"License" is a legal requirement- and laws vary from state to state, country to country. In some places you must have a license to possess a gun, some places a license to carry a gun, etc. Without knowing WHERE you are (we get questions from dozens of nations) and WHAT kind of license you mean, it is impossible for us to give you a meaningful answer. Sorry.
You need to define the term gun license. In most of the US there is no license to own a gun. Some states require a license to carry a gun. others to carry a gun concealed. There is also a license to make or sell guns. All are different and have different procedures.
This all depends on the country and location where you live.
It depends on several factors; Where you are located and exactly what you mean by "gun license." Do you mean a license to carry a gun? A license to purchase a gun? A license to build guns?

You never need a license to have an Airsoft gun.
Sure. As long as the person doing the shooting of the gun has a license. The person doing the filming doesn't need a license as long as they don't shoot the gun at all.
