A video data stream having a video encoded thereinto is provided. The video data stream comprises an indication that indicates whether or not one or more scalable nesting supplemental enhancement information messages comprising timing information for each of one or more output layer sets are present within the video data stream.

An image processing method includes an electronic device that outputs a first frame rate when the electronic device detects that ambient light brightness in a current environment is less than or equal to a first preset light brightness threshold; collects first video data based on the first frame rate, where the first video data includes a plurality of frames of images; and performs frame interpolation on the frames of images to obtain and store second video data, where a frame rate of the second video data is greater than the first frame rate.

An apparatus (200) for receiving an input video data stream according to an embodiment is provided. The input video data stream has a video encoded thereinto. The apparatus (200) is configured to generate an output video data stream from the input video data stream.

This disclosure relates to video coding and more particularly to techniques for signaling picture output resolution for coded video. According to an aspect of an invention, a first flag syntax element indicating whether conformance cropping window offset parameters are present in a sequence parameter set is parsed, wherein the conformance cropping window offset parameters specify a cropping window that is applied to pictures with a width equal to a maximum width and a height equal to a maximum height.

A video processing method includes performing a conversion between a video comprising one or more pictures and a bitstream of the video according to a format rule. The format rule specifies that, in response to satisfying one or more conditions, a syntax element indicating whether a first syntax structure providing a profile, a tier and a level information and a second syntax structure providing decoded picture buffer information are present in a sequence parameter set is set to be equal to 1 to indicate that the first syntax structure and the second syntax structure are present in the sequence parameter set.
