const connection = await voiceChannel.join();
        const videoFinder = async (query) => {
            const videoResult = await ytSearch(query);
            return (videoResult.videos.length > 1) ? videoResult.videos[1] : null;
        }
        const video = await videoFinder(args.join(' '));
        if (video){
            const stream = ytdl(video.url, {filter: 'audioonly'});
            connection.play(stream, {seek: 0, volume: 1})
            .on('finish', () =>{
                voiceChannel.leave();
                console.error
            });

            await message.channel.send(`Now Playing: **${video.title}**.`);
        } else {
            message.channel.send('No results found.');
        }
    }
}

• avcodec/pthread_slice : Don't use static variable, fix race

  28 novembre 2020, par Andreas Rheinhardt

  avcodec/pthread_slice : Don't use static variable, fix race
  ff_slice_thread_init() uses a static variable to hold a function
  
  pointer, although the value of said pointer needn't be saved between
  
  different runs of this function at all.
  The reason for this being so is probably that said pointer points to
  
  a static function (if used) ; but storage class specifiers like "static"
  
  are not part of the type of an object and so including it in the pointer
  
  declaration is wrong (anyway, "static" means different things in both
  
  contexts : for the function declaration it affects linkage, for the
  
  variable storage duration).
  Using a static variable here can lead to races, e.g. when initializing
  
  VP9 (for which said function pointer was added) and H.264 with slice
  
  threading. The latter has the FF_CODEC_CAP_INIT_THREADSAFE flag set and
  
  is therefore unaffected by the lock guarding initializations of
  
  decoders.
