Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a video playing control method, electronic equipment and a medium, wherein the video playing control method can automatically adjust the playing parameters of a video.
Fig. 1 is a flowchart illustrating a method for controlling video playback according to an embodiment of the present invention. As shown in fig. 1, the method for controlling video playback applied to an electronic device includes:
In one embodiment of the present invention, the first video may refer to a video currently being played by the electronic device, and the recording of the second video may refer to a recording of an action of the user imitating a play action in the video currently being played by the electronic device.
And 102, under the condition that the target user action in the second video is not matched with the target playing action in the first video, adjusting the video playing parameters of the first video.
In one embodiment of the invention, the target user action comprises at least two user actions in at least two video frames in the second video, and the target playback action comprises at least two playback actions in at least two video frames in the first video. If the electronic device detects that the target user action in the second video is not matched with the target playing action in the first video, the video playing parameters of the first video are automatically adjusted.
In the embodiment of the invention, when the user imitates the playing action, the electronic equipment continuously records the user action to obtain the second video, and adjusts the video playing parameter of the first video under the condition that the target user action in the second video is not matched with the target playing action in the first video. The electronic equipment can automatically adjust the playing parameters of the first video according to the comparison between the recorded second video and the target playing action in the first video, the user does not need to interrupt the current learning state, the playing speed or the playing progress is manually adjusted, and the complex operation degree of the user is reduced.
In the embodiment of the invention, the electronic equipment can continuously record the second video under the condition of playing the first video, so that the continuity of recording the second video is improved.
In one embodiment of the present invention, if there are at least two users in front of the screen of the electronic device, the user closest to the electronic screen may be taken as a first target user, and the electronic device records a second video including the first target user.
If the number of the users closest to the electronic screen is greater than or equal to two, the central position of the screen of the electronic device can be used as a preset area, the user which is located at the central position of the screen of the electronic device and is closest to the screen of the electronic device is used as a second target user, and the electronic device records a second video including the second target user.
In addition, the user can set the identification area on the screen by himself, the user of the identification area is used as a third target user, and the electronic device records a second video including the third target user.
In an embodiment of the present invention, step 101 is described in detail by taking the first video as a dance video and the target playing motion as a dance motion as an example.
In the process of playing the dance video by the electronic equipment, the user can simulate the dance action in real time in front of the screen of the electronic equipment. At this time, the electronic device may record a second video corresponding to the user imitating the dance motion in real time.
In the embodiment of the invention, the electronic equipment can acquire the action of the user for imitating the target playing action in real time by recording the second video corresponding to the dance action in real time, so that the video playing parameters can be automatically adjusted more accurately according to the real-time imitation target playing action of the user in the following process.
In one embodiment of the present invention, it may be determined whether the target user action matches the target play action according to a similarity between the first user action included in the target user action and the first play action included in the target play action.
For example, if the similarity between the first user action included in the target user action and the first playing action included in the target playing action is smaller than a preset threshold, it is determined that the target user action is not matched with the target playing action; and if the similarity between the first user action included in the target user action and the first playing action included in the target playing action is not smaller than a preset threshold value, determining that the target user action is matched with the target playing action.
The preset threshold value can be set by a user according to own requirements, or can be automatically set by the electronic equipment. In some embodiments, in order to ensure the accuracy of the adjustment of the video playing parameters, the preset threshold may be set to be high. In other embodiments, the preset threshold may be set to be lower if the learning confidence of the user can be enhanced. The value of the preset threshold is not limited at all.
As shown in fig. 2a, fig. 2a is a schematic diagram of a target playing action in a first video according to an embodiment of the present invention. Taking the nth frame of video frame as an example, as can be seen from fig. 2a, the first playing action in the target playing actions corresponding to the nth frame of video frame in the first video is shown in fig. 2 a.
Fig. 2b shows a first user action in the target user actions corresponding to the nth frame of video frame in the second video recorded by the electronic device, where fig. 2b is a schematic diagram of the target user action in the second video according to an embodiment of the present invention.
As can be seen from comparing fig. 2a and fig. 2b, the hand motion and the step motion of the user are not consistent, which may cause the similarity between the first user motion in the target user motion and the first playing motion in the target playing motion shown in fig. 2b to be smaller than the preset threshold, that is, the target user motion and the target playing motion are not matched. Wherein N is understood to be a positive integer.
