Bonjour,

Je dois afficher l'image d'une cam via une appli wpf. J'ai trouvé sur http://easywebcam.codeplex.com/ un exemple qui le fait et affiche très bien.

Quand je veux l'adapter à mon code celà ne fonctionne pas et lorsque je clique sur bouton start ou stop, cela m'engendre une erreur "System.NullReferenceException" Et je ne vois pas d'où cela peut venir. Je vois joins le code correspondant.
partie xaml :
Code : Sélectionner tout - Visualiser dans une fenêtre à part
