Detailed Description
Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Fig. 1 shows a flow diagram of a video processing method according to an embodiment of the present disclosure. The method is applied to the first terminal. The first terminal may be a terminal such as a mobile phone, a tablet Computer, a notebook Computer, or a PC (Personal Computer), which is not limited herein. As shown in fig. 1, the method includes steps S11 through S16.
In step S11, a screenshot instruction for a video is received.
In one possible implementation, the video may be played in the second terminal. The second terminal may be a terminal with a video playing function, such as a television, a PC, a notebook computer, or a tablet computer, which is not limited herein. In the implementation manner, when the second terminal plays the video, the video frame sequence of the video can be intercepted by the first terminal and the jigsaw puzzle is generated, so that cross-end screen capture and processing of the video are realized.
In another possible implementation, the video may be played in the first terminal.
In step S12, in response to the screenshot command, a first video frame sequence of the video is intercepted.
In one possible implementation, after intercepting the first video frame sequence of the video, the video frames of the first video frame sequence may be stored in a buffer in a temporal order of the video frames of the first video frame sequence.
For example, the first sequence of video frames includes video frames P1 through P10.
In step S13, the video frames including subtitles in the first video frame sequence are retained, and a second video frame sequence is obtained.
In one possible implementation, video frames of the first video frame sequence that contain subtitles may be retained in the buffer, and video frames of the first video frame sequence that do not contain subtitles may be deleted from the buffer.
For example, in the first video frame sequence, the video frame P2, the video frame P6, and the video frame P10 do not contain subtitles, and the video frame P1, the video frame P3, the video frame P4, the video frame P5, the video frame P7, the video frame P8, and the video frame P9 contain subtitles, it may be determined that the second video frame sequence includes the video frame P1, the video frame P3, the video frame P4, the video frame P5, the video frame P7, the video frame P8, and the video frame P9.
In step S14, in the second video frame sequence, a video frame with a subtitle different from that of the adjacent video frame and one of a plurality of consecutive video frames with the same subtitle are retained, so as to obtain a third video frame sequence.
In one possible implementation, a video frame of the second sequence of video frames that is different from the subtitle of the neighboring video frame and one of the consecutive video frames that have the same subtitle may be retained in the buffer, and other video frames of the consecutive video frames that have the same subtitle may be deleted from the buffer.
For example, in the second video frame sequence, the subtitles of the video frames P1, P3, P7, P8 and P9 are different from those of the adjacent video frames, and the subtitles of the video frames P4 and P5 are the same, the subtitles of the video frames P1, P3, P4, P7, P8 and P9 may be retained, or the subtitles of the video frames P1, P3, P5, P7, P8 and P9 may be retained, resulting in a third video frame sequence.
In step S15, in the third video frame sequence, a video frame whose image similarity to the adjacent video frame does not satisfy the condition and one of the consecutive video frames whose image similarity satisfies the condition are retained, and the subtitles of the consecutive video frames whose image similarity satisfies the condition are merged into the retained video frame, so as to obtain a fourth video frame sequence.
In one possible implementation manner, a video frame whose image similarity with an adjacent video frame does not satisfy the condition and one of consecutive video frames whose image similarity satisfies the condition may be retained in the buffer, and the other of the consecutive video frames whose image similarity satisfies the condition may be deleted from the buffer.
Wherein, the image similarity with the adjacent video frame does not satisfy the condition, which may mean that the image similarity with the adjacent video frame is less than the threshold; the image similarity with the neighboring video frame satisfying the condition may mean that the image similarity with the neighboring video frame is greater than or equal to a threshold. For example, the third sequence of video frames includes video frame P1, video frame P3, video frame P4, video frame P7, video frame P8, and video frame P9. If the image similarity between the video frame P4 and the video frame P3 is less than the threshold value, and the image similarity between the video frame P4 and the video frame P7 is less than the threshold value, it may be determined that the image similarity between the video frame P4 and the adjacent video frame does not satisfy the condition. If the similarity between the video frame P7 and the video frame P8 is greater than the threshold value, and the similarity between the video frame P8 and the video frame P9 is greater than the threshold value, it can be determined that the image similarities of the video frame P7, the video frame P8, and the video frame P9 satisfy the condition. In this case, one of the video frame P7, the video frame P8, and the video frame P9 may be retained. For example, the video frame P7 of the video frames P7, P8, and P9 may be retained, and the subtitles of the video frames P8 and P9 may be incorporated into the video frame P7. A fourth sequence of video frames may thus be obtained comprising video frame P1, video frame P3, video frame P4 and video frame P7, wherein video frame P7 contains subtitles for video frame P7, video frame P8 and video frame P9.
In step S16, the video frames in the fourth video frame sequence are spliced to obtain a mosaic corresponding to the fourth video frame sequence.
In a possible implementation manner, video frames in the fourth video frame sequence may be stitched into a long map from top to bottom in a time sequence, so as to obtain a mosaic corresponding to the fourth video frame sequence.
The embodiment obtains a jigsaw puzzle corresponding to a fourth video frame sequence by receiving a screenshot instruction for a video, responding to the screenshot instruction, capturing a first video frame sequence of the video, reserving video frames containing subtitles in the first video frame sequence to obtain a second video frame sequence, reserving a video frame which is different from subtitles of adjacent video frames and one video frame in a plurality of continuous video frames with the same subtitles in the second video frame sequence to obtain a third video frame sequence, reserving a video frame which does not satisfy a condition of image similarity with the adjacent video frames and one video frame in the plurality of continuous video frames with the condition of image similarity, merging the subtitles of the plurality of continuous video frames with the condition of image similarity into the reserved video frames in the third video frame sequence to obtain the fourth video frame sequence, and splicing the video frames in the fourth video frame sequence, the method for processing the video to obtain the jigsaw puzzle is simple in operation of the user, and the jigsaw puzzle can reflect rich video information. Since the puzzle obtained by video processing in this embodiment is a static image, not a moving image or a short video, it is easy to share. In addition, the data size of the puzzle obtained according to the embodiment is small, so that transmission traffic can be saved if the puzzle is shared, and storage space can be saved if the puzzle is stored locally.

