All other embodiments, which can be derived by a person skilled in the art from the embodiments shown, without inventive step, are within the scope of protection of the embodiments shown.
Referring to fig. 1, it shows a flow of a video playing control method for playing a picture video at two different playing rates at the same time to achieve differential playing of the video at the same time, where the video playing control method shown in fig. 1 may include the following steps:
101: and acquiring a first picture video of the first video and a second picture video of the first video. In this embodiment, the first picture video and the second picture video may belong to the first video, for example, the first picture video and the second picture video may belong to the same picture video of the first video, or the first picture video and the second picture video may belong to two at least partially different picture videos of the first video. A feasible way to acquire the picture video of one of the first picture video and the second picture video belonging to the first video may be, but is not limited to, the following feasible ways:
one possible way is to: randomly selecting a picture video from the first video, wherein the selected picture video at least comprises a frame of image picture;
another possibility is: selecting a picture video according to video parameters of a first video, wherein the video parameters of the first video include but are not limited to: the playing condition of each picture video in the playing condition of the at least one picture video belonging to the first video can be indicated by the playing times or the playing probability of the picture video, wherein the playing times indicate the playing times of the picture video in all the picture videos, and the playing probability indicates the playing probability of the picture video in all the picture videos.
The corresponding manner of selecting one picture video according to the video parameters of the first video may be: selecting a picture video according to at least one video parameter of the key frame, the playing time, the video abstract and the playing condition of at least one picture video belonging to the first video, for example, obtaining the picture video by at least one selection mode of selecting the picture video containing the key frame, selecting the picture video with the playing time in a preset time range corresponding to the playing time, selecting the picture video indicated by the video abstract and selecting the picture video with the playing condition better than that of other picture videos, wherein the picture video with the playing condition better than that of other picture videos can be determined according to the playing times or playing probability indicating the playing condition, for example, the playing times are taken as an example, the playing condition of the picture video with the playing times in the preset playing time range is better than that of the picture video with the playing times out of the preset playing time range, or the playing condition of the picture video with the playing times larger than that of other picture videos is better than that of other picture videos. In this embodiment, the preset time range and the preset playing time range may be determined according to practical applications, and this embodiment is not limited thereto.
The points to be explained here are: if the first picture video and the second picture video can be two picture videos which belong to the first video and are at least partially different from each other, at least one of the image pictures included in the first picture video and the image pictures included in the second picture video are different for the first picture video and the second picture video which are acquired in the feasible manner, for example, the image pictures included in the first picture video are as follows: the second picture video comprises the following picture pictures: image frame 2, image frame 3, and image frame 4. Of course, the image frames included in the first screen video and the image frames included in the second screen video may be different from each other, and the present embodiment is not limited to whether the image frames included in the first screen video and the image frames included in the second screen video are the same or not, and how many image frames are the same when the image frames included in the first screen video and the image frames included in the second screen video are the same.
In this embodiment, one of the first screen video and the second screen video is the screen video being recorded, and the other screen video is the screen video that has been recorded. The picture video that is being recorded is a picture video that is being recorded in real time by a terminal device (such as a viewfinder), and the picture video that has been recorded can be played and determined by the above feasible manner, for example, a picture video that has been recorded is randomly selected from the first video, or a picture video that has been recorded is selected according to the video parameters of the first video, so that the picture video that is being recorded is taken as one of the first picture video and the second picture video, and the picture video that has been recorded is taken as the other of the first picture video and the second picture video, so that the recording and playing of the video can be realized, and the playing effect can be known by playing the picture video that has been recorded.
If the first video obtained by the above video recording apparatus is expected to present a specific effect, such as a slow effect or a fast effect, the picture video that has been completely recorded in the first video may be used as one of the first picture video and the second picture video, so as to show whether the playing effect is the specific effect that is expected to be presented by playing the picture video, both the slow effect and the fast effect may be achieved by changing parameters of the picture video or by changing a recording rate, for example, by changing parameters of the picture video: the play-back time period of one frame of image picture is changed, such as by increasing the play-back time period of one frame of image picture to achieve a satisfying effect, while the play-back time period of one frame of image picture is decreased to achieve a quick effect or by changing. And by changing the recording rate may be: the fast and slow effect is obtained by recording at a rate greater than the normal recording rate, and the fast effect is obtained by recording at a rate less than the normal recording rate, which is an international recording standard set for the terminal device, such as 24 grids/second.
102: and determining a first playing speed corresponding to the first picture video and a second playing speed corresponding to the second picture video, wherein the first playing speed is different from the second playing speed.
