It is not even clear what these emms_c() are supposed to achieve: create_filtergraph() (where it may be called) does not call ASM functions itself; it merely sets some function pointers. Furthermore, there are no colorspacedsp functions using MMX (checked by checkasm which does not use declare_new_emms()). Finally, checking whether to issue emms_c() is overblown anyway.
