AHG9: On subpicture boundary handling
Abstract
This contribution proposes to unify the behavior of loop filter on subpicture boundary when subpicture is treated as picture, i.e., to always disable loop filter across subpicture boundaries between independent subpictures and enable loop filter across subpicture boundaries between dependent subpictures.
JVET-R0044 AHG9: On subpicture boundary handling [J. Li, K. Abe (Panasonic)]
This contribution proposes to change the behaviour of loop filter on subpicture boundary when subpicture is treated as picture, i.e., to always disable loop filter across subpicture boundaries between independent subpictures and enable loop filter across subpicture boundaries between dependent subpictures.
It was commented that if an encoder wants to indicate such behaviour, it can already do this. It would couple the inter prediction process with the post-decoding filtering process. This seemed undesirable, so no action was taken on this.
