Abstract: A mechanism for processing video data implemented by a video coding apparatus is disclosed. The mechanism determines to split a coding tree unit (CTU) into one or more coding units (CUs). One or more of the CUs may be one or more prediction tree units (PTUs). The mechanism further determines to recursively split the CUs into prediction units (PUs). The method performs a conversion between a visual media data and a bitstream based on the PUs.

Abstract: A mechanism for processing video data implemented by a video coding apparatus is disclosed. The mechanism determines to apply a prediction splitting tree to a prediction tree unit (PTU). The prediction splitting tree includes a leaf prediction unit (PU). A prediction mode is selected for the leaf PU based on whether the leaf PU is split from the PTU. The method performs a conversion between a visual media data and a bitstream based on the leaf PU.

Abstract: Video processing methods, systems and appratrus are described. One example method includes performing a conversion between a video block of a video and a bitstream of the video using a palette mode in which samples of the video block are represented using a palette of representive color values. A size of the palette of the video block is determined based on whether a local dual tree is applied for the conversion.

Abstract: A method of video processing is provided. The method includes determining, for a conversion between a video comprising a video unit and a bitstream of the video, whether a first coding tool is enabled for the video unit according to a rule. The rule specifies that the first coding tool and a second coding tool are mutually exclusively enabled. The first coding tool or the second coding tool comprises a sign data hiding tool. The method also includes performing the conversion according to the determining.

Abstract: A method implemented by a video coding apparatus. The method includes determining that a scalability dimension information (SDI) supplemental enhancement information (SEI) message precedes a multiview acquisition information (MAI) SEI message in decoding order whenever an access unit (AU) contains both the SDI SEI message and the MAI SEI message; and performing a conversion between a video and a bitstream of the video based on the SDI SEI message and the MAI SEI message. A corresponding video coding apparatus and non-transitory computer readable medium are also disclosed.

Abstract: A mechanism for processing video data is disclosed. A conversion is performed between a visual media data including a plurality of video units and a bitstream. A guided filter is applied to samples in the video units. The guided filter is applied at a post decoding stage, such as in an in-loop filtering process.

Abstract: A method for coding video data implemented by a video coding apparatus. The method includes filling an extended area disposed around a video unit with padding samples to generate a larger video unit. Some of the padding samples are generated without duplicating boundary samples within the video unit. The method further includes converting between the video unit of the video and a bitstream in accordance with the extended area as filled.
