Php calls ffmpeg to obtain video information. phpffmpeg

Ffmpeg is an open-source computer program that can be used to record, convert, and convert digital audio and video into streams. It contains libavcodec to ensure high value portability and CODEC quality.

This article describes how to use php to call ffmpeg to obtain video information. To call ffmpeg, you must first install ffmpeg on the server. The installation method is simple and you can search for it by yourself.

The Code is as follows:

<? Php // defines the ffmpeg path and command constant define ('ffmpeg _ cmd', '/usr/local/bin/FFMPEG-I "% s" 2> & 1 '); /*** use ffmpeg to obtain video information * @ param String $ file video file * @ return Array */function getVideoInfo ($ file) {ob_start (); passthru (sprintf (FFMPEG_CMD, $ file); $ video_info = ob_get_contents (); ob_end_clean (); // use the output buffer to get all output content of ffmpeg $ ret = array (); // Duration: 00:33:42. 64, start: 0.000000, bitrate: 152 kb/s if (preg_match ("/Duratio N :(.*?), Start :(.*?), Bitrate: (\ d *) kb \/s/", $ video_info, $ matches) {$ ret ['duration'] = $ matches [1]; // video length $ duration = explode (':', $ matches [1]); $ ret ['seconds'] = $ duration [0] * 3600 + $ duration [1] * 60 + $ duration [2]; // convert to seconds $ ret ['start'] = $ matches [2]; // start time $ ret ['bitrate'] = $ matches [3]; // bitrate unit: kb} // Stream #0: 1: Video: rv20 (RV20/0x30325652), yuv420p, 352x288,117 kb/s, 15 fps, 15 tbr, 1 k tbn, 1 k t Bc if (preg_match ("/Video :(.*?), (.*?), (.*?) [, \ S]/", $ video_info, $ matches) {$ ret ['vcodec'] = $ matches [1]; // encoding format $ ret ['vformat'] = $ matches [2]; // video format $ ret ['resolution'] = $ matches [3]; // resolution list ($ width, $ height) = explode ('x', $ matches [3]); $ ret ['width'] = $ width; $ ret ['height'] = $ height;} // Stream #0: 0: Audio: cook (cook/0x6B6F6F63), 22050Hz, stereo, fltp, 32 kb/s if (preg_match ("/Audio :(. *), (\ d *) Hz/", $ video_info, $ matches )){ $ Ret ['acodec'] = $ matches [1]; // Audio Encoding $ ret ['asamplerate'] = $ matches [2]; // audio sampling frequency} if (isset ($ ret ['seconds']) & isset ($ ret ['start']) {$ ret ['play _ time'] = $ ret ['seconds'] + $ ret ['start']; // actual playback time} $ ret ['SIZE'] = filesize ($ file); // video file size $ video_info = iconv ('gbk', 'utf8 ', $ video_info); return array ($ ret, $ video_info);} // output video information $ video_info = getVideoInfo ('myvideo. avi'); print_r ($ video_info [0]) ;?>

Output:

Array( [duration] => 00:33:42.64 [seconds] => 2022.64 [start] => 0.000000 [bitrate] => 152 [vcodec] => rv20 (RV20 / 0x30325652) [vformat] => yuv420p [resolution] => 352x288 [width] => 352 [height] => 288 [acodec] => cook (cook / 0x6B6F6F63) [asamplerate] => 22050 [play_time] => 2022.64 [size] => 38630744)
