don't see way to set default caps for properties
I hope I'm not missing something, but I don't see a way to set default caps for properties. Something like:
subclass::Property("caps", |name| {
glib::ParamSpec::caps(
name,
"Caps",
"Desired caps to passthru on src pad",
gst::Caps::static_type(),
DEFAULT_CAPS,
glib::ParamFlags::READWRITE,
)
})
