The following describes video playing provided by the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating steps of a video playing method according to an embodiment of the present invention, as shown in fig. 1, the method may include:
In the embodiment of the present invention, the current frame image and the frame image to be played are obtained, which may be frame images corresponding to each playing time sequence in a video obtained through video decoding, and based on the current playing time of the video, the frame images with the same playing time sequence as the current frame image are used, and then according to the playing time sequence of the video, all frame images which are not played after the current playing time are used as the frame images to be played. It should be noted that the video may be a video stored on the electronic device, or may be a video played online.
In the embodiment of the present invention, when the video is played at the N-speed, the first input may be received, and the N-speed of the video playing may be determined in response to the first input. Specifically, the first input may be an input operation performed by a user for a video playing speed, where the input operation may be a selection operation performed by the user according to at least one displayed video playing speed, or an input operation performed by the user in a video playing speed input field, and the input numerical value is used as the video playing speed determined by the user, or a voice input operation performed for the video playing speed input field, for example, a voice instruction "to adjust the video playing speed to double-speed playing" may be input, which is not limited by the present invention. Specifically, if the first input is a selection operation, the selected playback speed may be set as an N-speed of the video playback, and if the first input is an input operation, the input playback speed may be set as an N-speed of the video playback, where N is a positive number, N may be 0.5, 0.75, 1, 1.25, 1.5, and the like, and accordingly, the speed of the video playback is 0.5-speed, 0.75-speed, 1-speed, 1.25-speed, 1.5-speed, and the like. The user may perform a first input when the video playing speed needs to be adjusted, and accordingly, the electronic device may receive the first input. For example, assuming that the playing speed of the current video is normal playing, that is, one-time playing, the user performs the first input, and accordingly, the electronic device receives the first input indicating that the playing speed is two-time playing, it may be determined that the N-time speed of the video playing is two-time speed.
It should be noted that the video playing speed may be displayed on the video playing setting interface in a preset display style, and the specific style is not limited in the present invention. After entering the play setting interface, the user may execute a first input for the video play speed to adjust the video play speed. The video playing speed can also be displayed on the video playing interface, the display style is not limited in the invention, and the user can execute the first input aiming at the video playing speed on the video playing interface.
In the embodiment of the present invention, the repetition rate between the current frame image and the frame image to be played may be: the method comprises the steps of firstly determining the content appearing in a frame image to be played and the content appearing in a current frame image, and determining the ratio of the same content in the two contents in the frame image to be played as the repetition rate.
Specifically, a ratio between the area of the same content and the total area of the frame image to be played may be used as a repetition rate of the frame image to be played, or a ratio between the number of pixels included in the same content and the total number of pixels of the frame image to be played may be used as a repetition rate of the frame image to be played, which is not limited in this embodiment of the present invention. It should be noted that, the content appearing in the frame image to be played is the same as the content appearing in the current frame image, and whether the two contents are the same content may be determined by determining whether the parameter values corresponding to the color, shape, size, and the like of the contents are the same, where the contents may be a person, a scene, and the like, which is not limited in this embodiment of the present invention.
In the embodiment of the invention, the frame image to be played with the repetition rate matched with the preset repetition rate threshold corresponding to the N-fold speed is determined as the target frame image, the corresponding preset repetition rate threshold can be determined according to the N-fold speed of video playing, whether the repetition rate of the frame image to be played is matched with the preset repetition rate threshold is judged, and the frame image to be played with the repetition rate matched is taken as the target frame image. The preset repetition rate threshold value can be associated with each video playing speed in advance, so that the video playing speeds can correspond to the preset repetition rate threshold values one to one, and the size of the preset repetition rate threshold value is in negative correlation with the size of the video playing speed, that is, when the video playing speed is higher, the preset repetition rate threshold value corresponding to the video playing speed is smaller.
For example, the video playing speed is one-time speed, that is, when the video is played normally, the corresponding preset repetition rate threshold is 100%; when the video playing speed is 1.5 times, the corresponding preset repetition rate threshold value is less than 70%; when the video playing speed is 2 times, the corresponding preset repetition rate threshold value is less than 60%; when the video playing speed is 2.5 times, the corresponding preset repetition rate threshold value is less than 50%; when the video playing speed is 3 times, the corresponding preset repetition rate threshold value is less than 40%.
And 103, displaying the target frame image after the current frame image is displayed.
