Abstract: A video decoder may be configured to determine a reference block for a current block of a current picture of video data, wherein the reference block is in the current picture; determine a prediction block based on the reference block; determine whether to apply filtering to the prediction block; based on determining that the filtering is to be applied to the prediction block, compare a template of the reference block to a template of the current block and filter the prediction block based on the comparing of the template of the reference block to the template of the current block to determine a filtered prediction block; decode the current block based on the filtered prediction block to determine a decoded version of the current block; and output a decoded picture of the video data comprising the decoded version of the current block.

Abstract: An example video coding device is configured to: code a first set of motion information for a current block of video data partitioned into a first partition and a second partition according to a non-rectangular partition mode, the first set of motion information referring to a reference picture list and being associated with the first partition; after coding the first set of motion information, code a second set of motion information for the current block referring to the reference picture list and that is associated with the second partition; in response to the first set of motion information and the second set of motion information both referring to the reference picture list, store the second set of motion information for the current block; and predict subsequent motion information of a subsequent block of the video data that neighbors the current block using the stored second set of motion information.

Abstract: Se describen técnicas para las operaciones de la lista de candidatos basada en el historial en la codificación de video para determinar información de movimiento para un bloque actual. En un ejemplo, un dispositivo para decodificar datos de video incluye una memoria configurada para almacenar una lista de candidatos basada en el historial y un decodificador de video. El decodificador de video está configurado para construir la lista de candidatos basada en el historial almacenando, en la memoria, la información de movimiento de los bloques reconstruidos en la lista de candidatos basada en el historial como candidatos de la lista de candidatos basada en el historial, identificar un subconjunto de candidatos de la lista de candidatos basada en el historial, generar una lista de candidatos basada en el subconjunto identificado de candidatos de la lista de candidatos basada en el historial y reconstruir un bloque actual basado en la lista de candidatos generada.

Abstract: Techniques are described for history-based candidate list operations in video coding for determining motion information for a current block. In one example, a device for decoding video data includes a memory configured to store a history-based candidate list and a video decoder. The video decoder is configured to construct the history-based candidate list by storing, in the memory, motion information of reconstructed blocks into the history-based candidate list as candidates of the history-based candidate list, identify a subset of candidates of the history-based candidate list, generate a candidate list based on the identified subset of candidates of the history-based candidate list, and reconstruct a current block based on the generated candidate list.

Abstract: A video coder is configured to use bi-directional optical flow (BDOF) to determine, based on a first reference picture and a second reference picture, a prediction block for a current block of a current picture of the video data. The first reference picture is a first picture order count (POC) distance from the current picture. The second reference picture is a second POC distance from the current picture. A constraint is imposed by a video coding standard, the constraint requiring the first POC distance to be equal to the second POC distance. The video coder codes, according to the video coding standard, the current block based on the prediction block for the current block.
