VideoReader support GStreamer 0.10. So if you have installed Gstreamer 1.0, it will not work.

Once you install Gstreamer, you probably have to install the suitable plugins (codecs) to read the video. Try playing the video using Totem Player. I believe this uses Gstreamer.

Do not try VLC. It uses ffmpeg libraries and not gstreamer.
