Get length of a video using regex and ffmpeg

Question

From the following ffmpeg -i output, how would I get the length (00:35)--

$ ffmpeg -i 1video.mp4

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from \'/Users/d         


        

Answer 1

for latest version :

$cmd = "avconv -i input.mp4 2>&1 | grep Duration | awk '{print $2}' | tr -d ,";
$output = exec($cmd);
echo "\n\n==OUTPUT===|".$output."|=====\n\n";

Now $output will hold your duration of video input.mp4

format will be: hh:mm:ss.ms

e.g 00:02:17.25
