Common understanding is that it's OK to use Apache-licensed components in
LGPL, see e.g. https://community.jboss.org/thread/149779?_sscc=t
Note that ffmpeg does not include libstagefright.so, libmedia.so, and their
ilk. The AOSP libraries are only used to instruct the linker to set some
references, and even these are not technically necessary (VLC chose a
different approach, I don't think it's any "cleaner").
