• 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 :)

  


• ffmpeg generated media segments dont work for http-live-streaming

  13 mars 2015, par Macmee

  I’m using this command :

  ffmpeg -i temp/B8B147C1-509A-4DB1-BDE3-0DD659A62D16.mp4 -acodec aac -strict experimental -vcodec libx264 -f mpegts pipe:1

  and my playlist looks something like :

  #EXT-X-VERSION:3
  
  #EXTM3U
  
  #EXT-X-TARGETDURATION:10
  
  #EXT-X-MEDIA-SEQUENCE:1
  
  
  
  #EXTINF:4.5,
  
  http://localhost:3008/stream/B8B147C1-509A-4DB1-BDE3-0DD659A62D16.ts
  
  #EXT-X-ENDLIST

  This works perfectly fine in VLC but not in itunes or iOS Safari. The video refuses to play. I need to be able to generate the .ts files from ffmpeg - cam I using the wrong encoding anywhere ?
