I downloaded and got an error playing it back when it was trying to create the dsp node. This file "should" play back fine without any new stuff to install. I suspect we need an update for gst-dsp and the file should play ok then. I will ask the relevant people and get back to you.

I managed to play it with a custom GStreamer pipeline without using the dsp video decoder and it started playing but the cpu is not enough to decode 720p MPEG4 without help from the dsp.
