Video from firefox OS phone plays back sideways

Question

If I take a video using a firefox OS phone (Geeksphone Peek running stable 1.1), and download it to a computer, it plays back sideways (vlc). It doesn't play back sideways from the actual gallery though.

The strange thing is, if I try to open that same video from a url with the mozactivity API:

var activity = new MozActivity({
  name: "view",
  data: {
    type: [
      "video/webm",
      "video/mp4",
      "video/3gpp",
      "video/youtube"
    ],
    url: "https://foo.bar/video.3gpp"
  }

});

To stream it through the gallery, it WILL play back sideways. Is this a known bug anywhere or could someone explain to me why this could happen?

This is not FirefoxOS-specific, iOS videos are also displayed sideways in vlc for me. I think this is a known problem with both vlc and gstreamer-based video players, like totem. See here for a bug report on Ubuntu's video player with references to gstreamer's upstream bug report:
