Multi-process decoding method and multi-process decoding system
InactiveCN104850456AReduce image decodingReduce display effectResource allocationDecoding methodsRelevant information
The invention discloses a multi-process decoding method and a multi-process decoding system. The method includes starting a plurality of decoding processes; acquiring a plurality of decoding tasks; sequentially selecting a decoding task, acquiring load degree of each current decoding process according to related information, stored in a shared memory, of the decoding processes, and distributing the selected decoding task to the current decoding process with the lowest load for decoding. The problem that a single decoding process is easy to crash due to the fact that load balance cannot be achieved by multi-process decoding methods in the prior art is solved. The multi-process decoding method has the advantages that the decoding tasks are distributed to the decoding processes evenly to achieve load balance of the decoding processes, and accordingly, the risk of process crash caused by overload of a certain decoding process is reduced.
