Embodiment Construction

[0042] The basic idea of ​​the method of the present invention is: after the user selects to load the background sound and starts video recording using the mobile terminal, the mobile terminal analyzes the background sound file selected by the user and encodes the video frames obtained during the recording process, and then Write the parsed audio frames and encoded video frames alternately into the video file, and write the basic information required to play the above audio frames and video frames into the video file after the recording is completed. The basic information includes: encoding Information such as mode, total duration, starting position of the audio and video frame in the file, position of the key frame, and playback timestamp of the audio and video frame.

[0043] During specific implementation, the mobile terminal needs to provide a corresponding menu selection interface for the user to choose whether to load the background sound for the video file; The audio fi...

Abstract

The invention discloses a method and a mobile terminal for loading background sounds in a video recording process. The mobile terminal comprises a storage module, a human-computer interaction module, an audio file resolution module, a video frame coding module and a video recording file production module. The method comprises that: after a user selects background sound loading and starts video recording by using the mobile terminal, the mobile terminal resolves a background sound file selected by the user, codes a video frame acquired in the recording process, alternately writes a resolved audio frame and the coded video frame into a video recording file, and writes basic information required by the playing of the audio frame and the video frame into the video recording file after the recording is finished. By the method and the mobile terminal, user experiences are enriched, and a mobile phone is more powerful in photographing.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for loading background sound during video recording and a mobile terminal. Background technique [0002] With the development of technology, mobile phones are endowed with more and more additional functions. Whether to have these additional functions, and whether these additional functions provide a better user experience, has become one of the key factors that consumers consider when purchasing a mobile phone. One such key mobile phone addition is the mobile phone camera function. [0003] Currently, the video file format commonly used by mobile phones is 3gp. Such as figure 1 As shown, the 3gp format file is composed of several boxes, and can be nested, that is, one box can also store multiple other boxes. Among them, the 4 bytes at the beginning of each box are an integer, storing the length of the box; the next 4 bytes are a string, storing the type of the box...
