liste webcam

Le
gregb
Bonjour,

J'aimerais avoir la liste des webcam installer sur un pc.
J'ai les API pour me connecter et avoir une description de la webcam
connecter par defaut mais pas des autres
Exemple : sur mon poste j'ai 3 webcam usb connecter et j'aimerais avoir la
liste pour pouvoir changer de webcam toutes les 5 secondes par exemple
Si quelqu'un connait une APi la dessus ??

J'ai cette liste d'API WFM mais je trouve pas !! :-(


Merci d'avance

Greg

Bonjour,

J'aimerais avoir la liste des webcam installer sur un pc.
J'ai les API pour me connecter et avoir une description de la webcam
connecter par defaut mais pas des autres...
Exemple : sur mon poste j'ai 3 webcam usb connecter et j'aimerais
avoir la liste pour pouvoir changer de webcam toutes les 5 secondes
par exemple... Si quelqu'un connait une APi la dessus ??

J'ai cette liste d'API WFM mais je trouve pas !! :-(


Merci d'avance
