• FFMPEG File Output is Still in Use By a Process

  4 août 2021, par Tyler Bacon

  I am trying to complete this part of my program. In this section, I am trying to speed up or slow down a video based on a factor variable. Once it's done, I use moviepy to turn it into a VideoFileClip, then I delete the file.

  


      if factor <= 2:
        system("ffmpeg -i " + paths[dex] + " -vf setpts=" + str(vfactor) + "*PTS -an ./Media/Videos/temp.mp4")
        system("ffmpeg -i " + paths[dex] + " -filter:a atempo=" + str(factor) + " -vn ./Media/ShortSounds/temp.mp3")
    elif 2 < factor < 4:
        factor = round(sqrt(factor), 1)
        system("ffmpeg -i " + paths[dex] + " -vf setpts=" + str(vfactor) + "*PTS,setpts=" + str(vfactor) + "*PTS  -an ./Media/Videos/temp.mp4")
        system("ffmpeg -i " + paths[dex] + " -filter:a atempo=" + str(factor) + ",atempo=" + str(factor) + " -vn ./Media/ShortSounds/temp.mp3")
    elif factor > 4:
        raise Exception("File " + paths[dex] + " is too long.")
    t = VideoFileClip("./Media/Videos/temp.mp4")
    t.audio = AudioFileClip("./Media/Videos/temp.mp3")
    templist.append(t)
    remove("./Media/Videos/temp.mp4")


  


  However, when the code gets to the deletion command, it has the following error :

  


  PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: './Media/Videos/temp.mp4'


  


  What's strange is, I can see the temp.mp4 file, and it runs just fine. I never get this error while manually running the temp.mp4 file.

  


  I have tried the following :

  


  

  • Waiting 5, 10, and 20 seconds before deleting the file.

  


  • Running "taskkill -f -im ffmpeg.exe" before deleting the file

  


  • I went through the debugger, and right before the deletion, I checked in task manager to see if ffmpeg was still running, and it wasn't.

  


  


  Do you guys have any idea what could be holding this up ? My code worked previously when I was trying to just do audio, but I am trying it with video and this is happening.

  


• Laravel Spatie - Spatie\MediaLibrary\Jobs\PerformConversions Job Failed

  5 février 2019, par Tout Nu Les Chinois

  I have an issue with Laravel Spatie’s media conversion OR Redis.

  I’m working in TDD, so all my test passed success, even conversion.
  For an input file sample.flv I have my files as expected..

  But when perform integration test my Jobs failed when they are queued.. (redis) And I have no logs.....

  Do you already have trouble with jobs and conversion ?

  job chained failed

  I am Using Laravel Spatie and Laravel-ffmpeg.

  The chained job

  ProcessPost::withChain([
  
              new AssociateMedias($post, $filenames),
  
              new AssociateTags($post, $tags, $user),
  
              new ActivatePost($post),
  
              new AttributeBadge('post', $user),
  
              new UpdateScore(100, $user)
  
          ])->dispatch($post)->allOnQueue('default');

  Here my Assoc Job

  public function handle()
  
      {
  
          array_map(function($name){
  
              $this->mediable->associate(UploadFiles::getTempDir() . $name);
  
          }, $this->filenames);
  
      }

  Here the assoc function in my Media trait

     /**
  
       * @param $path
  
       * @return Media
  
       * @throws DiskDoesNotExist
  
       * @throws FileDoesNotExist
  
       * @throws FileIsTooBig
  
       */
  
      public function associateVideo($path){
  
          $media = $this->addMedia($path)
  
                        ->toMediaCollection('videos');
  
  
  
          VideoConverter::toHls(
  
              'public',
  
              $media->originalPath(),
  
              $media->streamPath()
  
          );
  
  
  
          VideoConverter::toMp4(
  
              'public',
  
              $media->originalPath(),
  
              $media->downloadPath()
  
          );
  
  
  
          Storage::disk('public')->delete($media->originalPath());
  
  
  
          return $media;
  
      }

  And here my Conversion lib

  static function toMp4($disk, $path, $to) {
  
          $lowBitrateFormat = (new X264('aac'))->setKiloBitrate(500);
  
  
  
          FFMpeg::fromDisk($disk)
  
              ->open($path)
  
              ->addFilter(function ($filters) {
  
                  $filters->resize(new Dimension(960, 540));
  
              })
  
              ->export()
  
              ->inFormat($lowBitrateFormat)
  
              ->save($to);
  
      }

• How to streaming audio with ffmpeg and container of my own choosing ? [closed]

  2 octobre 2024, par xchg.ca

  I'm streaming an ac3 audio via rtsp using ffmpeg like this :

  


  > ffmpeg -re -f ac3 -i sample4.ac3 -ar 8000 -f mulaw -f rtsp rtsp://10.22.22.11:8554/audiostream


  


  In the RTSP protocol exchange it DESCRIBEd like this :

  


  > Session Description Protocol
>     Session Description Protocol Version (v): 0
>     Owner/Creator, Session Id (o): - 0 0 IN IP4 127.0.0.1
>     Session Name (s): No Name
>     Connection Information (c): IN IP4 0.0.0.0
>     Time Description, active time (t): 0 0
>     Media Description, name and address (m): audio 0 RTP/AVP 96
>     Media Attribute (a): control:rtsp://10.22.22.11:8554/audiostream/trackID=0
>     Media Attribute (a): rtpmap:96 mpeg4-generic/8000/2
>     Media Attribute (a): fmtp:96 config=1590; indexdeltalength=3; indexlength=3; mode=AAC-hbr; profile-level-id=1; sizelength=13;
> streamtype=5


  


  I wondering if I can specify specific container in ffmpeg command line while keeping media format the same. For example I want MPEG-TS container instead of mpeg4. Looking through the ffmpeg docs did not really helped me.
