Current VPE driver does not start the job until all the buffers for a transaction are queued. When running in multiple context, this might increase the processing latency. Alternate solution would be to try to continue the same context as long as buffers for the transaction are ready; else switch the context. This may increase number of context switches but it reduces latency significantly. In this approach, the job_ready always succeeds as long as there are buffers on the CAPTURE and OUTPUT stream. Processing may start immediately as the first 2 iterations don't need extra source buffers. Shift all the source buffers after each iteration and remove the oldest buffer. Also, with this removes the constraint of pre buffering 3 buffers before call to STREAMON in case of de-interlacing.
