It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a first flowchart illustrating a video frame capturing method according to an embodiment of the present disclosure. The video picture intercepting method comprises the following steps:
Specifically, the screen capture instruction may be effective only when the mobile terminal plays the video, or may be effective when the mobile terminal is in other states such as screen-off state and screen-on state, which is not limited herein. The screen capture instruction can be realized by clicking one or more physical keys on the mobile terminal by a user or carrying out specific touch operation on the screen.
The mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a personal digital assistant, and the like, and various application programs, such as applications with an entertainment function (e.g., a video application, a game application, and reading software) and applications with a service function (e.g., a map navigation application, a dining application, and the like), are stored in the mobile terminal.
And 102, acquiring the current target playing progress of the video when a screen capturing instruction is received.
Specifically, when a screen capture instruction of a user is detected and received, the current playing progress of the video is obtained, for example, the total screen viewing time is 45 minutes, and when the user triggers the screen capture instruction in 36 minutes, 10 seconds and 150 milliseconds, the current target playing progress of the video is 36 minutes, 10 seconds and 150 milliseconds. The API interface may also be called to obtain the target playing progress of the current video through the MediaPlayer type getCurrentPosition function, and if the target playing progress is 6 minutes, 10 seconds and 150 milliseconds, the returned number is: 370150 milliseconds.
The screen capturing instruction is implemented by sliding on the screen, and in order to determine whether the user captures the screen by sliding, a preset distance threshold value may be set, and when the sliding operation of the user reaches the preset distance threshold value, the screen capturing instruction is triggered. Therefore, when the video is played, the screen capture instruction is detected, and the screen capture instruction comprises the following steps:
when the video is played, if a sliding operation is detected and the sliding distance from the starting point to the end point of the sliding operation reaches a preset distance threshold, triggering the screen capturing instruction.
How to detect the sliding distance from the starting point to the ending point of the sliding operation of the user can be calculated by acquiring the coordinate values of the starting point of the screen clicked for the first time when the user carries out the sliding operation and the ending point of the screen separated by the finger and calculating the sliding distance of the sliding operation according to the coordinate values of the starting point and the ending point.
If the screen capture instruction is a sliding operation, the playing progress corresponding to the starting point of the sliding operation to the playing progress corresponding to the ending point can be determined as the target playing progress, so that the situation that when the screen capture instruction is triggered, the picture to be captured by the user is played completely and the playing progress corresponding to the picture to be captured by the user cannot be obtained due to the fact that the user may slide slowly is avoided. Therefore, obtaining the current target playing progress of the video may include:
acquiring a first playing progress corresponding to the starting point of the sliding operation;

and determining each playing progress from the first playing progress, the second playing progress and the first playing progress to the second playing progress as a target playing progress.
And 103, determining a target picture from the video source file according to the target playing progress, and taking the target picture as an intercepted picture corresponding to the screen intercepting instruction.
Specifically, after the corresponding target playing progress is obtained when the screen capture instruction is received, a video picture corresponding to the target playing progress needs to be determined from the video source file. An API interface may be called to obtain a picture corresponding to the target play progress through a getframeattattime function of the mediametadatagateway class. The video is composed of a plurality of video frames, each playing progress corresponds to one video frame, therefore, the video can be subjected to framing processing to obtain the video frame for each playing progress, and then the corresponding video frame is determined according to the obtained target playing progress. Therefore, determining a target picture from the video source file according to the target playing progress comprises:
performing frame division processing on the video to obtain a plurality of video frames, wherein each video frame corresponds to a playing progress;
and determining the video frame with the playing progress corresponding to the target playing progress as a target picture.

performing frame division processing on the video to obtain a plurality of video frames, wherein each video frame corresponds to a playing progress;
acquiring a first video frame corresponding to a target playing progress;
acquiring a second video frame corresponding to each playing progress in a preset time period before the target playing progress;
and determining the first video frame and the second video frame as target pictures.
If the screen capture instruction is a sliding operation, the video frames corresponding to the first playing progress, the second playing progress and each of the first playing progress to the second playing progress in step 102 may be determined as the target pictures. Therefore, determining a target picture from the video source file according to the target playing progress may further include:

and determining the video frames corresponding to each playing progress from the first playing progress, the second playing progress and each playing progress from the first playing progress to the second playing progress as the target pictures.
Specifically, since the picture directly obtained from the video source file is generally in the bitmap format, the picture in the format occupies a large storage space, and the picture in the JPG format is beneficial to storage and transmission. Therefore, a format conversion condition can be set, when the occupied capacity of the target picture is larger than the preset capacity of the storage space, the picture is subjected to format conversion, and the target picture after the format conversion is used as a capture picture corresponding to the screen capture instruction. Therefore, taking the target picture as the capture picture corresponding to the screen capture instruction may include:
judging whether the capacity occupied by the target picture is larger than the preset capacity of a storage space or not;
and if the capacity occupied by the target picture is larger than the preset capacity of a storage space, converting the file format of the target picture, and storing the target picture after the file format conversion in the storage space as an intercepting picture corresponding to the screen intercepting instruction.
