Detailed ways

In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the following further describes the embodiments of the present disclosure in detail with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of an implementation environment involved in a method for generating an animation file provided by an embodiment of the present disclosure. As shown in FIG. 1, the implementation environment may include a terminal 110, which may be a computer, a notebook computer, or a smart phone, etc., and FIG. 1 takes the terminal 110 as a computer as an example for illustration.

For example, an animation file generating device may be installed in the terminal 110, and the animation file generating device may include an animation data processing module and an encoding export file module. Among them, the animation data processing module can obtain the target parameters and target pictures (also called animation materials) input by the developer to generate the animation files, and can take corresponding methods to perform the target parameters according to the type of the input target parameters. Processing to obtain the animation data in the target format, and the generated animation data and the target picture can be sent to the encoding export file module. The encoding export file module can convert the received animation data into a file in the target format, and compress and pack the file in the target format and the target picture together to generate an animation file in the target format for playback of the animation file that supports the target format Player to play.

Among them, the target format refers to the format in which the animation file is played. Optionally, in the embodiments of the present disclosure, the target format is a scalable vector graphics animation (Scalable Vector Graphics Animation, SVGA) format compatible with different system platforms at the same time as an example for description.

FIG. 2 is a flowchart of a method for generating an animation file provided by an embodiment of the present disclosure, and the method may be applied to the terminal 110 shown in FIG. 1. As shown in Figure 2, the method may include:

Step 201: Obtain target parameters and target pictures used to generate an animation file.

In the embodiment of the present disclosure, when an animation file needs to be developed, the developer can input the target parameter and target picture for generating the animation file in the terminal, and accordingly, the terminal can obtain the target parameter and target picture. Wherein, the target parameter refers to a parameter related to the animation file to be generated (such as playing duration and playing effect), and the target picture may include one or more pictures.

Step 202: Generate animation data in the target format based on the target parameters.

Wherein, the animation file generally includes multiple frames of pictures, and the animation data can be used to indicate the playback form of the target picture in the multiple frames of pictures. In the embodiment of the present disclosure, the terminal may encapsulate the acquired target parameters according to the encapsulation standard of the target format to generate animation data in the target format. Optionally, the target format may be the SVGA format.

Step 203: Generate an animation file in the target format according to the animation data and the target picture.

In the embodiment of the present disclosure, after the terminal generates the animation data in the target format, it can continue to write the animation data and the target picture into the same file according to the file standard of the target format and compress and pack them to generate the animation file in the target format.

In summary, the embodiments of the present disclosure provide a method for generating an animation file. Wherein, the terminal can obtain the target parameter and target picture used to generate the animation file, can generate the animation data in the target format based on the target parameter, and can generate the animation file according to the animation data and the target picture. Since the terminal can automatically generate an animation file based on the acquired target parameters and target pictures, compared with the related art that the terminal can only receive the animation file pre-designed by the designer, the animation file generation method is more flexible. Correspondingly, the content and style of the generated animation file will be richer.

In the following, taking the target format as the SVGA format as an example, the method for generating the animation file provided by the embodiment of the present disclosure is introduced. FIG. 3 is a flowchart of another method for generating an animation file provided by an embodiment of the present disclosure, which can be applied to the terminal 110 shown in FIG. 1. As shown in Figure 3, the method may include:

Step 301: Obtain target parameters and target pictures for generating an animation file.

In the embodiment of the present disclosure, when an animation file needs to be developed, the developer can input the target parameter and target picture for generating the animation file in the terminal, and accordingly, the terminal can obtain the target parameter and target picture. Wherein, the target parameter refers to a parameter related to the animation file to be generated, and the target picture may include one or more pictures.

Since the animation file refers to a file that the target picture can be played dynamically, the animation file generally includes multiple frames, and the target picture is spliced together in the playback state of each frame to form the animation file. Correspondingly, the target parameter used to generate the animation file may include multiple element state values, and each element state value may be used to indicate the playback state of the target picture in one frame (that is, the target parameter may include complete animation data). For example, the element state value may include at least one of the position of the target picture in a frame of the picture, the degree of transparency, the angle of rotation, and the degree of zoom. Alternatively, the target parameter may not include multiple element state values, but only include related parameters that can obtain multiple element state values. For example, the target parameter may include playback duration, playback effect, and frame rate, or the target parameter may include playback duration, playback effect, frame rate, and playback track.

