Need Information on setting up Hardware Memory Buffers

[Stirling Westrup]

I've never before had to delve into the depths on how gstreamer allocates
and passes video buffers along, but its looking like I will soon need to
know this.

I am assisting in porting OpenCL to gstreamer 1.0, and we'll need some
method of allocating and passing around OpenCL buffers. Ideally, for my
purposes, we'll want to build a pipeline that passes a single unchanging
buffer pointer, but attaches different metadata to describe
transformations. When someone needs an actual frame of data, we'll combine
the transformations and  perform them with an OpenCL kernel that writes to
a standard memory buffer.

The documentation on how memory allocation and passing works in gstreamer
is kinda scant though, and I was hoping folks could point me to useful
tutorials and/or example code that I can learn from.
