H.264 encoding is disabled unless you --enable-gpl --enable-libx264. But don't you think H.264 encoding is quite an important feature for a video framework? So anyway, the point is that we want to be consistent wrt external libraries. If you want to have DASH enabled by default, make sure to have a native XML parser, or discuss the policy about detecting all the external libraries within the configure. -- Clément B.
