Harmonization of deblocking conditions in video coding

A device for coding video data, the device comprising:

• a memory to store the video data;
• and
• one or more processors implemented in circuitry, the one or more processors configured to:
• determine a value of a first variable that indicates whether a coding mode of a first block of the video data is in a set of applicable coding modes, wherein determining the value of the first variable comprises determining that the value of the first variable indicates that the coding mode of the first block is not in the set of applicable coding modes based on a determination that the coding mode of the first block is not a block-based delta pulse code modulation (BDPCM) mode, a determination that the coding mode of the first block is not a transform skip mode, and a determination that the coding mode of the first block is not a palette mode;
• determine a value of a second variable that indicates whether a coding mode of a second block of the video data is in the set of applicable coding modes, wherein the second block is adjacent to the first block and determining the value of the second variable comprises determining that the value of the second variable indicates that the coding mode of the second block is not in the set of applicable coding modes based on a determination that the coding mode of the second block is not the BDPCM mode, a determination that the coding mode of the second block is not the transform skip mode, and a determination that the coding mode of the second block is not the palette mode;
• and
• determine that a deblocking filter is disabled for a color component of at least one of the first block or the second block based on at least one of:
• the value of the first variable indicating that the coding mode of the first block is in the set of applicable coding modes or the value of the second variable indicating that the coding mode of the second block is in the set of applicable coding modes.
