The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a video playing method according to an embodiment of the present application, where the video playing method may be performed by a video playing device, and the video playing device may be implemented by software and/or hardware. The video playback device may be an electronic device or a chip or circuit of an electronic device. As shown in fig. 2, the method of the present embodiment may include:
s101, acquiring a current motion video of a user and a current played target video.
Specifically, an image pickup device is installed on the electronic equipment, and a current motion video of a user can be shot through the image pickup device on the electronic equipment. Optionally, when the sports teaching video is played initially, or when the user selects to start the video playing function provided in the embodiment of the present application, the electronic device shoots the current sports video of the user by starting the camera device, and simultaneously acquires the target video played currently.
In one implementation manner, the electronic device may be configured to capture the current motion video of the user in real time, capture the motion video of a preset duration (such as 2 minutes or 1 minute, etc.), and then execute S102 according to the captured motion video of the preset duration, or perform S102 while capturing, that is, collect real-time processing in real time.
In an embodiment, the video playing device in this embodiment may be a video playing application program (APP), specifically, for example, an exercise APP, where the exercise APP is installed and operated on an electronic device, and when a user opens the exercise APP and selects an exercise video to play, the video playing device may open a camera of the electronic device to capture a current exercise video of the user.
S102, determining the current movement rhythm of the user according to the current movement video of the user, and determining the current movement rhythm of the target person in the target video according to the target video, wherein the movement rhythm is the rhythm corresponding to the actions of completing the preset times.
Specifically, the movement rhythm is a rhythm corresponding to the action of completing the preset times, for example, a rhythm corresponding to the action of completing one time, a rhythm corresponding to the action of completing two times, and the like.
In this embodiment, the types of movements include arm movements, head shaking movements, leg movements, waist movements, crotch movements, and the like, and the completion of one movement may be when a certain part of the body moves from a starting position to a certain position and then returns from the position to the starting position. Taking the action of the arm as an example, when the arm moves from the initial position to a certain position and returns to the initial position from the position, the action is completed. The determination of the motion of other body parts is similar.
In this embodiment, alternatively, the corresponding rhythm of completing an action may be time (i.e. time consuming) of completing an action, and the time of completing an action may be time consuming when a part of the body moves from a starting position to a certain position and then returns from the position to the starting position. Accordingly, the movement rhythm in the embodiment may be time (i.e. time consuming) for completing the actions of the preset times, and if the preset times are two times, the movement rhythm may be time for completing the actions of the two times, and may be time for continuously completing the actions of the two times.
As an implementation manner, in S102, the determining the current motion tempo of the user according to the current motion video of the user, and determining the current motion tempo of the target person in the target video according to the target video may specifically include:
S1021, determining the time of each time the user completes an action according to the current motion video of the user.
Specifically, determining the time of each action of the user according to the current motion video of the user specifically may include:
s10211, sequentially performing image processing and human modeling on each frame of image of the current motion video of the user to obtain a human skeleton model corresponding to each frame of image.
Specifically, taking a frame of image as an example, image processing and human modeling can be performed on the frame of image to obtain a human skeleton model corresponding to the frame of image.
S10212, determining the human body action corresponding to each frame of image according to the human body skeleton model corresponding to each frame of image.
S10213, determining the time of each time of the user' S action according to the human action corresponding to each frame of image.
Specifically, the time for completing one action can be the time consumption when a certain part of the body moves from a starting position to a certain position and then returns to the starting position from the position, so that the time for completing one action of the user can be determined according to the human body action corresponding to each frame of image.
S1022, calculating the time of continuously completing the actions of the preset times according to the time cycle of each action of the user, calculating once each action of the preset times, and determining the current movement rhythm of the user according to the time of continuously completing the actions of the preset times, which is calculated by the cycle.
Specifically, the motion process is performed by one motion, for example, the preset times are two times, the time for the user to continuously complete the two motions is calculated, the time is calculated once for each two motions, the calculated time for the user to continuously complete the two motions is stored in the memory, then the time for the next user to continuously complete the two motions is calculated, the time for each calculated time for the user to continuously complete the two motions covers the time for the last calculated time for the user to continuously complete the two motions, namely, only the time for the latest calculated user to continuously complete the two motions is stored in the memory.
Wherein, optionally, determining the current movement rhythm of the user according to the time calculated by the cycle when the user continuously completes the actions for the preset times may be:
storing the latest calculated time for continuously completing the preset times of actions of the user in a memory, acquiring the time for continuously completing the preset times of actions of the user from the memory according to a preset period, and determining the acquired time for continuously completing the preset times of actions of the user as the current movement rhythm of the user.
The preset period may be 2s, 5s, 7s, etc., for example, the preset period is 5s, and the time for the user to continuously complete the preset times is obtained from the memory every 5s, and is determined as the current exercise rhythm of the user. It can be understood that the smaller the preset period, the shorter the time interval is for adjusting the playing speed of the target video, and the higher the accuracy is consistent with the motion rhythm of the user.
S1023, determining the time of each time the target person completes an action according to the target video.
The target person in the target video may be a person currently moving, and if there are a plurality of persons currently moving in the target video, a core person in the target video, such as a person located in the center of the target video, may be selected. The process of determining the time of each action of the target person according to the target video is similar to the process of determining the time of each action of the user according to the current motion video of the user, and the method specifically can comprise the following steps:
s10231, sequentially carrying out image processing and human modeling on each frame of image of the target video to obtain a human skeleton model corresponding to each frame of image.
S10232, determining the human body action corresponding to each frame of image according to the human body skeleton model corresponding to each frame of image.
S10233, determining the time of each time of the target person according to the human body action corresponding to each frame of image.
