Spice-based video coding method and system extension of h264

The present invention provides a new SPICE-based video codec H264 extension method, comprising the steps of: providing an additional supplemental bag support system required for operation; SPICE protocol to provide the client the ability to spread the decoder H264; H264 providing server protocol SPICE encoder extended capability; SPICE protocol server and providing SPICE H264 protocol client capability negotiation; SPICE providing server protocol H264 and MJPEG encoding selection algorithm and an upper dynamic configuration interfaces. The present invention significantly reduces the SPICE protocol video playback scene network bandwidth, provide a richer video codec and protocol processing strategy SPICE guarantee compatibility, and provide good SPICE protocol H264 video codec configuration or interface, and It does not require the secondary development of software within the virtual machine.
