Add more parameters to function with declared parameter

Question

I want to add two variable in addFilter() function. But the problem is that this method allows only one parameter to get. How to extend it?

FMpeg::fromDisk('public')
        ->open('/uploads/videos/' .$video->file_name)
        ->addFilter(function($filters) {
            $filters->clip(FFMpeg\Coordinate\TimeCode::fromSeconds($start), FFMpeg\Coordinate\TimeCode::fromSeconds($duration));
        })
        ->export()
        ->toDisk('public')

definition of code: I can't change this

public function addFilter(FilterInterface $filter)
    {
        $this->filters->add($filter);

        return $this;
    }

Just add it... explain what exactly you want to add and what do you want to do with them (with the variables) — lewis4u

@lewis4u when I try to add my app says that function requires 1 parameter 3 given — Programmmereg

But which function has 3 parameters...here in your code there is a function with 1 and 2 parameters, but none with 3 — lewis4u

I have function addFilter() with 1 parameter. I want to pass to this function $start and $duration, because that variables aren't visible in this function — Programmmereg

You may want to use use with the function to pass those variables to the Clousure

FMpeg::fromDisk('public')
        ->open('/uploads/videos/' .$video->file_name)
        ->addFilter(function($filters) use($start, $duration) {
            $filters->clip(FFMpeg\Coordinate\TimeCode::fromSeconds($start), FFMpeg\Coordinate\TimeCode::fromSeconds($duration));
        })
        ->export()
        ->toDisk('public')
