When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistented with the present invention.On the contrary, they be only with it is such as appended
The example of device and method being described in detail in claims, some aspects of the invention are consistent.
In order to solve prior art problem, the embodiment of the present application provide a kind of method for video coding, video encoding/decoding method,
Device, electronic equipment and system.
A kind of method for video coding provided by the embodiment of the present application is introduced first below.
It should be noted that a kind of method for video coding provided herein can be applied in electronic equipment.Having
In body application, which can be terminal device or server.In addition, a kind of method for video coding provided herein
Targeted video can be any one video to be encoded, and the application does not limit source, the content etc. of video to be encoded
It is fixed.
Fig. 1 is a kind of flow chart of method for video coding shown according to an exemplary embodiment.As shown in Figure 1, this Shen
Please a kind of method for video coding provided by an exemplary embodiment, may include steps of:
S101, during being encoded to video, for target frame to be encoded, if detect the target frame it
Continuous N frame is identical as the target frame afterwards, carries out preset frame level coding to the target frame and continuous N frame；
Wherein, N is more than or equal to 1, frame level coding are as follows: block grade coding is carried out to the frame in the target frame and continuous N frame,
And the quantity for carrying out frame level to the quantity of the corresponding repeating frame of the target frame is stated.
During being encoded to video, can putting in order according to video frame, successively to each video frame into
Row coding.It is understood that first target frame to be encoded encoded using the provided coding method of the present embodiment,
It can be the first frame of the video.Certainly, encoded using the provided coding method of the present embodiment first is to be encoded
Target frame, it is not limited to the first frame of video, for example:, can be by a certain of the video according to scheduled code requirement
First frame in multiple video frames of period, as first encoded using the provided coding method of the present embodiment wait compile
The video frame of code.
It is not block grade coding directly to be carried out to the target frame, but examine for target frame to be encoded in the present embodiment
It surveys after the target and whether there is that continuous N frame is identical as the target frame, which includes the next frame of the target frame.In turn,
If continuous N frame is identical as the target frame after detecting the target frame, preset frame is carried out to the target frame and continuous N frame
Grade coding.For example: as shown in Figure 3, it is assumed that there are this 5 video frames of F1-F5, if the target frame is F1, F2-F4 with should
Target frame is identical, and the different target frames of F5, then the continuous N frame are as follows: F2-F4, F5 are first and mesh after the target frame
The different video frame of frame is marked, then, then preset frame level is executed to the F1 and F2-F4 and encoded.
Specifically, whether identical as continuous N frame in order to detect the target frame, it can be determined that the target frame and the target frame
Whether next frame is identical, if identical, can continue to judge whether the next frame after the next frame is identical as the target frame,
Until first video frame different from the target frame is found, at this point it is possible to obtain the corresponding repeating frame of the target frame
Quantity, i.e., the quantity of continuous N frame.It is understood that stopping if the target frame is not identical as the next frame of the target frame
Detection, and determine that the next frame of the target frame is different from the target frame, do not meet continuous N frame and target frame after the target frame
Identical condition.For example: referring to Fig. 3, it is assumed that there are this 5 video frames of F1-F5, F1-F4 are identical video frame, if
Whether the target frame is F1, identical as continuous N frame in order to detect the target frame, then first determines whether F1 is identical as F2, is judged
As a result for it is identical when, continue judge whether F1 identical as F3, judging result be it is identical when, it can be determined that F1 whether with F4 phase
Together, and judging result be still it is identical, then continue to judge whether the F1 and F5 identical, judging result be difference, at this point, obtain F1 with
This continuous 3 frame of F2-F4 is identical, and F5 is first video frame different from F1.
It is understood that judgment mode whether identical for any two frame is there are a variety of, for example: can calculate
The similarity of two frames judges whether two frames are identical based on similarity；Alternatively, two frames can be subtracted each other, tied based on subtracting each other
Fruit judges whether two frames are identical.Any one can judge that the whether identical mode of two frames can be applied to the application, tool
Which kind of body uses, and can be set according to the actual situation, the application does not limit this.
Further optionally, to the mode of the quantity statement of the target frame corresponding repeating frame progress frame level, may include:
The quantity of the corresponding repeating frame of the target frame is stated into the mode in frame head, is not limited thereto certainly.Also, it is so-called
Quantity is stated in frame head, i.e., increases new semanteme in frame head, and the new semanteme is for characterizing claim information, and the new semanteme
Binary encoded content can be used.
It should be noted that based on the quantity of the corresponding repeating frame of the target frame is stated the mode in frame head, about
The specific implementation of preset frame level coding is carried out there are a variety of to the target frame and continuous N frame, in order to be laid out it is clear and
Scheme understands, subsequent to carry out in detail about the specific implementation for carrying out preset frame level coding to the target frame and continuous N frame
It introduces.
