High-yield multi-threading method and apparatus for video encoders/transcoders/decoders with dynamic video reordering and multi-level video coding dependency management
Disclosed is an exemplary video coder and video coding method according to an embodiment of the present invention. The exemplary video coder includes a scheduler, a plurality of processors and a multiplexer. The scheduler can examine processing units in an input buffer to determine an order for the processing unit to be coded by a processor. If the processing unit under examination depends on a processing unit not yet processed, the processing unit under examination can be merged with other processing units, if any, that share a similar dependency. If the processing unit under examination does not depend on any processing units not yet processed, it can be sent to a next available processor for coding. When a processing unit is sent to a processor, any merged processing units that depend on sent processing unit can also be sent to a next available processor.
