For Online Computer Support, Ask a Computer Technician
Hi there Jace and welcome
It is quite easy now to do this, as there are services developed that make the process a lot easier.
you can use Livestream for this which you can see here
Once you have your domain setup (you could use GoDaddy.com) and your web page, you then just embedd the stream into your webpage so it looks like it is coming from your own webpage, and Live stream handles all the webca, delivery for you.
Is this what you are looking for?
