请注意:这篇文章中会用到passthru,可能部分虚拟主机会将此命令禁用。
代码如下:
PHP
- <?php
- define('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
- $arr_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['start'] = $match[2]; //开始时间
- $data['bitrate'] = $match[3]; //码率(kb)
- }
- if (preg_match("/Video: (.*?), (.*?), (.*?)[,\s]/", $info, $match)) {
- $data['vcodec'] = $match[1]; //视频编码格式
- $data['vformat'] = $match[2]; //视频格式
- $data['resolution'] = $match[3]; //视频分辨率
- $arr_resolution = explode('x', $match[3]);
- $data['width'] = $arr_resolution[0];
- $data['height'] = $arr_resolution[1];
- }
- if (preg_match("/Audio: (\w*), (\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'] = $data['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);
- ?>
以上就是php 使用FFmpeg获取视频播放总时长与码率等信息示例代码的详细内容,更多请关注Gxl网其它相关文章!
