• Ask Help for Reproduce AccMPEG coded by Du Kuntai

  30 novembre 2022, par censhallwe

  Here is his github : https://github.com/KuntaiDu/AccMPEG
When I follow his steps to reproduce AccMPEG, I meet some problems. It's my first time to reproduce others' paper. When I set up the conda environment, the conda_env.yml has some pip errors and stop like picture1 :
  
PIC 1.
  
So I change its name to accmpeg (originally diff) and delete some code about torch/torchvision/torchaudio/detectron2. After setup the environment, I run generate_mpeg_curve.py and meet some errors like picture2 :
  
PIC 2.
  
Maybe I failed to setup the environment. And when I run batch_blackgen_roi.py, I meet some errors like these :
  
IMG 3.
  
I search accmpeg and want to try to find solution from the Internet. But I don't get useful information. Therefore, I try to seek help. If you can give me a hand, I am very grateful.
  
If you can reproduce it well, please teach me how to operate. It's better if you have some useful pictures.Thanks very much !

  


• How can I fix video processing and 500 Error - (Laravel, FFmpeg)

  19 juillet 2019, par San Martín Figueroa Pablo

  I’m setting up a new website with Laravel for uploading videos...
  I have read all the possible solutions but none of them help me to solve the issue...

  This is my issue : When I upload a small file (<10mb) the web works fine, the video get uploaded and the video get converted, the dashboard shows the converted videos---

  When I try to upload a large file, the file get uploaded, the video get converted with a green frame on it (really uggly) and the site goes to a 500 server error...

  I’m using Laravel Jobs to do the conversion.

  My Controller code :

      <?php
  
  
  
      namespace App\Http\Controllers;
  
  
  
      use Illuminate\Http\Request;
  
      use Illuminate\Support\Facades\DB;
  
      use Illuminate\Support\Facades\Storage;
  
      use Symfony\Component\HttpFoundation\Response;

      use Closure;
  
      use App\Jobs\ConvertVideoForPreview;
  
      use FFMpeg\FFProbe;
  
      use FFMpeg\Coordinate\Dimension;
  
      use FFMpeg\Format\Video\X264;
  
      use Pawlox\VideoThumbnail\Facade\VideoThumbnail;
  
      use Pbmedia\LaravelFFMpeg\FFMpegFacade as FFMpeg;
  
      use Illuminate\Contracts\Filesystem\Filesystem;
  
  
  
  
  
      use App\Video;
  
  
  
      class VideoController extends Controller
  
      {
  
      public function createVideo(){
  
          return view('video.createVideo');   
  
      }
  
      public function saveVideo(Request $request){
  
  
  
  
  
          set_time_limit(0);
  
          ini_set('memory_limit', '1024M');
  
  
  
          //Validar Formulario
  
  
  
          $validatedData = $this -> validate($request, [
  
  
  
              'title' => 'required',
  
              'description' => 'required',
  
              'palabras' => 'required',
  
              'video' => 'mimetypes:video/mp4,video/quicktime'
  
  
  
  
  
          ]);
  
  
  
          $video = new Video();
  
          $user = \Auth::user();
  
          $video -> user_id = $user->id;

          if($video_file){
  
  
  
          $video_path = 'original'.'_'.$video_file ->                                 
  
          getClientOriginalName();
  
          Storage::disk('videos')-> put($video_path, 
  
          \File::get($video_file));
  
  
  
          $videoUrl = storage_path('app/videos/').$video_path;
  
          $storageUrl = storage_path('app/thumbs/');
  
          $fileName = 'thumb'.'_'.time().'.jpg';
  
          $second = 2;
  
  
  
          VideoThumbnail::createThumbnail($videoUrl, $storageUrl,     
  
          $fileName, $second, $width = 640, $height = 480);
  
  
  
          $video -> preview = $fileName;
  
          $video -> video_path = $video_path;
  
  
  
        }
  
          $video -> save();
  
  
  
          ConvertVideoForPreview::dispatch($video);
  
  
  
          return redirect() -> route('home')
  
                            -> with (array(
  
              'message' => 'El video se ha enviado con exito'));
  
