• 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 :)

  


• Problem compiling ffmpeg with nvenc using visual studio 2015 community edition

  23 février 2020, par Uri Raz

  I’m trying to build ffmpeg w/ nvenc on Windows 10 64 bit and visual studio 2015 community edition. The command from step 10 in the Using FFmpeg with NVIDIA GPU Hardware Acceleration doc :

  ./configure —enable-nonfree —enable-cuda-sdk —enable-libnpp –-toolchain=msvc —extra-cflags=-I../nv_sdk —extraldflags=-libpath :../nv_sdk

  Gives me the error ’Unknown option "–-toolchain=msvc"’

  Background : I’ve executed the commands (changed the path in the first, I’m not sure its right) :

  export PATH="/C/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.16.27023/bin/Hostx64/x64/" :$PATH
  export PATH="/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v10.0/bin/" :$PATH

  And ../nv_sdk has the subdirectories include & bin, copied from the NVIDIA GPU Computing Toolkit directory.

• h264dec : do not export the chroma sample location immediately on parsing the SPS

  h264dec : do not export the chroma sample location immediately on parsing the SPS
  This SPS is not necessarily the one that will be used. Export the chroma
  
  location along with all the other SPS properties.