In the embodiment of the present invention, the video can be played according to the video playing speed selected by the user by displaying the target frame image after the current frame image is displayed.
It should be noted that, the target video image is displayed while corresponding audio information is also included, the audio corresponding to the target frame image may be played after the audio corresponding to the current frame image is played, or the corresponding audio may be played at equal intervals according to the video playing speed and the matching time interval determined according to the video playing speed, which is not limited in this embodiment of the present invention.
In summary, in the video playing method provided in the embodiment of the present invention, under the condition that the video is played at an N-speed, the current frame image and the frame image to be played are obtained, where the frame image to be played is a video frame image after the current frame image, then, according to the repetition rate between the current frame image and the frame image to be played, the target frame image is determined, the repetition rate of the target frame image is matched with the preset repetition rate threshold corresponding to the N-speed, and finally, after the current frame image is displayed, the target frame image is displayed. Therefore, the playing of the next frame of video image is determined according to the repetition rate of the video image, the number of the played video images can be reduced to a certain extent, the fast playing is ensured, the connection between the played video images is more natural and smooth, and the video playing effect can be improved.
Fig. 2 is a flowchart illustrating steps of another video playing method according to an embodiment of the present invention, as shown in fig. 2, the method may include:
Specifically, the step 101 may be referred to in an implementation manner of this step, which is not limited in this embodiment of the present invention.
Exemplarily, fig. 3 is a schematic diagram of a display video playing interface according to an embodiment of the present invention, as shown in fig. 3, a video playing progress bar 02 and a playing speed setting interface 03 are displayed on a display screen 01 of an electronic device, and the playing speed setting interface 03 includes a one-time fast forward, a two-time fast forward and a three-time fast forward. When the electronic device receives an input operation of a user for double-speed fast forwarding, the double-speed fast forwarding can be determined as the playing speed of the video.
In the embodiment of the present invention, the repetition rate between the comparison frame image and the current frame image may be determined by first determining whether the color of each object in the comparison frame image is the same as the color of the object in the current frame image, and if the colors are the same, determining that the two objects are the same object, and then determining the ratio of the same object in the comparison frame image.
It should be understood that the repetition rate between the comparison frame image and the current frame image is determined, and the change degree of the video content between different frame images can be determined, so that the target frame image to be displayed can be conveniently determined subsequently, and the video processing efficiency is improved.
It should be noted that the comparison frame image may be a video frame image that is not played after the current frame image, for example, the playing timing of the current frame image is 13 minutes 04 seconds 16 th frame, all the video frame images that are not played after the 13 minutes 04 seconds 16 th frame may be taken as frame images to be played, and the comparison frame image may be a frame image to be played next after the current frame image, that is, the comparison frame image may be a video image corresponding to the 13 minutes 04 seconds 17 th frame.
Optionally, the frame image to be played in the embodiment of the present invention may include k frame image groups to be played, and the method for determining and comparing frame images may further include: if the repetition rate of the p comparison frame images is greater than the preset repetition rate threshold value; determining the ratio of the p to the total number of images in the target image group; the target image group is a frame image group to be played to which the p comparison frame images belong; and if the ratio is greater than a preset ratio threshold, determining the frame image to be played in the next group of frame image groups to be played of the frame image to be played as the comparison frame image.
In the embodiment of the invention, the frame to be played can be divided into k frame image groups to be played, each frame image group to be played comprises at least two frame images to be played, wherein k is a positive integer. When the repetition rate between the comparison frame image and the current frame image is determined, if the repetition rate of the p comparison frame images is larger than a preset repetition rate threshold, determining the ratio of the p to the total number of images in a target image group, wherein the target image group is a frame image group to be played to which the p comparison frame images belong, and p is a positive integer.
For example, if the video playing speed is a double speed, the corresponding preset repetition rate threshold is less than 60%, and p is assumed to be 20, that is, if the repetition rate of 20 compared frame images is greater than 60%, the ratio between 20 and the total number of images in the target image group is determined, and if the total number of images in the target image group is 100, the ratio may be 0.2.
