• FFmpeg scale and overlay multiple images/gif on image in android issue ?

  4 décembre 2019, par Shweta Patil

  I am trying to place multiple images/gif on image. I had tried placing single gif on image or video and its working perfectly fine but not able to work with multiple images with simultaneous scaling. Tried below code but getting error :

          String[] command=new String[13];
  
          command[0]="-i";
  
          command[1]=input;
  
          command[2]="-i";
  
          command[3]=thumbnail2;
  
          command[4]="-i";
  
          command[5]=thumbnail;
  
          command[6]="filter_complex";
  
          command[7]="[0:v]scale=0:0[base]";
  
          command[8]="[1:v]scale=30:-1[img1]";
  
          command[9]="[2:v]scale=3000:-1[img2]";
  
          command[10]="[base][img1]overlay=70:70[tmp1]";
  
          command[11]="[tmp1][img2]overlay=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2[out]";
  
  
  
          command[12]="/storage/emulated/0/Pictures/logo-2000.gif";
  
          fFmpeg.execute(command,
  
                  new ExecuteBinaryResponseHandler() {
  
  
  
                      @Override
  
                      public void onStart() {
  
                          //for logcat
  
                          Log.w(TAG,"Cut started");
  
                      }
  
  
  
                      @Override
  
                      public void onProgress(String message) {
  
                         Log.w(TAG,message.toString());
  
                      }
  
  
  
                      @Override
  
                      public void onFailure(String message) {
  
  
  
                          Log.w(TAG,message.toString());
  
                          Toast.makeText(getApplicationContext(),"Error",Toast.LENGTH_SHORT).show();
  
  
  
                      }
  
  
  
                      @Override
  
                      public void onSuccess(String message) {
  
  
  
                          Log.w(TAG,message.toString());
  
                          Toast.makeText(getApplicationContext(),"sucessfully saved",Toast.LENGTH_SHORT).show();
  
                      }
  
  
  
                      @Override
  
                      public void onFinish() {
  
  
  
                          Log.w(TAG,"Cutting video finished");
  
                      }
  
                  });

  Error I am getting is :

  [NULL @ 0xb6591800] Unable to find a suitable output format for ’filter_complex’
  filter_complex : Invalid argument

  As I am new to ffmpeg please help me to resolve the issue I just want to scale and overlay multiple images simultaneously.

• 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 :)

  


• I need the script to work on all dav files

  4 décembre 2019, par audicom

  Script should run in recursive mode, find DAV files and start DAV to JPG conversions using FFMPEG. The script is working, identifying files in folders and starting conversions when DAV files exist, but is ignoring some DAV files.
  When I put these DAV files back in the folder it converts correctly.
  What could be wrong ?
  I thought it might be the speed of the process, since the files are being generated in the folder, the script must wait for the file to be closed and complete to act. I tried to delay the conversion process by 15 seconds using a PING, but it still skips some files.

  cd E:\VM01\1002
