    Abstract: In an example, a method of decoding video data may include receiving (800) a palette mode encoded block of video data of a picture. The method may include receiving (802) encoded palette mode information for the palette mode encoded block of video data. The encoded palette mode information may include a plurality of instances of a first syntax element and a plurality of syntax elements that are different from the first syntax element. The method may include decoding (804), using bypass mode, the plurality of instances of the first syntax element before decoding the plurality of syntax elements that are different from the first syntax element using context mode. The method may include decoding (806), using context mode, the plurality of syntax elements that are different from the first syntax element after decoding the plurality of instances of the first syntax element using bypass mode.

    Abstract: An example device for coding video data includes a memory configured to store video data; and one or more processing units implemented in circuitry and configured to: store motion information for a first coding tree unit (CTU) line of a picture in a first history motion vector predictor (MVP) buffer of the memory; reset a second history MVP buffer of the memory; and after resetting the second history MVP buffer, store motion information for a second CTU line of the picture in the second history MVP buffer, the second CTU line being different than the first CTU line. Separate threads of a video coding process executed by the one or more processors may process respective CTU lines, in some examples.

    Abstract: A method of decoding video data comprising parsing a sub-prediction unit motion flag from received encoded video data, deriving a list of sub-prediction unit level motion prediction candidates if the sub-prediction unit motion flag is active, deriving a list of prediction unit level motion prediction candidates if the sub-prediction unit motion flag is not active, and decoding the encoded video data using a selected motion vector predictor.
