Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is described.
Referring to Fig. 1, Fig. 1 show a kind of flow signal of live video stream generating method provided in an embodiment of the present invention Figure, may comprise steps of：
S101, server-side obtain the state parameter of client, and state parameter includes：The corresponding calculation of special video effect to be added The current device performance parameters of equipment where method complexity and client.
Wherein, special video effect to be added can be that one kind can also be a variety of, and algorithm complexity is one and is used to represent The numerical value of the number of the required operand of special video effect to be added realized.Obtain the corresponding algorithm of special video effect to be added Complexity can be the video to be added spy for receiving the algorithm complexity that client is sent or receiving client transmission The information of effect, and further according to the information determining algorithms complexity.Illustratively, what server-side reception client was sent waits to add Add the code name of special video effect, determine that the code name is corresponding using default code name-algorithm complexity correspondence according to the code name Algorithm complexity.Similarly, can receive the visitor that the device performance parameters that client is sent or reception client are sent The current relevant information of equipment where the end of family, device performance parameters are determined according to the information by server-side.
S102 according to the state parameter, using default execution decision-making device, judges whether to add video spy by server-side Effect, obtains judging result, which is that the state parameter based on multiple sample clients creates, sample visitor Whether family end is known by server-side addition special video effect；
In the present embodiment, judge whether a sample client is by by sample visitor by server-side addition special video effect Family end adds special video effect and by the video stream added with special video effect to server-side, calculates and adds since sample client Special video effect is added to receive the used time of the video flowing added with special video effect to server-side.If the used time is more than default acceptable Delay threshold, then it is assumed that the sample client adds special video effect by server-side.If the used time is subjected to prolonging no more than default When threshold value, then it is assumed that the sample client does not add special video effect by server-side.
It is understood that perform decision-making device can regard as the state parameter of a client and the client whether by Server-side adds the mapping relations of special video effect.In the present embodiment, which can be realized using Logic Regression Models, Can also be realized using neural network model or other models in other realization methods.
Can work as equipment where the corresponding algorithm complexity of special video effect to be added and client in the present embodiment Preceding device performance parameters, input perform decision-making device, perform decision-making device according to default mapping ruler, export corresponding mapping Value, if the size of the mapping value meet it is default by the corresponding characteristic condition of server-side addition special video effect, it is determined that by taking Be engaged in end addition special video effect, if alternatively, the size of the mapping value meet it is default by client addition special video effect it is corresponding Characteristic condition, it is determined that special video effect is added by server-side.
S103 will determine that result is sent to client.
S104, if it is judged that add the special video effect by server-side, receive that client sends is not added with this and regards The pending video flowing of frequency special efficacy.
S105 adds the special video effect in pending video flowing, obtains live video stream.
In the present embodiment, after pending decoding video stream, corresponding special video effect processing is carried out, then is obtained after recompiling To live video stream.It is understood that the performance of equipment where the performance of equipment is better than client where server-side, therefore into When the identical special video effect of row is handled, the server-side used time will be shorter than the client used time.And for
The embodiment is selected, it can be by default execution decision-making device, according to corresponding including special video effect to be added The state parameter of client including the current device performance parameters of equipment where algorithm complexity and client, it is determined whether by Server-side adds special video effect, transfers to performance strong special video effect excessively complicated for the performance of equipment where client Big server-side processing.It avoids since addition special video effect causes live streaming to be delayed the problem of larger.
Referring to Fig. 2, Fig. 2 show another flow signal of live video stream generating method provided in an embodiment of the present invention Figure, may comprise steps of：
S201, client send the state parameter of client, shape to server-side after addition special video effect instruction is received State parameter can include：The current device performance parameters of equipment where the corresponding algorithm complexity of special video effect and client.
In an optional implementation manner, device performance parameters can include：
Electrical parameter for the ability parameter for representing the operational capability of CPU and/or for representing remaining capacity.
