Mon programme (et à l'aide du fichier AviPreviewC.exe disponible sur le site
http://www.funkster.org) permet de créer un fichier qui reprend toutes les frames déjà téléchargé avec eMule ou eDonkey2000.
Explication :
Il crée une liste des fichiers .part et vérifie indique si ce sont des fichiers vidéo (avi), il permet ensuite de spécifier la résolution et la taille du fichier et créera ensuite le fichier de prévisualisation dans un répertoire donné et de le lancer par après;

Conclusion :
Je remercie Olivier Stephenson sans qui ce projet n'aurait jamais su être réalisable !
J'ai encore une mise à jour à faire : Faire une fenêtre de visualisation en temps réel de l'opération de AviPreviewC.exe (pas la console quoi)
Je mettrais à jour le code source dès que je l'aurais fait.
Si vous avez des suggestions, faites le moi savoir je verrais ce que je peux faire
