Changing the license headers in the source files is not the same as
changing the actual license text. If the code is under LGPL then
anything which qualifies as "under LGPL" should be OK. 

One licensing issue is that GPL-licensed files are distributed with
FFmpeg but there seems to be no copy of the GPL included. COPYING only
contains LGPL 2.1 and I didn't find the full GPL text in any other file
either.