Among them, the playback duration refers to the duration of the playback of the animation file, and the playback effect refers to the playback form of the animation file. For example, the playback effect can be jitter (that is, the target picture is constantly displayed during the playback time), and translation (that is, the target picture Continuously during the playback time), zoom (that is, the target image is continuously zoomed during the playback time), spring effect (that is, the target image is continuously stretched and compressed during the playback time), or gradient (that is, the transparency or color of the target image changes during the playback time) )Wait. The frame rate refers to the frequency of continuous appearance of the target image during the playback time. The playback track refers to the playback position of the target picture within the playback duration. Optionally, the target parameter may also include the picture size (size) of the target picture.

Optionally, for each parameter, multiple optional items may be pre-configured in the terminal. Correspondingly, the target parameter obtained by the terminal may be a parameter input by the user for the selection operation of the multiple optional items. Or, the target parameter acquired by the terminal may be a parameter input by the user in real time.

For example, the terminal may be pre-configured with a variety of candidate playback effects, and the playback effects obtained by the terminal may be determined by the terminal according to a developer's selection operation for the pre-configured multiple candidate playback effects. Or, the playback effect may be determined by the terminal according to the playback effect input by the developer.

For another example, the playing track may be determined according to a touch operation performed by the user on the drawing interface, or a variety of candidate tracks may be pre-configured in the terminal, and the playing track may be based on the user's selection operation for at least one candidate playing track Or, the playing track may be the contour of the target object obtained by recognizing the target object. Assuming that the target object is a person, the contour may be a face contour obtained by recognizing the face. Of course, the embodiments of the present disclosure are not limited to the recognition of human face contours.

Step 302: Generate animation data in the target format based on the target parameters.

In the embodiment of the present disclosure, the animation data can be used to indicate the playback form of the target picture in the multi-frame picture, that is, it can be used to indicate the playback effect of the target picture during the playback time.

It should be noted that the operation of generating animation data may be different due to different target parameters. For example, when the target parameter includes multiple element state values, the terminal may directly encapsulate the multiple element state values and other parameters based on the packaging standard of the target format to generate animation data in the target format. When the target parameter does not include multiple element state values, the terminal needs to first determine the multiple element state values based on the target parameter, and then encapsulate the multiple element state values and other parameters to generate animation data in the target format. Therefore, after acquiring the target parameter, the terminal can select a corresponding processing method to process the target parameter according to the target parameter, so as to generate animation data in the target format.

Optionally, the embodiment of the present disclosure introduces the method for generating animation data in the following ways:

An optional implementation manner: the target parameter includes the playback duration and multiple element state values. That is, what the developer inputs to the terminal can be the animation data of the entire animation interval. Correspondingly, the terminal can directly encapsulate the playback duration and multiple element state values according to the encapsulation standard of the target format, thereby generating animation data in the target format. It should be noted that, before encapsulation, the terminal may first analyze the playback status of each frame according to multiple element status values frame by frame.

By directly obtaining multiple element state values, on the one hand, since the terminal no longer needs to calculate and determine multiple element state values based on target parameters, it can effectively reduce terminal processing resources and save terminal power consumption. On the other hand, because multiple element state values can be specified by the developer, the generated animation file is not limited to the existing playback effects, that is, the method of generating the animation file is more flexible, and the content and style of the generated animation file More abundant.

Another optional implementation manner: the target parameter may include playback duration, frame rate, and playback effect. Correspondingly, FIG. 4 is a flowchart of a method for generating animation data provided by an embodiment of the present disclosure. As shown in Figure 4, the method may include:

Step 3021A: Determine multiple element state values according to the playback duration, frame rate and playback effect.

