Wavefront parallelism is effective for parallel video encoding thanks to its merits of low latency, no quality loss and high degree of parallelism. In traditional video encoders, macroblock row wavefront (MRW) parallelism was widely adopted. However the performance of MRW is limited by workload unbalance and computing resource unbalance among multiple work threads. This paper proposes a new dynamic...
MB-level parallelism is widely used in parallel video coding thanks to its merits of low latency, no performance loss and high degree of parallelism. Most of video encoders with MB-level parallelism employ MB Row Scheduling (MRS) scheme. In software video encoder, early terminate algorithms tend to cause significant difference in coding time of different MBs. Consequently, the running speeds of multiple...
