PHP uses the FFmpeg interface to get video playback duration, bitrate, thumbnails, and creation time

FFmpeg is a video plug-in, we can use the call FFmpeg interface to obtain information about the video, including video playback length, video bitrate, video thumbnail and video creation time, this article introduces how PHP uses FFmpeg interface to obtain video information, You need a friend to refer to.

FFmpeg get thumbnail images of video files:

function Getvideocover ($file, $time, $name) {   if (empty ($time)) $time = ' 1 ';//default intercept first Second first frame   $strlen = strlen ($file) ;   $videoCover = substr ($file, 0, $strlen-4);   $videoCoverName = $videoCover. '. JPG ';//thumbnail name//exec ("Ffmpeg-i". $file. "-y-f mjpeg-ss". $time. "-T 0.001-s". $name. ", $out, $status);   $str = "Ffmpeg-i". $file. "-y-f mjpeg-ss 3-t". $time. "-S". $name;   echo $str. " </br> ";   $result = System ($STR);   }

Fmpeg read video playback duration and bitrate

<?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] ; Playback time $arr _duration = explode (': ', $match [1]); $data [' seconds '] = $arr _duration[0] * 3600 + $arr _duration[1] * + $ar R_DURATION[2]; Convert playback time to seconds $data [' start '] = $match [2]; Start time $data [' bitrate '] = $match [3]; Bitrate (KB)} if (Preg_match ("/video:"), (. *?), (. *?), (. *?) [, \s]/", $info, $match)) {$data [' vcodec '] = $match [1];//video encoding format $data [' vformat '] = $match [2];//video Format $data [' Reso Lution '] = $match [3];    Video resolution $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];//audio encoding $data [' asamplerate '] = $match [2];//audio sampling frequency} if (Isset ($data [' seconds ' ]) && isset ($data [' Start ']) {$data [' play_time '] = $data [' seconds '] + $data [' start '];//actual playback time} $data [' Size '] = filesize ($file);  File size return $data;} Usage $video_info = getvideoinfo (' video.mp4 ');p rint_r ($video _info);? >

Fmpeg get the total length and creation time of the video file

function GetTime ($file) {   $vtime = exec ("Ffmpeg-i". $file. " 2>&1 | grep ' Duration ' | Cut-d '-F 4 | sed s/,//");//Total length   $ctime = Date (" y-m-d h:i:s ", Filectime ($file));//creation time   //$duration = Explode (": ", $time);   $duration _in_seconds = $duration [0]*3600 + $duration [1]*60+ round ($duration [2]);//Convert to Seconds   return array (' vtime ' = > $vtime,   ' ctime ' = $ctime   );}
