Abstract
An apparatus for encoding and decoding video receives a request to decode a current video frame. The apparatus determines whether encoding is within a threshold for a previous video frame. Additionally, the apparatus waits for the encoding to start if the encoding is within the threshold. Further, the apparatus provides a signal to begin encoding the current video frame. Also, the apparatus submits a decode workload to a graphics processor unit (GPU) for the current video frame. The apparatus additionally submits, in parallel with submitting the decode workload to the GPU, an encode workload to the GPU for the previous video frame.
