Totem does not find proper codec package to install

I'm trying to play a mp4 video with h264 codec, and totem try to search the codec packages but it does not work, take a look at the picture. It should be more friendly to users (it used to work in the past).

So, if you install manually xubuntu-restricted-extras, it plays the video.
