You can film in public but if anyone doesn’t want to appear in the recording they can ask to be removed or even go to the authorities. And even if they do not request it and show up in a public display, they can open a case with the authorities.
You can always ask but you can’t demand it. Taking photos of even a single individual without their consent in a public place is perfectly legal in most of Europe. What is not okay is publishing that image though even that isn’t automatically illegal. If you’re not the focus of the shot but you appear in the background in the crowd then that is okay to publish even if you say no.
