[gst-devel] How to add a complicate property to an element

[Hu, Gang A]

Hi,
I want to add a property to a camera source element. This property contains five field. How can create this property with one property id and extract it?
For example, to add the ae_windows property to the v4l2src, the user can use the command
gst-launch v4l2src ae_windows="width=49, height=60, centerx=20, centery=30, weight=3" ! xvimagesink.
to specify the ae_windows.
Thanks.
