FFmpeg error Unable to load FFMpeg during parallel encoding
1er janvier 2021, par DrJohnI'd like to build web service on the Laravel platform which allows users upload some videos on a server. During uploading video files I use ffmpeg to encode them and compress.
I can't install ffmpeg on my hosting and so I have downloaded packages and executable files from https://ffmpeg.org/download.html and locate them on my web directory. Then I make all steps to install ffmpeg in my Laravel project.
I try to upload a video file and it's OK. The time to upload and encode is about 20 seconds. During encoding of the first video file I try to upload the second. And the second video file falls with the error "Unable to load FFMpeg". But the first video file is encoded successfully. When the first encoding is completed and I repeat uploading the second file it encoded successfully as well.
So I think that ffmpeg can work only with only one file at the time and I can't build multi-user service.
Please help me to find solution.


Here is a peace of code which use to encode files :


try {
 $pub_path = Storage::disk('public')->getAdapter()->getPathPrefix();
 $videopath =$pub_path . $myusertheme->public_reference.'/'.$this->random_filename(25,'','mp4');
 //echo (Storage::disk('public')->getAdapter()->getPathPrefix().'<br />');
 echo ($videopath);
 $ffmpeg = \FFMpeg\FFMpeg::create([
 'ffmpeg.binaries' => "./usr/bin/ffmpeg",
 'ffprobe.binaries' => "./usr/bin/ffprobe",
 'timeout' => 3600, // The timeout for the underlying process
 'ffmpeg.threads' => 12, // The number of threads that FFMpeg should use
 'set_command_and_error_output_on_exception' => true,
 ]);
 $vid=$ffmpeg->open($request->file('videofile')->getRealPath());
 $vid->save(new \FFMpeg\Format\Video\X264('libmp3lame', 'libx264'), $videopath);

/*
 $videopath = $myusertheme->public_reference.'/'.$this->random_filename(25,'','mp4');
 //FFMpeg::fromDisk('local_root')
 $ffmpeg
 ->open($request->file('videofile')->getRealPath())
 ->export()
 ->onProgress(function ($percentage) {
 //echo ($percentage.'/n');
 if ($percentage===100)
 {

 $videopath = $this->random_filename(25,'','mp4');
 }})
 ->inFormat(new \FFMpeg\Format\Video\X264('libmp3lame', 'libx264'))
 ->toDisk('public')
 ->save($videopath);

*/

 } catch (EncodingException $exception) {
 $videopath = null;
 $command = $exception->getCommand();
 $errorLog = $exception->getErrorOutput();
 echo $errorLog;
 return \Response::json('Ошибка кодировки файла', 500);

 }
