output of “gst-feedback-0.10”

VLC and mplayer agree that this is a video file: <http://dx.doi.org/10.1371/journal.pone.0072805.s001>. However, GStreamer cannot find a suitable decoder for the “video/x-gst-fourcc-mp2v“ video stream.

ffplay fails to decode the video properly as well and just draws noise, the output suggesting a corrupted file:
