Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The embodiments described in the following examples do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In this case, the phrase "at least one of the plurality of items" in the present disclosure means that the three parallel cases including "any one of the plurality of items", "a combination of any plurality of the plurality of items", and "the entirety of the plurality of items" are included. For example, "including at least one of a and B" includes the following three cases in parallel: (1) comprises A; (2) comprises B; and (3) comprises A and B. For another example, "at least one of the first step and the second step is performed", which means that the following three cases are juxtaposed: (1) executing the step one; (2) executing the step two; and (3) executing the step one and the step two.
In the related art, the output (lead-out) position of the video is selected mainly by setting a white list. The tester tests the high-grade video output (export) of a plurality of types of equipment on line, and the developer configures the types of the equipment meeting the high-grade video output (export) condition into a white list. When the output (derivation) gear of the video is selected, whether the current equipment model is contained in the white list or not is judged, and the output (derivation) gear of the video is selected according to the white list. The related art has two main problems: firstly, the development cost is high and the flexibility is not enough. The addition of the white list depends on the offline test result of a tester, the test of the tester is difficult to cover all equipment models, and the tester is required to test new equipment models whenever the new equipment models appear. Secondly, real-time data is not combined, the actual performance of the current equipment cannot be accurately reflected by setting a model white list, and poor experience of a user can be caused after unreasonable gears are selected by mistake. The performance of the same model and different loss conditions of the equipment can be different.
Hereinafter, a method and apparatus for outputting video according to an exemplary embodiment of the present disclosure will be described in detail with reference to fig. 1 to 5. The method and the device for outputting the video according to the exemplary embodiments of the present disclosure are adapted to complete an output (export) scene after video editing, and before video output (export), determine whether to output (export) the video as a high-end video by combining at least one of model basic capability (e.g., resolution, memory of the electronic device), video resolution, real-time performance data, and configured high-end video threshold. It should be understood that for high-grade understanding, the definition of high-grade and medium-grade may be different due to different models and networks in different country and region. In an exemplary embodiment of the present disclosure, a code rate of 5Mbps, at a resolution of 720p, at mid-range; the high-end code rate is 1080p and 8Mbps.
Fig. 1 illustrates a flowchart of a method for outputting video according to an exemplary embodiment of the present disclosure.
Referring to fig. 1, in step S101, an output parameter gear of a video is determined based on at least one of model capability check information of an electronic device, a video resolution, and real-time performance data of the electronic device when previewing the video.
In an exemplary embodiment of the present disclosure, an output parameter gear of a video may be used to determine a resolution of the output video.
In an exemplary embodiment of the present disclosure, when an output parameter gear of a video is determined based on at least one of model capability check information, video resolution, and real-time performance data of the electronic device when the video is previewed, the model capability check information of the electronic device may be first acquired, the output parameter gear of the video may be determined based on the model capability check information of the electronic device, and then the output parameter gear of the video may be determined as a preset gear when the output parameter gear of the video determined based on the model capability check information of the electronic device is the preset gear. In an exemplary embodiment of the present disclosure, the model capability checking information may include at least one of a resolution and a memory of the electronic device. It should be understood that the model capability check information may also include other relevant parameters or data, which the present disclosure does not limit. For example, if the resolution of the electronic device reaches above 720p and the memory reaches above 3.8g, it is determined that the output parameter gear of the video is not the preset gear, otherwise it is determined that the output parameter gear of the video is the preset gear. Here, if the output parameter gear of the video is classified into two or more gears, the preset gear may be a designated or preset gear among the two or more gears.
In an exemplary embodiment of the disclosure, when the output parameter gear of the video determined based on the model capability check information of the electronic device is not the preset gear, the video preview may be started first, the video resolution is obtained, the output parameter gear of the video is determined based on the video resolution, and then when the output parameter gear of the video determined based on the video resolution is the preset gear, the output parameter gear of the video is determined as the preset gear. Before entering the publication page, a video preview page exists on a video client of a general electronic device, so that a user can see a video preview effect. Video clients of most electronic devices can also edit functions on the video preview page support. For example, if the resolution of the video itself is high (e.g., up to 720p or more), the determined output parameter gear of the video is not a preset gear; the resolution of the video itself is low (e.g., below 720 p), and the determined output parameter level of the video is a preset level. Because if the resolution of the video itself is low (e.g., lower than 720 p), it is not necessary to stretch the original video to a higher (e.g., higher than 720 p) resolution. This does not yield a benefit of sharpness, but only increases the video size unnecessarily.
In an exemplary embodiment of the present disclosure, when the output parameter gear of the video determined based on the video resolution is not the preset gear, the real-time performance data of the electronic device during the video preview may be first obtained, and the output parameter gear of the video may be determined based on the real-time performance data, and then when the output parameter gear of the video determined based on the real-time performance data is the preset gear, the output parameter gear of the video may be determined as the preset gear; and when the output parameter gear of the video determined based on the real-time performance data is not the preset gear, determining the output parameter gear of the video as the output parameter gear of the video determined based on the real-time performance data. In an exemplary embodiment of the present disclosure, the real-time performance data may include at least one of cpu utilization, preview frame rate, and katton rate. It should be understood that the real-time performance data may also include other relevant parameters or data, which the present disclosure does not limit. For example, if the real-time Cpu utilization rate of the electronic device is 48%, the preview frame rate is 25 frames/second, and the katon rate (katon times per second) is 0.1, it is determined that the output parameter gear of the video is not the preset gear, otherwise it is determined that the output parameter gear of the video is the preset gear.
In an exemplary embodiment of the present disclosure, the output parameter gear of the video may be classified into at least a high gear and a normal gear. Here, the high-end is an output parameter level of a video having a resolution of an output video not lower than a preset resolution, and the normal-end is an output parameter level of a video having a resolution of an output video lower than the preset resolution. Here, the preset resolution may be, for example, but not limited to, 480p, 720p, 1080p, and the like.
