Thank you Martin.
This works perfectly.

I use GST_DEBUG( "The caps I want to output : %" GST_PTR_FORMAT, caps);

I got this from the documentation of gst_caps_to_string (http://www.gstreamer.net/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstCaps.html#gst-caps-to-string) that recommends using that.  It's shorter than having to free the memory allocated by gst_caps_to_string.

I read that GST_DEBUG_CAPS is deprecated - and it does not work.
Is there any other way for debugging CAPS?

I wrote some function for this purpose but what if have caps with other formats? It would be nice to have smth like GST_DEBUG_CAPS
.................................................................................................
void print_caps(Myfilter *filter)
{
 int width=0,height=0;
    guint32 fourcc;
    if (GST_IS_CAPS(GST_PAD_CAPS(filter->sinkpad_video)))
    {
    GstStructure *sinkcaps = gst_caps_get_structure (GST_PAD_CAPS(filter->sinkpad_video), 0);
    gst_structure_get_int (sinkcaps, "width", &width);
    gst_structure_get_int (sinkcaps, "height", &height);
    gst_structure_get_fourcc (sinkcaps, "format", &fourcc);
           switch (fourcc) {
           case GST_MAKE_FOURCC ('I', '4', '2', '0'): GST_INFO("SINK CAPS: width %d, height: %d format: I420\n",width,height);
