Fig. 1 is a flowchart of steps of a video preview method according to an embodiment of the present invention, and as shown in fig. 1, the method may include:
In the embodiment of the present invention, an application of a mobile terminal generally adopts a mode of a flow list to store and display a flow, specifically, referring to fig. 2, which shows an interface diagram of a flow list provided in the embodiment of the present invention, the application of the mobile terminal 10 may provide a flow list 20, and add flows 30 such as text, images, videos, and the like in the flow list 20 in a block mode, where the block has a corresponding boundary and occupies a certain area in the flow list 20, the flow list 20 has a fixed-size display area 201 for displaying the content therein on a screen of the mobile terminal 10, and for a block 301 corresponding to a video flow, a key frame image 302 may also be displayed to achieve a preview effect.
Moreover, the information flow list 20 may receive a sliding touch operation of the user to perform a pull-up and a slide-down operation, and in addition, a slide bar 202 may be displayed on one side of the information flow list 20, so that when the information in the information flow list 20 flows too much, the user may quickly pull up or slide down the information flow list 20 by operating a slide block 203 on the slide bar 202 and precisely locate the information flow list 20 at a certain position.
Further, the block corresponding to each information stream 30 has a certain size, and a user can enter the detail interface corresponding to the information stream 30 by clicking the block corresponding to the information stream 30, so as to browse the detailed information of the information stream 30, for example, when the user clicks the block 301 corresponding to the video information stream, the video information stream can be played. Moreover, the position of the block changes with the sliding of the user on the information flow list 20, for example, when the user manipulates the slider 203 to move downward, the block 301 corresponding to the video information flow moves upward.
In this step, referring to fig. 3, a structure diagram of an information stream list according to an embodiment of the present invention is shown, in fig. 3, it is assumed that an information stream list 20 includes 8 information streams 30, each information stream corresponds to one block, where information streams 2 and 4 are video information streams, where a presentation area 201 is a fixed location area, and the information stream list 20 changes a location corresponding relationship with the presentation area 201, so that the presentation area 201 presents the information stream 30 corresponding to the block located therein, in this embodiment of the present application, based on a location of the block corresponding to a target information stream in the information stream list 20, it may be determined whether the block corresponding to the target information stream enters the presentation area 201.
And 102, when the target video enters a display area of the information flow list, displaying the key frame image corresponding to the target video and the display area according to the position corresponding relation of the target video and the display area.
In the embodiment of the present invention, the target video enters the display area of the information stream list, specifically, the target video may overlap with the position of the display area, and preferably, in the embodiment of the present invention, the display area of the target video enters the information stream list such that the target video completely overlaps with the display area, for example, referring to fig. 3, the blocks corresponding to the information stream 4, the information stream 5, and the information stream 6 completely overlap with the display area 201, so that the preview content can be displayed, while the information stream 3 and the information stream 7 only partially overlap with the display area 201, and the preview content can be displayed when the target video completely enters the display area 201.
In the embodiment of the present invention, a frame refers to a single image picture of a minimum unit in a video, which is equivalent to each frame shot on a motion picture film, and on a time axis of the video, the frame is represented as one frame, and a key frame may refer to a frame where a key action in the motion or change of an entire character or an object of the video is located, or may be a frame picture in the video defined by other rules.
Specifically, in the embodiment of the present invention, the video corresponding to the target video has a playing duration of a certain time, and has key frame images such as a cover and a drama, and in addition, in the process of playing the video, one picture extracted at intervals of a preset time may be used as a key frame image, and all the obtained key frame images are sorted according to the playing sequence.
In addition, as for the display area, the size and the position of the display area are fixed, so that the whole display area can be divided into a plurality of areas, and the corresponding relation between each area and the key frame image is established, namely the corresponding relation between the position of the target video and the display area and the key frame image of the target video is obtained, so that when the target video is in different areas in the display area, the target video is mapped to the specific key frame image for display according to the corresponding relation, and a user can conveniently preview the video stream in the process of pulling the information stream list.
