Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Video formats are classified into two types, video coding formats and video packaging formats. Video coding is a process of compressing the original data decoded from a camera or video into a format of a specific format specification, such as the common h.264, h.265 and national standard AVS format standards. Video encapsulation is to encapsulate data such as video stream, audio stream and subtitle into a file for distribution and playing, such as common MP4, AVI, MKV and other formats.
The IVF format is extended based on the MP4 format, and all file resources required by the interactive video are packaged. The MP4 format adopts the Box concept to organize metadata information and coded data required by audio and video decoding. Such as an MP4 file organized as a Box as follows. First, ftyp Box, defining the file type, followed by moov, free, mdat three top-level boxes. In moov Box, nest defines mvhd, track, etc. Box, and then other boxes are defined by inner nest.

The Box definition format may be as follows according to the character sequence: 4Bytes Size,4Bytes Type = 'box name', 1Byte Version,3Bytes Flags.
In this embodiment, the data record container may be named Ivfh box, and is used to record metadata of the media asset file related to the IVF format. The media resource file may include a conventional video file, a vector video file, an audio file, an interactive component related file (such as a button picture related to an interactive component), a scenario configuration file, a logic code file, and the like, which form the target interactive video file. The specific format of Ivfh box can be as shown in table 1.
TABLE 1
The standard definition is referred to as follows:
