Description Carlos Rafael Giani 2013-01-14 00:25:58 UTC 
According to http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gsttag.html#GstTagImageType , the image type is stored as part of the caps structure. This is wrong though. Taken from tags.c:

  if (image_type != GST_TAG_IMAGE_TYPE_NONE) {
    GST_LOG ("Setting image type: %d", image_type);
    image_info = gst_structure_new ("GstTagImageInfo",
        "image-type", GST_TYPE_TAG_IMAGE_TYPE, image_type, NULL);
  }
  sample = gst_sample_new (image, caps, NULL, image_info);

so, the actual way to find out the image type is to use gst_sample_get_info().

    The image type is not in the info structure in the sample,
    not in the caps.
