  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

    I would like to know which directory I should put FFmpeg.

    


    I would also like to know if the FFmpeg executable has to be in a folder or compressed or if i can just place the executable in a certain directory

    


    I am hosting my bot using Heroku on a Mac using Discord.js V12

    


    Please help.

    


    Thanks !

    


  • Discord bot returning odd error message and not playing sound

    26 février 2020, par Ravenr_

    I am attempting to create a function of my discord bot that will join your voice channel then play something from youtube as specified in the command

    i.e. $play <youtube link="link"></youtube>

    The problem is that my bot joins the voice channel but doesn’t play any sound and outputs an error to the console that I dont know how to fix

    My Code :

    const ytdl = require("ytdl-core");
    
module.exports = {
    
    name: 'play',
    
    description: 'initiates music methods of the bot',
    
    execute(msg, args){
    
        var servers = {};
    

    
        function play(connection, msg){
    
            var server = servers[msg.guild.id];
    

    
            server.dispatcher = connection.playStream(ytdl(server.queue[0], {filter: "audioonly"}));
    
            server.queue.shift();
    

    
            server.dispatcher.on("end", function(){
    
                if(server.queue[0]){
    
                    play(connection, msg);
    
                }else{
    
                    connection.disconnect();
    
                }
    
            });
    

    

    
        }
    
        if(!args[1]){
    
            return msg.channel.send("you need to provide a link");
    
        } 
    
        if(!msg.member.voiceChannel){
    
            return msg.channel.send("You must be in a voice channel to use this feature");

    for reference these are the links I tested it with 1 & 2

    I’m not sure how to make queue[0] a string, which is what I assume the problem is.

    I was thinking of using a toString() i.e. server.queue[0].toString() but I think that will just return the memory address.

    If anyone can help me know what the issue is or how to fix it, that would be great.

  • ffmpeg : Extract unknown data stream from video container

    23 juillet 2020, par Pikkostack

    I have a .MOV container which contains the following tracks :

    &#xA;

    Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 3840x2160 [SAR 1:1 DAR 16:9], 100619 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc (default)&#xA;Metadata:&#xA;  creation_time   : 2020-07-21T22:48:24.000000Z&#xA;  handler_name    : DJI.AVC&#xA;  encoder         : AVC encoder&#xA;Stream #0:1(eng): Data: none (priv / 0x76697270), 87 kb/s&#xA;Metadata:&#xA;  creation_time   : 2020-07-21T22:48:24.000000Z&#xA;  handler_name    : DJI.Meta&#xA;Stream #0:2(eng): Subtitle: mov_text (text / 0x74786574), 2 kb/s (default)&#xA;Metadata:&#xA;  creation_time   : 2020-07-21T22:48:24.000000Z&#xA;  handler_name    : DJI.Subtitle&#xA;

    &#xA;

    As you can see, stream #0:1, called DJI.meta, is of an unknown data format. I just want to extract the raw data of this stream to a file. So that is the ffmpeg command I tried :

    &#xA;

    ffmpeg -i .\DJI_0001.MOV -map 0:1 metadata&#xA;

    &#xA;

    But using this command results in the following error :

    &#xA;

    Unable to find a suitable output format for &#x27;metadata&#x27;&#xA;metadata: Invalid argument&#xA;

    &#xA;

    How can I tell ffmpeg that the data should not be formated, so that only the raw data is extracted ?

    &#xA;
