[gst-devel] seeking changed in 0.3.2

[Joshua N Pritikin]

Here is my code to seek.  i added the _SET suffix to GST_SEEK_BYTEOFFSET to
get it to compile with 0.3.2.

static void
_fv_seek (FilmView *fv, gint64 offset)
{
  // g_warning ("seek %lld", offset);
  gst_pad_send_event (gst_element_get_pad (fv->cur_source->elem, "src"),
		      gst_event_new_seek (GST_SEEK_BYTEOFFSET_SET, offset, TRUE));
}

This stopped working with the upgrade from 0.3.1 to 0.3.2.  Now i get:

redael-filmview (pid:3503): GStreamer-ERROR **: file gstpad.c: line 1502 (gst_real_pad_dispose): assertion failed: (GST_PAD_PEER (pad) == NULL)

It looks like there is some new ref-counting code that isn't working yet
so i added a g_object_ref(pad) to see what happens next.  It looks like
filesrc gets stuck in g_tree_search.

Then a few seconds later:

#4  0x408c6f62 in gst_filesrc_get_type () from /usr/lib/gst/libgstelements.so

Any suggestions?

i noticed a brief comment in the release notes about events.  It would
really be nice if there was a migration guide.  i don't feel too bad
about API breakage if i know how to fix it.
