FFMpeg Dll Compilation

```
Hey Justin,

Can you please share what needs to be done with ffmpeg dlls to work with your 
code?

I quickly checked the avcodec-51.dll provided by you and it contains 3180 
functions whereas the latest avcodec-56.dll has only 211. What would account 
for such a big difference?

Thanks

```
