Following php func might help u:

private static function checkForScanType($ffmpegBin, $srcFileName,
$frames=1000)
{
/*
[Parsed_idet_0 @ 0000000000331de0] Single frame detection: TFF:1 BFF:96
Progressive:2 Undetermined:1
[Parsed_idet_0 @ 0000000000331de0] Multi frame detection: TFF:0 BFF:100
Progressive:0 Undetermined:0
*/
if(stristr(PHP_OS,'win')) $nullDev = "NULL";
else $nullDev = "/dev/null";

$cmdLine = "$ffmpegBin -filter:v idet -frames:v $frames -an -f rawvideo -y
$nullDev -i $srcFileName -nostats  2>&1";
$lastLine=exec($cmdLine , $outputArr, $rv);
if($rv!=0) {
return 0;
}
$tff=0; $bff=0; $progessive=0; $undermined=0;
foreach($outputArr as $line){
if(strstr($line, "Parsed_idet")==false)
continue;
$str = strstr($line, "TFF");
sscanf($str,"TFF:%d BFF:%d Progressive:%d Undetermined:%d", $t, $b, $p, $u);
$tff+=$t; $bff+=$b; $progessive+=$p; $undermined+=$u;
}
$scanType = 0; // Default would be 'progressive'
if($progessive<$tff+$bff)
$scanType = 1;
return $scanType;
}
