IP cameras

[chmario]

I am working with IP cameras I was wondering which one is the best plug-in for this task.
Currently  I am using uridecodebin but I can not access the width and height capabilities. Knowing explicitly the dimension of the image is very important for my application.

Does any one knows how to work with IP cameras?

I am using:
GstCaps *videoCaps = gst_pad_get_caps(pad);
GstStructure *str = gst_caps_get_structure (videoCaps, i);
gst_structure_get_int (str, "width", &width);

But seams that there is no width property of the type int.

So I use  gst_structure_n_fields (str),  gst_structure_nth_field_name(str, j) to inspect the fields, I found:
field0: width type: GstIntRange
field1: height type: GstIntRange
field2: framerate type: GstFractionRange
field3: format type: GstFourcc

There is a width and hight but of the type GstIntRange, so seams that is not set to a specific value.

Try using "gst_pad_get_negotiated_caps", that will give the current negotiated caps in the pad.
