I have a question about JW player license.
I'm sorry to hear you speak English.
I am using JW Player 7.4.3 free version now.
Use services are open market formats operated by universities.
In this case, we ask if you need to purchase a one-year license.
We will also ask you how to apply the license if you purchase it.
Currently, jwplayer.key = (keyvalue) is used in this way.
