test videoscale methods

[Alejandro Vázquez]

I found a solution for the problem i use "jpegparse" before jpegdec and works!

I am not sure how to detect if it is scaling.

I try the next where I declared pipe elements i do the next:

GstElement *videoScale = gst_element_factory_make("videoscale", "videoScale");
GstPad *padVideoScale = gst_element_get_pad(videoScale,"padVideoScale");
g_signal_connect(padVideoScale, "notify::caps",
G_CALLBACK(video_caps_notify), NULL);

and the callback (video_caps_notify) do:
static void video_caps_notify(GObject* obj, GParamSpec* pspec, gpointer data)
{
	const GstCaps *caps;
    GstStructure *str;
    gint width,height;
    gdouble rate;
    caps = gst_pad_get_negotiated_caps((GstPad*)obj);
    g_print("video_caps_notify\n");
    if (caps)
    {
    	str=gst_caps_get_structure(caps,0);
    	gst_structure_get_int(str,"width",&width);
    	gst_structure_get_int(str,"height",&height);
    	g_print("!!: GStreamer negotiated %dx%d \n", width, height);

    }
}

I'm not sure if it is well it correctly but never reaches the callback


Thanks!
Regards!
