Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Example one
An embodiment of the present invention provides a method for performing a video screenshot, and as shown in fig. 1, a processing flow of the method may include the following steps:
step 101, in the process of decoding and playing the target video, storing a preset number of latest decoded image frames in a cache.
And 102, when a screenshot command is received, acquiring at least one image frame from the image frames in the cache, and storing the image frame as a screenshot image.
In the embodiment of the invention, in the process of decoding and playing the target video, a preset number of latest decoded image frames are stored in the cache, and when a screenshot command is received, at least one image frame is obtained from the image frames in the cache and is stored as the screenshot image.
Example two
The embodiment of the invention provides a method for carrying out video screenshot, and the execution main body of the method is a terminal. The terminal may be a mobile terminal, such as a mobile phone, a tablet computer, and the like.
The process flow shown in fig. 1 will be described in detail below with reference to specific embodiments, and the contents may be as follows:
step 101, in the process of decoding and playing the target video, storing a preset number of latest decoded image frames in a cache.
Wherein, the target video is any video selected to be played by the user.
In implementation, when a user needs to view a certain video (i.e., a target video), taking the target video as an example of a network video, the user may start a video player and select the target video, and the video player may connect to a corresponding video server through a URL (Uniform Resource Locator) of the target video and obtain video data of the target video, at this time, a kernel of the video player may sequentially decode image frames in the video data, and the video player may play the decoded image frames. The video player may request a certain buffer space for storing decoded image frames and the like, and may preset the maximum number of image frames stored in the buffer and set a certain deletion mechanism. In this way, a certain number of the most recently decoded image frames may be maintained in the buffer.
Alternatively, the mechanism for controlling the number of frames in the buffer may be varied, and one possible processing method is given below: in the process of decoding and playing a target video, when decoding of one image frame is completed, if the number of the image frames in the cache is less than the preset number, the image frame obtained by current decoding is stored in the cache, and if the number of the image frames in the cache is equal to the preset number, the image frame stored in the cache firstly is deleted, and the image frame obtained by current decoding is stored in the cache.
In implementation, a video player may decode and play a certain video (i.e., a target video), when the video player decodes to obtain an image frame, on one hand, the image frame may be played, and on the other hand, the image frame may be stored in a buffer, at this time, it may be determined whether the number of image frames stored in the buffer reaches a preset number, if the number of image frames in the buffer is less than the preset number, the image frame obtained by current decoding is stored in the buffer, and if the number of image frames in the buffer is equal to the preset number, the image frame stored in the buffer first may be deleted, and the image frame obtained by current decoding is stored in the buffer. Therefore, when the number of the image frames stored in the cache is smaller than the preset number, the image frames obtained by the latest decoding of the video player can be stored in the cache, and the number of the image frames stored in the cache is continuously increased along with the continuous sequential decoding of the image frames in the target video until the preset number is reached. And when the number of the image frames stored in the buffer memory is increased to the preset number, keeping the number of the image frames in the buffer memory unchanged until the target video is decoded.
And 102, when a screenshot command is received, acquiring at least one image frame from the image frames in the cache, and storing the image frame as a screenshot image.
In implementation, a technician may set a video capture function in a system program, where the start of the video capture function may be set according to actual requirements, for example, the video capture function is started after a video player buffers video data to be played for 5 seconds, or the video capture function is started when the video player is started. A video capture button may be provided at a designated location on the video player and may be set to a useable state, such as being highlighted by grey, when the video capture function is initiated.
As shown in fig. 2, when a user needs to capture a video currently played by a certain video player, a video capture button in the video player may be clicked, the video player receives a capture instruction carrying a player identifier, and the system program may determine, according to the player identifier, a video player corresponding to the player identifier, and select one or more image frames in a cache corresponding to the video player, and store the image frames as capture images in an assigned capture directory. For example, the first two image frames of the currently played image frame may be selected in the buffer, or the currently played image frame and the first two image frames of the image frame may be selected together as the screenshot image.
Optionally, the manner of selecting the screenshot image in the cache may be various, and several possible selection manners are given as follows:
in the first mode, when a screenshot command is received, the previous image frame of the currently played image frame is obtained from the image frames in the cache and stored as a screenshot image.
