摘要： The example techniques described in this disclosure provide for an efficient manner to encode or decode a video block of a picture using a single reference picture list. The single reference picture list may include identifiers for reference picture or pictures used to encode or decode the video block. In some examples, a video encoder or decoder may encode or decode a video block that is predicted from two reference pictures using the single reference picture list, and encode or decode a video block that is predicted from one reference picture using the same, single reference picture list.

摘要： This disclosure relates to techniques for constructing a combined reference picture list, List C, based on List 0 and List 1, used for uni-directional prediction of video blocks in any direction. The techniques include coding one or more syntax elements defined to indicate construction information for List C, and performing reference picture list construction for List C from List 0 and List 1 based on the syntax elements. The one or more syntax elements may indicate that List C is used for uni-directional prediction, and may also indicate a number of reference pictures identified in List C and a reference index of a reference picture for each entry in List C. Each coded video block of a B slice may have an associated syntax element, i.e., inter_pred_idc, to indicate whether the video block is bi-predicted from List 0 and List 1 (Bi) or uni-directional predicted from List C (Pred_LC).

摘要： This disclosure relates to techniques for reducing a cost of coding prediction information in video coding. Video blocks in a generalized P/B (GPB) frame are encoded using up to two motion vectors calculated from reference pictures in two separate reference picture lists that are identical. When one of the reference picture lists is preferred over the other reference picture list, the preferred reference picture list may be used for unidirectional prediction, by default. When a GPB frame is enabled such that the first and second reference picture lists are identical, either of the first and second reference picture lists may be used for unidirectional prediction. The techniques include coding one or more syntax elements indicating that a video block is coded using one of the unidirectional prediction mode with respect to a reference picture in a reference picture list and the bidirectional prediction mode using less than two bits.

摘要： 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.
摘要翻译：视频编码器根据顺序执行处理一组边框像素的填充操作。该顺序从左下角的边框像素开始，并且顺序通过边框像素顺序到右上边框像素。当填补操作处理不可用边界像素时，填充操作基于先前由填充操作处理的边界像素的值来预测不可用边框像素的值。视频编码器可以基于边界像素生成帧内预测视频块。

摘要： The example techniques of this disclosure are directed to default construction techniques for the construction of a combined reference picture list, and default mapping techniques for the combined reference picture list. In some examples, a video coder may construct first and second reference picture lists from frame number values, and construct the combined reference picture list from the frame number values of the first and second reference picture lists. In some examples, a video coder may construct first and second reference picture lists from picture order count (POC) values, and construct the combined reference picture list from the POC values of the first and second reference picture lists. In some examples, a video coder may construct a combined reference picture list from received information for the construction, and map the pictures of the combined reference picture list to one of a first or second reference picture list.

The techniques also include constructing the first reference picture list based on the syntax elements, and then creating the second reference picture list as a duplicate of the first reference picture list.
