Currently we're trying to create a project which has access via web cam to capture the Video and Audio and store it on Cache as WMV.
We have been able to successfully capture the Video into the "Isolated Storage" or "Raw" File format. The next step is to create a silverlight friendly format like WMV version 8 or 9 which can be used for Replay.
Asof now we have been able to successfully get a project from Link - http://mtaulty.com/CommunityServer/blogs/mike_taultys_blog/archive/2009/12/10/silverlight-4-more-on-capturing-video-from-webcams.aspx
to capture the video and encode it into AVI format for replay mode. Unfortunately we've not been able to get a client version code snippet or API that allows encoding into WMV format directly.
Any pointers in the direction would be most appreciated.
