• 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.

• How to solve the problem of low performance of complex video generation using ffmpeg ?

  21 novembre 2019, par Zedd

  I use ffmpeg to generate a complex video.

  This video consists of the following materials :

  1. Original video

  2. Video dub

  3. Background music

  4. Subtitle

  My code logic is as follows

  1. Combine ’Original video’ and ’Video dub’ into ’Video A’

  2. Subtitle ’Video A’ as ’Video B’

  3. Add ’Background music’ for ’Video B’ as ’Video C’

  The ’Video C’ is the video I want.

  My Code

  // Step1:
  
  ffmpeg -i VideoDub.mp3 -i OriginalVideo.mp4 VideoA.mp4
  
  // Step2:
  
  ffmpeg -i VideoA.mp4 -vf subtitles=Subtitle.srt -y VideoB.mp4
  
  // Step3:
  
  ffmpeg -i VideoB.mp4 -i BackgroundMusic.mp3 -filter_complex "[1:a]aloop=loop=-1:size=2e+09[out];[out][0:a]amix" -ss 0 -t 100 -y VideoC.mp4

  Design defect

  • I think my code is very redundant
  • poor performance
  • There are many times of encoding
  • It takes too long to generate such a video
  • The CPU usage has reached 100%.

  My Question

  How to solve the above problem？