In the embodiment of the invention, the electronic device can determine whether the imitated target playing action of the user is accurate by judging the similarity between the first user action in the target user actions and the first playing action in the target playing action, so that the video playing parameters can be automatically adjusted subsequently when the target user action is determined not to be matched with the target playing action.
In another embodiment of the present invention, it may also be determined whether the action consistency degree of the target user action is consistent with the action consistency degree of the target playing action according to the first user action included in the target user action and the first playing action included in the target playing action, so as to determine whether the target user action is matched with the target playing action.
For example, when determining whether the motion consistency of the target user motion is consistent with the motion consistency of the target play motion, each video frame in the first video may be compared with each video frame in the second video starting from a starting video frame in the first video including the target play motion and a starting video frame in the second video.
If the next N frames of video frames after the initial video frame of the first video are all matched with the next N frames of video frames of the initial video frame of the second video one by one (namely the first playing action in each video in the next N frames of video frames of the first video is matched with the first user action in each video frame in the next N frames of video frames of the second video), the action consistency degree of the target user is determined to be consistent with the consistency degree of the target playing action, and the action of the target user is matched with the target playing action.
For example, the first video includes 3 video frames, the second video includes 3 video frames, and if the first frame of the first video is used as the start video frame of the first video, the second frame of the second video is used as the start video frame of the second video. And if the second frame video frame of the first video is matched with the second frame video frame of the second video and the third frame video frame of the first video is matched with the third frame video frame of the second video, the target user action is considered to be matched with the target playing action.
However, if the next N frames of video frames after the starting video frame of the first video are not completely matched with the next N frames of video frames of the starting video frame of the second video one by one (that is, the first play action in at least one video frame of the next N frames of video frames of the first video is different from the corresponding first user action in the next N frames of video frames of the second video), it is determined that the action consistency of the target user is inconsistent with the consistency of the target play action, and the target user action is not matched with the target play action.
For example, if the next N video frames of the first video do not match the next N video frames of the second video one by one, but match the next N + D0 video frames of the second video one by one, it is determined that the action consistency of the target user is not consistent with the consistency of the target play action, and the action of the target user is not matched with the target play action.
As an example, referring to fig. 3, fig. 3 is a schematic diagram illustrating a degree of inconsistency of action consistency between a target user action and a target play action according to an embodiment of the present invention.
The first video comprises 3 video frames, the second video comprises 3 video frames, and if the first frame of the first video is used as the starting video frame of the first video, the second frame of the second video is used as the starting video frame of the second video. Then if the second frame video frame of the first video does not match the second frame video frame of the second video (i.e., the next 1 frame video frame of the first video does not match the next 1 frame video frame of the second video), but matches the third frame video frame of the second video (i.e., the next 1 frame video frame of the first video does not match the next 1+1(D0) frame video frame of the second video), the target user action is considered not matching the target play action.
In the embodiment of the invention, whether the action consistency degree between the action of the target user and the action of the target playing is consistent or not is judged, so that whether the simulated target playing action of the user keeps up with the playing progress of the video or not can be determined, and the video playing parameters can be automatically adjusted when the action of the target user is determined to be not matched with the action of the target playing.
In an embodiment of the present invention, if the target user action and the target playing action are not matched due to the similarity not reaching the preset threshold, the playing speed may be reduced according to the similarity between the target user action and the target playing action.
For example, when the similarity between the target user action and the target playback action is 50%, the playback speed may be reduced by 0.75 times the initial playback speed, and when the similarity between the target user action and the target playback action is 70%, the playback speed may be reduced by 0.9 times the initial playback speed.
In another embodiment of the present invention, the target video segment including at least the first video may also be played in a loop K times according to the similarity between the target user action and the target playing action. Wherein K is understood to be a positive integer. Alternatively, K may be a default or may be set by the user.
For example, when the similarity between the target user action and the target play action is 50%, the target video segment including at least the first video may be played in a loop 5 times, and when the similarity between the target user action and the target play action is 70%, the target video segment including at least the first video may be played in a loop 3 times.
In another embodiment of the present invention, if the similarity between the target playing motion and the target user motion does not reach the preset threshold, the target area may be enlarged, displayed and played.
