x264 license问题

How do you know if you need this license for a use of x264?  Here's a
short rundown, though it is not a substitute for legal advice:

1.  Is your application GPL?  If so, you don't need this license.
2.  Is your application server-side only and not distributed to
customers?  If so, you don't need this license.
3.  Is your application not GPL-compatible (e.g. proprietary),
distributed to customers, and links to x264?  If so, you do need this
license.
