用于在JWPlayer的seek bar中使用的视频缩略图精灵的PHP库 JWPlayer

系统要求

PHP 7.x (请参阅 版本0.2 以获取支持PHP 5.5/5.6的最新版本)。

需要安装以下二进制文件

安装

composer require emgag/video-thumbnail-sprite

使用方法

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'] 

有两种不同的缩略图生成方法可用,ffmpeg (默认) 或 ffmpegthumbnailer

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

在将精灵组装成单个图像后保留单个源图像,而不是删除它

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