摘要： The disclosure describes deblock filtering techniques. A video coder may determine an amount by which to deblock filter a pixel value of a pixel based on a geometrical distance from the pixel to a boundary and a pixel value difference between pixel values of at least two pixels. The video coder may then deblock filter the pixel based on the determined amount.

摘要： In general, this disclosure describes techniques for coding video blocks using a color-space conversion process. A video coder, such as a video encoder or a video decoder, may determine whether to use color-space conversion for a coding unit and set a value of a syntax element of the coding unit to indicate the use of color-space conversion. The video coder may apply a color-space transform process in encoding the coding unit. The video coder may decode the syntax element of the coding unit. The video coder may determine whether a value of the syntax element indicates that the coding unit was encoded using color-space conversion. The video coder may apply a color-space inverse transform process in decoding the coding unit in response to determining that the syntax element indicates that the coding unit was coded using color-space conversion.
