Problems solved by technology

It can be seen that the complicated process of switching the front and rear cameras will lead to a long time-consuming
What's worse is that the two files are stored separately, and the user hopes to save them in the same file, which deviates from the user's original intention. Even if they can be merged together through post-production, the operation is very cumbersome
[0006] To sum up, the existing multi-camera shooting video technology obviously has inconvenience and defects in actual use, so it is necessary to provide a technical solution that enables users to quickly switch between different cameras in order to obtain a wider viewing angle

Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] see figure 2 and Figure 4 , in the first embodiment of the present invention, a device 100 for shooting and video recording is provided, including:

[0041] The shooting mode switching unit 10 is used to start the fast switching shooting mode, and in the fast switching shooting mode, the video recording data input source of the video recording module is the screen display module;

[0042] The encoding unit 20 is used for initializing the encoder and creating a recording thread, performing data encoding on the preview data output by the screen display module, and generating a recording fi...

Abstract

The invention is suitable for the technical field of communication, and provides a video recording method and device. The video recording method includes the recording mode switching step and the coding step, wherein the recording mode switching step includes the step of starting a rapid switching recording mode, a video data input source of a video module serves as a screen display module in the rapid switching recording mode, and the coding step includes the steps of initializing a coder, creating a video thread, conducting data coding on preview data output by the screen display module, and generating a video file. In this way, according to the video recording method and device, a user can rapidly switch a plurality of cameras in the video recording process in the rapid switching recording mode.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for switching between multiple cameras to shoot and video. Background technique [0002] see figure 1 , the existing recording framework such as figure 1 Shown: After the camera (camera) collects data, it is divided into two independent data channels, one is used for viewfinder preview, and the other is used for video encoding. The preview data is sent to Surface Flinger (screen display module), superimposed with other GUI (Graphical User Interface, Graphical User Interface) icons, sent to HW Composer (Hardware Composer, hardware designer) for synthesis, and finally sent to LCD (Liquid Crystal Display, liquid crystal display) for display. The recording data is first sent to the Media Recorder (recording module), and the recording module will call the underlying encoder Encoder (encoding module) module, and the Encoder module will compress t...
