• 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.

  


• Problem with streamcopy of a part of av1 video in ffmpeg

  22 avril 2020, par vorrom

  I'm trying to cut part of a video from av1-mp4 file with FFMmpeg command and I want do it withuout recompressing. But there is no result.
I try method with -ss -t or -to parameters with different combinations.

  



  ffmpeg -ss 10 -i D:\in_av1.mp4 -t 5 -vcodec copy -acodec copy D:\out_av1.mp4


  



  -ss from input file get me 15 seconds video from beginning instead 5 seconds from 10

  



  ffmpeg -i D:\in_av1.mp4 -ss 10 -t 5 -vcodec copy -acodec copy D:\out_av1.mp4


  



  this way get 5 seconds audio file without video data.
It seems to me that coder can not find start point for operation.

  



  I make an av1.mp4 example file, you can find it here. https://pixeldrain.com/u/c8fbQgYK I understand that AV1 is new format and have experimental flag while converting with it. But nevertheless FFmpeg carrectly change result when I change -t parameter. If I use

  



  ffmpeg -ss 10 -i D:\in_av1.mp4 -t 7 -vcodec copy -acodec copy D:\out_av1.mp4


  



  it give me 17 seconds. So -t part working. Whats why I hope there is way to solve my problem.

  



  I use ffmpeg-20200417-889ad93-win64-static for Windows.