It is understood that device performance parameters can include ability parameter and electrical parameter simultaneously, energy can also be included Force parameter is without including electrical parameter, alternatively, including electrical parameter without including ability parameter.
Wherein, ability parameter can be determined according to the CPU numbers per second that can carry out floating point arithmetic or root It is obtained according to the default operational capability scoring of the model of CPU and the utilization rate weighted calculation of current CPU.Illustratively, a visitor The model A types of the CPU of family end equipment are a kind of stronger CPU of performance, and corresponding operational capability scoring is 0.9, currently The utilization rate of CPU is 10%, then the ability parameter of the client is 0.9 × (1-10%)=0.81.It is understood that CPU Operational capability it is stronger, it is also shorter to complete the addition required time of special video effect, therefore client more need not be by servicing End addition special video effect.
Electrical parameter can be the percentage of remaining capacity or the scope according to residing for the percentage of remaining capacity A definite numerical value.Illustratively, when residual power percentage is higher than 20%, electrical parameter 1, when remaining capacity percentage During than being not higher than 20%, electrical parameter 0.It is understood that adding special video effect by client, can be set to client place It is standby to bring additional electric quantity consumption, therefore when equipment remaining capacity where client is relatively low, set for extending where client Standby usage time is considered, and can add special video effect by server-side.
In an optional implementation manner, state parameter can also include：
For representing the communication state parameters of the communications status between server-side and client.
Wherein, communication state parameters can be according to the determine or root that is delayed between server-side and client Being determined according to network specifics used in client (such as wifi, wired, 2G etc.), illustratively, when client is connected using wifi Can will communication state parameters be at this time 0.8, when client uses since the network speed of wifi is usually than very fast when accessing network Can will communication state parameters be at this time 0.2 since the network speed of 2G is usually relatively slow when 2G is connected into the network.
It is understood that when the communications status between server-side and client is poor, between client and server-side Message transmission rate it is slower, larger delay can be brought to net cast, can video video be added by server-side at this time, with Shorten the time of addition special video effect consumption, make up the live streaming delay brought since communications status is poor.
S202, server-side receive the state parameter of client.
S203, server-side is using state parameter as mode input, using Logic Regression Models, calculates that client is corresponding to reflect Penetrate value.
Specifically, in the present embodiment, Logic Regression Models as follows can be utilized, calculate the corresponding mapping of client Value：
Wherein, θiFor i-th of default model parameter of the Logic Regression Models, i is a positive integer, hθ(x) it is not by taking The confidence level of business end addition special video effect, xiFor i-th of mode input, m is a default threshold value, and n is of mode input Number.
Wherein, whether model parameter is predetermined, can be based on known by the multiple of server-side addition special video effect What the state parameter of sample client created, that is, build default execution decision-making device.
Specifically, in the present embodiment, the initial value of each model parameter is rule of thumb artificially set first.
Then, using the state parameter of each sample client as mode input, each sample client is obtained Mapping value.According to the mapping value of each sample client, the score of currently used model parameter is calculated according to the following formula：
Wherein P be "current" model parameter score, k be sample client quantity, fiTo be based on "current" model parameter meter The mapping value of i-th obtained of sample client, riRepresent whether i-th sample client by server-side adds special video effect Artificial judgment as a result, if i-th of sample client adds special video effect, r by server-sideiFor 0, on the contrary then riFor 1.
Finally, constantly model parameter is adjusted, and calculates the score of the model parameter after adjustment, until after adjustment The score of model parameter is higher than predetermined threshold value.
In an optional implementation manner, server-side can be using the load factor of state parameter and server device as mould Type inputs, and using default Logic Regression Models, calculates the corresponding mapping value of client.
The model parameter of Logic Regression Models can based on it is known whether by server-side addition special video effect multiple samples What the load factor of the state parameter of client and corresponding sample server-side determined.It is understood that work as server device When load factor is higher, in order to avoid further increasing load pressure to server device, in allowed limits as far as possible by client End addition special video effect.
