Method and apparatus for real time parallel encoding

摘要

There are provided apparatus and methods for parallelizing an encoding process across multiple processors. An apparatus includes a computing resource balancer and a splitter. The computing resource balancer is for assigning encoder instances to respective ones of the multiple processors based on at least one of thread affinity and process affinity. The splitter is for temporally dividing an incoming video sequence into discrete GOPs such that each of the encoder instances is capable of encoding the incoming video sequence in parallel so that each of the discrete GOPs is encoded on a respective one of the multiple processors.

1. An apparatus for parallelizing a video encoding process across multiple computer hardware processors, comprising:
a resource balancer for assigning encoder instances to respective ones of the multiple computer hardware processors based on process affinity; a splitter for temporally dividing an incoming video sequence into discrete group of pictures (GOPs) such that each of the encoder instances encodes the incoming video sequence in parallel so that each of the discrete GOPs is encoded on a respective one of the multiple hardware computer processors; and a multiplexer that re-orders pictures in the discrete GOPs into sequence order after GOP encoding is finished, wherein said multiplexer reorders the pictures using at least one of timestamps and sequence numbers for at least one of a picture level and a GOP level.
