expression régulière preg_match_all

Version imprimable

bonjour,
je recup la sortie du programme ffmpeg et j'aimerais récupérer la valeur de SAR et DAR

j'arrive à trouver le nbr de pixels largeur hauteur par cette fonction

Code:

1
2
3
4
 
$pattern = '/Video: .*, ([0-9]{2,4}x[0-9]{2,4})/';
	preg_match_all($pattern, $result, $matches, PREG_PATTERN_ORDER);
	$resolution = $matches[1][0];

j'ai essayé cela mais je ne recupère pas la valeur entre les crochets [ et ] (je récup celle qui est plus loin et qui ne m'intéresse pas ;p)
c'est celle ci qui m'interesse : [SAR 16:15 DAR 4:3],

Code:

1
2
3
4
5
6
7
 
 
 
  $pattern = '/SAR ([0-9]{1,3}:[0-9]{2})/';
 
preg_match_all($pattern, $result,$out, PREG_PATTERN_ORDER);
print_r($out);

voici la sortie

Code:
