• Node.js - I keep getting the following error : Error : ffmpeg stream : write EPIPE

  14 août 2020, par Kyky

  I'm currently programming a Discord bot using discord.js, and I'm using ytdl-core to play music. Here is the program I'm using to play music :

  



  const {google} = require('googleapis');
const ytdl = require('ytdl-core');
// Initialise Google API
const youtube = google.youtube({
    version: 'v3',
    auth: MyAuth
});
musicQueue = [] // Queue for playing music
dispatcher = null; // Transmits voice packets from stream

module.exports = {
    name: "play",

    async execute(msg, args) { // msg is a Discord Message
        // Play music and music queued after
        async function playAndQueue(stream) {

            // Join voice channel
            voiceChannel = client.channels.cache.find(channel => channel.type === "voice" && channel.name === "music-channel");
            voiceConnection = voiceChannel.join();

            dispatcher = await voiceConnection.play(stream, {volume: 0.3}); // Decrease volume to prevent clipping

            // When music stops
            dispatcher.on("finish", async reason => {
                if (musicQueue[0]) { // Still have music queued
                    const nextVideoLink = musicQueue[0]; // Next video to play
                    const stream = ytdl(nextVideoLink, {filter: 'audioonly'});

                    playAndQueue(stream);
                    dispatcherInfo = await ytdl.getInfo(nextVideoLink);
                    musicQueue.shift();
                } else { // No music to play
                    dispatcher = null;
                    dispatcherInfo = null;
                }
            });

            dispatcher.on("error", console.log);
            dispatcher.on("debug", console.log);

        }

        // Search Youtube using args
        const youtubeSearchResult = await youtube.search.list({
            part: 'snippet',
            type: 'video', // We do not want channels or playlists
            q: args.join(' '),
            maxResults: 1 // We only need first search result
        });
        const youtubeVideo = youtubeSearchResult.data.items[0];
        if (! youtubeVideo) {
            msg.channel.send("Error: Could not find any music matching search.");
            return;
        }

        const videoLink = `https://www.youtube.com/watch?v=${youtubeVideo.id.videoId}`; // Link to video

        const stream = ytdl(videoLink, {filter: 'audioonly'});
        const videoInfo = await ytdl.getInfo(videoLink);


        if (dispatcher) { // Currently playing music
            musicQueue.push(videoLink);
            msg.channel.send(`**${videoInfo.title}** has been added into the queue!`);
        } else {
            playAndQueue(stream);
            dispatcherInfo = videoInfo;
            msg.channel.send(`Currently playing **${videoInfo.title}**!`);
        }
    }
}


  



  However, when I try to run the program on Heroku, I get this error :

  



  ffmpeg stream: write EPIPE
    at WriteWrap.onWriteComplete [as oncomplete (internal/stream_base_commons.js:92:16) {
  errno: 'EPIPE',
  code: 'EPIPE',
  syscall: 'write'
}


  



  What can I do ?

  


• Error in http dynamic streaming TypeError - Error #1009

  25 octobre 2014, par internetdoping

  I am making mutli-bitrate streaming in FMS and FFMPGE.
  In FFMPEG I create 4 bitrates of source video and publish it on the FMS through RTMP protocol (rtmp://my-server/livepkgr/mystreamName1?adbe-live-event=liveevent).

  Now all configurations are working currently but sometimes I get this error :
  1- TypeError - Error #1009
  

  This is my FFMPEG syntaxt to create multi-bitrate :

  ffmpeg -re -i j:\movie\warz.mkv

• Parse folder name, generate GIF from images inside using ffmpeg

  16 janvier 2023, par BestMordaEver

  I have 150 folders with some nasty folder structure. Inside are animation frames helpfully named 1.png, 2.png and so on. I need to generate gifs from those images and have them named properly. Here's how I'd handle this case by case :

  


  Folder ./dragon/raw/bodies/dragon/green/old/5/down/idle has 25 .png files. I run the following commands :

  


  # pngs to gif
ffmpeg -framerate 12 -start_number 1 -i ./dragon/raw/bodies/dragon/green/old/5/down/idle/%d.png dragon-green-old-5-down-idle-intermediate.gif

# gif to boomerang gif
ffmpeg -i dragon-green-old-5-down-idle-intermediate.gif -filter_complex "[0]trim=start_frame=1:end_frame=29,setpts=PTS-STARTPTS,reverse[r];[0][r]concat=n=2:v=1:a=0,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" dragon-green-old-5-down-idle.gif

# remove the intermediate gif
rm dragon-green-old-5-down-idle-intermediate.gif


  


  Note : relevant part of the name for gif is whatever's after /raw/bodies

  


  Question : how do I put this in a loop that would iterate over all the nested folders, parse their names and feed the result in the commands above ?

  


  Bonus question : is there a way to merge the two commands and create the boomerang gif immediately, removing the need in intermediate files ?
