video-thumbnail-sprite

WARNING: This library is no longer maintained /WARNING

PHP library for generating video thumbnail sprites to be used for thumbnails in JWPlayer's seek bar.

System requirements

PHP 7.x (see release 0.2 for the latest version supporting PHP 5.5/5.6).

Following binaries need to be installed

Either ffmpeg (tested with >= v2.2) or ffmpegthumbnailer
imagemagick (tested with >= v6.6)

Installation

composer require emgag/video-thumbnail-sprite

Usage

use Emgag\Video\ThumbnailSprite\ThumbnailSprite;

$sprite = new ThumbnailSprite();
$ret = $sprite->setSource('path-to-source-video.mp4')
       ->setOutputDirectory('dir-to-store-sprite-and-vtt')
       // filename prefix for image sprite and WebVTT file (defaults to "sprite", resulting in "sprite.jpg" and "sprite.vtt")
       ->setPrefix('sprite') 
       // absolute URL of sprite image or relative to where the WebVTT file is stored
       ->setUrlPrefix('http://example.org/sprites')
       // sampling rate in seconds 
       ->setRate(10) 
       // minimum number of images (will modify sampling rate accordingly if it would result in fewer images than this)
       ->setMinThumbs(20)
       // width of a single thumbnail in px 
       ->setWidth(120) 
       ->generate();
       
// $ret = ['vttFile' => 'path-to-vtt-file', 'sprite' => 'path-to-sprite-file']

There are two different thumbnailing methods available, ffmpeg (default) or ffmpegthumbnailer.

// default, is set implicitly if not provided
$sprite->setThumbnailer(new Thumbnailer\Ffmpeg());
// change thumbnailer to ffmpegthumbnailer
$sprite->setThumbnailer(new Thumbnailer\FfmpegThumbnailer());

To keep individual source images of the sprite instead of removing it after assembling the sprite into a single image:

$sprite->setOutputImageDirectory('dir-to-store-images');
