Is there way that I can tell if someone is recording video conversations?

I should avoid these calls at all cost. I've seen videos of girls being unaware they're recorded on YouTube. That's sad!

@LostInTheDesert: That is not only sad, it is wrong and illegal. If you cannot trust that friend then maybe he is not a real friend. I wait for the day when such publising of videos without the consent of all shown constitutes a crime and is sentenced severely.

I briefly read an article that you in fact CAN, but need some apps or software.
Why are you concerned about being recorded?

Maybe it's a phobia, with technology etc, I wouldn't want anything with my face on it to be seen publicly or ridicule.

I can understand that.
Be more careful who your trust.

Thanks, I'm doubting every video call now unless it's my immediate families.
