[Bug 774223] opencv: move base opencv filter class and utilities to gst-libs

[GStreamer (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=774223

--- Comment #14 from Philippe Renon <philippe_renon at yahoo.fr> ---
About the API exposing opencv types:

Only IplImage* is exposed.

There are two IplImage pointers that are aliases of GstBuffer data.

Relevant code in the implementation looks like this:

  if (!gst_buffer_map (inbuf, &in_info, GST_MAP_READ))
    goto inbuf_map_failed;
  transform->cvImage->imageData = (char *) in_info.data;

Where transform->cvImage is a IplImage*.

Is it possible to hide the two IplImage pointers behind some gst abstraction ?
GstBuffer* ? ;)
