Guillaume Desmottes 2ca3cf5cfa omxvideodec: add hack to pass color format from caps to OMX decoder 
This hack tries to pass as much information as possible from caps to the
decoder before it receives any buffer. These information can be used by
the OMX decoder to, for example, pre-allocate its internal buffers
before starting to decode and so reduce its initial latency.

This mechanism is currently supported by the zynqultrascaleplus decoder.
