how to capture with libvlcnet for .net
Posted: 04 Jul 2011 17:54
I just wonder how I could capture frames with the libvlcnet. I get an idea about how to do it. The VlcPlayerControl vlcpc have a methode that allows it:
vlcpc.DrawToBitmap(bmp , rbmp); // but I do not know how it works. or how I can visualize this bmp.
I also wonder if I could do it everything invisible. visible = false;
vlcpc.DrawToBitmap(bmp , rbmp); // but I do not know how it works. or how I can visualize this bmp.
Code: Select all
