• I'm having problem encoding video using Laravel FFMPEG to save it to Minio storage

  8 juillet 2022, par Ibrahim Ahmad

  I am trying to convert video from .mp4 extension into HLS format (.m3u8) using Laravel FFMPEG.

  


  FFMpeg::fromDisk('minio')
          ->open($videoFile)
          ->exportForHLS()
          ->onProgress(function ($percentage) use ($movie) {
               Cache::put('progress-' . $movie->id, $percentage);

               if($percentage >= 100) {
                 Cache::forget('progress-' . $movie->id);
                }
             })
             ->toDisk('minio')
             ->addFormat($lowBitrate, function (HLSVideoFilters $filter) {
                 $filter->resize(480, 360);
             })
             ->addFormat($midBitrate, function (HLSVideoFilters $filter) {
                 $filter->resize(852, 480);
              })
              ->addFormat($highBitrate, function (HLSVideoFilters $filter) {
                  $filter->resize(1920, 1080);
              })
              ->save($newFile);


  


  I have a .mp4 video stored in Minio S3 storage, want to export to Minio S3 storage again. And I came up with this error

  


  RecursiveDirectoryIterator::__construct(C:\Windows\Temp/52325dd01cfde90a\): Access is deni (code: 5)


  


  What does the error message say ? But when I export the video file to local, it works totally fine. How do I solve this problem. Thanks.

  


  Update :
The export process requires windows temporary folder, and I cleared the temporary folder, the problem is solved for now. This probably the temporary folder can't hold many files.

  


• FFMpeg crop a portrait (vertical) video square 1:1

  1er avril 2022, par hugger

  SOLVED... It was a UI issue... Not an FFpeg issue.

  


  I am new to FFMpeg. I am stuck on cropping a portrait video taken from a portrait device square.

  


  I would like my video output to be 1080x1080.

  


  First, I tried this.

  


  FFmpegKit.execute(`-y -i ${media.path} -vf "crop=1080:1080:exact=1" ${path}`)


  


  As I hoped, this worked for photos. (but strangely rotates the photo) - looking into that...

  


  BUT, for videos it does not work. instead it turns the video landscape.

  


  I then tried to add scale :

  


  FFmpegKit.execute(`-y -i ${media.path} -vf "crop=1080:1080:exact=1, scale=1080:1080" ${path}`)


  


  But this left me with the same result.

  


  Here are the console logs for some more information :

  This is the result, when i replace
-i {media} with
-f lavfi -i smptebars=r=60000/1001:s=1080x1920:d=1

  


  

  


  ALMOST but not 1:1...

  


  I have not had any luck online trying to find a solution for this so I have decided to post on here.

  


  I hope I can get some guidance here !

  


  Cheers.

  


• avfilter/vf_subtitles : pass storage size to libass

  avfilter/vf_subtitles : pass storage size to libass
  Due to a quirk of the ASS format some tags depend on the exact storage
  
  resolution of the video, so tell libass via ass_set_storage_size.
