While there is nothing wrong with reinventing a wheel, writing your own video streaming application is a REALLY big wheel.

While NetMeeting (or the Linux NetMeeting app -- yes I know, you want Windows) may be an unwieldy monster, a lot of time went into making that unwieldy monster. Even if you only have to do 1/10th of that work, it's still a ton of work.

Have fun, you may make something really popular...but it will take some effort. I would look a little harder at other video conference apps, possibly, and maybe you can find one that works for you.

I will say that UDP is probably a bad choice. What you want is a TCP/IP system that has some sort of quality-of-service feature (possibly using UDP for timing? who knows), as UDP has a small packet size and (worst of all) ordering is not guaranteed. For important packets, especially ones that set up states for your program, you can't have them being lost either. Consider the size of what you are biting off, and see if it wouldn't be worth your time to just buy a 1 GHz machine for $200 at Walmart.

that is switch to HTTP transfer and try to transform the application into an Internet Explorer plugin

This is a probably a very bad idea for video streaming. Not the plugin part, but the HTTP part.

Also, with the MSIE plugin...there probably aren't a ton of MSIE plugins written in Perl. How much pain are you looking for? As I've said, consider the size of what you are biting off. Simply upgrading the computer or trying something like CUSeeMee may be a better option!

I am not trying to discourage you, this would be a fantastic project to work on -- just saying, I don't think it's going to just fall into place and be better than the commercial/open-source apps already in existance. Most of those folks new what they were doing -- the slow down you see *is* because of your processor, not the app. Whatever you get will still be slowed down by the processor, and Perl may be (unfortunately) slower than the stuff they are using.