In the embodiment of the present invention, if the ratio is greater than the preset ratio threshold, the frame image to be played in the frame image group to be played next to the frame image to be played is determined as the comparison frame image, where when the ratio is greater than the preset ratio threshold, the frame image group to be played to which p comparison frame images belong is skipped, and the frame image to be played in the frame image group to be played next to the frame image to be played is determined as the comparison frame image, where the preset ratio threshold may be preset by a user according to an actual situation, for example, may be 90%. Therefore, the frame image to be played is divided into a plurality of image groups, when the repetition rate of the images with the number exceeding the preset number is larger than the preset repetition rate threshold value, the repetition rate of the rest of the images in the image group does not need to be detected, the image group can be directly skipped, the frame image to be played in the next image group is used as a comparison frame image, the repetition rate of each frame image to be played does not need to be determined, the time for image processing can be reduced, and the image processing efficiency is improved.
For example, in the frame image group to be played of the 1 st to 100 th frames, the repetition rate of 93 comparison frame images is greater than the preset repetition rate threshold, and since the ratio of the 93 comparison frame images to the total number of images in the frame image group to be played is 93%, and the ratio is greater than the preset ratio threshold 90%, the frame image group to be played of the 1 st to 100 th frames can be skipped, and the image group after the frame image group to be played of the 1 st to 100 th frames, that is, the frame image to be played in the frame image group to be played of the 101 st and 200 th frames, is determined to be the comparison frame image.
Specifically, the determination of the repetition rate between the comparison frame image and the current frame image may be implemented by the following steps 2021 to 2022.
Step 2021, determining the target number of the matched pixels in the comparison frame image and the current frame image according to the display parameters of the pixels in the comparison frame image and the display parameters of the pixels in the current frame image.
In the embodiment of the present invention, the target number of the pixels in the comparison frame image and the current frame image that are matched is determined, which may be determining whether the display parameter of each pixel in the comparison frame image is matched with the display parameter of the pixel at the corresponding position in the current frame image, counting the number of the pixels in the comparison frame image having the matched display parameters, and taking the number of the pixels as the target number.
In the embodiment of the invention, the display parameter can be the pixel value of the pixel point, and the gray characteristic, the contrast characteristic and the brightness characteristic of the pixel point can be embodied through the pixel value. It should be noted that the display parameters may also be gray scale values, contrast, brightness, and the like of the pixels. The display parameters of the pixel points reflect the display characteristics of the video content in the video image, and the target number of the pixel points matched with the current frame image in the comparison frame image is determined, so that whether the video content same as the current frame image exists in the comparison frame image or not and the ratio of the same video content in the comparison frame image can be determined, and the accuracy of calculating the repetition rate of the comparison frame image can be improved.
Step 2022, determining the repetition rate according to the ratio of the target number to the total number of the pixel points in the comparison frame image.
In the embodiment of the present invention, a ratio between the target number and the total number of the pixel points in the comparison frame image may be calculated, and the ratio is used as the repetition rate of the comparison frame image. For example, if the total number of pixels in the comparison frame image is 76800 and the target number is 25600, the ratio between the target number and the total number of pixels in the comparison frame image is 0.3333, and the repetition rate of the comparison frame image is 33.33%. The ratio of the target number to the total number of the pixel points in the comparison frame image is determined as the repetition rate of the comparison frame image, so that the change degree of video contents in different frame images can be reflected, the target frame image needing to be displayed can be conveniently determined subsequently, and the image processing efficiency is improved.
For example, the speed N times the video playing speed selected by the user is 1.5 times, the preset repetition rate threshold corresponding to the speed 1.5 times is less than 70%, and if the repetition rate of the comparison frame image is 63%, that is, the repetition rate of the comparison frame image is less than the preset repetition rate threshold, the comparison frame image may be determined as the target frame image. The comparison frame image with the repetition rate not greater than the preset repetition rate threshold is determined as the target frame image, so that the target frame image not only meets the video playing speed selected by the user, but also can ensure that the video contents among different played frame images are related, and the user is prevented from missing important video contents.
In the embodiment of the present invention, when the repetition rate of the comparison frame image is greater than the preset repetition rate threshold, the comparison frame image may be skipped, the frame image to be played next to the comparison frame image is used as a new comparison frame image, the repetition rate between the new comparison frame image and the current frame image is determined for the new comparison frame image, if the repetition rate of the new comparison frame image is not greater than the preset repetition rate threshold, the new comparison frame image is determined as a target frame image, if the repetition rate of the new comparison frame image is greater than the preset repetition rate threshold, the new comparison frame image is skipped, the frame image to be played next to the new comparison frame image is used as a comparison frame image, and the operation of determining the repetition rate between the comparison frame image and the current frame image is executed again until the target frame image is determined. By selectively skipping the frame images with the repetition rate larger than the preset repetition rate threshold value and taking the frame images to be played with the repetition rate smaller than or equal to the preset repetition rate threshold value as the target frame images, the frame images with the repetition rate lower and the video content containing more different contents can be prevented from being skipped, so that the video content is linked more naturally and smoothly, and the video playing effect can be improved.
