Abstract: Systems, methods, and devices for processing video data are disclosed. A message is received at a video decoding device, the message comprising an external indication from a source device external to the video decoding device. A video bitstream is received at the video decoding device, wherein the video bitstream comprises compressed video data and wherein the video bitstream is received separately from the message. A value of a HandleCraAsBla flag is set to a value specified by the message and CRA pictures are processed as BLA pictures based on the value of the HandleCraAsBla flag. A value of a second flag is set based on the value of the HandleCraAsBla flag, the second flag being indicative of whether at least one picture decoded prior to decoding of the CRA picture is to be output.

Abstract: Techniques for advanced residual prediction (ARP) for coding video data may include inter-view ARP. Inter-view ARP may include identifying a disparity motion vector (DMV) for a current video block. The DMV is used for inter-view prediction of the current video block based on an inter-view reference video block. The techniques for inter-view ARP may also include identifying temporal reference video blocks in the current and reference views based on a temporal motion vector (TMV) of the inter-view reference video block, and determining a residual predictor block based on a difference between the temporal reference video blocks.

Abstract: A video coder is configured to apply a separable bilinear interpolation filter when determining reference blocks as part of advanced residual prediction. Particularly, the video coder may determine, based on a motion vector of a current block in a current picture of video data, a location of a first reference block in a first reference picture. The video coder may also determine a location of a second reference block in a second reference picture. The video coder may apply a separable bilinear interpolation filter to samples of the second reference picture to determine samples of the second reference block. The video coder may apply the separable bilinear interpolation filter to samples of a third reference picture to determine samples of a third reference block. Each respective sample of a predictive block may be equal to a respective sample of the first reference block plus a respective residual predictor sample.

Abstract: A video encoder generates, based on a reference picture set of a current view component, a reference picture list for the current view component. The reference picture set includes an inter-view reference picture set. The video encoder encodes the current view component based at least in part on one or more reference pictures in the reference picture list. In addition, the video encoder generates a bitstream that includes syntax elements indicating the reference picture set of the current view component. A video decoder parses, from the bitstream, syntax elements indicating the reference picture set of the current view component. The video decoder generates, based on the reference picture set, the reference picture list for the current view component. In addition, the video decoder decodes at least a portion of the current view component based on one or more reference pictures in the reference picture list.

Abstract: A video decoder generates an initial reference picture list (RPL). Furthermore, the video decoder determines that an ordered set of reference picture list modification (RPLM) syntax elements does not include any additional syntax elements when a syntax element in the ordered set of RPLM syntax elements has a particular value. Furthermore, the video decoder generates a final RPL. For each respective RPLM syntax element in the ordered set of syntax elements, when the respective RPLM syntax element does not have the particular value, the final RPL includes, at an insertion position for the respective RPLM syntax element, a particular reference picture. The respective syntax element indicates a position in the initial RPL of the particular RPLM reference picture. The insertion position for the respective RPLM syntax element corresponds to a position in the ordered set of RPLM syntax elements of the respective RPLM syntax element.

Abstract: A video encoder generates a bitstream that includes a reference picture list modification (RPLM) command. The RPLM command belongs to a type of RPLM commands for inserting short-term reference pictures into reference picture lists. The RPLM command instructs a video decoder to insert a synthetic reference picture into the reference picture list. The video decoder decodes, based at least in part on syntax elements parsed from the bitstream, one or more view components and generates, based at least in part on the one or more view components, the synthetic reference picture. The video decoder modifies, in response to the RPLM commands, a reference picture list to include the synthetic reference picture. The video decoder may use one or more pictures in the reference picture list as reference pictures to perform inter prediction on one or more video blocks of a picture.