S102, after the frame level coding that is finished, by first view after the target frame and different from the target frame
Frequency frame, as next target frame to be encoded.
Due to by way of only encoding a frame and carrying out quantity statement to repeating frame simultaneously, ensure that the target frame and continuous
The coding quality of N frame, that is, the every frame for being equal to the target frame and continuous N frame are encoded, and therefore, being finished, the frame level is compiled
After code, after the target frame and it can will be different from first video frame of the target frame, as next target frame to be encoded,
And then return to the step of executing S101.In this way, the identical each group video frame of content can carry out frame level coding in video, thus
Amount of coded data is greatly reduced, code efficiency is improved.
In addition, it is necessary to explanation, for target frame to be encoded, if detecting the next frame and the mesh of the target frame
It is different to mark frame, then block grade coding can be carried out to the target frame；After being finished to the block grade coding of the target frame, by the mesh
The next frame for marking frame as next target frame to be encoded, and then returns and executes S101.
It is emphasized that the specific implementation of the block grade coding mentioned in the present embodiment and in the prior art piece
The mode of grade coding is identical, and the application is without limitation.Illustratively, the process of block grade coding can be with are as follows: for any to be encoded
Data block, the corresponding prediction block of data to be encoded block is obtained from reference frame, then, by data to be encoded block and prediction block phase
Subtract to obtain residual error, to what is obtained after residual error execution DCT (Discrete Cosine Transform, discrete cosine transform) transformation
DCT coefficient matrix is disposably quantified, finally, will quantization obtained DCT coefficient matrix, data to be encoded block and prediction block it
Between motion vector etc. be input in entropy coder and encoded.
A kind of method for video coding provided herein, during being encoded to video, for be encoded
Target frame, if continuous N frame is identical as target frame after detecting target frame to be encoded, to the target frame and continuous N frame
Preset frame level coding is carried out, i.e., block grade coding is carried out to the frame in the target frame and continuous N frame, and corresponding to the target frame
Repeating frame carry out frame level quantity statement；It, will be after the target frame and different from the mesh after the frame level coding that is finished
First video frame for marking frame, as next target frame to be encoded.As it can be seen that by this programme, it is consistent for content continuous
At least two frames only carry out block grade coding to the frame in this at least two frames, while carrying out frame level statement to the quantity of repeating frame,
The block grade coding for repeating frame is avoided, therefore, under the premise of guaranteeing coding quality, the volume in cataloged procedure can be improved
Code efficiency.
Based on the quantity of the corresponding repeating frame of the target frame is stated the mode in frame head, about to the target frame and company
Continuous N frame carries out the specific implementation of preset frame level coding there are a variety of, is lifted below with reference to two kinds of specific implementations
Example explanation.
Optionally, in one implementation, the step of preset frame level coding being carried out to the target frame and continuous N frame,
May include:
For the frame in the target frame and continuous N frame, the first claim information is added in the frame head of the frame, and to addition
The frame after first claim information carries out block grade coding；
Wherein, which is used to state: about the video frame for being added with first claim information, there are N number of
Repeating frame.
In this kind of implementation, which can add any frame in the target frame and continuous N frame
Frame head in.It is understood that first claim information can be binary encoded content, binary encoded content
Represented meaning are as follows: about the video frame for being added with first claim information, there are N number of repeating frames.For the first statement letter
Corresponding specific binary encoded content is ceased, and is applied without limitation.
In a particular application, convenient in order to add, for the frame in the target frame and continuous N frame, in the frame head of the frame
The first claim information of middle addition may include:
The first claim information is added in the frame head of the target frame；Alternatively, adding in the last frame of the continuous N frame
One claim information.
For example, with reference to Fig. 3, it is assumed that there are this 5 video frames of F1-F5, F1-F4 is identical video frame, if the target
Frame is F1, and the target frame is identical as continuous 3 frame, at this point it is possible to increase by the first claim information in the frame head of F1, to complete needle
For the frame level coding of F1 and F2-F4, which shows F1, and there are 3 repeating frames；It is subsequent extensive to repeating frame progress
When multiple, after decoding F1,3 F1 can be increased after F1.For another example, referring to Fig. 3, it is assumed that there are this 5 videos of F1-F5
Frame, F1-F4 are identical video frame, if the target frame is F1, the target frame is identical as continuous 3 frame, at this point it is possible to F4's
Increase by the first claim information in frame head, to complete the frame level coding for being directed to F1 and F2-F4, which shows this
There are 3 repeating frames by F4；It is subsequent when restoring to repeating frame, after decoding obtains F4,3 F4 are added before F4.
Optionally, in another implementation, the described pair of target frame and continuous N frame carry out preset frame level coding
Step may include:
