Abstract: An example of a server includes a processor and a computer-readable storage medium configured to store instructions that, when executed by the processor, cause the server to perform operations. The operations comprise encoding segments of a video stream at a variable bitrate while the variable bitrate is assigned a first value. The variable bitrate is assigned a second value in response to a load on the processor exceeding a threshold load. The segments of the video stream are encoded at the variable bitrate while the variable bitrate is assigned the second value. The assigning the variable bitrate the second value can include applying a bitrate-decrease function to the first value. Assigning the variable bitrate the second value reduces the load on the processor.