In step S15, in the third video frame sequence, a video frame whose image similarity to the adjacent video frame does not satisfy the condition and one of the consecutive video frames whose image similarity satisfies the condition are retained, and the subtitles of the consecutive video frames whose image similarity satisfies the condition are merged into the retained video frame, so as to obtain a fourth video frame sequence.
In step S16, the video frames in the fourth video frame sequence are spliced to obtain a mosaic corresponding to the fourth video frame sequence.
In step S17, if a sharing request for the tile is received, the tile is shared with the sharing object corresponding to the sharing request.
Fig. 3 is a schematic diagram illustrating a sharing button in a video processing method according to an embodiment of the disclosure. As shown in fig. 3, after the tile corresponding to the fourth video frame sequence is obtained, the tile may be displayed, and the share button may be displayed. If the share button is triggered, it may be determined that a share request for the tile is received.
In one possible implementation, after obtaining a tile corresponding to the fourth video frame sequence, the method may further include: if a saving instruction for the puzzle is received, the puzzle can be saved to the local album. As shown in FIG. 3, while the tile is being presented, a save local button may also be displayed. If the save local button is triggered, it may be determined that a save instruction for the tile is received.
Fig. 4 illustrates an exemplary flow diagram of a video processing method according to an embodiment of the present disclosure. As shown in fig. 4, the method may include steps S21 through S28.
In step S21, a screen image of the second terminal is acquired.
In this embodiment, the screen image of the second terminal may be acquired in real time.
In step S22, the screen image of the second terminal is synchronously presented in the first terminal.
For example, the first terminal may acquire the screen image of the second terminal through Wi-Fi (Wireless Fidelity) technology, and may synchronously display the screen image of the second terminal in the first terminal.

Wherein, for step S25, refer to the description above for step S13.
In step S26, in the second video frame sequence, a video frame with a subtitle different from that of the adjacent video frame and one of a plurality of consecutive video frames with the same subtitle are retained, so as to obtain a third video frame sequence.
Wherein, for step S26, refer to the description above for step S14.
In step S27, in the third video frame sequence, a video frame whose image similarity to the adjacent video frame does not satisfy the condition and one of the consecutive video frames whose image similarity satisfies the condition are retained, and the subtitles of the consecutive video frames whose image similarity satisfies the condition are merged into the retained video frame, so as to obtain a fourth video frame sequence.

In step S121, in response to a screenshot start instruction, video frames of the video are continuously intercepted at a first frequency.
For example, the first frequency is 5 sheets/second.
In one possible implementation, the truncated video frames may be saved to a buffer.
As shown in fig. 5, for example, if it is detected that the dialog box is triggered, it may be determined that a screenshot start instruction is received.

Fig. 7 illustrates a schematic diagram of an end button in a video processing method according to an embodiment of the present disclosure. As shown in fig. 7, for example, if it is detected that the end button is triggered, it may be determined that a screenshot end instruction is received.
Fig. 8 is a schematic diagram illustrating a process of generating a mosaic in a video processing method according to an embodiment of the present disclosure.