In implementation, the currently played image frame is stored in the buffer while being played, if the data volume of the image frame is large, the time consumption of the storage process may be long, and in order to improve the screenshot efficiency, when a screenshot instruction is received, the previous image frame of the currently played image frame stored in the buffer may be stored in a designated screenshot directory as a screenshot image.
And in the second mode, when a screenshot command is received, acquiring the currently played image frame from the image frames in the cache, and storing the image frame as a screenshot image.
In implementation, in some cases, the accuracy of the screenshot is required, and in order to improve the accuracy of the screenshot, the currently playing image frame stored in the cache may be taken as the screenshot image when the screenshot instruction is received.
Optionally, a screenshot interface may be preset for the video player, and when performing video screenshot, the system program may obtain a screenshot image through the screenshot interface, and correspondingly, the processing manner of step 102 may be: and when a screenshot command is received, acquiring at least one image frame from the image frames in the cache through a screenshot interface preset in a video player playing the target video, and storing the image frame as a screenshot image.
In implementation, a technician may set up various interfaces to the video player in the system program, which may include a screenshot interface. When receiving a screenshot instruction, the system program can select one or more image frames from the image frames in the corresponding cache of the video player through the screenshot interface and store the image frames as screenshot images in a specified screenshot directory.
Optionally, a certain execution trigger condition may be set for the step 102, and the corresponding processing procedure of the step 102 may be as follows: when receiving a screenshot command, if the next image frame of the currently played image frame is not stored locally, acquiring at least one image frame from the image frames in the cache and storing the image frame as a screenshot image. On the other hand, when receiving the screenshot command, if the next image frame of the currently played image frame is stored locally, decoding the next image frame, and storing the image frame obtained by decoding as the screenshot image.
In implementation, the screenshot interface may be preset for the video player. When receiving a screenshot instruction, the system program can search in a decoding thread of the video player through the screenshot interface to determine whether the decoding thread contains a next image frame of the currently played image frame, and if the decoding thread contains the next image frame of the currently played image frame, the system program can decode the next image frame in the decoding thread and store the decoded image frame as a screenshot image in an appointed screenshot directory. If the decoding thread does not include the next image frame, for example, the target video has been decoded and played, or the video player does not buffer corresponding data of the target video due to network reasons, at this time, at least one image frame may be selected from the image frames in the buffer memory, and stored as a screenshot image in a designated screenshot directory.
Alternatively, the terminal may be installed with a plurality of video players, which may include a system player and a non-system player, and an application program for integrating and invoking the video players may be installed in the terminal. When a video needs to be played, the user can run the application program, select a video player from the application program, and invoke the video player selected by the user to play the video.
Optionally, if the video player for decoding and playing the target video is a system player, when the target video is played, starting a video screenshot function, and repeatedly starting an inner core of the video player, acquiring playing time points corresponding to each image frame in the target video through the inner core, and storing the playing time points; when a screenshot command is received, determining and decoding the image frames corresponding to the screenshot time points according to the playing time points corresponding to the acquired image frames and the screenshot time points carried in the screenshot command, and storing the decoded image frames as screenshot images.
In implementation, when the system player is started, the start of the video screenshot function of the system player can be set according to actual requirements, which can refer to the above related contents. When the video screenshot function is started, the kernel of the system player can be called repeatedly while the target video is played, the head information of the target video is obtained and analyzed, the playing time points corresponding to all the image frames in the target video are obtained, and the playing time points are stored. When a user clicks a video screenshot button, a system player acquires a current playing time point on a playing progress bar as a screenshot time point to generate a screenshot instruction, receives the screenshot instruction, searches playing time points corresponding to the screenshot time point from playing time points corresponding to all image frames in a stored target video, decodes the image frames in the target video corresponding to the searched playing time points, and can use the decoded image frames as screenshot images.
In the embodiment of the invention, in the process of decoding and playing the target video, a preset number of latest decoded image frames are stored in the cache, and when a screenshot command is received, at least one image frame is obtained from the image frames in the cache and is stored as the screenshot image.
