Hi Kamil,
after a discussion on IRC, we concluded that s5p-mfc have this bug that
disallow multiple reqbufs calls before streaming. This has the impact
that it forces to call REQBUFS(0) before setting the new number of
buffers during re-negotiation, and is against the spec too.
As an example, in reqbufs_output() REQBUFS is only allowed in QUEUE_FREE
state, and setting buffers exits this state. We think that the call to
<http://lxr.free-electrons.com/ident?i=reqbufs_output>s5p_mfc_open_mfc_inst()
should be post-poned until STREAMON is called.

cheers,
