The execution main body of the method for acquiring the loading duration provided by the present disclosure may be the apparatus for acquiring the loading duration provided by the present disclosure, and the apparatus for acquiring the loading duration may be integrated in a mobile terminal device (e.g., a smart phone, a tablet computer, etc.), a notebook computer or a fixed terminal (e.g., a desktop computer, etc.), and the apparatus for acquiring the loading duration may be implemented by hardware and/or software.
Fig. 1 is a flowchart illustrating a method for acquiring a loading duration according to an exemplary embodiment. As shown in the figure, the method for acquiring the loading duration may include: contents shown in step S11 to step S14.
In step S11, at the initial time when the first scene is switched to the second scene, a screen recording operation is performed on the current interface.
In step S12, when the loading of the second scene is finished, the screen recording operation on the current interface is finished, so as to obtain a screen recording video.
In the embodiment of the disclosure, when scene switching is detected, that is, at the initial time when the first scene is switched to the second scene, screen recording operation is performed on the current interface, and when it is detected that loading of the second scene is finished, screen recording is finished to obtain a screen recording video for subsequent use.
In step S13, a key frame in the screen recording video is acquired.
Where the key frame carries a timestamp.
In step S14, the loading duration for switching the first scene to the second scene is obtained according to the timestamp of the key frame.
In the embodiment of the present disclosure, the loading duration for switching the first scene to the second scene is obtained according to the timestamp carried by the key frame acquired from the screen recording video.
Therefore, in the embodiment of the present disclosure, at the initial time when the first scene is switched to the second scene, the screen recording operation is performed on the current interface, when the loading of the second scene is finished, the screen recording operation on the current interface is finished to obtain the screen recording video, then the key frame in the screen recording video is obtained, and finally, according to the timestamp of the key frame, the loading duration for switching the first scene to the second scene is obtained. The key frame carrying the time stamp is obtained by utilizing the change of the screen content, so that the loading time length for switching from the first scene to the second scene can be more accurately obtained.

As shown, acquiring key frames in a screen-recorded video may include: the contents shown in step S131 to step S132.
In step S131, a video frame splitting process is performed on the screen recording video to obtain a plurality of video frames.
Wherein each video frame carries a timestamp.
In the embodiments of the present disclosure, there are many methods for video frame splitting, for example: the video frame splitting is performed by using Python + OpenCV (open source computer vision library), or by using matlab software, and the video frame splitting can also be performed by using other software. After frame dropping, each video frame carries a timestamp.
In step S132, a key frame of the plurality of video frames is extracted according to the inter-frame difference of the video frames.
Wherein, the number of the key frames is 2.
In the embodiment of the present disclosure, when a video is split into frames, the difference degree between the current video frame and the previous video frame is compared, for example, the difference degree may be obtained through an absdiff function in OpenCV, and the difference degree corresponds to the positions of the current video frame and the current video frame in the screen recording video, and finally, the two video frames with the largest difference degree values of all the video frames are determined as the most key frames.

In step S1321, an inter-frame difference of each of the plurality of videos from a previous video frame is calculated.
In step S1322, the inter-frame differences are sorted to obtain a sequence of inter-frame differences sorted from large to small.
In step S1323, two inter-frame differences ordered as first and second in the sequence of inter-frame differences are acquired.
In step S1324, the video frame corresponding to the first and second inter-frame differences is used as a key frame.
In the embodiment of the present disclosure, two video frames with the largest inter-frame difference among all the video frames may be obtained in a sorting manner, and the sorting manner may be from large to small, or from small to large; two video frames with the largest interframe difference in all videos can be obtained in a curve distribution diagram mode, namely, a timestamp of each video frame is used as an abscissa of the curve distribution diagram, the interframe difference of each video frame is used as an ordinate of the curve distribution diagram, two points with the largest ordinate can be obtained, and two corresponding video frames are used as key frames, namely the key frames for starting and stopping scene change; other manners may also be adopted to obtain the key frame, which are not always listed in the embodiments of the present disclosure.
It should be noted that, when selecting a key frame, a preset value is set between key frames to avoid an excessive inter-frame difference caused by some interference factors, that is, when selecting a certain video frame as a key frame, the selection of the next key frame can only be selected from the video frames after the preset number. For example, the preset value is 20 frames, and other frame numbers may also be adopted, which is not limited in the embodiment of the present disclosure.
In a possible implementation manner of the present disclosure, obtaining, according to a timestamp of a key frame, a loading duration used for switching a first scene to a second scene may specifically include: the contents shown in step S141 to step S142.
In step S141, a time stamp of the key frame in the screen-recorded video is acquired.
In step S142, a difference between the timestamps corresponding to the key frames is calculated as a loading duration for switching the first scene to the second scene.
In the embodiment of the present disclosure, the key frames are determined through the above embodiment, and then the time difference between two key frames is calculated according to the timestamp carried by the key frames, and is used as the loading duration for switching the first scene to the second scene. The loading duration when the two scenes are switched can be accurately obtained by using the timestamp of the key frame, multiple tests are not needed, and the loading duration when the two scenes are switched can be accurately obtained only by extracting the key frame once.