For example, referring to fig. 3, the presentation area 201 may be divided into three areas from top to bottom, assuming that three key frame images are extracted from the video corresponding to the video information stream 4, the first key frame image may be bound to the first area, the second key frame image may be bound to the second area, and the third key frame image may be bound to the third area, where it is shown in fig. 3 that the block corresponding to the video information stream 4 is located in the first area, at this time, the block corresponding to the video information stream 4 may display the first key frame image, when the block corresponding to the video information stream 4 is located at the position of the information stream 5 in fig. 3, at this time, the block corresponding to the video information stream 4 is located in the second area, the block corresponding to the video information stream 4 may display the second key frame image, when the block corresponding to the video information stream 4 is located at the position of the information stream 6 in fig. 3, at this time, the block corresponding to the video information stream 4 is located in the third area, and the block corresponding to the video information stream 4 can display the third key frame image.
Therefore, the embodiment of the invention achieves the effect of displaying different key frame images corresponding to the target video when the target video is at different positions according to the corresponding relation between the target video and different positions of the display area, the preview process is shorter and controllable, the preview effect is improved, in addition, only the key frame images are displayed in the preview process, the flow of the mobile terminal is saved, and the consumption of the memory space of the mobile terminal is reduced.
In summary, in the video preview method provided in the embodiment of the present invention, a position of a target video in an information stream list is determined, where the information stream list includes at least one video; when the target video enters the display area of the information flow list, the key frame images corresponding to the target video and the display area are displayed according to the position corresponding relation between the target video and the display area.
Fig. 4 is a flowchart illustrating steps of another video previewing method according to an embodiment of the present invention, as shown in fig. 4, the method may include:
The implementation manner of this step is similar to the implementation process of step 101 described above, and the embodiment of the present invention is not described in detail here.
Specifically, in the embodiment of the present invention, the key frame image may be used as a carrier for previewing video stream information, and a user may roughly browse the content of the video stream information by watching the key frame image of the video stream information.
Further, when the target video does not enter the display area of the information flow list, the application of the mobile terminal may locally calculate or pull the key frame data of the video corresponding to the target video from the server side.
Optionally, step 202 may further include:
in the substep 2021, when the target video does not enter the display area of the information stream list, the playing time duration corresponding to the target video is obtained.
In this step, the video corresponding to the target video generally has a certain playing time t, and the corresponding playing time may be obtained by analyzing the video.
And a substep 2022, extracting a frame of key frame image from the video corresponding to the target video at preset time intervals according to the playing time length to obtain a plurality of key frame images of the video.

In this step, the extracted multiple key frame images may be sorted to obtain a certain logical order, and there are various sorting methods, for example, the key frame images may be sorted according to the extraction time order of the key frame images to obtain a key frame image sequence, and in addition, the key frame images with higher importance may be arranged in front and the key frame images with lower importance may be arranged in back, for example, for a movie video stream, a cover image may be set at the start position of the key frame image sequence, and the dramas may be arranged in the remaining positions in order from high to low importance.
And 204, dividing the display area into a plurality of position intervals.
Referring to fig. 6, a corresponding relationship diagram of a key frame image and a display area is shown, wherein, since the size and the position of the display area 201 are fixed, the whole display area 201 can be divided into n position intervals.

And step 206, when the target video enters the display area of the information flow list, determining a target position interval corresponding to the target video according to the position corresponding relation between the target video and the display area.
And step 207, determining a target key frame image for displaying according to the mapping corresponding relation between the target position interval and the mapping.
Specifically, referring to fig. 6, if the target video enters the position interval 1, the target video may further determine that the target key frame image is the key frame 1 according to the position corresponding relationship with the position interval 1, and if the target video enters the position interval 2, the target video may further determine that the target key frame image is the key frame 2 according to the position corresponding relationship with the position interval 2.
Further, referring to fig. 7, which shows an interface diagram of a video preview method, referring to a state a, when a user slides up the information stream list 20, so that the target video 301 partially enters the display area 201 of the information stream list 20, when entering a state b, when the target video 301 completely enters the display area 201 of the information stream list 20, the display of the key frame image 1 may be performed, when entering a state c, when the target video 301 enters the top area of the display area 201 of the information stream list 20, the display of the key frame image n may be performed, when entering a state d, when the target video 301 exits the display area 201 of the information stream list 20, the display of the key frame image may be stopped.
