Referring to Fig. 4, another embodiment of the application provides a kind of method for processing video frequency, electronic equipment can be applied to,The method for processing video frequency may include:
Step S310: when carrying out video playing, detection plays the source of video.
Step S320: judge whether the source for playing video is local file.
In the embodiment of the present application, step S310 and step S320 can be refering to the content of above-described embodiment, herein notIt repeats again.
Step S330: when source is local file, the video parameter values for playing video, the video parameter are obtainedValue includes at least one of code rate, resolution ratio and frame per second.
In the embodiment of the present application, when the source for judging to play video is local file, that is, the source of video is playedWhen local file, the system resource that the task due to playing video occupies is less, can carry out display increasing to video is playedStrength reason causes to play video cardton without keeping processor burden excessive.
Further, when determining that playing the source of video is not network, display enhancing processing is carried out to video is playedWhen, the display enhancing for playing the optimization operation that video carries out all Optimal Parameters can be handled, or carry out part optimization ginsengThe display enhancing processing of several optimization operations.Wherein, all Optimal Parameters refer to all optimizations ginseng being arranged in above-mentioned HQV moduleNumber.
Specifically, the parameter value for playing video can be obtained when the source for playing video is local file, withAccording to the parameter value for playing video, determines and the display enhancing for playing the optimization operation that video carries out all Optimal Parameters is handled,Or carry out the display enhancing processing of the optimization operation of part Optimal Parameters.Wherein, the parameter value for playing video includes code rate, dividesAt least one of resolution and frame per second.The data bits of unit time transmission when the code rate of video refers to data transmission, videoThe quality of code rate and video is directly proportional, but file size is also directly proportional with code rate.Resolution ratio is for measuring data in imageAmount number a parameter, resolution ratio determines the fine degree of bitmap images details, it is generally the case that the resolution ratio of imageHigher, the pixel for being included is more, and image is more clear, meanwhile, it also will increase the memory space of file occupancy.Frame per second isFor measuring the measurement of display frame number, i.e., frame number per second, when frame per second is higher, the corresponding picture of video is more, therefore video textPart is bigger.When obtaining video parameter values, the Video attribute information entrained by video file can be identified and be obtained, it is specific to obtainThe mode of video parameter values can be not as restriction.
It should be understood that above-mentioned video parameter values are bigger, corresponding video quality is better, and the visual effect played out is better,But since corresponding file is larger, occupied resource is also more when video playing.It therefore, can be to the video for playing videoParameter is detected, to carry out display enhancing processing to video is played according to video parameter.
Step S340: judge whether the video parameter values are lower than given threshold.
In the embodiment of the present application, after getting the video parameter values for playing video, then it may determine that video parameterValue whether given threshold.It should be understood that when video parameter values include many kinds of parameters value, then it can be by every kind of parameter value and itsCorresponding given threshold is compared, to judge whether given threshold is lower than given threshold.For example, video parameter values include code rateAnd when resolution ratio, then judge whether the code rate got is lower than code rate threshold value, and judges whether the resolution ratio got is lowIn resolution threshold.Wherein, the value that the size of resource is occupied when above-mentioned given threshold can be set as distinguishing its broadcasting, whenVideo parameter values be lower than given threshold, then its play when occupy resource it is smaller, when video parameter values be higher than given threshold when, then itsIt is more to occupy resource.Specific given threshold in the embodiment of the present application can be not as restriction, can be according to video parameterType determines.
Step S350: if shown according to all Optimal Parameters to the broadcasting video lower than the given thresholdEnhancing processing.
In the embodiment of the present application, when judge in step S350 the video parameter values for playing video lower than given threshold,It is less then to play video occupied resource when playing, it at this time then can be according to above-mentioned all Optimal Parameters, to broadcasting videoCarry out display enhancing processing.When video parameter values include a variety of, can be when to be below its corresponding for every kind of video parameter valuesWhen given threshold, according to all Optimal Parameters, display enhancing processing is carried out to video is played.
That is, can be chosen when being lower than given threshold from the video parameter values of the broadcasting video of local fileAll Optimal Parameters in above-mentioned HQV algoritic module are joined as the optimization for carrying out display enhancing processing to broadcasting videoNumber.Then, according to all Optimal Parameters, display enhancing processing, that is, the video played, by decoded view are carried out to video is playedFrequency is intercepted according to as image data to be rendered by above-mentioned HQV algoritic module, and HQV algoritic module is by above-mentioned figure to be renderedAs data are stored to off screen Render Buffer, own to the image of the multiple image data in off screen Render BufferOptimal Parameters it is corresponding optimization operation display enhancing processing and then be transmitted to SurfaceFlinger carry out rendering and afterContinuous optimization operation on the screen, so that the video image of display achievees the effect that super clear visual effect.For example, when in HQV moduleAll Optimal Parameters include exposure enhancing, denoising, edge sharpening, contrast increases and the increased Optimal Parameters of saturation degree,Then image data degree of being exposed enhancing to be rendered, denoising, edge sharpening, contrast are increased and saturation degree is increased excellentChange operation, then carries out follow-up play.
