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.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

The embodiment of the invention provides a method for prompting video content interaction positions, which is applied to an electronic terminal, wherein the electronic terminal can be an electronic device with a video playing function, such as a mobile phone, a computer and the like.

Referring to fig. 1, the method for prompting the video content interaction position includes:

step 101, obtaining an interactive file corresponding to a target video.

It should be noted that the target video is a video file with a preset duration, and preferably, the target video is a video file including advertisements and red-covered points. The interactive file comprises: at least one interactive picture and the corresponding relation between each interactive picture and a video frame in a target video; the interactive picture is in equal proportion to the video frame. Preferably, the interactive picture may be a mask made from the video frame. For example, a picture masking technique is used to make a mask for a video frame of a target video, and the made mask is used as an interactive picture in an interactive file. The interactive file is used for displaying prompt information at the position of the playing picture, which is provided with the interactive function, in the process of playing the target video, so that a user is prompted to determine where interaction can be carried out. The interactive file can be generated in advance according to the target video, and then when the target video is obtained, the interactive file corresponding to the target video is obtained at the same time. Of course, after the target video is obtained, the corresponding interactive file may also be obtained according to the information of the target video. For example, storing an interactive file corresponding to a target video in a network server, and acquiring the address of the interactive file in the network server when the target video is acquired; and then acquiring the interactive file from the network server according to the address. After the target video and the interactive file are acquired, the target video and the interactive file are stored in a local standby mode.

In the interactive file, each interactive picture corresponds to at least one video frame. The number of the video frames corresponding to each interactive picture can be determined according to requirements. If the identified object or person in the target video is relatively immobile, the number of the interactive pictures can be properly reduced, that is, the number of the video frames corresponding to each interactive picture can be properly increased; if the identified object or person in the target video moves rapidly, the number of the interactive pictures can be increased appropriately, that is, the number of the video frames corresponding to each interactive picture can be decreased appropriately. The position of the identified object and the person is the position where the prompt interactive prompt information is expected to be displayed. Preferably, each interactive picture has a different timestamp, and the corresponding relationship between the interactive picture and the video frame can be established according to the timestamp of the interactive picture and the timestamp on the video frame, but is not limited thereto. For example, all interactive pictures in the interactive file can be orderly arranged, and each interactive picture has a unique position serial number; and establishing a corresponding relation between the interactive pictures and the video frames according to the position serial numbers of the interactive pictures and the positions of the video frames in the target video.

And 102, in the playing process of the target video, determining a target interaction picture corresponding to the currently played video frame according to the corresponding relation.

It should be noted that the target interactive picture is one of at least one interactive picture in the interactive file. Playing a video frame at each playing moment, and then determining an interactive picture corresponding to the video frame played at the playing moment, namely a target interactive picture, according to the played video frame and the corresponding relation. Therefore, in the process of playing the target video, one target interactive picture can be determined for each playing time. Preferably, the target interactive pictures determined at the adjacent playing time points can be the same or different.

Step 103, determining a target image area in the currently played video frame according to the position of the first area in the target interactive picture.

It should be noted that the first area is a partial area in the target interactive picture, and a figure enclosed by edges of the first area may be a regular figure or an irregular figure. Because the interactive picture is in equal proportion to the video frame; preferably, the target image area is an area of the first area mapped in the currently played video frame; that is to say, the position of the first region in the target interactive picture is the same as the position of the target image region in the currently playing video frame. Of course, the target image area may also be a part of the area mapped in the currently playing video frame for the first area; or the target image area is in the current playing video frame and comprises an area of the first area mapped in the current playing video frame.

And 104, displaying preset prompt information in a target image area in the currently played video frame to prompt a user that the target image area is provided with interactive information.

It should be noted that the preset prompt information may be prompt animation, prompt text, highlight, etc.

In the embodiment of the invention, an interactive file corresponding to a target video is obtained; wherein, the interactive file includes: at least one interactive picture and the corresponding relation between each interactive picture and a video frame in a target video; the interactive picture is in equal proportion to the video frame. And in the playing process of the target video, determining a target interactive picture corresponding to the currently played video frame according to the corresponding relation. Determining a target image area in a currently played video frame according to the position of a first area in a target interactive picture in the target interactive picture; by utilizing the equal proportion relation between the interactive picture and the video frame, the target image area corresponding to the first area can be quickly and accurately positioned. Compared with the method for directly determining the target image area in the video frame with complex content, the method is simpler. And displaying preset prompt information in a target image area in the currently played video frame to prompt a user that the target image area is provided with interactive information. The preset prompt information is directly displayed in the target image area for interaction, so that the prompt information can move along with a playing picture in the video playing process and is not limited to a fixed position. Meanwhile, the video content with the interactive information in the playing picture can be accurately locked, and the visual experience of the user is improved.

Fig. 2 is a flowchart illustrating steps of another method for prompting a video content interaction location according to an embodiment of the present invention, as shown in fig. 2, the method includes:

step 201, acquiring an interactive file corresponding to a target video.

Step 202, in the playing process of the target video, according to the corresponding relation, determining a target interaction picture corresponding to the currently played video frame.

Step 203, detecting the transparency of the pixel points in the target interactive picture, and determining a first position of a region where the pixel points with the first transparency are located in the target interactive picture.

It should be noted that the first region of the target interactive picture has a first transparency, and the second region has a second transparency, and the first transparency is different from the second transparency, wherein the second region is a region of the target interactive picture other than the first region. Therefore, the first area can be determined through the transparency of the pixel points in the target interactive picture. The color of the first region is a preset color, and the preset color may be any color, such as black, but is not limited thereto. The color of the second region may be the same as or different from the color of the first region. Preferably, the first transparency is a parameter value when the first region is completely opaque, and the color of the first region is black; the second transparency is the value of the parameter at full transparency and the color of the second area is white. When the parameter value range of the transparency is 0-1, the parameter value of 1 indicates complete opacity, and the parameter value of 0 indicates complete transparency.

Since the first region of the target interactive picture has the first transparency, the first position determined by the transparency of the pixel point is the position of the first region. Certainly, the position of the first region may also be determined according to the color of the pixel point, for example, the pixel points of the first region and the second region of the target interactive picture are set to have different colors, so that the position of the first region may be determined according to the color of the pixel point. When the position of the first region is determined by the color of the pixel point, the transparency of the pixel point does not need to be concerned, that is, the transparencies of the first region and the second region can be the same or different. Determining the position of the first area according to the transparency or the color of the pixel point; the process is similar. Here, the description will be given only by taking an example of determining the position of the first region according to the transparency of the pixel point.

It is noted that if the interactive picture corresponding to the currently played video frame is the same as the interactive picture corresponding to the previously played video frame, the first position does not need to be recalculated, and the first position determined in the process of processing the previously played video frame can be reused. The first position may be a coordinate or a region. When the first position is a coordinate, step 203 specifically includes:

detecting the transparency of pixel points in the target interactive picture, and determining a first coordinate of a leftmost pixel point, a second coordinate of a rightmost pixel point, a third coordinate of a topmost pixel point and a fourth coordinate of a bottommost pixel point in the pixel points with the first transparency;

and taking the central coordinate as a first position of the area where the pixel point with the first transparency is located in the target interactive picture.

Of course, the first position may also be a coordinate at any pixel point in the first area, and step 203 specifically includes:

detecting the transparency of pixel points in a target interactive picture, and determining a plurality of pixel points with first transparency;

And 204, determining a target image area corresponding to the first position in the currently played video frame according to the equal proportion relation between the interactive picture and the video frame.

It should be noted that, according to the equal proportion relation, the second position corresponding to the first position may be determined in the currently played video frame; the second position is a position of the first position in the target interactive picture mapped in the current playing video frame. When the first position is a coordinate, the second position is also a coordinate, and the target image area may be a circular range with the coordinate indicated by the second position as a center and the preset value as a radius, but is not limited thereto. When the first position indicates a region range, the second position also indicates a region range; preferably, the relative position of the area indicated by the second position with respect to the currently played video frame is the same as the relative position of the first area indicated by the first position with respect to the entire target interactive picture. Video frames are usually rectangular, and the equal proportion relationship indicates that the aspect ratio of the interactive picture is the same as that of the video frame. Therefore, when the target interactive picture and the currently played video frame are in the same coordinate system (for example, the target interactive picture and the currently played video frame both have the lower left corner as the origin of the coordinate system, the length direction is parallel to the x axis, the width direction is parallel to the y axis, and the target interactive picture and the currently played video frame are both located in the first quadrant of the coordinate system), and the sizes of the interactive picture and the video frame are completely the same, if the coordinate of the upper right corner of the target interactive picture in the coordinate system is (4, 6); the position in the currently playing video frame indicated by the coordinates (4, 6) in the coordinate system is the upper right corner of the currently playing video frame.

Step 205, displaying preset prompting information in a target image area in the currently played video frame to prompt a user that the target image area is provided with interaction information.

In the embodiment of the invention, an interactive file corresponding to a target video is obtained; wherein, the interactive file includes: at least one interactive picture and the corresponding relation between each interactive picture and a video frame in a target video; the interactive picture is in equal proportion to the video frame. And in the playing process of the target video, determining a target interactive picture corresponding to the currently played video frame according to the corresponding relation. Detecting the transparency of pixel points in the target interactive picture, and determining a first position of a region where the pixel points with the first transparency are located in the target interactive picture; determining a target image area corresponding to a first position in a currently played video frame according to the equal proportion relation between the interactive picture and the video frame; the first position of the first area in the target interactive picture can be determined through the transparency of the pixel points; and then, by utilizing the equal proportion relation between the interactive picture and the video frame and the determined first position, the target image area corresponding to the first area can be quickly and accurately positioned. Compared with the method for directly determining the target image area in the video frame with complex content, the method is simpler. And displaying preset prompt information in a target image area in the currently played video frame to prompt a user that the target image area is provided with interactive information. The preset prompt information is directly displayed in the target image area for interaction, so that the prompt information can move along with a playing picture in the video playing process and is not limited to a fixed position. Meanwhile, the video content with the interactive information in the playing picture can be accurately locked, and the visual experience of the user is improved.

Fig. 3 is a flowchart illustrating steps of another method for prompting a video content interaction location according to an embodiment of the present invention, as shown in fig. 3, the method includes:

step 301, acquiring an interactive file corresponding to a target video.

And 302, when the target video is played to a preset time, determining a target interaction picture corresponding to the currently played video frame according to the corresponding relation.

It should be noted that the interactive file further includes: a predetermined time. And monitoring the playing time in the playing process of the target video, and when the playing time reaches the preset time and in the playing process later, executing the step of determining the target interactive picture corresponding to the currently played video frame according to the corresponding relation. For example, the duration of the target video is ten minutes, and the preset time is two minutes and thirty seconds. And in the target video playing process, the playing time starts from zero minutes and zero seconds to the end of ten seconds. And in the playing process of the target video from two minutes to thirty seconds to ten zero seconds, the step of determining the target interactive picture corresponding to the currently played video frame according to the corresponding relation is always executed.

The target interactive picture is one of at least one interactive picture in the interactive file. Playing a video frame at each playing moment, and then determining an interactive picture corresponding to the video frame played at the playing moment, namely a target interactive picture, according to the played video frame and the corresponding relation. Therefore, in the process of playing the target video, one target interactive picture can be determined for each playing time. Preferably, the target interactive pictures determined at the adjacent playing time points can be the same or different.

Step 303, determining a target image area in the currently played video frame according to the position of the first area in the target interactive picture.

Step 304, displaying preset prompting information in a target image area in the currently played video frame to prompt a user that the target image area is provided with interaction information.

In the embodiment of the invention, the interactive file corresponding to the target video can be obtained; wherein, the interactive file includes: at least one interactive picture and the corresponding relation between each interactive picture and a video frame in a target video; the interactive picture is in equal proportion to the video frame. And when the target video is played to a preset moment, determining a target interactive picture corresponding to the currently played video frame according to the corresponding relation. When the target video is not played to the preset moment, the target interaction picture does not need to be determined, and therefore the preset prompt information does not need to be displayed. By setting the preset time, the time for prompting through the preset prompting information can be freely started. Determining a target image area in a currently played video frame according to the position of a first area in a target interactive picture in the target interactive picture; by utilizing the equal proportion relation between the interactive picture and the video frame, the target image area corresponding to the first area can be quickly and accurately positioned. Compared with the method for directly determining the target image area in the video frame with complex content, the method is simpler. And displaying preset prompt information in a target image area in the currently played video frame to prompt a user that the target image area is provided with interactive information. The preset prompt information is directly displayed in the target image area for interaction, so that the prompt information can move along with a playing picture in the video playing process and is not limited to a fixed position. Meanwhile, the video content with the interactive information in the playing picture can be accurately locked, and the visual experience of the user is improved.

