• ERROR in ./node_modules/fluent-ffmpeg/index.js Module not found : Error : Can't resolve './lib-cov/fluent-ffmpeg'

  When I do yarn add fluent-ffmpeg i get this issue :

  They said they fixed it in this GitIssue : here

  



  Anyone have any advice ?

• 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 :)

  


• Connecting ffmpeg java module to named pipe

  27 novembre 2019, par Ehsan5

  I want to extract the output of folowing ffmpeg Module with the help of Named pipe. I am currently having problems with communication of ffmpeg and named pipe, but thank you for explaining how to extract stream bytes from output named pipe and convert it to images.

  My code gives socket connection error when using named pipe. I have used method that suggested in ffmpeg main page (pipe:0 for input and pipe:1 for output) but because it is not named pipe I cannot use it in the client side. It should be noted that named pipe is opened successfully with jna win32 module.

  This is server side code(but i tested it with \\.\pipe\PIPE also) :

  FFmpegBuilder builder = new FFmpegBuilder()
  
  .setInput(input.getPath())
  
  .addOutput(" -f avi pipe:1 ")
  
  .addExtraArgs(videoFilterStr)
  
  .done();
  
  UUID caller = UUID.randomUUID();
  
  try {FFmpegHelper.builder().progressListener().build().run(builder, caller)...