It can be understood that: for any terminal device capable of playing the screen video, an international playing standard may be set for the terminal device, where the international playing standard is used to define a normal playing rate of the screen video played by the terminal device, such as 30 frames per second, and may also set a playing rate different from the normal playing rate for the terminal device, such as setting at least one playing rate smaller than the normal playing rate and at least one playing rate larger than the normal playing rate, so that two different playing rates may be selected from the set playing rates as the first playing rate and the second playing rate.
If one of the first playback rate and the second playback rate is a normal playback rate, and the other is a playback rate different from the normal playback rate, for example, any one of the set at least one playback rate smaller than the normal playback rate or any one of the set at least one playback rate larger than the normal playback rate.
Or the first playing speed and the second playing speed are both different playing speeds from the normal playing speed, for example, one of the first playing speed and the second playing speed is any one of the set at least one playing speed less than the normal playing speed, the other is any one of the set at least one playing speed greater than the normal playing speed, for example, the first playing speed and the second playing speed are two different playing speeds of the set at least one playing speed less than the normal playing speed, for example, the first playing speed and the second playing speed are two different playing speeds of the set at least one playing speed greater than the normal playing speed.
Here, it should be noted that: when one of the first picture video and the second picture video is the picture video which is being recorded, the playing speed corresponding to the recording speed of the picture video needs to be selected for the picture video which is being recorded so as to present the playing effect corresponding to the recording speed, thereby determining whether the presented playing effect is the desired playing effect.
103: the first picture video is played at the first playing speed in the first area, and the second picture video is played at the second playing speed in the second area, so that the picture videos are played at two different playing speeds simultaneously, and the purpose of playing the videos differently is achieved.
In this embodiment, the first area and the second area belong to a playing area of the same terminal device, or the first area and the second area belong to playing areas of different terminal devices, for example, the terminal device may be any device having a playing and displaying function, such as any device in a VR (Virtual Reality) device, an AR (Augmented Reality) device, a mobile terminal (e.g., a mobile phone), and the like.
The first picture video and the second picture video may be played in the same way, for example, the first picture video and the second picture video are played in any way of being directly displayed by the terminal device and being displayed through the projection function of other devices, or the first picture video and the second picture video are played in different ways, for example, one of the first picture video and the second picture video is directly displayed by the terminal device, the other one is displayed through the projection function of other devices, or one of the first picture video and the second picture video is displayed through the projection function of other devices, and the other one is directly displayed by the terminal device. As shown in fig. 2 and 3, which illustrate two ways of playing a first picture video and a second picture video, wherein fig. 2 illustrates that the first picture video can be directly displayed on the terminal device by the terminal device at a first playing rate, and the second picture video can be directly displayed on the terminal device by the terminal device at a second playing rate; fig. 3 shows one of the first picture video and the second picture video, for example, the first picture video is directly displayed on the terminal device by the terminal device, and the second picture video is displayed by the projection function of the other device.
For the first area and the second area of the present embodiment, one positional relationship of the first area and the second area may be: one of the first region and the second region is located in the other region, for example, the first region is located in the second region, or the second region is located in the first region, and a schematic view of the positional relationship thereof is shown in fig. 4, which shows that the second region is located in the first region. For an area located within an area, the manner of determining the area located within the area may be: randomly determining any one of a part of the area in the area, a preset area (i.e. a fixed area) in the selected area, and a part of the area in the selected area according to the video content of the picture video played in the area, wherein the criteria of the part of the area in the selected area according to the video content are as follows: the selected portion of the area reduces occlusion of a primary target in the video content, such as reducing occlusion of a character in the video content. The size and shape of the area located in the area may be determined according to practical applications, for example, the size and shape of the area located in the area may be set according to the video content in the area, which is not limited in this embodiment.
In this embodiment, another positional relationship of the first region and the second region may be: the first area and the second area are two non-overlapping areas, for example, the first area and the second area belong to a terminal device respectively, or one of the first area and the second area belongs to a terminal device and the other one belongs to a projection area of a device having a projection function, and the projection area is not overlapped with the area of the terminal device, or the first area and the second area are two non-overlapping areas of the same device, for example, two non-overlapping areas of the same terminal device or two non-overlapping areas of the device having the projection function.
The points to be explained here are: the two regions that do not overlap each other are regions where the picture videos are played, but it is not limited whether the sides of the two regions that do not overlap each other, as shown in fig. 5, although one of the two regions overlaps, the regions where the picture videos are played do not overlap, and in this case, the two regions are still considered as two regions that do not overlap each other.
According to the technical scheme, under the condition that the first picture video of the first video and the second picture video of the first video are obtained, the first playing speed corresponding to the first picture video and the second playing speed corresponding to the second picture video are determined, the first picture video is played in the first area at the first playing speed, the second picture video is played in the second area at the second playing speed, and the first playing speed and the second playing speed are different, so that the picture videos can be played at two different playing speeds at the same time, and the videos can be played differentially at the same time.
