The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The video response detection method provided by the embodiment of the present invention can be applied to the terminal shown in fig. 1, and the terminal 100 is preferably a mobile terminal. As shown in fig. 1, the terminal 100 includes a processor, a nonvolatile storage medium, an internal memory, a network interface, and a display screen, which are connected through a system bus. The processor has a calculation function and a function of controlling the operation of the terminal, and is configured to execute a video response speed detection method. The non-volatile storage medium includes at least one of a magnetic storage medium, an optical storage medium, and a flash memory type storage medium, and the non-volatile storage medium stores an operating system and a video response speed detection system. The video response speed detection system is used for realizing a video response speed detection method for a terminal player. The network interface is for connecting to a server, for communicating with the server, and for receiving resources from a network.
As shown in fig. 2, in an embodiment, a video response speed detection method is provided, which can be applied to the terminal 100 shown in fig. 1, and specifically includes the following steps.
Generally, the video operation instruction includes an instruction to start playing a video or an instruction to move a progress bar. The current video refers to a video played by a browser player of the terminal or other video players.
And step 203, recording the current system time corresponding to the video operation instruction.
The current system time corresponding to the video operation instruction refers to the time for sending the video operation instruction. The current system time when the video operation instruction is obtained is automatically recorded and used as the sending time of the video operation instruction. Specifically, when the video operation instruction is an instruction for starting playing a video, recording the time for clicking a play start button of the player as the current system time corresponding to the video operation instruction; and when the video operation instruction is an instruction of moving the progress bar, recording the operation time of the moving progress bar as the current system time corresponding to the video operation instruction.
Preferably, the starting of the screenshot function is carried out at the same time of acquiring the video operation instruction of the current video. In specific implementation, the starting screenshot function may be before or after the operation instruction of the current video is obtained, and if the starting screenshot function is after the operation instruction of the video is obtained, it is ensured that the starting screenshot function is before a key frame corresponding to the operation instruction of the video appears, so as to ensure that the screenshot when the key frame corresponding to the operation instruction of the video appears can be captured.
By starting the screenshots, a certain number of screenshots are continuously captured at a preset screenshot frequency, and the obtained screenshots are stored according to a preset format respectively. The speed of the screen capture can be adjusted by changing a preset screen capture frequency, which may be the screen capture frequency required to be set after the screen capture function is started, for example, when the screen capture frequency is set to 50 milliseconds, the number of screen captures obtained in one second is 20; when the screen capture frequency is set to 40 milliseconds, the number of screen captures obtained in one second is 25. The preset format refers to a name format or a picture format when the screen capture is stored, and the system time corresponding to the respective screen capture can be conveniently acquired after the screen capture is stored through the specific name format or picture format.
And step 207, acquiring a key frame of the current video corresponding to the video operation instruction.
The key frame corresponding to the video operation instruction refers to a picture frame pointed to by the video operation instruction. For example, when the video operation instruction is an instruction to start playing a video, the picture frame indicated by the instruction to start playing the video is the first frame of the current video, which appears after the start playing button is clicked, that is, the key frame corresponding to the instruction to start playing the video is the first frame; when the video operation instruction is an instruction to move the progress bar, the picture frame indicated by the instruction to move the progress bar is a picture frame played by the time node of the current video where the progress bar is moved, specifically, if the progress bar moves to 00 of the current video: at 20:10, the picture frame played by the time node of the current video where the progress bar is moved is the picture frame of the current video at the position of 00: the picture frame played at 20:10, that is, the key frame corresponding to the instruction to move the progress bar is the picture frame played by the time node where the progress bar is moved.
Acquiring the key frame of the current video can be realized by calling a multimedia video processing tool. The multimedia video processing tool is a set of open source computer programs that can be used to record, convert digital audio, video, and convert them into streams. Invoking a multimedia video processing tool may also be accomplished by invoking an existing multimedia video processing tool Application Programming Interface (API) or function (function) to add functionality to the multimedia video processing tool. Any desired keyframes of the current video can be obtained by the multimedia video processing tool.
And taking the key frame corresponding to the video operation instruction as a reference object, respectively comparing the similarity of the screenshot obtained in the step 205 with the key frame, and searching whether the same screenshot as the key frame exists or a first screenshot with the highest similarity to the key frame from a picture library, wherein the same screenshot or the first screenshot with the highest similarity is a target screenshot corresponding to the key frame. Generally, the screen shot with the similarity of more than 90% with the key frame can be used as the target screen shot meeting the search requirement. The similarity comparison of the searched picture library can be realized by calling a cross-platform computer vision library, namely, the function of increasing the image processing of the cross-platform computer vision library is realized by calling a program programming interface of the cross-platform computer vision library. Since the screen shot is obtained by capturing the terminal screen at the preset screen capture frequency, there may be a case that the screen shot same as the key frame appears between two adjacent captured screen shots, and therefore, the first screen shot with the highest similarity to the key frame may be used as the target screen shot corresponding to the key frame. When a plurality of target screenshots with similarity meeting the requirement exist, the first screenshot refers to the target screenshot with relatively earlier system time corresponding to the screenshot.
And after the target screen capture corresponding to the key frame is found, acquiring the system time when the target screen capture is correspondingly captured, and calculating the time difference between the system time corresponding to the target screen capture and the current system time corresponding to the video operation instruction to be used as the response time of the current video.
In this embodiment, a current video is operated, a current system time when a corresponding operation is sent is recorded, a plurality of screenshots are captured at a preset frequency by starting a screenshot function, and a target screenshot corresponding to a picture frame which is pointed to by the corresponding operation is determined from the screenshots, so that a time difference between the target screenshot and the current system time can be calculated, that is, a response time from sending to finishing of the video from the corresponding operation is detected, and whether a video response speed meets a requirement is judged. The screen capture corresponding to the operation instruction and the current system time corresponding to the operation instruction are obtained automatically, people do not need to participate in the detection process, labor cost is saved, and the accuracy is better.
As shown in fig. 3, in an embodiment, in step 201, the step of obtaining the video operation instruction of the current video includes: step 2015, obtaining a video operation instruction for starting playing by clicking.
By respectively acquiring the video operation instruction for starting playing by clicking and the first frame picture corresponding to the video operation instruction for starting playing by clicking, the response time for starting playing of the video is detected as the detection of the video response speed. In the detection process of the video response speed, the response speed of the operation instruction for starting playing is detected, so that the quantity required by the screenshot can be reduced, the efficiency of searching the target screenshot can be improved, and the efficiency of the video response speed detection method is correspondingly improved.
