First of all, don't try to play that file. This is full HD. You can
only get it working with *small* resolution videos, as there is no
rendering acceleration yet.

I get these too and it looks like a binary incompatibility problem
(although I have all my plugins from debian packages...). I am
investigating it...

You are missing h264parse from gst-plugins-bad.
