Abstract: A video coder performs a padding operation that processes a set of border pixels according to an order. The order starts at a bottom-left border pixel and proceeds through the border pixels sequentially to a top-right border pixel. When the padding operation processes an unavailable border pixel, the padding operation predicts a value of the unavailable border pixel based on a value of a border pixel previously processed by the padding operation. The video coder may generate an intra-predicted video block based on the border pixels.

Abstract: Aspects of this disclosure relate to, in an example, a method that includes identifying a first block of video data in a first temporal location from a first view, wherein the first block is associated with a first disparity motion vector. The method also includes determining a motion vector predictor for a second motion vector associated with a second block of video data, wherein the motion vector predictor is based on the first disparity motion vector. When the second motion vector comprises a disparity motion vector, the method includes determining the motion vector predictor comprises scaling the first disparity motion vector to generate a scaled motion vector predictor, wherein scaling the first disparity motion vector comprises applying a scaling factor comprising a view distance of the second disparity motion vector divided by a view distance of the first motion vector to the first disparity motion vector.

Abstract: Un codificador de video ejecuta una operación de relleno que procesa un conjunto de píxeles de borde de acuerdo con un orden; el orden inicia en un píxel de borde inferior-izquierdo y procede a través de los píxeles de borde en secuencia a un píxel de borde superior-derecho; cuando la operación de relleno procesa un pixel de borde no disponible, la operación de relleno predice un valor del pixel de borde no disponible con base en un valor de un píxel de borde previamente procesado por la operación de relleno; el codificador de video puede generar un bloque de video intra-pronosticado con base en los píxeles de borde.

Abstract: In an example aspects of this disclosure generally relate to a method of coding video data that includes determining a first bit depth for outputting video data and a second bit depth for coding the video data wherein the first bit depth is less than the second bit depth. The method also includes determining whether the video data will be used as reference data when coding other video data. The method also includes storing based on the determination the video data at the first bit depth when the video data is not used as reference data and the video data at the second bit depth when the video data is used as reference data.

Abstract: This disclosure describes techniques for quantizing coefficients of a video block for a video coding process that supports context-based adaptive binary arithmetic coding (CABAC). A method may comprise estimating a last non-zero coeffi-cient of the video block, and generating a set of quantized coefficients for the video block based on an assumption that the esti-mated last non-zero coefficient is actually the last non-zero coefficient of the video block.

Abstract: In general, this disclosure describes techniques for coding video data for random access. In particular, this disclosure proposes to code a syntax element that indicates if a dependent picture may be successfully decoded in the event of a random access request to a clean decoding refresh (CDR) picture and may be required for decoding the pictures following the clean decoding refresh (CDR) picture in display order.
