C#, VB.NET Skype Videoo Call Recording

Need coder, C# or VB.NET and Directshow filters experience Dll for capturing audio and video from Skype needed. There is a program implementing this functional (_[login to view URL]) without using Skype API . Skype API doesn't provide interface for working with video. On the first step I want a brief analysis what technique should be used: - to get the information of the Skype video and audio streams starting(hooks and directshow filter used) - how to capture these streams (DirectShow filters I presume, how to insert them in the skype graph, using of merits etc) - how to record those streams, which free codecs to use (lame mp3, ffdshow, any other) I think that playing with the above program could help a lot. The next part is to create dlls implementing this functional, details of interface will be given based on the above anlisys. Payment in two parts, 1- after report, 2 - after dll ready Please post your offers with price for step 1 and 2 and time constraint