Illustratively, the speed N of the video playing speed selected by the user is 1.5 times, the preset repetition rate threshold corresponding to the 1.5 times speed is less than 70%, the playing time sequence of the current frame image is 13 minutes 32 seconds 14 th frame, the playing time sequence of the comparison frame image is 13 minutes 32 seconds 15 th frame, and the repetition rate between the comparison frame image and the current frame image is 87 percent, namely, if the repetition rate of the comparison frame image is greater than the preset repetition rate threshold, the comparison frame image with the playing time sequence of 13 minutes, 32 seconds and 15 frames can be skipped, the frame image to be played with the playing time sequence of 13 minutes, 32 seconds and 16 frames can be used as a new comparison frame image, the repetition rate between the new comparison frame image and the current frame image is determined, and the repetition rate of the new comparison frame image is 68 percent, that is, if the repetition rate of the new comparison frame image is smaller than the preset repetition rate threshold, the new comparison frame image of the 16 th frame with the playing time sequence of 13 minutes and 32 seconds may be determined as the target frame image.
For example, fig. 4 is a schematic diagram of displaying a video image according to an embodiment of the present invention, and as shown in fig. 4, a video image and a video playing progress bar 02 are displayed on a display screen 01 of an electronic device, where the video image is a current frame image, and the playing timing is 12' 36 ″ 14. Fig. 5 is a schematic diagram of another embodiment of displaying a video image, as shown in fig. 5, a frame image to be played is displayed on a display screen 01, and the playing timing of the frame image to be played is 12' 36 ″ 17. The repetition rate between the frame image to be played and the current frame image can be determined to be 69%, when the video playing speed selected by the user is 1.5 times, the corresponding preset repetition rate threshold value is less than 70%, and the frame image to be played can be determined to be the target frame image because the repetition rate of the frame image to be played meets the preset repetition rate threshold value; when the video playing speed selected by the user is 2 times, the corresponding preset repetition rate threshold value is less than 60%, and the frame image to be played can be skipped over because the repetition rate of the frame image to be played does not meet the preset repetition rate threshold value.
And step 205, displaying the target frame image after the current frame image is displayed.
For example, the playing timing of the current frame image is 18 minutes, 26 seconds and 16 frames, and the playing timing of the target frame image is 18 minutes, 41 seconds and 06 frames, so that the target frame image of 18 minutes, 41 seconds and 06 frames can be displayed after the current frame image of 18 minutes, 26 seconds and 16 frames is displayed.
Optionally, the determining, according to the display parameter of each pixel in the comparison frame image and the display parameter of each pixel in the current frame image, the target number of pixels matching in the comparison frame image and the current frame image may include:
for any first pixel point in the comparison frame image, determining display position information of the first pixel point and display position information of each pixel point of the current frame image, and determining a second pixel point corresponding to the position of the first pixel point in the current frame image; if the pixel value of the first pixel point is the same as the pixel value of the second pixel point, determining that the first pixel point is matched with the second pixel point; determining the number of first pixel points of a target to obtain the target number; the target first pixel point is a first pixel point with a matched second pixel point.
In the embodiment of the present invention, the display position information of the pixel point may be a coordinate position of the pixel point in the image, specifically, the position of the pixel point in the image may be indicated based on a coordinate system established in the horizontal direction and the vertical direction on the basis of each pixel point on the image, for example, the pixel point located in the first row and the fourth column on the image, and the display position information of the pixel point may be (1, 4). Determining a second pixel point corresponding to the position of the first pixel point in the current frame image, wherein the pixel point on the current frame image, which is the same as the display position information of the first pixel point, can be used as the second pixel point corresponding to the position of the first pixel point in the current frame image according to the display position information of the first pixel point in the comparison frame image. For example, if the display position information of the first pixel point a on the frame image is compared to (12,15), the pixel point B with the display position information of (12,15) on the current frame image is used as the second pixel point corresponding to the first pixel point in the current frame image, that is, the display position information of the second pixel point is (12, 15).
