PHP如何获取视频总时长与码率等信息
作者:互联网
利用PHP中的FFmpeg读取视频播放时长与码率等信息
function

$file
) {
define(
'FFMPEG_PATH'

'/usr/local/ffmpeg2/bin/ffmpeg -i "%s" 2>&1'

= sprintf(FFMPEG_PATH,
$file

ob_start();
passthru
(
$command

= 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
[

//码率(kb)

$video_info
