Gstreamer on SLAM Dunk


We unboxed the SLAM Dunk, and tried to run some existing code on it. While many things are working, gstreamer is not. We have been using gstreamer to playback video files (like mp4, mpeg, and m2ts files). Gstreamer (and apps based on gstreamer, like the ubuntu Videos app) does not play back any video files on the SLAM dunk, but they all work on a fresh Jetson TK1. Does the SLAM Dunk intentionally change the way that gstreamer works? Is there a work-around? What is the preferred way to record and playback video files on the SLAM Dunk?
