• FFMPEG for thumbnail from video distorted when downloaded

  17 juillet 2020, par bjacobs

  I am grabbing a thumbnail image from an mp4.

  


  When I use -c:v mjpeg, the thumbnail appears fine in the browser, but is completely distorted when I preview it on my Mac. If I use -c:v jpeg2000 the image looks fine on my Mac, but it does not show in the browser.

  


  Full command :

  


  ffmpeg -ss 3 -i https://some_site/some_video.mp4 -vf thumbnail,scale=480:480 -q:v 2 -frames:v 1 -f image2 -c:v jpeg2000 -r 1 -vframes 1 tmp/my_thumbnail.jpg

  


  -vs-

  


  ffmpeg -ss 3 -i https://some_site/some_video.mp4 -vf thumbnail,scale=480:480 -q:v 2 -frames:v 1 -f image2 -c:v mjpeg -r 1 -vframes 1 tmp/my_thumbnail.jpg

  


  What encoding do I need to use in order for the generated thumbnail to both be viewable in the browser and also preview-able on Mac ?

  


  This is what the distorted image looks like :


  


  I'm beginning to think this is an macOS issue, but even if it is, I'd like to know if FFMPEG would have a solution for it so that even users with the buggy OS can properly preview the image.

  


  Output :

• Getting "Your FFProbe version is too old..." error in Laravel during file upload with FFMpeg

  9 septembre 2020, par pjotr79

  currently I'm working on a video uploader (to S3) script in Laravel. I'd like to get some info about the uploaded video and later I'd like to create thumbnails as well (with the help of this plugin). As a first step I've installed the FFMpeg with brew :

  


  $ brew update
$ brew upgrade
$ brew cleanup
$ brew install ffmpeg --force
$ brew link ffmpeg


  


  Then in composer

  


  $ composer require php-ffmpeg/php-ffmpeg


  


  When I'm checking the installation I get the following

  


  which ffmpeg
/usr/local/bin/ffmpeg

which ffprobe
/usr/local/bin/ffprobe


  


  By checking the version :

  


  ffmpeg -version

  The path also seems to be ok

  


  echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin


  


  But when I'm trying to upload a video file (sample.mp4) I have the following error message :
Your FFProbe version is too old and does not support -help option, please upgrade.

  


  Here's the snippet from my code to test the upload :

  


      use FFMpeg;


    public function upload(Request $request)
    {
        if ($request->hasFile('files')) {
            $files = $request->file('files');
            foreach ($files as $key => $file) {
                $filename = pathinfo($file->getClientOriginalName(), PATHINFO_FILENAME);
                $extension = $file->getClientOriginalExtension();
                $filename = str_slug($filename).'.'.$extension;
                Storage::disk('s3Files')->put($filename, file_get_contents($file),'public');
                $fileurl = \Config::get('s3.files').$filename;

                $ffprobe = FFMpeg\FFProbe::create([
                    'ffmpeg.binaries'  => '/usr/local/bin/ffmpeg',
                    'ffprobe.binaries' => '/usr/local/bin/ffprobe'
                ]);

                $filesave = new File();
                $filesave->name = $filename;
                $filesave->type = $file->getClientMimeType();
                $filesave->size = $file->getSize();
                $filesave->duration = $ffprobe->format($fileurl)->get('duration');
                $filesave->save();

            }
        }
    }


  


  Now I spent hours to try to find a solution (also checking this thread here, but I couldn't solve the issue.

  


  My dev environment runs on Mac OS X 10.15.5, with Nginx and PHP 7.4.

  


  Do you have any idea how could I fix this problem ?
