Thanks for your reply.
My video data is form 2 image sensor, and is line interleaved, so I need to
deinterleave it first.

The  gstdmabuf.html
only explains allocate and check, don't know the difference between 

Seems that I need to implement it myself?

I searched the current gst-plugin-good, only v4l2 uses
gst_dmabuf_allocator_new ();
sys/v4l2/gstv4l2bufferpool.c:517:      pool->allocator =
gst_dmabuf_allocator_new ();
I'll further check how it work.

Any suggestions would be greatly appreciated.