In the embodiment of the present disclosure, the terminal may first multiply the playback duration (duration) and the frame rate (frame rate) to obtain the total frame count (frame count) of the pictures included in the animation file. That is, the total number of frames can satisfy the following formula: frame count=duration*frame rate formula (1).

For example, assuming that the playback duration acquired by the terminal is 3 seconds (s) and the frame rate is 15 hertz (Hz), the total frame count calculated by the terminal according to formula (1) is: frame count = duration * frame rate =3*15=45.

Then, the terminal can determine multiple element state values based on the total number of frames and the playback effect. For example, for each target picture, the terminal may first fill in the specific data of the target picture in all frames according to the playback effect, and the specific data refers to the playback state of the target picture. Then, the terminal can use a pre-configured animation interface to create a corresponding animation object according to the playback effect, and cycle to play the created animation object within the playback duration according to the total number of frames and the frame rate. For example, assuming that the total number of frames is n and the frame rate is f, the terminal can execute n cycles, each cycle incrementing by 1/f second (s). In addition, the terminal can use a pre-configured interpolation algorithm to determine multiple element state values during each loop playback.

Optionally, the animation interface may be a built-in animation interface of the terminal system, or may be an interface that the terminal receives when developing an animation file by a developer. In the same way, the interpolation algorithm can be an algorithm that comes with the terminal system, or it can be an algorithm written by a developer when developing an animation file.

Step 3022A: According to the encapsulation standard of the target format, encapsulate the playback duration and multiple element state values to generate animation data in the target format.

For example, assuming that the target format is the SVGA format, after the terminal determines multiple element state values based on the target parameters, it can encapsulate the playback duration and multiple element state values according to the encapsulation standard of the SVGA format (also called a combination ) To get the animation data in SVGA format.

Since the terminal can automatically determine the status of multiple elements based on target parameters such as playback effect, duration, and frame rate, by only inputting parameters such as playback effect, duration, and frame rate, the efficiency of generating animation files can be improved and the work of developers can be reduced. , To ensure the reliability of the generated animation files.

Yet another optional implementation manner: the target parameter may include playback duration, frame rate, playback effect, and playback track. Correspondingly, FIG. 5 is a flowchart of another method for generating animation data provided by an embodiment of the present disclosure. As shown in Figure 5, the method may include:

Step 3021B: Determine at least one playback position of the target picture according to the playback track.

In the embodiment of the present disclosure, the terminal may first determine a plurality of sampling points according to the acquired playback trajectory, and then, the terminal may determine the position of at least one target sampling point selected from the plurality of sampling points as at least the position of the target picture A playback position. Wherein, the distance between every two adjacent target sampling points is greater than the distance threshold. That is, the terminal may first tile the target picture according to the determined playback track, and every two adjacent target pictures obtained by the tile do not overlap.

Optionally, the spacing threshold may be a fixed value pre-configured in the terminal, or the spacing threshold may be a parameter input by the developer received by the terminal, or the spacing threshold may be the size of the target picture.

For example, referring to Figure 6, assuming that the size of the target picture is a rectangle Q of m*n, the playback trajectory acquired by the terminal is a star shown in Figure 6, and the star trajectory occupies a rectangle P of M*N. The spacing threshold is m/2-1. The terminal may first determine multiple sampling points a0 to an according to the star-shaped trajectory, and determine the locations of multiple adjacent target sampling points with a spacing greater than m/2-1 as multiple playback positions of the target picture. For example, for each sampling point, the terminal can use the sampling point as the midpoint to determine a rectangle Qi of size m*n, and determine the midpoint of a rectangle that is adjacent to the sampling point and has no intersection at all. It is a target sampling point. Correspondingly, the distance between every two adjacent target sampling points is m/2, which is greater than the distance threshold. Then, the terminal may determine the determined positions of the multiple target sampling points as the playback position of the target picture. In addition, after multiple rectangles Qi are determined by the target sampling points, the terminal can delete the part where the rectangle Qi and the rectangle P intersect, so that multiple playback positions of the target picture covering the entire star track can be obtained.

Step 3022B: Multiply the playback duration and the frame rate to obtain the total number of frames included in the animation file.