For example, if the electronic device detects that the similarity of the motions of the hand positions in the first video and the second video does not reach the preset threshold, the motions of the hand positions (target areas) may be amplified and played during playing, and the motions may be played according to the number of times of loop playing corresponding to the similarity.
In the embodiment of the invention, the playing speed corresponding to the similarity is determined according to the similarity between the target user action and the target playing action and the preset corresponding relation between the similarity and the playing speed; or, determining the playing speed corresponding to the similarity according to the similarity between the target user action and the target playing action and the preset corresponding relation between the similarity and the playing speed. The video playing parameters can be automatically adjusted after the target user action is determined to be not matched with the target playing action, the user is not required to interrupt the learning state of the user to manually adjust the video playing parameters, the complexity of user operation is reduced, and the current learning state of the user is not required to be interrupted, so that the electronic equipment can continuously record the second video, and the phenomenon of interruption when the second video is recorded is avoided.
In another embodiment of the present invention, if the action consistency is inconsistent, the action of the target user and the action of the target playing are not matched, the playing speed and the number of times of the circular playing of the video can be automatically adjusted, so that the playing of the video can better meet the requirement of the user.
In one embodiment of the present invention, the first video may include a plurality of video segments, for example, the plurality of video segments included in the first video may be a first video segment, a second video segment, a third video segment, and the like, which are divided according to the play time length of the first video.
For example, a first video with a playing time of 60 minutes can be divided into a first video segment (0-20 minutes), a second video segment (21-40 minutes) and a third video segment (41-60 minutes).
After the video playing parameters are adjusted, the video clip where the target playing action is located can be replayed only according to the adjusted video playing parameters until the target user action is matched with the target playing action, and then the next video clip is played.
For example, if the video segment in which the target playing action is located is the first video segment, when playing is performed according to the adjusted video playing parameters, the first video segment may be played only according to the adjusted video playing parameters, and the second video segment and the third video segment may be played after the target user action and the target playing action are matched.
According to the video playing control method provided by the embodiment of the invention, the video playing parameters of the first video are adjusted through the second video under the condition that the target user action in the second video is not matched with the target playing action in the first video, so that the electronic equipment can play the first video at least comprising the target playing action again according to the adjusted video playing parameters. The electronic equipment can automatically adjust the playing speed or the playing progress according to the second video obtained by recording the action of the target user for simulating the target playing action in real time, the user is not required to interrupt the current learning state, the playing speed is manually adjusted or the playing progress is manually adjusted, and the complex operation degree of the user is reduced.
In another embodiment of the present invention, taking the nth frame of video frame as an example, with continuing reference to fig. 3, as can be seen from fig. 3, the nth frame of video frame of the first video does not match the nth frame of video frame of the second video, but matches the N + D0 th frame of video frame of the second video.
Therefore, in order to adjust the playing parameters of the video more accurately, D0 may be recorded before step 102, where D0 is a positive integer.
At this time, the playback speed in the video playback parameters may be reduced by D0 frames per unit time. In addition, if the playing speed in the video playing parameters at this time and the lowest playing speed satisfy the preset relationship, the video can be played circularly according to the lowest playing speed. The preset relationship may be that the playing speed in the video playing parameters is very close to the minimum playing speed, and the video can be played in a circulating manner. The number of times of loop playing and the minimum playing speed can be preset.
In the embodiment of the present invention, if there is a match between the nth frame video frame in the first video and the N + D0 th frame video frame in the second video, it may be shown that the current playing speed is D0 frames faster per unit time than the action of the target user imitating the target playing action, and therefore, reducing the playing speed by D0 frames per unit time may make the playing speed of the target video more consistent with the actual imitation situation of the target user.
In an embodiment of the present invention, if the next N frames of video frames in the first video match the next N frames of video frames in the second video one by one, but the next N + M frames in the first video do not match the next N + M frames in the second video, but match the next N + M + D1 frames in the second video, it may be considered that the action consistency between the target user action and the target playing action is inconsistent, that is, the target user action and the target playing action are not matched.