Fig. 4 is a flowchart illustrating steps of another method for prompting a video content interaction location according to an embodiment of the present invention, where as shown in fig. 4, the method includes:

step 401, acquiring an interactive file corresponding to a target video.

And 402, in the playing process of the target video, determining a target interactive picture corresponding to the currently played video frame according to the corresponding relation.

Step 403, determining a target image area in the currently played video frame according to the position of the first area in the target interactive picture.

Step 404, displaying preset prompting information in a target image area in the currently played video frame to prompt a user that the target image area is provided with interaction information.

Step 405, determining the interaction position of the interaction instruction under the condition that the interaction instruction is received.

It should be noted that, in the process of playing the target video by the electronic terminal, the video frame of the target video is displayed by the display screen. In this process, a user clicking on the display screen will trigger an interaction command. The interactive position of the interactive instruction is the position where the user clicks in the display screen or the currently played video frame.

Step 406, determining whether the mapping position of the corresponding interaction position in the target interaction picture is located in the first region according to the equal proportion relation between the interaction picture and the video frame.

It should be noted that, if the mapping position is located in the first region of the target interactive picture, it indicates that the interactive position is located in the target image region of the currently played video frame.

The first region of the target interactive picture has a first transparency, the second region has a second transparency, and the first transparency is different from the second transparency, wherein the second region is a region of the target interactive picture except the first region. In this step, the transparency of the pixel points in the target interactive picture can be utilized to judge whether the mapping position of the corresponding interactive position in the target interactive picture is located in the first region. Specifically, step 406 includes:

determining a mapping position of a corresponding interaction position in a target interaction picture according to the equal proportion relation between the interaction picture and the video frame;

acquiring the transparency of the pixel points at the mapping positions;

when the transparency of the pixel point at the mapping position is equal to the first transparency, the mapping position corresponding to the interaction position in the target interaction picture is located in the first area.

When the transparency of the pixel point at the mapping position is equal to the second transparency, the mapping position corresponding to the interaction position in the target interaction picture is located outside the first area.

Step 407, when the mapping position corresponding to the interaction position in the target interaction picture is located in the first region, a preset operation is performed.

It should be noted that the interactive file further includes: presetting operation; the preset operation may be to pop up a prompt floating layer, execute a section of animation or play a section of video, etc.

In the embodiment of the invention, the interactive file corresponding to the target video can be obtained; wherein, the interactive file includes: at least one interactive picture and the corresponding relation between each interactive picture and a video frame in a target video; the interactive picture is in equal proportion to the video frame. And in the playing process of the target video, determining a target interactive picture corresponding to the currently played video frame according to the corresponding relation. Determining a target image area in a currently played video frame according to the position of a first area in a target interactive picture in the target interactive picture; by utilizing the equal proportion relation between the interactive picture and the video frame, the target image area corresponding to the first area can be quickly and accurately positioned. Compared with the method for directly determining the target image area in the video frame with complex content, the method is simpler. And displaying preset prompt information in a target image area in the currently played video frame to prompt a user that the target image area is provided with interactive information. The preset prompt information is directly displayed in the target image area for interaction, so that the prompt information can move along with a playing picture in the video playing process and is not limited to a fixed position. Meanwhile, the video content with the interactive information in the playing picture can be accurately locked, and the visual experience of the user is improved. After the preset prompt information is displayed, determining the interaction position of the interaction instruction under the condition that the interaction instruction is received; determining whether the mapping position of the corresponding interaction position in the target interaction picture is located in the first area or not according to the equal proportion relation between the interaction picture and the video frame; and when the mapping position corresponding to the interaction position in the target interaction picture is positioned in the first area, executing preset operation. Thereby enabling user interaction with the video content.

