  • Patent number: 10291931
    Abstract: Techniques are provided for determining variance of a pixel block in a frame of video based on variance of pixel blocks in a reference frame of the video, instead of directly, for example, by calculating variance based on pixel values of the pixel block. The techniques include identifying a motion vector for a pixel block in a current frame, the motion vector pointing to a pixel block in a reference frame. The techniques also include determining the cost associated with the motion vector and comparing the cost to first and second thresholds. The techniques include determining the variance for the pixel block of the current frame based on the comparison of the cost to the first and second threshold and based on the variance of the pixel block of the reference frame.

    Abstract: Systems and methods for determining a target number of bits (target bitrate) for encoding a frame of video that will satisfy a buffer constraint in a parallel video encoder. The quantization parameter (QP) for a given encoding process may be determined for the frame based on the target bitrate to maintain a suitable average bitrate. In some embodiments, the bitrate used for one or more prior frame is estimated. In some embodiments, a buffer fullness update is made based on an estimated bitrate. In some embodiments, a bitrate to target for each frame is determined based on the frame type, estimated bitrate of a prior frame(s), and the updated buffer fullness.
