Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] refer to Figure 1 ~ Figure 3 , a video file generating method for audio playback driving video recording, the method comprises the following steps:

[0044] (1) The speaker plays audio;

[0045] (2) When playing audio, according to the preset parameters, it will automatically stop after playing a file (a sub-file in a composite file), or the audio playback will be stopped by the UI at any time (including during and after playing a sub-file), or after a sub-file is played Automatically play the next sub-file after a few seconds after the file;

[0046] (3) the audio block is encoded (if the source file is Mp3, then directly copy the corresponding data before decoding and playing);

[0047] (4) Real-time acquisition of scene images;

[0048] (5) The collected image is marked with a watermark according to predetermined parameters, and encoded;

[0049] (6) Th...

Abstract

The invention discloses a video file generation method of an audio playing driving video. The method comprises the following steps: (1) using a loudspeaker to play audio; (2) when the audio is played,automatically stopping playing one file according to preset parameters, or stopping playing the audio at any time by the UI, or automatically playing the next sub-file at intervals of several secondsafter one sub-file is played completely; (3) coding the audio blocks; (4) collecting a scene image in real time; (5) printing watermarks on the collected images according to preset parameters, and carrying out encoding; and (6) forming a video file by integrating the played audio and the acquired image, and setting synchronization of five types of audio and video. Operation is simplified, and video files are automatically generated.

Description

technical field [0001] The invention relates to a method for generating video files. Background technique [0002] At present, the video production process is to first record the video and then perform dubbing and processing in the later stage. The post-dubbing and editing processing of this process is time-consuming and complicated. Contents of the invention [0003] In order to overcome the time-consuming and complicated shortcomings of existing video production methods, the present invention provides a video file generation method that simplifies operations and drives video recording by audio playback. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A video file generation method for audio playback driving recording, said method comprising the following steps: [0006] (1) The speaker plays audio; [0007] (2) When playing audio, according to the preset parameters, it will automatically stop after playing ...
