Here's how I do it. I make a file with the output of ffmpeg and then
just parse the file for duration. After looking at a lot of options,
this proved to be the easiest and most reliable. Here's my code that
also finds the mid-time and grabs an image of the middle frame for a
thumbnail:
//tmpname is the temp name of the video
//First we get some info about the video with ffmpeg
$cmd="/usr/local/bin/ffmpeg -i $tmpname 2> $tmpname.info";
system($cmd,$ok);
if (!$ok) {
return false;
}
$ffinfo=file_get_contents($tmpname.".info");
$ffinfo=substr($ffinfo,strpos($ffinfo,"Duration:")+10,strlen($ffinfo));
//Now that we got the duration we parse the string so that we get hours,
mins and seconds
$ffinfo=substr($ffinfo,0,strpos($ffinfo,"."));
$runningtimeparts=explode(":",$ffinfo);
foreach($runningtimeparts as $rt) {
$newparts[]=floor((($rt/60)*0.5)*60);
}
//Get the mid point
$midtime=($newparts[0]*3600)+($newparts[1]*60)+$newparts[2];
$midtimestr=implode(":",$newparts);
//$jpegname is the name of where you want to save the thumbnail
$cmd="/usr/local/bin/ffmpeg -i $tmpname -ss $midtimestr -y -r 1 -vframes
1 -f mjpeg $jpegname";
system($cmd);
