<pre>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);</pre>