And the video recording and playing can be realized under the condition that the picture video which is being recorded is taken as one of the first picture video and the second picture video, and the picture video which is played and recorded is taken as the other one of the first picture video and the second picture video, and the playing effect can be known by playing the picture video which is recorded, so that whether the playing effect is a specific effect which is expected to be achieved or not is determined.
In the process of playing the picture video at two different playing rates, especially in the case that the playing effect is not the desired specific effect, the video playing control method shown in this embodiment may further adjust the picture video, and the flow thereof is shown in fig. 6, and may further include the following steps based on fig. 1:
104: and acquiring a first instruction, and adjusting the picture video corresponding to the first instruction in the first picture video and the second picture video according to the first instruction. Wherein adjusting the picture video corresponding to the first instruction includes but is not limited to: and adjusting at least one of the playing speed of the picture video corresponding to the first instruction and the display of the picture video corresponding to the first instruction in one of the first area and the second area.
The picture video corresponding to the first instruction may be determined according to identification information carried in the first instruction, where the identification information may point to the picture video to be adjusted, where the identification information may be identification information of the picture video, such as a name of the picture video, such as the first picture video, or the identification information may be position information of an operation body when the first instruction is generated, where the position information of the operation body points to a playing position where the picture video is located, so that the picture video corresponding to the first instruction may be determined according to the position information of the operation position. In this embodiment, the generation manner of the first instruction may be, but is not limited to, the following manner:
one way is as follows: the first instruction may be generated according to an operation of an operator on controls in an area where the first area and the second area are located, for example, a control for controlling at least one of a playback rate and display is set in the area where the first area and the second area are located, as shown in fig. 7, where the control (abbreviated as control 11) corresponding to the number 11 is used to control the playback rate, and the control (abbreviated as control 12) corresponding to the number 12 and the control (abbreviated as control 13) corresponding to the number 13 are used to control the display by a user.
And generating a first instruction corresponding to the control after the corresponding control is operated, wherein the adjustment of the first instruction is the same as the function of the control, if the function of the control is to control the playing speed, the first instruction is used for adjusting the playing speed of the picture video, so that the automatic adjustment of the playing speed is realized, and under the condition that the playing effect is not the expected specific effect, the playing effect can be close to the expected specific effect as much as possible by adjusting the playing speed.
In another mode: the first instruction is generated according to the posture of the operation body in the space, such as according to the gesture of the user in the space, and a gesture corresponding to the adjustment is set in this embodiment, so that the corresponding first instruction can be generated according to the detected gesture. If the gesture corresponding to the adjustment of the playing speed is set to be a sliding gesture, and the sliding distance and the sliding direction determine the adjustment of the playing speed, if the sliding direction is one of leftward sliding and rightward sliding, it indicates that the playing speed needs to be decreased, and the other indicates that the playing speed needs to be increased, and the larger the sliding distance is, the larger the adjustment range of the playing speed is, which is not described in this embodiment of the gesture for display adjustment.
In another way: the first instruction is based on the detected sound content, such as a sound indicating the adjustment of the screen video input by the user, and the first instruction is generated based on the sound content corresponding to the sound. If a user inputs a piece of information indicating which frame video to adjust, if the input is to adjust the playback rate of the first frame video, when adjusting one of the first frame video and the second frame video, a first instruction for adjusting the playback rate of the first frame video is generated.
And adjusting the display of the picture video corresponding to the first instruction in one of the first area and the second area includes but is not limited to: and adjusting at least one of the video content played by the picture video corresponding to the first instruction in one of the first area and the second area and the area occupied by the picture video corresponding to the first instruction in one of the first area and the second area.
The adjusting of the video content played by the picture video corresponding to the first instruction in one of the first area and the second area may be: and determining the area where the picture video corresponding to the first instruction is located, and adjusting the video content played in the area to update the picture video. If the picture video corresponding to the first instruction is the picture video which is played and recorded, under the condition that the first instruction is received, synchronizing the video content of the picture video which is played and recorded to the video content which is recorded at the current moment, and realizing the synchronous updating with the video.
If the first instruction is generated by clicking the control 13 shown in fig. 7, the control 13 is used to adjust the video content played in the area where the picture video is located, so that the video content played in the area where the picture video is located is updated under the condition that the first instruction corresponding to the control 13 is received, for example, the video content playing the picture video with the video recording completed is synchronized to the video content with the video recording completed at the current moment, so as to achieve the synchronous update with the video recording.
