I don't know what "problems" mean in this context but if 
you plan to distribute FFmpeg (that means software based on 
FFmpeg source code), you have to conform to the GPL or the 
LGPL (depending on how you compiled FFmpeg).
If you want to use FFmpeg, you have to agree with the 
No-Warranty clause of the GPL (or the LGPL).

We do not know anything about patents (we have not used 
patents to implement FFmpeg), so we cannot answer this 
question but please see:

In case you neither use nor distribute software based 
on FFmpeg source code, then what you do does not concern 
the FFmpeg developers.
