• Downloader downloads high quality video but muted

  5 avril 2023, par Stef-Lev

  I have created a next.js video downloader and I want to download videos of the highest quality. When I trigger the download I only get a muted mp4 file (in high quality) and a muted mp3 file. Here is the api file. How could I download the video, the audio and then merge them with ffmpeg correctly ?

  


  import ytdl from "ytdl-core";
import fs from "fs";
import { Server } from "socket.io";
import ffmpeg from "fluent-ffmpeg";

export default async function handler(req, res) {
  if (res.socket.server.io) {
    console.log("Socket is already running");
    res.end();
    return;
  }
  console.log("Socket is initializing");
  const io = new Server(res.socket.server);
  res.socket.server.io = io;

  io.on("connection", async (socket) => {
    console.log(socket.id, "socketID");

    const sendError = async (msg) => {
      socket.emit("showError", msg);
    };

    const sendProgress = async (msg) => {
      console.log(msg);
      socket.emit("showProgress", msg);
    };

    const sendComplete = async (msg) => {
      console.log(msg);
      socket.emit("showComplete", msg);
    };

    const downloadVideo = async (url) => {
      try {
        const videoInfo = await ytdl.getInfo(url);
        const outputPath = path.join(
          process.cwd(),
          "mp4s",
          `${videoInfo.videoDetails.title}.mp4`
        );
        const audioPath = path.join(
          process.cwd(),
          "mp4s",
          `${videoInfo.videoDetails.title}.mp3`
        );

        const videoFormat = ytdl.chooseFormat(videoInfo.formats, {
          quality: "highestvideo",
          filter: "videoonly",
        });
        const audioFormat = ytdl.chooseFormat(videoInfo.formats, {
          quality: "highestaudio",
          filter: "audioonly",
        });
        const videoStream = ytdl(url, { quality: videoFormat.itag });
        const audioStream = ytdl(url, { quality: audioFormat.itag });

        const videoOutput = fs.createWriteStream(outputPath);
        const audioOutput = fs.createWriteStream(audioPath);

        audioStream.pipe(audioOutput);
        videoStream.pipe(videoOutput);

        let downloadedBytes = 0;
        let totalBytes =
          videoFormat.contentLength || videoInfo.length_seconds * 1000000;

        videoOutput.on("data", (chunk) => {
          downloadedBytes += chunk.length;
          const progress = Math.round((downloadedBytes / totalBytes) * 100);
          sendProgress({ progress });
        });

        videoOutput.on("error", (err) => {
          console.error(err);
          sendError({
            status: "error",
            message: "An error occurred while writing the video file",
          });
        });

        audioOutput.on("error", (err) => {
          console.error(err);
          sendError({
            status: "error",
            message: "An error occurred while writing the audio file",
          });
        });

        videoOutput.on("finish", () => {
          audioOutput.on("finish", () => {
            if (fs.existsSync(outputPath) && fs.existsSync(audioPath)) {
              const outputFile = path.join(
                process.cwd(),
                "mp4s",
                `${videoInfo.videoDetails.title}-with-audio.mp4`

              const command = ffmpeg()
                .input(outputPath)
                .input(audioPath)
                .outputOptions("-c:v copy")
                .outputOptions("-c:a aac")
                .outputOptions("-b:a 192k")
                .outputOptions("-strict -2")
                .output(outputFile)
                .on("end", () => {
                  fs.unlink(outputPath, () => {});
                  fs.unlink(audioPath, () => {});
                  sendComplete({

  I am also using socket.io to show the progress in the frontend, but for some reason I don't get the progress correctly. Is it possible to do that ?

• Piwik 2 reaches end of life soon (December 2017), update now !

  7 décembre 2017, par Piwik Core Team — Community

  In less than three weeks, Piwik 2 will be no longer supported. This means that no further (security) updates will be released for this version. As per our Long Term Support announcement, Piwik 2.X is supported for 12 months after the initial release of Piwik 3.0.0 which was on December 18th 2016. Therefore, Piwik 2 will no longer receive any updates after December 18th 2017.

  It has been almost a year since we released Piwik 3 and we highly recommend updating to Piwik 3 ASAP. The major new release came with a new UI, performance and security improvements. If you are still on Piwik 2, the security improvements alone should be worth updating your Piwik to Piwik 3 now. We cannot recommend this enough.

  The update to Piwik 3 should be smooth, but may take a while depending on the amount of data you have.

  • If you have any problem with the update, feel free to get in touch with us, or ask in the forums.
  • If you are currently using Piwik self-hosted and would like to be upgraded, plus your Piwik managed in the official Cloud-hosted service, contact InnoCraft Cloud and they will migrate your database.

  At Piwik and InnoCraft, the company of the makers of Piwik, we have seen many thousands of Piwik installations upgraded over the past year and look forward to an exciting future for Piwik 3 and beyond !
