How is your compile process on the host machine influenced by what you
install on your target?

Like with all the other external dependencies, it needs to be there at
compile time, and either statically linked or available on the target
at run time.

We had maintained, in your previous thread, that ffplay is not a
suitable tool for that, especially if you're not displaying at all.
Jsut decoding with "ffmpeg -i bla -f null -" should show you the
decoding performance, and whether it is realtime capable or not.
