Abstract
Examples include a device for coding video data, the device including a memory configured to store video data, and one or more processors configured to obtain adaptive loop filtering (ALF) information for a current coding tree unit (CTU) from one or more of: (i) one or more spatial neighbor CTUs of the current CTU or (ii) one or more temporal neighbor CTUs of the current CTU, to form a candidate list based at least partially on the obtained ALF information for the current CTU, and to perform a filtering operation on the current CTU using ALF information associated with a candidate from the candidate list. Coding video data includes encoding video data, decoding video data, or both encoding and decoding video data.
