Laravel Custom Validation - Validate video length

Laravel Custom Validation - Validate video length

Laravel provides a very powerfull set of validation rules ( but seems don't provide a method to validate a video file duration.

By the way Laravel has the Validator::extend() method to add some custom rules. You can check out the whole rule from the below link: Laravel Custom Validation rules.

So we need to create our custom rule.

First open your AppServiceProvider.php and the create a new custom rule called video_lenght in the boot function: 

public function boot()

/** others code here */

/** video duration validation 'video:25' */
Validator::extend('video_length', function($attribute, $value, $parameters, $validator) {

// validate the file extension
if(!empty($value->getClientOriginalExtension()) && ($value->getClientOriginalExtension() == 'mp4')){

$ffprobe = FFMpeg\FFProbe::create();
$duration = $ffprobe
->format($value->getRealPath()) // extracts file information
return(round($duration) > $parameters[0]) ?false:true;
return false;


Then in order to use  the new validation rule  put in your controller VideoController.php

public function store(Request $request)
$validator = Validator::make($request->all(), [
'video' => 'video_length:25', // 25 max video length in second

if ($validator->fails()) {
return redirect('video/create')

// Store the video post...

In order this code can works you need to has installed in your server 

FFmpeg and pbmedia/laravel-ffmpeg a package that provides an integration with FFmpeg for Laravel 5.6
