is it necessary to compile fffmpeg?

[songshizhao]

Hello, there's a little question. I found that you provided a compiled version of lib download, so is it necessary to follow [Compile and Use FFmpeg Libraries for Windows Runtime (Windows 10 or Windows 8.1 Apps)]? Can i just use the compiled dll? I don't know much about ffmpeg and i am not good at C ,thank you for your help :D
