No, it isn't. You made the claim, burden of proof is on you. Go ahead and dig up a law about it somewhere in the civilized world.
Rules in the state of Lower Saxony, Germany.
Video surveillance of "publicly accessible locations" is only permitted in order to protect people or objects located therein and only if protecting the rights of the recorded people is not more important. Furthermore any such locations must have visible measures declaring that the area is under surveillance. Any material collected that way that is not necessary for the purpose of protection (anymore) is to be destroyed afterwards. If a person is identified through video surveillance they are to be notified (unless it's for anti-crime purposes).
The federal level law is similar except it includes "for specified authorized purposes" and the definition for that wasn't at hand. Just uploading stuff to the web for laughs most likely isn't an authorized purpose. Since the federal laws are likely made to conform to a EU law you can likely find similar laws in all EU member states but I'm not digging through all those laws just to find you additional proof.
That was the first result I could find on Google. I also found a note that recording demonstrations is a violation of the basic right to gather.
