Embodiment 1

[0043] According to an embodiment of the present invention, an embodiment of a video playback method is also provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0044] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. figure 1 A hardware structural block diagram of a computer terminal (or mobile device) for implementing a video playing method is shown. Such as figure 1 As shown, the computer terminal 10 (or mobile device 10) may include one or more (shown by 102a, 102b, ..., 102n in the figure) processor 102 (the processor 102 may include but not limited to ...

Embodiment 2

[0130] The preferred implementation manner of the above-mentioned method of this embodiment will be further introduced below.

[0131] At present, people have higher and higher requirements for live broadcast and video viewing experience. From 1080p high-definition video to 4k high-definition, and now to 4k ultra-definition, it all shows that we are entering an increasingly "lossless" video viewing experience. In addition to being more and more satisfied with high-definition pixels, people's attention has begun to shift to the "high-definition" frame rate-that is, the high frame rate video viewing experience. A higher frame rate means smoother and more action (especially fast action) details. From the hardware point of view, when users buy mobile phones or display screens, they all consider whether it has a high refresh rate (90fps or even 120fps), "high refresh rate" or even the default configuration of flagship mobile phones.

Embodiment 3

[0163] According to an embodiment of the present invention, a method for implementing the above-mentioned figure 2 A video playback device for the video playback method shown.

[0164] Figure 8 is a schematic diagram of a video playback device according to an embodiment of the present invention. Such as Figure 8 As shown, the video playing apparatus 800 may include: a first acquiring unit 802 , a first determining unit 804 , a second determining unit 806 and a first playing unit 808 .

[0165] The first acquiring unit 802 is configured to acquire adjacent first video frames and second video frames in the decoded image of the target video.

[0166] The first determining unit 804 is configured to determine the target optical flow based on the first video frame and the second video frame.

[0167] The second determining unit 806 is configured to determine a third video frame based on the target optical flow, wherein the playing time of the third video frame is between the ...

Abstract

The invention discloses a video playing method, a storage medium, a processor and a system. The method comprises the following steps: in a decoded image of a target video, acquiring a first video frame and a second video frame which are adjacent to each other; determining a target optical flow based on the first video frame and the second video frame; a third video frame is determined based on the target optical flow, the playing time of the third video frame is between the playing time of the first video frame and the playing time of the second video frame, and the third video frame is used for enabling the video frame rate of the target video to be larger than a first threshold value; and sequentially playing the first video frame, the third video frame and the second video frame according to the playing time of the first video frame, the playing time of the third video frame and the playing time of the second video frame. According to the invention, the technical problem of large limitation of video playing is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a video playing method, storage medium, processor and system. Background technique [0002] At present, people's requirements for video viewing experience are getting higher and higher. From 1080p high-definition video to 4k high-definition video, and now the popularity of 4k ultra-definition, it all means that people are entering an increasingly "lossless" video viewing experience. In addition to being more and more satisfied with high-definition pixels, people's attention has begun to shift to high frame rate video viewing experience. [0003] In the prior art, the high refresh rate of the hardware needs to cooperate with the high frame rate of the video resource to be able to work. However, the high frame rate video has a high bit rate and requires a larger bandwidth, so there is a technical problem of large limitations in video playback. [0004] For the above problems, no e...
