how to derive an instance from GstBuffer (0.11.x)

[Kaijun Tang]

Hi,

 

Since gstreamer-0.11.0, GstBuffer seems non-derivable due to Miniobject being defined as GType rathern than GTypeInstance. How do I design an instantiable object or class derived from GstBuffer?

 

Kind Regards

Kai

Hi,

  Sub-classing buffers is gone in 0.11/1.0. You are meant to use GstMeta
instead (either re-using an existing one or creating your own).

You might also want to implement a custom memory allocator to work
with hardware buffers.
