example, FFmpeg read video playback time length and bit rate
The code is as follows:
| The code is as follows |
Copy Code |
| <?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]; Play time
$arr _duration = Explode (': ', $match [1]);
$data [' seconds '] = $arr _duration[0] * 3600 + $arr _duration[1] * + $arr _duration[2]; Convert playback time to seconds
$data [' start '] = $match [2]; Start time
$data [' bitrate '] = $match [3]; Bit Rate (KB)
}
if (Preg_match ("/video: (. *?), (. *?), (. *?) [, \s]/", $info, $match)) {
$data [' vcodec '] = $match [1]; Video encoding format
$data [' vformat '] = $match [2]; Video format
$data [' resolution '] = $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 coding
$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
$video _info = getvideoinfo (' Video.mp4 ');
Print_r ($video _info);

In this case, PassThru is used, and some virtual masters may be able to disable this command
Example 2
| The code is as follows |
Copy Code |
| Get thumbnails of video files
function Getvideocover ($file, $time, $name) {
if (empty ($time)) $time = ' 1 ';//default intercept first second frame
$strlenstrlen = strlen ($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 320x240". $name. "", $out, $status);
$str = "Ffmpeg-i". $file. "-y-f mjpeg-ss 3-t". $time. "-S 320x240". $name;
echo $str. "
";
$result = System ($STR);
}
Gets 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 of//cuplayer.com
$ctime = Date ("y-m-d h:i:s", Filectime ($file));//Creation time
$duration = Explode (":", $time);
$duration _in_seconds = $duration [0]*3600 + $duration [1]*60+ round ($duration [2]);//cuplayer.com converted to seconds
Return Array (' Vtime ' => $vtime,
' CTime ' => $ctime
);