In an embodiment of the present invention, the pixel value of the pixel point may be a channel value of each color of the pixel point in a Red-Green-Blue (RGB) color space, and may include a channel value of an R channel, a channel value of a G channel, and a channel value of a B channel, for example, a black RGB value is (0,0,0), a white RGB value is (255 ), and a Red RGB value is (255,0, 0). When the pixel value of the first pixel point is the same as the pixel value of the second pixel point, it can be determined that the first pixel point is matched with the second pixel point, for example, the pixel value of the first pixel point is (255,128,43), the pixel value of the second pixel point is (255,128,43), and the pixel value of the first pixel point is the same as the pixel value of the second pixel point, it can be determined that the first pixel point is matched with the second pixel point. The number of the first pixel points having the matched second pixel points is used as the target number, for example, when there are 452 first pixel points having the matched second pixel points, the target number is 452. By determining whether the pixel value of each pixel point in the comparison frame image is the same as the pixel value of the pixel point in the current frame image at the corresponding display position, whether the display content in the comparison frame image is the same can be determined, and then the comparison frame image and the current frame image can be used for determining the repetition rate, so that the accuracy of processing the image can be improved.
Optionally, the determining, according to the display parameter of each pixel in the comparison frame image and the display parameter of each pixel in the current frame image, the target number of pixels matching in the comparison frame image and the current frame image may further include:
dividing the comparison frame image in a preset dividing mode to obtain at least one first sub-region, and dividing the current frame image to obtain at least one second sub-region; for any first subregion, determining a second subregion corresponding to the position of the first subregion in the current frame image according to the display position information of the pixel points in the first subregion and the display position information of the pixel points in each second subregion in the current frame image, and obtaining a third subregion; if the first pixel mean value is the same as the second pixel mean value, determining that the first sub-area is matched with the third sub-area; the first pixel mean value is the mean value of the pixel values of the pixel points in the first sub-area, and the second pixel mean value is the mean value of the pixel values of the pixel points in the third sub-area; and calculating to obtain the target quantity according to the quantity of the first sub-areas of the third sub-areas which are matched with each other and the quantity of the pixel points contained in the first sub-areas.
In the embodiment of the present invention, at least one first sub-region is obtained by comparing the frame image according to a preset dividing mode, and at least one second sub-region is obtained by dividing the current frame image according to the preset dividing mode, for example, the preset dividing mode is a ten-equal dividing mode of equally dividing the area, 10 first sub-regions can be obtained by comparing the frame image, and 10 second sub-regions can be obtained by dividing the current frame image. And taking the second sub-area corresponding to the position of the first sub-area in the current frame image as a third sub-area according to the display position information of the pixel points in each first sub-area and the display position information of the pixel points in each second sub-area in the current frame image. And if the average value of the pixel values of the pixel points in the first sub-area is the same as the average value of the pixel values of the pixel points in the third sub-area, determining that the first sub-area is matched with the third sub-area.
In the embodiment of the present invention, the target number is calculated according to the number of the first sub-regions where the matched third sub-regions exist and the number of the pixel points included in the first sub-regions, for example, assuming that the number of the first sub-regions where the matched third sub-regions exist is 12, and the number of the pixel points included in each first sub-region is 100, the target number may be 1200. The average values of the pixel values of the two areas at the same position are compared by dividing the areas on the comparison frame image and the current frame image, and when the average values of the pixel values of the areas are the same, the pixel values of the pixel points in the two areas can be considered to be the same, so that the time for processing data can be saved, and the calculation efficiency can be improved.
Optionally, the method for determining the target frame image in the embodiment of the present invention may further include: if the repetition rate of m continuous comparison frame images is larger than the preset repetition rate threshold, selecting n comparison frame images from the m comparison frame images as the target frame images.
In the embodiment of the invention, when m comparison frame images continuously appear and the repetition rate of each comparison frame image is greater than the preset repetition rate threshold, n comparison frame images are selected from the m comparison frame images to be used as target frame images, wherein m and n are positive integers respectively, and n is less than m. For example, when the repetition rate of 10 comparison frame images appearing consecutively is greater than the preset repetition rate threshold, 2 comparison frame images may be selected from the 10 comparison frame images as the target frame image. Therefore, the problem that when a plurality of frame images with repetition rates larger than the preset repetition rate threshold value appear, the plurality of frame images can be skipped all at once according to the video playing speed, so that the relevance of the video contents among the plurality of frame images is low can be avoided, and the video contents acquired by a user can be ensured to be coherent.
