What's the output of

  gst-inspect-1.0 matroskamux | grep Version

?

Older versions of matroskamux required the framerate field to be present
on the input video caps, but this was removed some time ago.

You could try this:

   .... h264parse ! video/x-h264,framerate=25/1 ! matroskamux ! ..

or you could build this plugin:

https://github.com/thaytan/gst-rpicamsrc

which is a GStreamer source element that does more or less the same as
raspivid, but you can feed the output directly to h264parse+matroskamux.

Cheers
