Problems solved by technology

At this time, since the microphone has been occupied by the MediaRecoder application, other applications will not be able to use the microphone to obtain the audio data output by it, so the audio data will not be pushed to the remote command center, so that local storage and remote push can be synchronized.

Embodiment Construction

[0026] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0027] The Android platform adopts a hierarchical system architecture. From the upper layer to the lower layer, it is the application layer, the application framework layer (native layer), the system runtime layer and the Linux kernel layer, such as figure 1 shown. For the Android platform in the body-worn recorder, according to its application needs, application modules such as camera, microphone, talker, alarm, clock, calendar, media player, etc. are set in the application layer to meet the needs of the body-enforcement recorder's recording, Video recording, intercom, alarm, date and time display, and audio and video media playback functions.

[0028]For the microphone set in the body camera, due to the limitation of Android system programming, it can only be occupied by one application at the same time, that is, there is a proble...

Abstract

The invention discloses a local video recording and synchronously pushing method based on an Android platform, and a law enforcement recorder. Original audio data output by a microphone and the original video data collected and output by a camera are directly acquired on an application layer and are automatically performed with pre-compiling, encoding and packaging, so that the problem that the microphone is occupied by a MediaRecorder application when starting a video recording function, resulting in from that other applications cannot obtain audio signals, can be avoided. When the video recording function is started, the original audio data are automatically obtained, and the obtained original audio data and video data are performed with pre-compiling, encoding and packaging by autonomously created audio and video preprocessing module, an audio and video encoder and an audio and video shunt, so that two paths of completely synchronous audio and video data streams can be generated, one path is applied to remote real-time transmission, and the other path is applied to local storage so as to solve the problem of local video recording and synchronously pushing of audio and video streams.

Description

technical field [0001] The invention belongs to the technical field of police law enforcement equipment, in particular to a method for realizing local storage of video recordings and remote synchronous push for a law enforcement recorder developed based on an Android platform. Background technique [0002] Law enforcement recorder, also known as police law enforcement recorder or on-site law enforcement recorder, integrates the functions of digital camera, digital camera, and walkie-talkie transmitter. Law enforcement use in a variety of settings. [0003] In recent years, law enforcement recorders have been used by more and more police officers with the occurrence of some social events. There are three processing methods for the audio data and video data collected by the microphone and the camera when the existing body recorder records and records the law enforcement scene: [0004] First, save the audio and video data collected on site locally, that is, in the law enforc...