By determining that the source for playing video is not network and plays the video parameter values of video lower than given thresholdWhen, the display enhancing for playing the whole Optimal Parameters of video progress is handled, does not come source network, and video due to playing videoParameter value is lower, therefore the resource occupied excessively will not keep processor burden excessive, makes to play video with super clear visual effectMeanwhile guaranteeing the fluency of video playing.
Step S360: if being not less than the given threshold, according to the part Optimal Parameters in all Optimal Parameters, to instituteIt states broadcasting video and carries out display enhancing processing.
In the embodiment of the present application, when the video parameter values for judging broadcasting video in step S350 are not less than setting thresholdValue, then playing video, occupied resource may be more when playing, at this time then can be according to above-mentioned all Optimal Parameters middle partsDivide Optimal Parameters, carries out display enhancing processing to video is played.When video parameter values include a variety of, can be ought be wherein anyWhen a kind of video parameter values are not less than its corresponding given threshold, according to part Optimal Parameters in all Optimal Parameters, to broadcastingVideo carries out display enhancing processing.
That is, when being not less than given threshold from the video parameter values of the broadcasting video of local file, it is to be renderedImage data, can carry out part Optimal Parameters it is corresponding optimization operation display enhancing processing and then be transmitted toSurfaceFlinger carries out rendering and subsequent optimization operation on the screen, so that the video image of display reaches high visual effectEffect.For example, when the part Optimal Parameters of selection include contrast increase and saturation degree increase, then to figure to be renderedAs the increase of data degree of comparing and the increased optimization operation of saturation degree, follow-up play is then carried out.
In the embodiment of the present application, from all Optimal Parameters, when selected part Optimal Parameters are as objective optimization parameter,It can be preset part Optimal Parameters, as the objective optimization parameter for carrying out display enhancing processing, this is presetPart Optimal Parameters are the part Optimal Parameters in above-mentioned all Optimal Parameters.That is, when need to play video intoWhen the display of row part Optimal Parameters enhances processing, then the part Optimal Parameters of above-mentioned setting can be directly utilized, are regarded to playingFrequency carries out display enhancing processing.Certainly, from all Optimal Parameters, when selected part Optimal Parameters are as objective optimization parameter,It is also possible to the rule by setting, Optimal Parameters is chosen, such as the rule of setting can be working as according to processorPreceding load factor obtains its corresponding Optimal Parameters, is also possible to the optimization priority according to setting, chooses the optimization of setting quantityParameter.Certainly, the rule specifically set in the embodiment of the present application can be not as restriction.
By determine that the source for playing video is not network but when video parameter is higher, to playing video carry out portionThe display enhancing processing of point Optimal Parameters does not carry out source network due to playing video, and according only to part Optimal Parameters to broadcastingIt puts video and carries out display enhancing processing, therefore the resource occupied excessively will not keep processor burden excessive, so as to so as to broadcastWhile video is put with higher visual effect, guarantee the fluency of video playing.
Step S370: when source is not local file, judge whether the broadcasting video obtains in real time from networkVideo file.
In the present embodiment, step S370 can be refering to the content of above-described embodiment, and details are not described herein.
Step S380: when the broadcasting video is the video file obtained in real time from network, according to all optimizationsPart Optimal Parameters in parameter carry out display enhancing processing to the broadcasting video.
In the embodiment of the present application, when judge in step S380 play video whether be the video obtained in real time from networkWhen file, i.e. broadcasting video is when deriving from network in real time, then can according to the part Optimal Parameters in above-mentioned all Optimal Parameters,Display enhancing processing is carried out to video is played.It should be understood that when electronic equipment is when playing the video for deriving from network in real time,The occupied system resource of video playing is more, and for opposite broadcasting local video, processor burden is larger, therefore only to broadcastingVideo carries out the display enhancing processing of optimization operation corresponding to part display enhancing parameter, it is possible to prevente effectively from processor is negativeCarry on a shoulder pole Caton that is excessive, and generating video playing.
Certainly, in the embodiment of the present application, when judging that playing video is the video file obtained in real time from network,Display enhancing processing can not be carried out to video is played, that is to say, that as the concomitant regimen of above-mentioned steps S380, regard when playingVideo file of the frequency to obtain in real time from network constantly, is forbidden carrying out broadcasting video display enhancing processing, i.e., directly will broadcastingVideo plays out, and to reduce the resource that video playing occupies processor, avoids processor burden excessive and generates video playingWhen Caton.
