Look again at rule #2.  If you are using the checklist, use the whole checklist.  The purpose of rule #2 is to make it easy for your end-user to replace the ffmpeg DLLs with ones they compile themself, and use your application with the substitutes.  If you make a new DLL with your own object files mixed with the ffmpeg object files, they won't be able to substitute.

There are other ways to meet the requirements of the LGPL, but they are more complicated, and the checklist won't help you.  You might even need a real lawyer.  I am not.

HTH,
