I've been surveying for gst tracer for leak to adjust vaapi.
I think this tracer is very useful for gstreamer developers.
But, unfortunately, gst vaapi mini object is not inherited from
gst(mini)object.

But it would be great if we could use this infrastructure.
IMHO, There are 2 options

1. Replace gst(mini)object from current own vaapi object.
I think this is the best option. 
We can use not only gst tracer but also all things supported, eg. gir,
including future improvement!
But it'll be very tough time to code and verify.

2. Make vaapi tracer to trace vaapi object.
Actually, I've been doing this for a couple of days.
I prepared vaapi tracer but it's not perfect for several reasons.
 -  vaapi mini object doesn't have GType, which means i can't recognize by the
name of  leaked memory.
 ( I can recognize by only address)
 - Needs to modify gst-core lib (gsttracerutils) as far as I see.

I want to listen to other's opinion.:)
