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 implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The Android platform adopts a hierarchical system architecture. From the upper layer to the lower layer, there are application program layer, application program framework layer (native layer), system runtime layer and Linux kernel layer, such as figure 1 shown. For the Android platform in the law enforcement recorder, according to its application needs, application modules such as a camera, a microphone, a communicator, an alarm, a clock, a calendar, and a media player are set in its application layer to meet the requirements of recording, Recording, intercom, alarm, date and time display, and audio and video media playback functions, etc.

[0028]For the microphone set in the law enforcement recorder, due to the limitation of the Android system programming, it can only be occupied by one application at the same...

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, it is a method for realizing video local storage and remote synchronous push proposed 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 intercom transmitter, and can digitally record dynamic and static scene conditions during law enforcement, which is convenient for public security officers. Used by law enforcement in a variety of environments. [0003] In recent years, law enforcement recorders have been used by more and more public security officers with the occurrence of some social events. When the existing law enforcement recorder records and videotapes the law enforcement scene, there are three processing methods for the audio data...
