totem/gstreamer and h264/xvid formats

[Barbara Guida]

Is just me or totem+gstreamer is no more able to play h264 and xvid
video formats?

On the console messages are displayed:
** Message: Missing plugin: gstreamer|0.10|totem|H.264
decoder|decoder-video/x-h264, stream-format=(string)avc,
alignment=(string)au, level=(string)4.1, profile=(string)high,
parsed=(boolean)true (H.264 decoder)
or
** Message: Missing plugin: gstreamer|0.10|totem|XVID MPEG-4
decoder|decoder-video/x-xvid (XVID MPEG-4 decoder)

On the same files, the audio stream is played correctly and the video
are played as expected on mplayer or vlc.
