    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, /dev/video0, -f decklink

    20 mars 2019, par Camille Goudeseune

    I’m trying to capture video from a PCI card, the Blackmagic DeckLink Mini Recorder, via ffmpeg, on a headless host running Ubuntu 18.04.2 LTS, hopefully with a command like

    ffmpeg -f decklink -i /dev/video0 ...

    How can I make that work ? I have two obstacles.

    No /dev/video0

    ffmpeg -i /dev/video0 ... fails : /dev/video0: No such device or address.
    v4l2-ctl --list-devices fails with the same error message.

    I built /dev/video0, and it looks okay :

    mknod /dev/video0 c 81 0
    
chown root.video /dev/video0
    
chmod g+rw /dev/video0

    To compare this file with a working one, I ran strace cat /dev/video0 on this host, and on another host (Ubuntu 14) with a working /dev/video0. The outputs began to differ here (good, then bad) :

    fstat(1, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
    
open("/dev/video0", O_RDONLY)           = 3  
    
fstat(3, {st_mode=S_IFCHR|0660, st_rdev=makedev(81, 0), ...}) = 0
    
fadvise64(3, 0, 0, POSIX_FADV_SEQUENTIAL) = 0
    
----
    

    
fstat(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
    
openat(AT_FDCWD, "/dev/video0", O_RDONLY) = -1 ENXIO (No such device or address)

    So /dev/video0 is broken at a level lower than ffmpeg or v4l2 or even cat.

    On Ubuntu 14, man 8 MAKEDEV suggests that the error message means that "the kernel does not have the driver configured or loaded."

    This Ubuntu 18 host lacks that manpage, but it does have a few /snap/core/*/sbin/MAKEDEV, all the same, so I tried

    /snap/core/6350/sbin/MAKEDEV -n -v video

    It would have created over a hundred devices videoXX, radioXX, vtxXX, vbiXX. Those devices didn’t exist yet, so it seemed harmless to try it.

    rm /dev/video0; /snap/core/6350/sbin/MAKEDEV video

    That rebuilt /dev/video0, but "No such device" remains, from cat or ffmpeg.

    No decklink

    ffmpeg -f decklink ... fails with Unknown input format: 'decklink'.

    Neither black nor deck nor link is mentioned by ffmpeg -devices (fbdev, lavfi, oss, v4l2) and ffmpeg -formats (about 350), either for Ubuntu’s own version 3.4.4-0ubuntu0.18.04.1, or for version N-93330-g7ff89574c7 compiled from source on 2019 Mar 13 :

    git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
    
cd ffmpeg
    
./configure --enable-nonfree --disable-doc --disable-w32threads --enable-pthreads

    (Although ./configure --help mentions --enable-decklink, using that yielded "ERROR : DeckLinkAPI.h not found." updatedb &amp;&amp; locate DeckLinkAPI.h finds no file with that name, either.)

    The DeckLink PCI card is recognized by hwinfo and lspci.

    lsmod reports the loaded modules blackmagic and blackmagic_io.

    Maybe the PCI card is installed ok, but ffmpeg just can’t reach it because I can’t configure it for that.

    Edit : Rebooting didn’t fix anything.
