Member Function Documentation

◆ create() [1/2]

static Glib::RefPtr<Gst::MessageCustom> Gst::MessageCustom::create ( MessageType  type,
const Glib::RefPtr< Gst::Object >&  src,
Gst::Structure structure 
)
static

Create a new custom-typed message.

This can be used for anything not handled by other message-specific functions to pass a message to the app. The structure field can be nullptr.

Parameters
typeThe Gst::MessageType to distinguish messages.
srcThe object originating the message.
structureThe structure for the message. The message will take ownership of the structure.
Returns
The new message.

MT safe.

◆ create() [2/2]

static Glib::RefPtr<Gst::MessageCustom> Gst::MessageCustom::create ( MessageType  type,
const Glib::RefPtr< Gst::Object >&  src 
)
static

A create() convenience overload.
