In the following example, the serial stream processes the results faster than my parallel stream. Can anyone explain this behaviour please?

They studied slice-level, function-level and stream-level parallelism. Jacobs et al. [43] have ana- lyzed MB-level parallelism for MPEG-2 and MPEG-4. In the specific case of H.264 there has been previous works in the parallelization at GOP, frame, slice, func- tion and MB levels. ...
