 > I heard that vaapi adds a X dependency, while vdpau is header-only. (I
 didn't try to verify this.)
 I wonder if this is maybe only a compile-time dependency?
 At least it did not stop us from auto-detecting vaapi in 0.6, 0.7, 0.8,
 0.9, 0.10, 0.11, 1.0 and 1.1 and I can't reproduce a run-time dependency

 Otoh, it meant some effort to remove the dependencies on jack, alsa, sdl,
 zlib and bzlib (and jack even implies a stdc++ dependency).
