The frame per second rule of actual camera recorded video is:
(1), when the picture light recorded is normal, picture has normal change, and the frame per second at this moment recorded is 30
Frame is per second；
(2), when the picture light recorded is very dark, and picture is not changed in substantially, the frame per second at this moment recorded
It is that 13 frame left and right are per second.
Step A2, when timer arrives and specifies duration, it is judged that the video that video data encoding function receives
Whether the totalframes of data is to fix the frame number that frame per second is corresponding, the most then continue executing with step A3.
In this step, it is intended that duration could be arranged to 1 second, the frame number that fixing frame per second is corresponding can be 25
Frame.It is to say, when monitoring timer and arriving 1 second, it is judged that what video data encoding function received regards
Whether the totalframes of frequency evidence is 25 frames.
Step A3, by the coding video data of the video data encoding function totalframes to receiving, and
Restart timing.
In this step, if the totalframes of the video data of video data encoding function reception is 25 frames, then
By the coding video data of the video data encoding function totalframes (25 frame) to receiving, and again open
Beginning timing, returns and performs step A1.
Further, when timer arrives and specifies duration, if judging what video data encoding function received
The frame number that totalframes is corresponding more than fixing frame per second, then the video of the totalframes received from video data encoding function
Data abandon the video data of the frame number corresponding beyond fixing frame per second, by video data encoding function to residue
Coding video data, and restart timing.
It is exemplified as example, when monitoring timer and arriving 1 second, it is judged that video data encoding function with above-mentioned
The totalframes of the video data received is more than 25 frames, it is assumed that is 28 frames, then connects from video data encoding function
The video data of the totalframes (28 frame) received abandons the frame number (25 frame) corresponding beyond fixing frame per second
Video data, i.e. abandons the video data beyond 3 frames, by video data encoding function to remaining video counts
Encode according to (video datas of 25 frames), and restart timing, return and perform step A1.
Further, when timer arrives and specifies duration, if judging what video data encoding function received
The frame number that totalframes is corresponding less than fixing frame per second, then arrive by timer in video data acquiring device when specifying duration
The last one-frame video data transmitted constantly sends video data encoding function to, until video data
The frame number that the totalframes that coding function receives is corresponding equal to fixing frame per second；When the reception of video data encoding function
During the totalframes frame number corresponding equal to fixing frame per second, by regarding of the video data encoding function totalframes to receiving
Frequency is according to encoding, and restarts timing.
It is exemplified as example, when monitoring timer and arriving 1 second, it is judged that video data encoding function with above-mentioned
The totalframes of the video data received is less than 25 frames, it is assumed that be 23 frames, then regard when being arrived 1 second by timer
Frequently the one-frame video data that data acquisition unit transmits for the last time constantly sends video data encoding function to,
Until the totalframes that video data encoding function receives is equal to the frame number (25 frame) that fixing frame per second is corresponding；When regarding
During the totalframes that frequency receives according to coding function frame number (25 frame) corresponding equal to fixing frame per second, by video counts
According to the coding video data of the coding function totalframes to receiving, and restart timing, return and perform
Step A1.
In an embodiment of the present invention, in order to improve the accuracy and efficiency of coding, at video data acquiring device
During often collection one-frame video data is conveyed to video data encoding function, abandon the video of designated frame
Data, this designated frame is the 6th frame.
In an embodiment of the present invention, above-mentioned coded system can use following algorithm to realize:
A, carries out counting numbering no to the video data recorded；
If (no%6==0)
Abandon this frame of video
Else
Send frame of video to encoder (that is, video data encoding function)
B, starts 1 second timer, records timer corresponding number of times respond_no, adds up to give coding
The video frame number of device；
encoded_no
Respond_no*25 is the frame number that output video needs
If frame number error is missframe_no
Missframe_no=respond_no*25 encoded_no
if(missframe_no>0)
{ frame number that coding completes, less than the frame number being actually needed, at this moment needs to increase frame of video, it is simply that same
One uncoded frame of video copies many parts to encoder }
else if(missframe_no<0)
{ frame number that coding completes, more than the frame number being actually needed, at this moment needs to reduce frame of video, namely to the greatest extent
Amount abandons some frames more }
