Hi Thomas,

take a look at gst-plugins-base/sys/xvimage for an example. What you
need to do now is to is basically:
- Provide a buffer pool in GstBaseSrc::propose_allocation
- Implement this GstBufferPool (you could e.g. use GstVideoBufferPool as
  a base class)
- Most probably implement a custom GstMemory and corresponding
  GstAllocator, which is then used by your buffer pool to allocate the
  memory of the buffers.
