Description
Technical field
The present invention relates to a kind of continuous recording system based on Android system and method, belong to computer media neck
Domain.
Background technology
The video recording assembly that Android system provides does not have the function of continuously recording.Stopping is needed to lay equal stress on during switching file
Open video recording.Continuously recording cannot be accomplished.When the present invention solves Android system video recording switching file, need to stop and reopen record
Picture, leads to the discontinuous problem of Video content in adjacent file.
Present invention explanation will switch file in recording, the recorded content of adjacent file is that continuously this characteristic is recorded continuous
System.
In the product form of drive recorder or intelligent back vision mirror, from the point of view of system type, it is divided into mini system and intelligence
System., mainly based on embedded Linux, intelligence system is at present based on android for mini system.
Some cheap drive recorders then employ the scheme of approximate continuous video recording it is simply that first stopping video recording preservation in the industry
One file, is then starting new video recording, midfeather is generally within 1s, but the video recording of this period is to lose.But
Also minority scheme has and can accomplish real continuously recording, and the product that these enable continuously recording typically uses mini system.
Some producers, because cannot realize continuously recording in android, just take the scheme of dual system, use mini system
To record a video, intelligence system and used as panel computer.
Therefore using mini system and former android assembly video recording is carried out the problems of continuously recording following (1)-
(3) shown in, comprising:
(1) although mini system can be realized being continuously recording, the single function of mini system, competitiveness is low；
(2) mini system+intelligence system, high cost；
(3) the primary video recording assembly of android cannot meet the requirement of continuously recording.The compatible numerous applications of intelligence system, can
The function of being needed by installing application to complete, platform expansibility is strong.Realizing continuously recording in intelligence system is to allow intelligence
System can become the precondition of drive recorder carrier.
The present inventor also retrieves a Patent No. 201310420127.4, invention entitled " a kind of
The method of android terminal Automatic continuous video recording and terminal ", shown in following (4)-(6) of its inventive point, comprising:
(4) pass through to allow user before recorded video, the RECORD mode that can select present terminal is Automatic continuous RECORD mode
Or for traditional RECORD mode so that user can select suitable RECORD mode according to actual demand, and then good lifting
Operating experience.
(5) Automatic continuous are recorded a video in opening, and terminal is in carrying out video process, if the current video file recorded
Size reaches the maximum threshold values of Android system permission, and system is then automatically stopped and preserves the video currently recorded, and under starting
The recording of one video.Therefore, user, without worrying oneself not by terminal, leads to screen to be recorded to Android system and allows
Maximum threshold values when, be automatically stopped video recording, without being recorded to the problem of follow-up highlight scene, effectively the making of lifting user
With experience.
(6) can make android terminal video recording operate easier, user, need not be anti-in long-time recorded video
The multiple video file preserving recording manually, need not repeatedly open video recording, improve the intellectuality of android terminal, optimize use
The video recording experience at family.
The present inventor thinks shown in following (7)-(8) of shortcoming that prior art exists, comprising:
(7) the method cannot accomplish real continuously recording.It is to detect that stopped records a video to trigger again to record a video next time.So phase
A part of data can be lost between adjacent file.It uses the primary recording function of android.This programme then realizes record again
As function, will not stop gathering during switching file, be merely only the switching carrying out file, the frame between adjacent file
It is continuous；
(8) time of switching file can not control.The program can only arrive maximum file and could switch file.This programme then can be appointed
The next file of meaning duration switching.
