But there's no abstraction for selecting "something from a number of
streams" in GStreamer. That's my point.

Me neither. I just used "tracks" because they were already there. You
may subsitute GST_FORMAT_TRACKS by GST_FORMAT_STREAMS. I like that
better, anyway.

Please note that it is a tardec, not a tardemux. If it were a tardemux,
I'd just create as many pads as there are streams. But the streams can
only be accessed one by one, like on a CD or in the tuner element.

Because the interface is already there:

q = gst_query_new_duration (GST_FORMAT_STREAMS);
gst_element_query (e, q);
gst_query_parse_duration (q, NULL, &d);
g_message ("Number of available streams: %i", (int) d);

q = gst_query_new_position (GST_FORMAT_STREAMS);
gst_element_query (e, q);
gst_query_parse_position (q, NULL, &d);
g_message ("Current stream: %i", (int) d);

g_message ("Skipping to next stream...");
gst_element_seek (e, 1., GST_FORMAT_STREAMS, GST_SEEK_FLAG_NONE,
      GST_SEEK_TYPE_SET, d + 1, GST_SEEK_TYPE_NONE, 0));

A new custom tag?
