README

本模块为 PHP_FFmpeg 库提供了一个简单的封装，将库作为 ZendFramework 服务暴露。

安装

设置

1. 将此项目添加到您的 composer.json 文件中

   "require": {
       "buonaparte/bnp-ffmpeg-module": "dev-master"
   }

2. 现在运行以下命令，让 composer 下载 BnpFFMpegModule

   $ php composer.phar update

安装后

在您的 application.config.php 文件中启用它。

<?php
return array(
    'modules' => array(
        // ...
        'BnpFFMpegModule',
    ),
    // ...
);

配置

通过复制并调整 config/module.config.php.dist 到您的配置包含路径来配置模块

$ffmpegConfig = array(
  'configuration' => array(
      'ffmpeg.threads'   => 4,
      'ffmpeg.timeout'   => 300,
      'ffmpeg.binaries'  => '/opt/local/ffmpeg/bin/ffmpeg',
  ),
  /**
   * Custom logger service, must resolve to a Psr\Logger\LoggerInterface instance pulled from the ServiceManager
   */
  'logger' => 'ffmpeg_logger',
  /**
   * Custom FFProbe service, pulled from the ServiceManager
   */
  'ffprobe' => 'ffprobe_service'
);

return array(
  /**
   * Root Module configuration
   */
  'bnp-ffmpeg-module' => array(
      /**
       * For single ffmpeg service instance you can just uncomment the bellow line
       */
//        'ffmpeg' => $ffmpegConfig,
      /**
       * For multiple ffmpeg services with different configuration you will specify them in an array,
       * from to the service name to service configuration
       */
//        'ffmpeg' => array(
//            'FFMpeg1' => array_merge_recursive($ffmpegConfig, array()),
//            'FFMpeg2' => array_merge_recursive($ffmpegConfig, array()),
//        ),
      /**
       * FFProbe configuration
       */
      'ffprobe' => array(
          'configuration' => array(
              'ffprobe.timeout'  => 30,
              'ffprobe.binaries' => '/opt/local/ffmpeg/bin/ffprobe',
          ),
          /**
           * Custom logger service must resolve to a Psr\Logger\LoggerInterface instance pulled from the ServiceManager
           */
          'logger' => 'ffprobe_logger',
          /**
           * Custom cache service must resolve to a Doctrine\Common\Cache\Cache instance pulled from the ServiceManager
           */
          'cache' => 'ffprobe_cache'
      )
  ),

  /**
   * Service Manager config
   */
  'service_manager' => array(
//        'factories' => array(
//            /**
//             * FFProbe service factory
//             */
//            'FFProbe' => 'BnpFFMpegModule\Factory\FFProbeServiceFactory',
//            /**
//             * For single ffmpeg service instance you can just register the factory for the service name
//             */
//            'FFMpeg' => 'BnpFFMpegModule\Factory\FFMpegServiceFactory'
//        ),
//        'abstract_factories' => array(
//            /**
//             * For multiple ffmpeg service instances you must register the FFMpeg abstract factory
//             */
//            'BnpFFMpegModule\Factory\FFMpegAbstractServiceFactory'
//        )
  )
);

使用方法

$ffmpeg = $serviceLocator->get('FFMpeg');

// Open video
$video = $ffmpeg->open('/your/source/folder/input.avi');

// Resize to 720x480
$video
    ->filters()
    ->resize(new Dimension(720, 480), ResizeFilter::RESIZEMODE_INSET)
    ->synchronize();

// Start transcoding and save video
$video->save(new X264(), '/your/target/folder/video.mp4');