Specifically, the time for completing one action can be the time consumed when a certain part of the body moves from a starting position to a certain position and then returns to the starting position from the position, so that the time for completing one action of the target person can be determined according to the human action corresponding to each frame of image.
S1024, calculating the time of continuously completing the actions of the preset times according to the time cycle of each action of the target person, calculating once each action of the preset times, and determining the current movement rhythm of the target person according to the time of continuously completing the actions of the preset times by the target person calculated by the cycle.
Specifically, the motion process is performed by one motion, for example, the preset times are two times, the time for continuously completing the motion of the target person is calculated for two times, the time is calculated for each time of two times of motion, the calculated time for continuously completing the motion of the target person is stored in the memory, then the time for continuously completing the motion of the next target person is calculated, the time for continuously completing the motion of the target person each time is covered by the time for continuously completing the motion of the last calculated target person, namely, the time for continuously completing the motion of the last calculated target person is stored in the memory.
Wherein, optionally, determining the current movement rhythm of the target person according to the time of continuously completing the actions of the preset times by the target person calculated in a circulating way can be as follows:
And storing the time for continuously completing the preset times of actions of the target person which is calculated recently in a memory, acquiring the time for continuously completing the preset times of actions of the target person from the memory according to a preset period, and determining the acquired time for continuously completing the preset times of actions of the target person as the current movement rhythm of the target person.
The preset period may be 2s, 5s, 7s, etc., for example, the preset period is 5s, and the time for continuously completing the preset times of actions of the target person is obtained from the memory every 5s, and the time is determined as the current movement rhythm of the target person. It can be understood that the smaller the preset period, the shorter the time interval is for adjusting the playing speed of the target video, and the higher the accuracy is consistent with the motion rhythm of the user.
Optionally, in this embodiment, determining the current motion tempo of the user according to the current motion video of the user and determining the current motion tempo of the target person in the target video according to the target video may be performed simultaneously through two preset threads (e.g., a first thread and a second thread), where the two threads independently complete the acquisition of the motion tempo, and are not mutually affected. And acquiring the current movement rhythm of the user and the current movement rhythm of the target person from the memory according to a preset period through a preset third line. The three threads run in parallel at the same time, and the adjustment efficiency and the adjustment accuracy of the video playing speed can be further improved without mutual influence.
And S103, determining the play speed to be adjusted of the target video according to the current motion rhythm of the user and the current motion rhythm of the target person.
Specifically, the speed of adjustment can be determined according to the ratio of the current motion rhythm of the user to the current motion rhythm of the target person, and then the playing speed to be adjusted of the target video can be determined according to the speed of adjustment and the preset standard playing speed. And when the motion rhythm of the target person is slower than the current motion rhythm of the user, the playing speed of the target video is faster, and due to real-time dynamic adjustment, the motion rhythm of the target person can be finally realized to follow the motion rhythm of the user, the user experience is improved, and the body-building efficiency of the user is ensured.
As an implementation manner, S103 may specifically be:
s1031, determining the speed doubling according to the ratio of the time when the target person continuously completes the preset times of actions to the time when the user continuously completes the preset times of actions.
Alternatively, the ratio of the time when the target person continuously completes the preset number of actions to the time when the user continuously completes the preset number of actions may be determined as the adjustment multiplier.
Specifically, the adjustment multiplier speed may be determined according to a value obtained by dividing a time for the target character to continuously complete the preset number of times of actions by a time for the user to continuously complete the preset number of times of actions, where the adjustment multiplier speed is a multiplier speed of a preset standard playing speed, for example, a time for the target character to continuously complete the preset number of times of actions is y, and a time for the user to continuously complete the preset number of times of actions is x, where a value of y/x is the adjustment multiplier speed. For example, if the time y for the target person to continuously complete the two actions is 4s, the time x for the user to continuously complete the two actions is 2 seconds, and the value of y/x is 2, the motion rhythm of the user is faster than the motion rhythm of the target person in the target video, and the speed is adjusted to be 2; in contrast, if the time x for the user to continuously complete the two actions is 4 seconds, the time y for the target person to continuously complete the two actions is 3 seconds, and the value of y/x is 0.75, the motion rhythm of the user is slower than that of the target person in the target video, and the speed is adjusted to be 0.75.
S1032, determining the play speed to be adjusted of the target video according to the adjustment double speed and the preset standard play speed.
S104, playing the target video based on the playing speed to be adjusted.
Specifically, for example, the adjustment speed is 2, and the to-be-adjusted playing speed of the target video is 2 times the standard playing speed. Accordingly, the video playing device plays the target video at a speed 2 times the standard playing speed.
Alternatively, the smaller the preset number of times is set, for example, the shorter the preset period is set, for example, 2s, the higher the adjustment frequency of the video playing speed is, and thus the higher the accuracy of the adjustment is.
In one implementation manner, further, after S104, the method of this embodiment may further include:
if the playing speed to be adjusted is greater than a first threshold or less than a second threshold, displaying prompt information on an interface for playing the target video, wherein the prompt information comprises at least one of the playing speed to be adjusted, information for reminding a user of paying attention to the motion effect and information for indicating that the user is currently prohibited from starting the double-speed playing, and the first threshold is greater than the second threshold.
For example, the first threshold is 2 times of the standard playing speed, the second threshold is 0.5 times of the standard playing speed, at this time, prompt information is displayed on the interface of the playing target video, where the prompt information may include information for reminding the user of paying attention to the sports effect, and may further include a playing speed to be adjusted, for example, the playing speed to be adjusted is 2 times of the standard playing speed, the indication information is "currently playing at 2 times of the playing speed", or the playing speed to be adjusted is 0.5 times of the standard playing speed, and the indication information is "currently playing at 0.5 times of the playing speed". The prompt may also include information indicating that the user is currently prohibited from starting the dual-speed play.
