A device may include a video coder configured to determine an equivalent quantization parameter (QP) for a decoded block of video data using a quantization matrix for the decoded block of video data, determine deblocking parameters based on the determined equivalent QP, and deblock an edge of the decoded block based on the determined deblocking parameters. In particular, the video coder may determine equivalent QPs for two neighboring blocks defining a common edge, and deblock the common edge based on the equivalent QPs. The video coder may determine deblocking parameters, such as beta and tc values, based on the equivalent QPs. The video coder may then deblock the common edge based on the deblocking parameters, e.g., determine whether to deblock the common edge, determine whether to apply a strong or a weak filter to the common edge, and determine a width (in number of pixels) for a weak filter.
