• The problem of code that generated typescript (node-fluent-ffmpeg module)

  10 décembre 2022, par Steve Rock

  This is my typescript code :

  



  import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { FfmpegCommand } from 'fluent-ffmpeg'

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  let test

  try {
    test = new FfmpegCommand('./adventure.mkv');
  } catch (error) {
    console.log(error);

  }

  await app.listen(3000);
}

bootstrap();


  



  Generated Javascript code :

  



  "use strict";
var __awaiter = (this && this.__awaiter) || function (thisArg, _arguments, P, generator) {
    function adopt(value) { return value instanceof P ? value : new P(function (resolve) { resolve(value); }); }
    return new (P || (P = Promise))(function (resolve, reject) {
        function fulfilled(value) { try { step(generator.next(value)); } catch (e) { reject(e); } }
        function rejected(value) { try { step(generator["throw"](value)); } catch (e) { reject(e); } }
        function step(result) { result.done ? resolve(result.value) : adopt(result.value).then(fulfilled, rejected); }
        step((generator = generator.apply(thisArg, _arguments || [])).next());
    });
};
Object.defineProperty(exports, "__esModule", { value: true });
const core_1 = require("@nestjs/core");
const app_module_1 = require("./app.module");
const fluent_ffmpeg_1 = require("fluent-ffmpeg");
function bootstrap() {
    return __awaiter(this, void 0, void 0, function* () {
        const app = yield core_1.NestFactory.create(app_module_1.AppModule);
        let test;
        try {
            test = new fluent_ffmpeg_1.FfmpegCommand('./adventure.mkv');
        }
        catch (error) {
            console.log(error);
        }
        yield app.listen(3000);
    });
}
bootstrap();
//# sourceMappingURL=main.js.map


  



  When I run this application I've next error :

  



  main.ts:12
message :"fluent_ffmpeg_1.FfmpegCommand is not a constructor"
stack :"TypeError : fluent_ffmpeg_1.FfmpegCommand is not a constructor\n at c :\nest\dist\src\main.js:20:20\n at Generator.next ()\n at fulfilled (c :\nest\dist\src\main.js:5:58)\n at process._tickCallback (internal/process/next_tick.js:68:7)\n at Function.Module.runMain (internal/modules/cjs/loader.js:834:11)\n at startup (internal/bootstrap/node.js:283:19)\n at bootstrapNodeJSCore (internal/bootstrap/node.js:622:3)"

  



  That's beacause this raw test = new fluent_ffmpeg_1.FfmpegCommand('./adventure.mkv'). When I change this on just test = new fluent_ffmpeg_1('./adventure.mkv') I haven't the error. Do you know how to fix it. If you know where are ffmpeg exapmles on typescript please share with me :)

  


• YouTube - MP4 to MP3 messes up

  23 novembre 2019, par theeSpark

  It’s supposed to download all the videos in the playlist and convert them to mp3. But all this does is make the mp4’s and 1 empty mp3 with a number higher than the max mp4. My newbie brain doesn’t know how to fix this...

  var ytpl = require('ytpl');
  
  var fs = require('fs-extra');
  
  var path = require('path');
  
  var ffmpeg = require('fluent-ffmpeg');
  
  var binaries = require('ffmpeg-static');
  
  var ytdl = require('ytdl-core');
  
  
  
  var output_dir = path.join(__dirname+"/dl");
  
  
  
  ytpl("PL8n8S4mVUWvprlN2dCAMoIo6h47ZwR_gn", (err, pl) => {
  
      if(err) throw err;
  
  
  
      let c = 0;
  
  
  
      pl.items.forEach((i) => {
  
          ytdl(i.url_simple+"", { filter: 'audioonly' }).pipe(fs.createWriteStream(output_dir+"/"+c+".mp4")).on('finish', () => {
  
              console.log("Finished MP4 DL, starting conversion...");
  
              ffmpeg(output_dir+"/"+c+".mp4")
  
                  .setFfmpegPath(binaries.path)
  
                  .format('mp3')
  
                  .audioBitrate(320)
  
                  .output(fs.createWriteStream(output_dir+"/"+c+".mp3"))
  
                  .on('end', () => {
  
                      console.log("Finished MP3 Convert...");
  
                  })
  
                  .run();
  
          });
  
          c++;
  
      });
  
  
  
  });
