Totally unrelated may be, I have a one plus 7 pro with the front camera that pop's up, when I opened the link it just popped up and went down. This is the first time that is happening. Weird.
Right, So I am doing a research project and If I want to use this library in that project, does that mean I have to pay to use it. My project is currently closed source , because don't want anyone to steal stuff before I publish my paper. After that the code goes public.
