H.264 is a popular codec used for encoding the videos that are hosted on the video server and delivered over the internet. Achieving real time encoding still remains a challenging problem. A possible solution to minimize the encoding time would be to develop applications with high level of Thread-Level Parallelism (TLP) to exploit the power of multi-core processors. Parallelization strategies at various levels such as Macro-block level, slice level, frame level have been proposed by various authors. Most of these techniques suffer from the drawbacks of limited scalability, and data dependency. The authors propose in this paper, a high level parallelization method based on Group-Of-Pictures (GOP).
