Yes.  They are tested so that do what they are supposed to do.  Some
have SIMD and/or threading to make them quicker (I don't think eq does
though).  Many support more than just yuv420p (might not be valuable to
you right now but does save you from having to write code for every
different pixel format you want to support).

Also, please don't top post.
