'.mp4'; break; case 'vimeo': $vimeo = new Vimeo('your_vimeo_client_id', 'your_vimeo_client_secret'); $videoInfo = $vimeo->getVideo($url); $videoUrl = $videoInfo['files'][0]['link']; $fileName = $videoInfo['name'] . '.mp4'; break; case 'facebook': $facebook = new Facebook([ 'app_id' => 'your_facebook_app_id', 'app_secret' => 'your_facebook_app_secret', ]); $videoInfo = $facebook->get($url); $videoUrl = $videoInfo->getSource(); $fileName = $videoInfo->getTitle() . '.mp4'; break; default: return 'Invalid platform';
