Back to the topic, Larry. It seems that the video ads are appearing again.
I've been playing with the settings, but it seems the ads keep showing up ... not sure what the deal is with that.
In any case, the simple explanation of how the webcam icon works (images pulled from your site/provider) is that a private area of this site is capable of capturing the stream on demand.
There is also a background C++ Win32 Service that requests and captures an image from that stream occasionally (configurable settings -- basically, wait a while, play the stream and wait a while until grabbing a capture, then go back and repeat).
The captured image is processed through a C++ imaging library I wrote, which samples it down through bilinear interpolation, sharpens it through a 3x3 convolution filter (might be 5x5 but not sure without looking at the latest code) then does all the fancy discrete cosine transform stuff to compress and save it to disk as a standard JPEG file.
But the damn ads keep appearing, seemingly no matter how I configure the delay before capture. I haven't had time to investigate further, but the site actually feeding it out is probably doing something clever to prevent what I'm attempting to prevent.
Not much I can do until I get more time to spend on the effort.
