This may be possible.

This does not make any difference at all.

Please read (and understand) the LGPL to get all information you need about the
obligations when distributing binaries of LGPL'd software.
Among them are:
Do not use GPL-code (it does not like closed-source projects)
Inform your users that your software uses code from FFmpeg
Show the LGPL to your users
Do not claim that FFmpeg belongs to you - we have had enough of that;-)
Share the exact source code (including some build instructions) of FFmpeg that
you used. This has to be done in a way that allows your users to replace the
binary of FFmpeg that comes with your software with a self-compiled version (for
example by changing code in the FFmpeg sources that you provide).

libdca != FFmpeg
