php使用ffmpeg视频分析

php使用ffmpeg的扩展不再支持php高版本升级,这里使用 passthru 函数来执行视频分析

安装

composer require tinymeng/ffmpeg-php 1.0.0  -vvv

类库使用的命名空间为 \tinymeng\ffmpeg

获取视频信息

use \tinymeng\ffmpeg\FFMpeg;

$url = 'http://video-oss.959.cn/video/2018-12-27/8hYHmx4BZ7zE5kSa.mp4';
//或
$url = '/data/wwwroot/123.mp4';

$ffmpeg = FFMpeg::create();
$ffmpeg = $ffmpeg->open($url);
$info = $ffmpeg->getVideoInfo();

var_dump($info);

获取的视频信息如下
