Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0035] Usually, an MP4 format video file is composed of media description data and media data, and is encapsulated in a data block named box. The media description data defines the video aspect ratio, duration, bit rate, encoding format, frame list, key frame list, time stamp, and the position of the media data in the file. These information are all stored in a box named moov with a specific algorithm, and a moov box is composed of many boxes (such as mvhd box, trak box, etc.). After the moov box, the media data contains many audio and video media data stored in blocks. These audio and ...
