--- Comment #11 from Michael Catanzaro <mcatanzaro at igalia.com> ---
Example code from Sebastian, for a non-terrible solution to this (I'm posting it here so that I don't lose it):

GList *decoder_factories, *h264_decoders;
GstCaps *caps;

decoder_factories = gst_element_factory_list_get_elements (GST_ELEMENT_FACTORY_TYPE_DECODER |
        GST_ELEMENT_FACTORY_TYPE_MEDIA_VIDEO,
        GST_RANK_MARGINAL);

// Repeat this for all caps you care about

caps = gst_caps_new_empty_simple ("video/x-h264");
h264_decoders = gst_element_factory_list_filter (decoder_factories, caps, GST_PAD_SINK, FALSE);
gst_caps_unref (caps);

if (h264_decoders != NULL) {
  // found h264 decoder
}

gst_plugin_feature_list_free (h264_decoders);

// end repeat

gst_plugin_feature_list_free (decoder_factories);
