Télécharger des flux vidéo en ASP.NET

Je dois faire une interface de télécharger de gros des vidéos jusqu'à 30 mo puis de le transmettre et de le convertir en format FLV, et puis jouer dans un navigateur... c'est requise sur mon site dans la rubrique "Galerie Vidéo" module.
Mon application web en C# et ASP.NET. Je peux aussi utiliser jQuery.

Je dois envoyer le fichier vidéo en morceaux puis de les fusionner au niveau du serveur, diffuser, créer la miniature de la vidéo et puis le lire.

Merci de me donner la solution si quelqu'un a de.

Je l'ai trouvé un peu de code, mais c'est tout en PHP. Je n'ai pas trouvé de C#, ASP.NET code.

Enfin j'ai reçu le code pour télécharger le fichier vidéo en morceaux... mais s'il vous plaît m'aider à faire d'autres processus, comme la création de ses vignettes et affichage de la vidéo dans un navigateur.

Voici le code pour télécharger la vidéo en plusieurs segments.
