  • Video encoding
    Patent number: 11792398
    Abstract: A system can include a video processing engine to determine an estimated Quantization Parameter (QP) for a row of Coding Tree Units (CTUs) in a frame of a video. The processing engine can encode the row of CTUs in the frame of the video. A CTU in the row of CTUs can be encoded with a QP equal to the estimated QP. The system includes another video processing engine to determine an estimated QP for another row of CTUs of the frame of the video. The other processing engine can set a running QP to the estimated QP for the row of CTUs prior to the given video processor encoding a last CTU in the given row of CTUs. The other processing engine can further encode the other row of CTUs. CTUs encoded by the video processing engine and the other video processing engine can be stored in memory.