And adjusting an area occupied by the picture video corresponding to the first instruction in one of the first area and the second area may be: and adjusting the area occupied by the picture video corresponding to the first instruction, or interchanging the areas of the first picture video and the second picture video, namely adjusting the playing of the first picture video from the first area to the playing of the second area, and adjusting the playing of the second picture video from the second area to the playing of the first area.
If the obtained first instruction is generated by clicking the control 12 shown in fig. 7, the control 12 is used to adjust the area where the picture video is located, and if the area where the first picture video and the second picture video are located can be used to interchange, therefore, when the first instruction corresponding to the control 13 is received, the playing of the first picture video from the first area is adjusted to the playing of the second area, the playing of the second picture video from the second area is adjusted to the playing of the first area, and the interchange result is shown in fig. 8, where the direction of the arrow in the drawing shown in fig. 8 shows that the two picture videos played in the first area and the second area are interchanged.
According to the technical scheme, in the process of playing the picture video at two different playing rates, the picture video can be automatically adjusted, at least one of the playing rate and the display of the picture video is adjusted, and especially under the condition that the playing effect is not the expected specific effect, the playing effect can be made to be as close to the specific effect as possible by adjusting the playing rate.

Here, it should be noted that: when one of the first picture video and the second picture video is the picture video which is being recorded, the playing speed corresponding to the recording speed of the picture video needs to be selected for the picture video which is being recorded so as to present the playing effect corresponding to the recording speed, thereby determining whether the presented playing effect is the desired playing effect.
The playing unit 23 is configured to play the first picture video at the first playing rate in the first area, and play the second picture video at the second playing rate in the second area, so as to play the picture videos at two different playing rates at the same time, thereby achieving the purpose of playing the videos differently.
In this embodiment, the first area and the second area belong to a playing area of the same terminal device, or the first area and the second area belong to playing areas of different terminal devices, for example, the terminal device may be any device having a playing and displaying function, such as any device in a VR device, an AR device, a mobile terminal (e.g., a mobile phone), and the like.
The first picture video and the second picture video may be played in the same way, for example, the first picture video and the second picture video are played in any way of being directly displayed by the terminal device and being displayed through the projection function of other devices, or the first picture video and the second picture video are played in different ways, for example, one of the first picture video and the second picture video is directly displayed by the terminal device, the other one is displayed through the projection function of other devices, or one of the first picture video and the second picture video is displayed through the projection function of other devices, and the other one is directly displayed by the terminal device.
For the first area and the second area of the present embodiment, one positional relationship of the first area and the second area may be: one of the first region and the second region is located within the other region, e.g., the first region is located within the second region, or the second region is located within the first region. For the regions located in the region, the manner of determining the region located in the region may refer to the relevant description in the method embodiment, which is not described again in this embodiment.
In this embodiment, another positional relationship of the first region and the second region may be: the first area and the second area are two non-overlapping areas, for example, the first area and the second area belong to a terminal device respectively, or one of the first area and the second area belongs to a terminal device and the other one belongs to a projection area of a device having a projection function, and the projection area is not overlapped with the area of the terminal device, or the first area and the second area are two non-overlapping areas of the same device, for example, two non-overlapping areas of the same terminal device or two non-overlapping areas of the device having the projection function.
The points to be explained here are: the two regions that do not overlap each other are regions where the screen videos are played, but there is no limitation on whether the sides of the two regions that do not overlap each other, as shown in fig. 5, although one of the two regions overlaps, the regions where the screen videos are played do not overlap, and in this case, the two regions are still considered as two regions that do not overlap each other.
According to the technical scheme, under the condition that the first picture video of the first video and the second picture video of the first video are obtained, the first playing speed corresponding to the first picture video and the second playing speed corresponding to the second picture video are determined, the first picture video is played in the first area at the first playing speed, the second picture video is played in the second area at the second playing speed, and the first playing speed and the second playing speed are different, so that the picture videos can be played at two different playing speeds at the same time, and the videos can be played differentially at the same time.
And the video recording and playing can be realized under the condition that the picture video which is being recorded is taken as one of the first picture video and the second picture video, and the picture video which is played and recorded is taken as the other one of the first picture video and the second picture video, and the playing effect can be known by playing the picture video which is recorded, so that whether the playing effect is a specific effect which is expected to be achieved or not is determined.
However, in the process of playing the picture video at two different playing rates, especially in the case that the playing effect is not the desired specific effect, the video playing control device shown in this embodiment may further adjust the picture video, and the structure of the video playing control device shown in fig. 10 may further include, on the basis of fig. 9: and the adjusting unit 24 is configured to acquire the first instruction, and adjust, according to the first instruction, a picture video corresponding to the first instruction in the first picture video and the second picture video.
