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.

For example, a method of decoding video data includes accessing an encoded video bitstream comprising multiple layers. The encoded video bitstream includes multiple access units, with a first access unit including an end of sequence network abstraction layer unit. A second access unit includes an intra random access point picture and is a next subsequent access unit in decoding order following the first access unit. The method further includes reinitializing decoding at the second access unit based on the second access unit being the next subsequent access unit in decoding order following the end of sequence network abstraction layer unit of the first access unit.

Abstract: Techniques and systems are provided for encoding video data. For example, a method of encoding video data includes generating an encoded video bitstream comprising multiple layers. The encoded video bitstream includes one or more sequence parameter sets and a video parameter set. The method further includes generating, according to a constraint, one or more representation format parameters for a sequence parameter set assigned to a base layer of the encoded video bitstream. The constraint limits values of the one or more representation format parameters in the sequence parameter set to be less than or equal to values of corresponding representation format parameters that are assigned to the base layer in the video parameter set.

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 computing device generates a file that comprises a media data box that encloses media content. The media content comprises a sequence of samples. Each of the samples is an access unit of multi-layer video data. Responsive to a determination that at least one access unit of a bitstream of the multi-layer video data includes a coded picture that has a picture output flag equal to a first value and a coded picture that has a picture output flag equal to a second value, the computing device uses at least two tracks to store the bitstream in the file. For each respective track from the at least two tracks, all coded pictures in each sample of the respective track have the same value of the picture output flag.
