Segmented video data processing method based on android system

Abstract

The invention discloses an Android system based segmented video data processing method. The method comprises a first step of collecting video frame data and audio frame data synchronously; a second step of coding the data through a hardware encoder; a third step of transmitting the coded data and a timestamp thereof to a segmented video module; a fourth step of writing the video frame data and audio frame data corresponding to the timestamp in a multi-media file; a fifth step of judging whether the time of the multi-media file reaches a preset maximum time, if yes, saving the multi-media file, if not, maintaining the fourth step; and a sixth step of creating a new multi-media file, using the last video frame of the previous multi-media file as a first video frame, and skipping to the fourth step. Through adoption of the method, time is not lost in the process, each frame is controlled strictly in recording of an MP4 file, so that the last frame of the previous video is definitely the first frame of the next video, and the two video files are consecutive.

Description

technical field [0001] The invention relates to the audio and video data collection of the Android system, in particular to a segmented video data processing method based on the Android system. Background technique [0002] The API (application programming interface) of the Android system is convenient and easy to use, but on the other hand, it will reduce the degree of freedom of development. For example, if you use the Android system API to develop segmented video recording, you must first open the multimedia recorder to record multimedia files, then close the multimedia recorder, and then reopen the multimedia recorder to record the next segment of multimedia files. In this way, a period of time must be lost between closing the multimedia recorder and reopening the multimedia recorder, so that the two sections of multimedia files are discontinuous, and the time lost between these two sections of multimedia files can reach as much as 1 to 3 seconds, while This lost time m...

In this way, a period of time must be lost between closing the multimedia recorder and reopening the multimedia recorder, so that the two sections of multimedia files are discontinuous, and the time lost between these two sections of multimedia files can reach as much as 1 to 3 seconds, while This lost time may be the key point of the accident, which will bring great inconvenience to the subsequent investigation of the case.