        }
  
  
  
          public function getImage($filename){
  
  
  
              $file = Storage::disk('thumbs') -> get($filename);
  
              return new Response($file, 200);
  
        }
  
  
  
          public function getVideo($filename){
  
  
  
              $file = Storage::disk('converted_videos') ->   
  
          get($filename);
  
              return new Response($file, 200);
  
        }
  
  
  
        }

  This is my ConvertVideo Job :

      <?php
  
  
  
       namespace App\Jobs;
  
  
  
       use App\Video;
  
  
  
       use Carbon\Carbon;
  
       use FFMpeg;
  
       use FFMpeg\Format\Video\X264;
  
  
  
       use Illuminate\Http\Request;
  
       use Illuminate\Bus\Queueable;
  
       use Illuminate\Queue\SerializesModels;
  
       use Illuminate\Queue\InteractsWithQueue;
  
       use Illuminate\Contracts\Queue\ShouldQueue;
  
       use Illuminate\Foundation\Bus\Dispatchable;
  
  
  
       class ConvertVideoForPreview implements ShouldQueue
  
  
  
          {
  
            use Dispatchable, InteractsWithQueue, Queueable, 
  
            SerializesModels;
  
  
  
            public $video;
  
  
  
  
  
            public function __construct(Video $video)
  
           {
  
               $this -> video = $video;
  
           }
  
            public function handle()
  
           {
  
  
  
            $converted_name= 'preview'.'-'.$this -> video -> 
  
            video_path.'.mp4';
  
  
  
            FFMpeg::open('videos/'.$this -> video -> video_path)
  
  
  
                          -> export()
  
                  -> inFormat(new \FFMpeg\Format\Video\X264)
  
                      -> save('converted_videos/'.$converted_name); 
  
  
  
              $this -> video -> update([
  
              'video_preview' => $converted_name,
  
              'processed' => true
  
               ]);
  
        }
  
       }

  One of my goals is to upload large video files (<=4GB), show a uploading process bar and a encoding process bar during the video upload.

  I getting this error :

   [core:error] [pid 14787:tid 139975366489856] [client 
  
    201.188.26.12:51022] Script timed out before returning headers: 
  
    index.php, 

  It’s happend when the video es proccesing and the redirect to home dashboard it’s call...

  The FFMPEG works :

  [2019-07-19 17:20:41] local.INFO: ffprobe executed command successfully  
  
  [2019-07-19 17:21:52] local.INFO: ffmpeg executed command successfully

  I have tried : Change all the memory and file size in PHP.ini, Nginx, Apache... (Probably I’m missing one)...

  Changed timeouts too.

  My environment : VPS 4GB 50GB, APACHE 2.4, PHP7.3, MySql MariaDB, WebServer : Apache-Nginx, Laravel 5.8.

  Can anyone help me to reach this ?...

  This is how the large video looks after converted and show 500 error in the browser :
  Error video processed

• Recommendataions for robust and invisible video watermarking software / library [on hold]

  1er mars 2014, par id128

  I am doing a research project in search of a robust and invisible video watermarking software / library (preferably in C++). It needs to meet the following requirements :

  • Robust - that is the watermark needs to survive common transformations such as re-encoding, A/D / D/A conversion, luminance/color change, shift, and crop (both in size and length)'

  • Invisible - to the human eye

  The watermark does not need to carry too much data - maybe a 64-bit UUID - and can be temporal or spatial. But I will need the ability to determine the existence (or not) of the watermark with only a few seconds of the video

  Some research I have done so far :

  • JAWS research paper (http://pdf.aminer.org/000/316/002/the_viva_project_digital_watermarking_for_broadcast_monitoring.pdf) but cannot find any implementations on the web and the authors are not responding to emails. Plus, that research is over 10 years old and I am hoping for something more modern.

  • OpenPuff - does not satisfy the robustness requirement in that the resulting video does not survive transformations.

  • ffmpeg software - I have figured out how to overlay a visible watermark, but that does not satisfy the invisibility requirement.

  Any ideas / suggestions / pointers will be awesome. Thanks.