In an exemplary embodiment of the present disclosure, when an output parameter gear of a video is determined based on at least one of model capability check information, video resolution, and real-time performance data of the electronic device when the video is previewed, the model capability check information of the electronic device may be first acquired, and the output parameter gear of the video may be determined based on the model capability check information of the electronic device, and then when the output parameter gear of the video determined based on the model capability check information of the electronic device is a normal gear, the output parameter gear of the video may be determined as the normal gear.
In an exemplary embodiment of the present disclosure, when the output parameter gear of the video determined based on the model capability check information of the electronic device is the top gear, the video preview may be first started and the video resolution is acquired, the output parameter gear of the video is determined based on the video resolution, and then the output parameter gear of the video is determined as the normal gear when the output parameter gear of the video determined based on the video resolution is the normal gear.
In an exemplary embodiment of the present disclosure, when the output parameter gear of the video determined based on the video resolution is a high gear, the real-time performance data of the electronic device while previewing the video may be first acquired, and the output parameter gear of the video may be determined based on the real-time performance data, and then when the output parameter gear of the video determined based on the real-time performance data is a normal gear, the output parameter gear of the video may be determined as a normal gear; and when the output parameter gear of the video determined based on the real-time performance data is a high gear, determining the output parameter gear of the video as a high gear.
In an exemplary embodiment of the present disclosure, when acquiring the real-time performance data of the electronic device when previewing a video, the real-time performance data of the electronic device when previewing the video may be acquired first, the acquired real-time performance data may be normalized, and then the normalized real-time performance data may be used as the real-time performance data of the electronic device when previewing the video.
Since the cpu utilization rate is large in the whole preview process, for example, when a preview page is just entered and a preview page is just pushed out, the cpu utilization rate is high because other modules may consume the cpu besides the video preview module. Therefore, for example, the cpu utilization rate may be calculated once per second, and the 50-quantile data in the preview process is finally obtained, thereby obtaining the normalized cpu utilization rate. And taking the average value of the preview frame rates in the whole preview process as the preview frame rate after the normalization processing. In the process of adding some special effects, performance is additionally consumed when the special effects are initialized, and the video is stuck, so that the data needs to be checked when the stuck rate data is processed. For example, the stuck rate may be calculated once per second, the 50 quantiles are calculated first, then the special data far greater than the 50 quantiles (in the current calculation method, a value 3 times the 50 quantiles is calculated as a special data comparison threshold, and the special data greater than the threshold is considered as the special data) is checked, and then the 50 quantiles are calculated for the whole body after the special data is checked, so that the normalized stuck rate is obtained.
In step S102, the video is output based on the determined output parameter steps of the video.
In an exemplary embodiment of the present disclosure, as an example, when the output parameter gear of the video is classified into at least a high gear and a normal gear, if the determined output parameter gear of the video is the high gear, the video having a high gear resolution (for example, but not limited to, 720 p) is output (derived), and if the determined output parameter gear of the video is the normal gear, the video having a normal gear resolution is output (derived).
In an exemplary embodiment of the present disclosure, as an example, when the output parameter gear of the video is classified into first gear to fifth gear, if the output parameter gear of the determined video is the first gear, the video having the first gear resolution (for example, but not limited to, 240 p) is output (derived), if the output parameter gear of the determined video is the second gear, the video having the second gear resolution (for example, but not limited to, 360 p) is output (derived), if the output parameter gear of the determined video is the third gear, the video having the third gear resolution (for example, but not limited to, 720 p) is output (derived), if the output parameter gear of the determined video is the fourth gear, the video having the fourth gear resolution (for example, but not limited to, 1080 p) is output (derived), if the output parameter gear of the determined video is the fifth gear, the video having the fifth gear resolution (for example, but not limited to, 4K) is output (derived).
Fig. 2 illustrates a flowchart of a method for outputting a video according to another exemplary embodiment of the present disclosure.
Referring to fig. 2, in step S201, model capability check information of an electronic device is obtained, and an output parameter gear of a video is determined based on the model capability check information of the electronic device.
In an exemplary embodiment of the present disclosure, the output parameter gear of the video is classified into at least a high gear and a normal gear. Here, the high-end is an output parameter level of a video in which the resolution of the output video is not lower than a preset resolution, and the normal-end is an output parameter level of a video in which the resolution of the output video is lower than the preset resolution. Here, the preset resolution may be, for example, but not limited to, 480p, 720p, 1080p, and the like.
When the output parameter gear of the video determined based on the model capability check information of the electronic device is the normal gear, in step S202, the output parameter gear of the video is determined to be the normal gear, and the normal gear video is output (derived).
In step S203, when the output parameter gear of the video determined based on the model capability check information of the electronic device is high, video preview is started, and real-time performance data of the electronic device in previewing the video is acquired.
In step S204, the video resolution is acquired, and the output parameter gear of the video is determined based on the video resolution.
When the output parameter gear of the video determined based on the video resolution is the normal gear, step S202 is performed, the output parameter gear of the video is determined to be the normal gear, and the normal gear video is output (derived).
In step S205, when the output parameter gear of the video determined based on the video resolution is the high gear, the normalization processing is performed on the acquired real-time performance data.
In step S206, an output parameter gear of the video is determined based on the real-time performance data.
When the output parameter gear of the video determined based on the real-time performance data is the normal gear, step S202 is performed to determine the output parameter gear of the video as the normal gear, and output (derive) the normal gear video.
When the output parameter notch of the video determined based on the real-time performance data is the high notch, the output parameter notch of the video is determined to be the high notch and the high notch video is output (derived) in step S207.