In an application process of another method for prompting a video content interaction position provided by the embodiment of the invention, an interaction picture sequence is generated in advance according to a target video, wherein the interaction picture sequence is specifically a mask sequence, the mask sequence in the following whole description process refers to the interaction picture sequence, and the corresponding mask refers to an interaction picture; the generated mask sequence satisfies the following requirements:

first, each mask is used to represent the location of a person or object identified at a particular time in the target video.

Second, each mask size is proportional to the video frame, and the proportional relationship is 1: 1, the color in the mask is only one of black.

Third, a first area of the mask corresponding to the identified person or item of the video frame is filled with black, while the other portions are all filled with transparent pixels.

Fourth, the number of masks in a mask sequence can be determined from the scene. If the identified item or character is relatively immobile, the number of masks in the mask sequence may be reduced appropriately; if the identified item or character is moving rapidly, the number of masks in the mask sequence may be increased appropriately. The former case recommends 5 masks per second, the latter case recommends 15 masks per second.

Adding a timestamp for each mask, and establishing a corresponding relation between each mask and timestamps of a plurality of video frames in the target video;

setting the interaction starting time and the event description of the interaction operation, specifically setting according to the requirement, such as popping up a prompt floating layer, executing a section of animation or playing a section of video and the like.

And finally, packaging the mask sequence, the corresponding relation, the interaction starting time and the event description of the interaction operation into an interaction file in a JSON (JavaScript Object Notation) or XML (Extensible Markup Language) format, storing the interaction file in a network server, and generating a storage address of the interaction file in the network server.

The method for prompting the video content interaction position comprises the following steps:

step 1, when the electronic terminal acquires the target video, the electronic terminal simultaneously acquires the storage address.

And 2, downloading the interactive file from the Internet server according to the storage address and storing the interactive file into a local storage.

And 3, monitoring a target video playing progress changing event, checking whether the current playing time reaches or exceeds the interaction starting time in the interaction file when the target video playing progress is changed, if not, repeatedly executing the step 3, and if so, executing the step 4.

And 4, reading the mask A corresponding to the currently played video frame from the mask sequence according to the current playing time.

And step 5, determining a left boundary value leftSide, a right boundary value rightSide, an upper boundary value topSide and a lower boundary value bottomSide of the first area in the mask A. The method of determining each side boundary value is similar, and only the process of determining the left side boundary value will be described herein. Reading the color of each pixel point in the first row from left to right, if the color is transparent, continuing to search the next pixel point in the row until one pixel point is found, wherein the pixel color is black, recording the position leftA of the black pixel in the row, simultaneously setting leftSide to leftA, then ending the row search, and continuing to search the next row. If the second row finds that the black pixel position is leftB, the sizes of leftSide and leftB are compared, if the leftB is smaller than the leftSide, the value of the leftSide is updated, and the leftSide is set as leftB. Repeating the above operations can obtain the leftSide boundary value leftSide of the first region.

Step 6, determining the position (centerX, centerY) of the center point of the first area on the mask according to the side boundary values; wherein centerX ═ leftSide + (rightSide-leftSide)/2; centreyy ═ topSide + (bottside-topSide)/2.

And 7, drawing a prompt animation at the central point of the current playing video frame based on the position (centerX, centerY). (e.g., red blinking effect). When the playing progress is changed, steps 4 to 7 are repeatedly performed. If the obtained mask is the same as the current mask, the marker position is not changed at the time point, and the refreshing is carried out to reduce the processing and improve the performance.

And 8, acquiring the specific position clicked on the screen by the user when the user clicks the screen, and setting the position as (pointX, pointY). Reading the color of the point from the mask at the moment, if the point is transparent, indicating that the user does not click the identified person or object, and at the moment, executing a preset event is not needed; if the point is black, it indicates that the user clicks the identified person or object, and a preset event needs to be read from the interactive description file and executed.

According to the embodiment of the invention, the position of the first area in the target mask is easily determined by utilizing the characteristic of monotonous mask color. And then directly determining a target image area in the currently played video frame according to the relation between the mask and the corresponding video frame. Compared with the method for directly determining the target image area in the video frame, the method is simpler. In addition, preset prompt information is directly added to the target image area for interaction, so that the prompt information can move along with a playing picture in the video playing process and is not limited to a fixed position. Meanwhile, the video content with the interactive information in the playing picture can be accurately locked, and the visual experience of the user is improved.
