1. A computer-implemented method of video coding comprising:
determining a relationship function relating latency and bitstream size associated with transmitted encoded video data based on one or more feedback pairs of the latency and the bitstream size, the relationship function having a slope parameter and an intercept parameter;
determining one or more outliers of the relationship function;
determining an updated relationship function relating the latency and the bitstream size by updating the intercept parameter based on the one or more outliers;
looking up a target bitstream size that corresponds to a predetermined latency value using the updated relationship function;
providing the target bitstream size to an output filter to determine a version of the target bitstream size, the output filter having a parameter which is determined using reinforcement learning; and
providing the version of the target bitstream size to be used to set at least one encoder setting to encode a video frame.
