Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
In a kind of processing method embodiment one disclosed in the present application, as shown in Figure 1, method includes the following steps:
Step 101: obtaining initial video file, initial video file includes image sequence, and image sequence includes initial graph
Picture and differential image, differential image include the variance data at least between initial pictures.
Firstly, method disclosed in the present embodiment can be applied to the server-side of monitor video storage system, specially set
It is placed in the service equipment of network side, can be realized by single server, can also be realized by the server farm that multiple servers form,
The present embodiment does not limit this.And method disclosed in the present embodiment is without rising the hardware system and tool of server-side
Grade, has brought a large amount of memory space with minimum calculating cost.
Secondly, initial video file is compressed monitor video file, generally compressed using H264 coding, it is subsequent
It is illustrated so that H264 is encoded as an example.H264 coding is introduced below:
H264 coding mainly considers the temporal correlation of video, the basic principle is that: such as with monitor video file
First frame is start frame, and subsequent frame refers to the frame of front, only difference (place of movement) recorded, to reach the effect of video compress
Fruit.
To reduce frame losing (such as Network Packet Loss, corrupted data), the influence to entire monitor video such as prediction error, video
The concept of GOP (Group of pitcures) is introduced in coding.One GOP indicates a decodable image sequence, generally
It is made of 1 I frame, several P frames and B frame.The image sequence that initial video file is included in the present embodiment is one
A GOP, the initial pictures that corresponding image sequence is included are I frame, the differential image that is included is at least P frame.Below to I
Frame, P frame and B frame do simple introduction:
I frame: key frame does not depend on other frames, and compression ratio is generally 1/7；
P frame: single directional prediction frame, I frame or P frame, compression ratio before relying on can achieve 1/20~1/30；
B frame: bi-directional predicted frames, I frame or P frame, compression ratio before and after dependence can achieve 1/150~1/200.
It, can be by the way of GOP configuration, with M (P interframe finally, for the setting of image sequence in initial video file
Every)=3, for N (I frame period)=13, the example of initial video file is as shown in Figure 2, wherein I, B, P respectively indicate I frame, B
Frame and P frame.
Step 102: key frame detection being carried out to image sequence, and is given birth in image sequence there are in the case where key frame
At the mark video frame for identifying key frame, key frame includes at least frame image in initial pictures and differential image.
Firstly, key frame can be pre-assigned by the user, including at least frame figure in initial pictures and differential image
Picture, that is to say, that, it is possible to specify belong to the video frame of at least one of I frame, P frame and B frame as key frame.Certainly, it is based on
Above to the description of GOP, can determine I frame for B frame and P frame, compression ratio is very low, possessed compression space very
Greatly.Therefore, key frame includes at least initial pictures, that is, belongs to the video frame of I frame.
Secondly, key frame detection is introduced below:
The initial video file that H264 is encoded is in a network with NALU format transmission, in initial video file
Some video frame can determine belonging to the video frame by the low 5 bit NAL TYPE of byte where detecting its NAL
Type, I frame or P frame or B frame.
By taking key frame is to belong to the video frame of I frame as an example, for the GOP1 in the initial video file shown in Fig. 2, such as
Fruit detects that video frame 1 is I frame in GOP1, then can determine that the video frame 1 is key frame, to generate for identifying video frame
1 mark video frame specifically carries the mark of video frame 1 in the mark video frame.The mark can be the position of video frame 1
It sets, can also be the serial number etc. of video frame 1, the present embodiment does not limit this, can be with unique identification video frame 1.
Step 103: the key frame in initial video file being replaced with into mark video frame and obtains the first video file.
Continue so that key frame is to belong to the video frame of I frame as an example, the GOP1 in initial video file shown in Fig. 2 is come
It says, extracts video frame 1 from initial video file first, and then mark video frame corresponding to video frame 1 is set to view
1 position of frequency frame.And the mark due to only carrying video frame 1 in mark video frame, for video frame 1,
Memory space shared by it is much smaller.At this point, memory space shared by the first video file is also just much smaller than initial video text
Memory space shared by part.
In addition, for other video frames for being not belonging to I frame in initial video file, it can be without any processing.
Step 104: processing key frame obtains the second video file, and the second video file includes initial key frame and difference
Key frame, difference key frame include the variance data at least between initial key frame, and the mark view in the first video file
Frequency frame initial key frame corresponding with the key frame identified/difference key frame has incidence relation.
Continue so that key frame is to belong to the video frame of I frame as an example, it is assumed that there are 10 GOP in initial video file shown in Fig. 2,
I.e. GOP1, GOP2 ... and GOP10.By step 103 can respectively from GOP1, GOP2 ... and extracted respectively in GOP10
Out a video frame 1, video frame 2 ... and video frame 10.Can obtain at this time one by video frame 1, video frame 2 ... and
The key frame file that video frame 10 is constituted, and then compression processing can be carried out to the key frame file using specified coded format
Obtain the second video file.
Wherein, specified coded format can be H264 coding, H265 coding, any one in MPEG, continue with
It is illustrated for H264 coding:
Assuming that the GOP of the second video file is configured to M (P frame period)=1, N (I frame period)=5, then the second video file
Example it is as shown in Figure 3, wherein I, B, P respectively indicate I frame, B frame and P frame.As can be seen that belonging to I frame in the second video file
Video frame be initial key frame, the video frame for belonging to B frame or P frame is difference key frame, difference included by difference key frame
Heteromerism is according to that can refer to the above-mentioned introduction for B frame and P frame, and details are not described herein.
In addition, can further generate key frame record sheet, the key frame record sheet to visualize above-mentioned incidence relation
Middle record has above-mentioned incidence relation.
For the application effect for embodying the application, M (P frame period)=3, N (I frame are configured with the common GOP of current monitor video
Interval)=60 for, it is assumed that every frame data amount is F (MB), and the frame per second of camera is 20FPS, and stores 1 month data IB
B B P B B B P B B B P B B B P B B B P B B B P B B B P B B B…。
Use the size of initial video file before the application:
S1=F* (1/7+14*1/30+45*1/200) * (20*3600*24*30)/30 (MB)
Use the size reduced after the application:
S2=F (1/7) * (20*3600*24*30)/30-F* (20*3600*24*30/30)/200 (MB)
It can then calculate using the space proportion saved after the application:
S2/S1=(1/7-1/200)/(1/7+14*1/30+45*1/200)=16.52%.
Following table 1 be using the application after, commonly use GOP and configure corresponding effective effect table:
| GOP list | Save memory space % |
| M=3, N=30 | 28.354554 |
| M=2, N=30 | 25.394737 |
| M=3, N=60 | 16.519258 |
| M=2, N=30 | 14.121951 |
| M=3, N=90 | 11.654589 |
| M=4, N=90 | 13.610719 |
| M=3, N=120 | 8.8396947 |
| M=4, N=120 | 9.9211789 |
