• cant upload a .webm file after recording

  14 octobre 2017, par Syed Abdur Rehman Kazmi

  I kinda seem to stuck on something. I am missing something i dont know. I have uploaded a lot of files but somehow when i recorded this file via my laptop camera browser and try to upload it.. it doesnt.. I am also using ffmpeg to convert it.

  Laravel 5.4
  vuejs
  ffmpeg

  These are the tools involved the error i am getting is the file doesnt exist in local temp folder. ( i have checked it IS NOT there i dont understand why )

  This is the code i am using :

          $input = $request->only('video' , 'url' , 'blob');
  
      $input['file'] =$request->file('blob');
  
  
  
      $ffmpeg = FFMpeg::create([
  
          'ffmpeg.binaries'  => 'C:/FFmpeg/bin/ffmpeg.exe',
  
          'ffprobe.binaries' => 'C:/FFmpeg/bin/ffprobe.exe'
  
      ]);
  
      $video = $ffmpeg->open($input['file']);
  
      $video
  
          ->filters()
  
          ->resize(new Dimension(320, 240))
  
          ->synchronize();
  
      $video
  
          ->frame(TimeCode::fromSeconds(10))
  
          ->save('frame.jpg');
  
      $video
  
          ->save(new Video\X264(), 'export-x264.mp4')
  
          ->save(new Video\WMV(), 'export-wmv.wmv')
  
          ->save(new Video\WebM(), 'export-webm.webm');

  This is the error :

  Unable to probe C :\Users\KAZMI\AppData\Local\Temp\php4155.tmp

  ffprobe failed to execute command "C :/FFmpeg/bin/ffprobe.exe" C :\Users\KAZMI\AppData\Local\Temp\php4155.tmp -show_streams -print_format json

  and this is the input data :

• Using ffmpeg to overlay black line or add border to two side by side videos

  14 février 2020, par user3135427

  I am using the following to generate a video that is side by side.

  ffmpeg -i left.mp4 -i right.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS, pad=iw*2:ih[bg]; [1:v]setpts=PTS-STARTPTS[fg]; [bg][fg]overlay=w" -y final.mp4

  It looks like this.

  http://www.mo-de.net/d/partnerAcrobatics.mp4

  I would like to place a vertical black line on top right in the middle or add a black border to the video on the left. If I add a border to the left video I would like to maintain the original sum dimension of the original videos. This solution would require subtracting the border width from the left videos width. I will take either solution.

  Thanks

• ffmpeg and uscreencapture not taking full screen

  27 mai 2022, par The Mr. Totardo

  I want to record my screen full screen with modest command below. My screen resolution is 1920x1080

  


  C :\Users\Totzfreelance\ffmpeg.exe -f dshow -i video="UScreenCapture":audio="Microphone (Realtek High Definition Audio)" -offset_x 0 -offset_y 0 -video_size 1920x1080 -pix_fmt yuv420p c :\Users\Totzfreelance\testing3.mp4

  


  but the video result dimension always 1280x720. There is part of screen not captured. I want it to be 1920x1080.
