VLC i see, i know VLC, its great, however, the film needs to be sent by e-mail or so to family, relatives etc. and just some of em still don't know VLC, let alone how to get VLC to mirror films...
so it has to be done while capturing and i know its possible for i did it before a year or so before
Unless you are trying to send it live I was thinking that you could do the processing in VLC after capturing and re-save to a new file then send that.
SharpCap itself doesn't have a mirror function, so the function must be coming from the camera driver, which means that you are unlikely to see different results by changing SharpCap versions I'm afraid.
