• I dont know how to Create a frame from a video with FFMpeg

  17 octobre 2017, par Rohallah Hatami

  by this code i am creating new object of news width video file and save that file into public/files

    public function store(Request $request, $type)
  
  { 
  
      $library_data = [
  
          'library_title' => request()->input('title'),
  
          'library_short_text' => request('short_text'),
  
          'library_body' => request('body'),
  
          'library_type' => $type,
  
          'library_cat_id' =>request()->input('category'),
  
      ];
  
  
  
      $new_library_object = Library::create($library_data);
  
      if (count($request->file('fileItem')) > 0 && is_array($request->file('fileItem')) ){
  
          foreach ($request->file('fileItem') as $file){
  
              $file_data=[
  
                  'file_type'=> $file->getMimeType(),
  
                  'file_size'=> $file->getClientSize(),
  
              ];
  
              $new_file_name = str_random(45).'.'.$file->getClientOriginalExtension();
  
              $result = $file->move(public_path('files'),$new_file_name);
  
              if($result instanceof \Symfony\Component\HttpFoundation\File\File){
  
                  $file_data['file_name'] = $new_file_name;
  
                  $file_data['file_title'] = $new_file_name;
  
  
  
                  $new_file_object=$new_library_object->files()->create($file_data);
  
  
  
              }
  
          }
  
      }elseif (count($request->file('fileItem')) > 0 && !is_array($request->file('fileItem'))){
  
  
  
          $file_data=[
  
              'file_type'=> $request->file('fileItem')->getMimeType(),
  
              'file_size'=> $request->file('fileItem')->getClientSize(),
  
          ];
  
  
  
  
  
          $new_file_name = str_random(45).'.'.$request->file('fileItem')->getClientOriginalExtension();
  
          $result = $request->file('fileItem')->move(public_path('files'),$new_file_name);
  
          if($result instanceof \Symfony\Component\HttpFoundation\File\File){
  
              $file_data['file_name'] = $new_file_name;
  
              $file_data['file_title'] = $new_file_name;
  
  
  
              $new_file_object=$new_library_object->files()->create($file_data);
  
  
  
          }
  
      }

  then I dont know how use this codes to Create a frame from a video

  FFMpeg::fromDisk('videos')
  
  ->open('steve_howe.mp4')
  
  ->getFrameFromSeconds(10)
  
  ->export()
  
  ->toDisk('thumnails')
  
  ->save('FrameAt10sec.png');

  whate is ’videos’ in fromdisk and in my codes how use this parametrs

  I use this code `

  $new_file_object=$new_library_object->files()->create($file_data);
  
              $start = \FFMpeg\Coordinate\TimeCode::fromSeconds(5);
  
              $clipFilter = new \FFMpeg\Filters\Video\ClipFilter($start);
  
              FFMpeg::fromDisk('files')
  
                  ->open($new_file_object->file_name)
  
                  ->addFilter($clipFilter)
  
                  ->export()
  
                  ->toDisk('files')
  
                  ->inFormat(new \FFMpeg\Format\Video\X264)
  
                  ->save('short_steve.mkv');

  but I have this erroe

  Non-static method Pbmedia\LaravelFFMpeg\FFMpeg::fromDisk() should not be called statically

  There is the part of my music bot in Discord, I don't really know why it doesn't work. Actually, I tried to use someone's old code, so it needs to be fixed. I have cut out the most important parts of the code, which most likely had an error.
I found other questions, but there was another errors.
After trying to start the video, I get the following errors :
[out#0/s16le @ 000002452f906a00] Output file does not contain any stream
Error opening output file pipe:1.

• FFmpeg pan filter error when routing stereo audio to rear channels of 5.1 output

  13 avril, par MilkyTech

  I'm trying to mix a stereo commentary track into the rear surround channels of a 5.1 audio stream using FFmpeg on Windows 10. My goal is to lower the volume of the original 5.1 movie audio, then add the stereo commentary so it plays from the rear left and right speakers (SL and SR).

  


  I've already converted the commentary to EAC3 to match the main track's codec :

  


  ffmpeg -i "CastCommentary.m4a" -c:a eac3 -b:a 640k CastCommentary.eac3

  


  Then I tried mixing them like this (from within Command Prompt, not PowerShell or a batch file) :

  


  ffmpeg -i "Tropic.Thunder.2008.UNRATED.mkv" -i "CastCommentary.eac3" -filter_complex "[0:a:0]volume=0.4[aud1]; [1:a:0]pan=5.1:FL=0:FR=0:FC=0:LFE=0:SL=c0:SR=c1[cm_rear]; [aud1][cm_rear]amix=inputs=2[aout]" -map 0:v -map "[aout]" -map 0:s? -t 600 -c:v copy -c:s copy -c:a eac3 -b:a 640k "Tropic.Thunder.5.1.commentary.test.mkv"


  


  But I keep getting errors like :

  


  [fc#0 @ ...] Error applying option 'SL' to filter 'pan': Option not found
Error : Option not found


  


  Or :

  


  [Parsed_pan_1 @ ...] Expected in channel name, got ""


  


  Or even :

  


  Output channel layout 5.1 does not match the number of channels mapped 2.


  


  I’ve tried variations of the pan syntax :

  


  

  • pan=5.1:FL=0:FR=0:FC=0:LFE=0:SL=c0:SR=c1

  


  • pan=5.1|FL=0|FR=0|FC=0|LFE=0|SL=c0|SR=c1

  


  • Wrapping in single/double

  


  • quotes Escaping for CMD (no caret issues in current runs)

  


  


  Nothing seems to work.

  


  🎯 Goal :

  


  

  • Keep 5.1 audio from the original movie (volume lowered)

  


  • Add stereo commentary to SL and SR

  


  • Output a proper 5.1 EAC3 mix

  


  


  🔧 System :

  


  

  • Windows 10

  


  • FFmpeg version : [latest static build from ffmpeg.org]

  


  • Running in true Command Prompt (not PowerShell)

  


  • Source audio : 5.1 EAC3 from a .mkv, stereo .eac3 from .m4a

  


  


  What’s the correct filter_complex syntax to route a stereo track to the rear channels of a 5.1 layout using FFmpeg on Windows ? Am I missing something about pan, amix, or Windows quirks ?
