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

[Hu, Gang A]

Stefan.
Thanks for your suggestion. I would like to keep the property list small.
As composited property is not common in GStreamer, adding 5 property for the
Windows settings maybe a good choice right now.
Thanks.

While you could define your own gparamspec type, i would sugest you to simply
add 4 properties instead. Please use a descriptive name so that people won't
have to guess what "ae" stands for.