For example, the first video includes 4 frames of video frames, the second video includes 4 frames of video frames, and if the first frame of the first video is used as the start video frame of the first video, the second frame of the second video is used as the start video frame of the second video. If the next 1 frame of the starting video frame in the first video frame (i.e., the 2 nd frame video frame in the first video) matches with the next 1 frame of the starting video frame in the second video frame (i.e., the 2 nd frame video frame in the second video), but the next 1+1(N + M) frame of the starting video frame in the first video (i.e., the 3 rd frame video frame in the first video) does not match with the next 1 frame of the starting video frame in the second video frame (i.e., the 3 rd frame video frame in the second video), but matches with the next 1+1+1(N + M + D1) frame of the starting video frame in the second video (i.e., the 4 th frame video frame in the second video), it can be considered that the degree of coherence between the target user action and the target play action is inconsistent, i.e., the target user action does not match with the target play action.
Therefore, in order to adjust the playing parameters of the video more accurately, the timestamps and D1 corresponding to the N + M video frames may be recorded before step 102. It should be understood that both M and D1 are positive integers.
In another embodiment of the present invention, if the consistency of the target user actions is inconsistent with the consistency of the target playing actions, a first time interval between a first time corresponding to a first user action in the target user actions and a second time corresponding to a second user action in the target user actions needs to be further determined. Wherein, it should be understood that, when judging the consistency of the actions, the first user action and the second user action should be two consecutive user actions.
Then, a second time interval between a third time corresponding to a third play action and a fourth time corresponding to a fourth play action in the target play actions is determined, and similarly, the third play action and the fourth play action are taken as continuous play actions.
And then, calculating the time difference between the first time interval and the second time interval according to the obtained first time interval and the second time interval, and adjusting the video playing parameter corresponding to the third time and the fourth time in the first video under the condition that the time difference is greater than a preset time difference threshold value, wherein the video playing parameter comprises the playing speed or the circulating playing times.
If the consistency between the target user action and the target playing action is consistent, the time difference between the first time interval and the second time interval should be small, even 0. Therefore, whether the consistency degree of the target user action and the target playing action is consistent or not is indicated by the preset threshold value.
For example, the preset threshold is set to 2 seconds, and the electronic device determines that the first time interval is 10 seconds. When the second time interval is 5 seconds, it means that the time interval between two consecutive playing actions in the first video is 5 seconds, and when the user imitates the playing action in the first video, the time interval between two consecutive user actions is 10 seconds, the time difference between the first time interval and the second time interval is 5 seconds, which is greater than the preset threshold value of 2 seconds, and it is necessary to adjust the corresponding video playing parameter between the third time and the fourth time in the first video.
The adjusting of the video playing parameter corresponding to the third time and the fourth time in the first video may be determining a target video frame number played between the third time and the fourth time, and then decreasing the video playing speed by the target video frame number per unit time.
In addition, if the video playing speed and the lowest playing speed at this time satisfy the preset relationship, the first video at least including the target playing action can be played circularly according to the lowest playing speed. The number of times of the loop playing can be preset.
In the embodiment of the invention, the electronic equipment can determine the specific video frame with discontinuous target user action through the time difference, so that the video playing parameters can be automatically and pertinently adjusted, and the user does not need to interrupt the current learning state of the user, and manually adjust the playing speed or manually adjust the playing progress.
The above embodiment describes a case where the electronic device has one screen, and a video playing method provided by a real-time embodiment of the present invention and applied to an electronic device having two screens is described in detail below with reference to fig. 6.
In an embodiment of the present invention, if the electronic device may include the first screen and the second screen, a flow of the method for controlling video playing may be as shown in fig. 4, where fig. 4 is a schematic flow chart of a method for controlling video playing according to another embodiment of the present invention.
Wherein the target user action is an action by the first user and the second user to mimic the target play action in the first video.
In step 404, when the playing parameter includes a playing speed, a target playing speed of the target video is determined based on a size relationship between the adjusted video playing speed corresponding to the first user and the adjusted video playing speed corresponding to the second user.
For example, the smaller video playback speed of the adjusted video playback speed corresponding to the first user and the adjusted video playback speed corresponding to the second user may be used as the target playback speed, or the larger video playback speed may be used as the target playback speed.
In the embodiment of the present invention, when the electronic device has two screens, the playing parameters of the two screens of the electronic device may be played according to the setting (according to the slower playing speed) preset by the user, or the playing parameters of the two screens of the electronic device may be played according to the setting (according to the faster playing speed) preset by the user.
