Or do jou mean my device isn’t representative?
Yes, this. Most devices it just works, and a small minority will work with a little effort. A miniscule number will be like yours. It isn’t representative of the average experience. It’s an outlier.
Out of curiosity, how long ago was this? It very well may have the support now, though if it’s from some manufacturer using proprietary drivers for their webcams, for some crazy stupid reason, then maybe not.
I’m willing to bet I could teach someone how to count in binary on their fingers who doesn’t know binary in five minutes or less. They don’t need to know it’s binary. It’s just a simple rule that you add one and if that finger is up it instead goes down and the next goes up. They don’t need to know more than that. Then they just work backwards to get the final count. Knowing this is binary can be helpful, but it isn’t a prerequisite.
