Examples relate to an encoding apparatus, encoding device, encoding method, computer program and to a corresponding computer system. An encoding apparatus comprises processing circuitry configured to encode at least two video streams to perform video compression encoding using one or more encoders, wherein the one or more encoders are each configured to deter-mine an encoding context based on the video stream processed by the respective encoder, the encoding context comprising at least one or more reference frames determined by the respective encoder. The processing circuitry is configured to store at least one of the encoding contexts determined by the one or more encoders in a shared memory portion of the memory circuitry that is accessible to the one or more encoders. The processing circuitry is configured to proceed, using the one or more encoders, with encoding the at least two video streams based on an encoding context stored in the shared memory portion.
