In fact, I had not realized that FFLIBS was used to link the shared
libraries and not only for the test programs.

I believe that would work, and having useless deps for tests programs is not
a problem. On the other hand, that would mean that a lavu test program can
not be run unless all the other libs have been built. Imagine someone
changing lavu/error.h and building error-test: they must wait for all lavc
and lavf to rebuild. Not very comfortable.
I see actually a simpler solution for the case at hand (the uncoded frame
test program): since this is not a really simple test
program, it can go into tools/ or tests/, and be build with:
PROGS += tools/uncoded_frame
That would have the additional advantage of allowing to use lavfi, that
would make it simpler and more powerful.
Would this be ok? Any preference between tools and tests?
Other test programs only test a very small part of the library and therefore
do not suffer from the problem.
