• Why does it say error finding module when I already installed it

  13 mai 2020, par MiqhtieLol

  I am trying to code a discord music bot and this is my code :

  



  const config = require('config.json')
const Discord = require('discord.js');
const ffmpeg = require('ffmpeg-extra')
const client = new Discord.Client();

client.once('ready', () => {
    console.log('Ready!');
});
client.on('message', message => {
    if(message.content.toLocaleLowerCase() === "elevator"){
        if(message.member.voice.channel){
            message.channel.send("Thanks to https://www.bensound.com for supplying us with this music.")
            play(message.member.voice.channel)
        }
        else {
            message.channel.send("Yo, please join a VC first.")
        }
    }
});

async function play(voiceChannel) {
    const connection = await voiceChannel.join();
    connection.play('elevator.mp3');
}

client.login(config.token);


  



  For some reason even though I installed ffmpeg via npm install ffmpeg it says :

  



  Error: Cannot find module 'ffmpeg-extra'


  



  EDIT : When I use const ffmpeg = require("ffmpeg") I get this error :

  



  UnhandledPromiseRejectionWarning: Error: FFmpeg/avconv not found!


  


• Waiting between FFMPEG scripts when creating .hdr/.chk and .mpd files on NGINX server using RTMP module

  17 avril 2020, par Mathew Knight

  Wonder if anyone might be able to suggest a solution to and issue i'm having.

  



  I'm running some FFMPEG scripts inside a RTMP server block on an NGINX server running on Ubuntu 18.04.

  



  Basically i'm ingesting the RTMP stream to the server then using FFMPEG to Demux into separate audio and video header and chunk files, then in separate scripts i'm creating two separate manifests for both the audio and video.

  



  The player i have (a development ambisonic, 360 video player) is having problems reading the stream correctly and i believe this is due to the FFMPEG process for the manifests not waiting 2 seconds before running.

  



  Is there a way to program a wait in between the scripts to facilitate this ?

  



  furthermore, is there a way to make the manifest scripts only run once then quit ?

  



  heres my current NGINX .conf
