Some options after disable-libffmpeg_static seems to say they are enabled, but when i look at the configure scripts, it seems they will only be enabled if libffmpeg_static is enabled.
Is my assumption correct? and can this be somehow grouped and hidden (or auto disabled) if libffmpeg_static is disabled?

PS, I guess the static switches are made default as this is currently the way it is shipped pre-compiled? Would be nice if next time such switches are made optional to prevent build failures.