Optionally, the method for determining the target frame image in the embodiment of the present invention may further include: if the repetition rate of the target frame image is smaller than a first specified value, increasing the preset repetition rate threshold; if the repetition rate of the target frame image is greater than a second specified value, reducing the preset repetition rate threshold value; wherein the first specified value and the second specified value are both smaller than the preset repetition rate threshold, and the first specified value is smaller than the second specified value.
In this embodiment of the present invention, the first specified value may be a repetition rate specified by a user in advance, for example, may be 20%. When the repetition rate of the target frame image is less than the first designated value, the preset repetition rate threshold may be increased by increasing an adjustment value based on the preset repetition rate threshold, where the adjustment value may be preset according to actual conditions, for example, may be 5%. The second specified value may be a repetition rate specified in advance by the user, for example, may be 60%. When the repetition rate of the target frame image is greater than the second designated value, the adjustment value may be subtracted from the preset repetition rate threshold to lower the preset repetition rate threshold. It should be noted that both the first specified value and the second specified value are smaller than the preset repetition rate threshold, and the first specified value is smaller than the second specified value. Therefore, when the repetition rate of the target frame image is low, the condition for determining the target frame image can be relaxed by increasing the preset repetition rate threshold, and when the video content changes greatly, the video image with the high repetition rate can be selected as the transition image, so that the played video content is more continuous, and the user can check the video content conveniently. When the repetition rate of the target frame image is high, the preset repetition rate threshold value is reduced, so that the condition for selecting the target frame image can be tightened, the high repetition rate of the video content is avoided, and the video watching efficiency of a user is reduced.
For example, assuming that the preset repetition rate threshold is 70%, when the repetition rate of the target frame image is smaller than the first specified value, the preset repetition rate threshold may be increased, that is, the increase is 75%; when the repetition rate of the target frame image is greater than the second specified value, the preset repetition rate threshold may be decreased, i.e., decreased to 65%.
The process that the invention can realize is: the video playing speed N times input by a user is obtained, the repetition rate of the frame image to be played is calculated, and the video can be played in a fast forward mode according to the repetition rate. For example, the video image of the first frame is a current frame image of the user, the repetition rate of the video image of the second frame with the first frame is 65%, and the repetition rate of the video image of the third frame with the first frame is 57%, if the video playing speed currently selected by the user is 1.5 times, the corresponding preset repetition rate threshold is less than 70%, because the repetition rates of the video image of the second frame and the video image of the third frame both satisfy the preset repetition rate threshold corresponding to 1.5 times, the video image of the second frame can be played, and the video image of the third frame is played; if the video playing speed currently selected by the user is 2 times speed and the corresponding preset repetition rate threshold is less than 60%, the video image of the second frame can be skipped to play the video image of the third frame because the repetition rate of the video image of the second frame does not meet the preset repetition rate threshold corresponding to the 2 times speed and the repetition rate of the video image of the third frame meets the preset repetition rate threshold corresponding to the 2 times speed.
To sum up, in the video playing method provided in the embodiment of the present invention, a current frame image and a frame image to be played are obtained when a video is played at an N-fold speed, where the frame image to be played is a video frame image after the current frame image, then a frame image to be played next to the current frame image is used as a comparison frame image, a repetition rate between the comparison frame image and the current frame image is determined, if the repetition rate is not greater than a preset repetition rate threshold, the comparison frame image is determined as a target frame image, if the repetition rate is greater than the preset repetition rate threshold, the frame image to be played next to the comparison frame image is used as the comparison frame image, and an operation of determining the repetition rate between the comparison frame image and the current frame image is executed again until the repetition rate of the comparison frame image is not greater than the preset repetition rate threshold, the comparison frame image is determined as the target frame image, finally, after the current frame image is displayed, the target frame image is displayed. Therefore, the playing of the next frame of video image is determined according to the repetition rate of the video image, the comparison frame image with the repetition rate not greater than the preset repetition rate threshold value is determined as the target frame image, the target frame image can meet the video playing speed selected by a user, association of video contents in different played frame video images can be guaranteed, the number of played video images can be reduced to a certain extent, the fast playing is guaranteed, the linkage between the played video images is more natural and smooth, and the video playing effect can be improved.
