How can you negotiate a buffer-pool with out knowing the o/p video-format
(format  from decoder output).?

What i did in my branch is : hard-coded the video-format to NV12 (which is the
only format suppring by sandybride-intel) and negotiated the pool. But this is
not the right way. This format will be different for different drivers. 

We need to decode the first buffer and then check what format has been
providing by the driver.
