Hey all! So I really want to try my hand at making a program that implements a webcam. At first, I would just like to make a program that displays the current image from the webcam every, say, one second. The catch: I really would like to know if I can do this without downloading jmf, or fmj, or anything, for that matter. I am looking for someway to do it with the packages already available without downloads. Many thanks to you all for the great, quick, responses you always give!
A low level solution is to write native code that interacts with the webcam directly. I think a higher level solution is to query the operating system (again, natively) for video capturing devices through a driver and get a feed from there. I don't have experience with either method, but I would recommend looking into the latter option, unless you can find an even higher level solution (like a third party library that works for all kinds of operating systems).
You shouldn't try to reinvent the wheel. Embrace "additional APIs".
