php ffmpeg获取视频缩略图

1.环境

centos 7ffmpeg version 2.8.15 Copyright

2.centos7安装ffmpeg

centos7安装ffmpeg

sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.rosudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpmsudo yum install ffmpeg ffmpeg-devel -y

【Ubuntu安装ffmpeg】

sudo add-apt-repository ppa:kirillshkrogalev/ffmpeg-nextsudo apt-get updatesudo apt-get install ffmpeg

查看环境变量是否配置成功

ffmpeg -version

3.项目安装ffmpeg包

composer require php-ffmpeg/php-ffmpeg

github链接https://github.com/PHP-FFMpeg/PHP-FFMpeg

4.php代码

<?phpinclude '../vendor/autoload.php';use FFMpegFFMpeg;class MyFfmpeg{    public function run()    {        $file_path = __DIR__ . '/' . uniqid() . '.jpg';        $ffmpeg = FFMpeg::create([            'ffmpeg.binaries' => '/usr/bin/ffmpeg',            'ffprobe.binaries' => '/usr/bin/ffprobe'        ]);        $video = $ffmpeg->open('1.mp4');        $video->frame(FFMpegCoordinateTimeCode::fromSeconds(1))->save($file_path);    }}$a = new MyFfmpeg();$a->run();

附Fmpeg读取视频信息

<?phpdefine('FFMPEG_PATH', '/usr/local/ffmpeg2/bin/ffmpeg -i "%s" 2>&1');  function getVideoInfo($file) {     $command = sprintf(FFMPEG_PATH, $file);     ob_start();  passthru($command);  $info = ob_get_contents();  ob_end_clean();    $data = array();  if (preg_match("/Duration: (.*?), start: (.*?), bitrate: (d*) kb/s/", $info, $match)) {    $data['duration'] = $match[1]; //播放时间    $arwww.easck.comr_duration = explode(':', $match[1]);    $data['seconds'] = $arr_duration[0] * 3600 + $arr_duration[1] * 60 + $arr_duration[2]; //转换播放时间为秒数    $data*), (d*) Hz/", $info, $match)) {    $data['acodec'] = $match[1]; //音频编码    $data['asamplerate'] = $match[2]; //音频采样频率  }  if (isset($data['seconds']) && isset($data['start'])) {    $data['play_time'] = $www.easck.comdata['seconds'] + $data['start']; //实际播放时间  }  $data['size'] = filesize($file); //文件大小  return $data;}  //用法$video_info = getVideoInfo('video.mp4');print_r($video_info);?>