The method for implementing this step can refer to the method of calculating the total number of frames in step 3021A above.

Step 3023B: Determine multiple element state values based on the playback effect, at least one playback position of the target picture, and the total number of frames.

The implementation of this step can also refer to the method of determining multiple element state values in step 3021A. The difference is that this method also needs to determine multiple element state values according to at least one playback position determined by the playback track, that is, the step is completed. The obtained multiple element state values are related to the playback track.

Step 3024B: According to the encapsulation standard of the target format, encapsulate the playback duration and multiple element state values to generate animation data in the target format.

For the implementation method of this step, reference may be made to the method of step 3022A above, which will not be repeated here.

By determining the state values of multiple elements based on the playback track, developers can design the playback style of animation files by themselves, that is, on the premise of improving the efficiency of generating animation files, the flexibility of generating animation files is further improved, and the interest of the product is improved. Sex and user experience.

Step 303: Encode the animation data according to the file standard of the SVGA format.

In the embodiment of the present disclosure, the target format may be the SVGA format. Accordingly, after the terminal obtains the animation data, it can continue to encode the animation data according to the SVGA format file standard, that is, encode the animation data into a SVGA format file form.

Optionally, the file standard of the SVGA format may include version 1.0 and version 2.0. The file standard of the SVGA format of version 1.0 is a json format file, and the file standard of the SVGA format of version 2.0 is a google protobuf format file.

Step 304: Compress the encoded animation data and the target picture to obtain an animation file in SVGA format.

In the embodiment of the present disclosure, the terminal may continue to write the encoded animation data and the target picture into the same file, and compress and pack the file, thereby generating an animation file in the SVGA format.

By way of example, the following takes the gifting scene of the animation gift in the live broadcast client as an example to introduce the animation file application generated by the animation file generation method provided by the embodiment of the present disclosure.

For example, referring to Figure 7, suppose the first client is playing a live video recorded by user XX of the second client, and the “gift” option, “personality” option, and “package” option are displayed at the bottom of the display interface of the first client. The "personality" option is an animation gift generation option. When the first client detects that the user clicks the "personality" option, the first client can detect the animation gift generation instruction. At this time, as shown in Figure 7, the display interface of the first client can display a painting mask H1 and a gift bar G1 containing multiple candidate gift pictures. The gift bar G1 includes lollipop pictures, Rose pictures, love pictures, and love letter pictures, and the logo and unit price of the gift picture can also be displayed below each candidate gift picture, such as lollipop 0.1Y, Y can be the first client’s The unit for setting the price of the gift picture, and the identifier of the gift picture may be a text used to describe the gift picture. Referring to Figure 7, the user selects the lollipop icon and draws a heart-shaped pattern on the painting mask H1. After the user clicks the send button, the animated gift drawn by him can be successfully sent to the second client to watch The animated gift can be played on the interface of the client of the live broadcast user. And, referring to FIG. 7, after the user draws the animation file, the display interface may also display a text prompt "10 lollipops are drawn, the total price is 1Y, and the balance is 0.7Y". For the terminal side: when the first client receives an instruction to send an animation file, it can send the received animation file to the server, and then the server will send it to other clients watching the live broadcast for display by other clients Play the animation file on the interface.

It should be noted that the sequence of steps in the method for generating animation files provided by the embodiments of the present disclosure can be adjusted appropriately, and the steps can also be increased or decreased accordingly according to the situation. For example, the above steps 303 and 304 can be executed simultaneously. Any person skilled in the art can easily think of a method of change within the technical scope disclosed in the present disclosure, which should be covered by the protection scope of the invention, and therefore will not be repeated.

In summary, the embodiments of the present disclosure provide a method for generating an animation file. Wherein, the terminal can obtain the target parameter and target picture used to generate the animation file, can generate the animation data in the target format based on the target parameter, and can generate the animation file according to the animation data and the target picture. Since the terminal can automatically generate an animation file based on the acquired target parameters and target pictures, compared with the related art that the terminal can only receive the animation file pre-designed by the designer, the animation file generation method is more flexible. Correspondingly, the content and style of the generated animation file will be richer.
