1. A method for generating a media file including video information, the method comprising:
storing at least one of network adaptation layer (NAL) units including the video information in a track of a file format;
configuring a syntax of an operating point entity group in the file format, wherein the syntax of the operating point entity group includes information for the operation points; and
generating the media file based on the file format,
wherein the syntax of the operating point entity group includes flag information indicating whether a list of layers that belong to an output layer set related to the syntax of the operating point entity group is present or not, and
wherein based on a value of the flag information being equal to 1, the syntax of the operating point entity group includes information for specifying whether each layer in the output layer set is an output layer.
