How to pass the filtered data which is returned from Custom Pipe to Child Component?

Parent Component

<app-search-bar (sender)="searchVideo($event)"></app-search-bar>

<ng-container *ngFor="let video of videos | search: query; let i=index;">
...
</ng-container>

<app-pagination (sender)="setStartEnd($event)"></app-pagination>

Custom Pipe

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'search'
})
export class SearchPipe implements PipeTransform {

  transform(value: any, args: any): any {
    if(!value){
      return null;
    }
    if(!args){
      return value;
    }
    args = args.toLowerCase();
    return value.filter((data: any) => {
      return JSON.stringify(data).toLowerCase().includes(args);
    })
  }

}

Child Component (app-pagination)

<div class="pagination" *ngIf="videos.length > 3">
...
</div>

I need to get the filtered data that returned by Custom Pipe so that with the help of that I can handle the number of pages in Pagination Component.
