The output port of the encoder is encoded data. GstBufferPool is meant
for fixed sized buffers. This is not a good fit.

BufferPool is a good fit for the input port, since the data is raw and
fixed size. It is also the type of data that cost a lot of CPU to copy
as it's much larger.

Implementing a buffer pool around fixed set of buffers may introduce
certain difficulties. One thing you need to make sure is to never send
twice the same pool instance in propose_allocation() method.

good luck,
Nicolas
