[Testcase] Recurrent Network, Input Stream

In order to test recurrent neural networks,
we need to implement #738 (we surely need new synchronization
policy from tensor_mux/merge)

As the first step of #738, I, hereby, provide
the 4x4 BGRx video/x-raw steam with frame-sequence
identification marks.
