    Abstract: A method of processing media data. The method includes determining, for a dependent random access point (DRAP) sample, a first sequence of samples; and performing a conversion between media data and a media data file based on the determining. The first sequence of samples consists of the following samples in order: 1) a closest preceding stream access point (SAP) sample of type 1, type 2, or type 3; 2) the DRAP sample; and 3) all samples following the DRAP sample in both decoding order and output order in a first track.

    Abstract: Methods, systems and devices for using end of sequence indications are described. An example method of video processing includes performing a conversion between a video and a bitstream of the video, wherein the bitstream includes multiple layers in multiple access units, AUs, including one or more pictures according to a format rule, wherein the format rule specifies that, responsive to an end of sequence (EOS) network abstraction layer (NAL) unit for a first layer being present in a first access unit (AU) in the bitstream, a subsequent picture of each of one or more higher layers of the first layer in an AU following the first AU in the bitstream is a coded layer video sequence start (CLVSS) picture.

    Abstract: Embodiments of the present disclosure provide a solution for media processing. A method for media processing comprises: performing a conversion between a media file of a media and a media presentation of the media, wherein each main stream representation (MSR) in the media presentation is associated with an external stream representation (ESR) in the media presentation. Compared with the conventional solution, the proposed method can advantageously support the extended dependent random access point (EDRAP)-based technology more efficiently.

    Abstract: Systems, methods and apparatus for video processing are described. The video processing may include video encoding, video decoding, or video transcoding. One example method of video processing includes performing a conversion between a video including one or more pictures and a bitstream of the video according to a format rule. The format rule specifies that a first syntax element that indicates whether motion vector difference for a particular reference picture list (RPL) is indicated is conditionally included in the bitstream based on (i) whether a second syntax element indicating whether an RPL information is included in a picture header and/or (ii) a number of reference pictures in the particular RPL in case that the RPL information is present in the picture header.
