Probe multiple pads at once

[Fuentes]

Hello every one:

I got the following problem: When i try to probe a pad to unlink it and relink with a newly created fakesink all works fine if i only do in one pad. If instead i use a "for" loop to probe several element's to do the same thing, all fail at link the pads with  GST_PAD_LINK_REFUSED.

Here the piece of code that illustrates this:

for (int i = start; end <= i; --i)
{
        GstPad* source = gst_pad_get_peer(&_pads[i]);
        gst_pad_add_probe(
                source,
                GST_PAD_PROBE_TYPE_BLOCK_DOWNSTREAM,
                (GstPadProbeCallback)padBlockProbeFake,
                &_swap(i),
                NULL
        );
        g_object_unref(source);
}

Using only the code inside the for, all works fine. Using whit the for, all fails.

Anyone can help me?
Many thanks in advance.

There's nothing wrong in the code you pasted. Can you provide a full,
minimal/simplified testcase that reproduces your problem?
