Abstract: In general, techniques are described for coding picture order count values identifying long-term reference pictures. A video decoding device comprising a processor may perform the techniques. The processor may be configured to determine a number of bits used to represent least significant bits of the picture order count value that identifies a long-term reference picture to be used when decoding at least a portion of a current picture and parse the determined number of bits from a bitstream representative of the encoded video data. The parsed bits represent the least significant bits of the picture order count value. The processor retrieves the long-term reference picture from a decoded picture buffer based on the least significant bits, and decodes at least the portion of the current picture using the retrieved long-term reference picture.

Abstract: This disclosure describes techniques for selection of coded picture buffer (CPB) parameters used to define a CPB for a video coding device for clean random access (CRA) pictures and broken link access (BLA) pictures in a video bitstream. A video coding device receives a bitstream including one or more CRA pictures or BLA pictures, and also receives a message indicating whether to use an alternative set of CPB parameters for at least one of the CRA pictures or BLA pictures. The message may be received from an external means, such as a processing means included in a streaming server or network entity. The video coding device sets a variable defined to indicate the set of CPB parameters for a given one of the pictures based on the received message, and selects the set of CPB parameters for the given one of the pictures based on the variable for the picture.

Abstract: As one example, techniques for decoding video data include receiving a bitstream that includes one or more pictures of a coded video sequence (CVS), decoding a first picture according to a decoding order, wherein the first picture is a random access point (RAP) picture that is not an instantaneous decoding refresh (IDR) picture, and decoding at least one other picture following the first picture according to the decoding order based on the decoded first picture. As another example, techniques for encoding video data include generating a bitstream that includes one or more pictures of a CVS, wherein a first picture according to the decoding order is a RAP picture that is not an IDR picture, and avoiding including at least one other picture, other than the first picture, that corresponds to a leading picture associated with the first picture, in the bitstream.

Abstract: Techniques for encapsulating video streams containing multiple coded views in a media file are described herein. In one example, a method includes parsing a track of multiview video data, wherein the track includes one or more views, including only one of a texture view of a particular view and a depth view of the particular view. The method further includes parsing a track reference to determine a dependency of the track to a referenced track indicated in the track reference. Track reference types include ‘deps’ that indicates that the track includes the depth view and the reference track includes the texture view, ‘tref’ that indicates that the track depends on the texture view which is stored in the referenced track, and ‘dref’ that indicates that the track depends on the depth view which is stored in the referenced track.

Abstract translation: 这里描述了用于将包含多个编码视图的视频流封装在媒体文件中的技术。 在一个示例中，一种方法包括解析多视图视频数据的轨道，其中轨道包括一个或多个视图，其仅包括特定视图的纹理视图和特定视图的深度视图中的一个。 该方法还包括解析轨道参考以确定轨道与轨道参考中指示的参考轨迹的依赖关系。 轨道参考类型包括指示轨道包括深度视图的'deps'，并且参考轨道包括纹理视图，“tref”，其指示轨道取决于存储在所引用轨道中的纹理视图，而'dref' 这表示轨道取决于存储在参考轨道中的深度视图。
