Description
Technical Field
The invention relates to the technical field of image recording and broadcasting, in particular to a method, a device, equipment and a storage medium for displaying animation special effects.
Background
There are a large number of display devices on the market today, for example, the display device is a recording and broadcasting host of an ARM (Advanced RISC Machines) platform architecture. These recording and broadcasting hosts generally have a plurality of recording and broadcasting channels. The recording and broadcasting host can display the corresponding field picture of the recording and broadcasting channel in a preset display mode. The situation that the field picture of one recording and broadcasting channel is switched to the field picture of the other recording and broadcasting channel to be displayed exists. The switching here may be referred to as recorded channel switching. And the recorded broadcast channel switching is realized by using a CPU in the recorded broadcast host. As shown in fig. 1, by closing the first recording and broadcasting channel a, the field picture of the first recording and broadcasting channel a displayed in full screen is exited, then the background picture C is displayed, then the second recording and broadcasting channel B is opened, and the field picture of the first recording and broadcasting channel B displayed in full screen is overlaid on the background picture, so that the switching of the recording and broadcasting channels is realized. However, with the development of application requirements, the recording and broadcasting host is required to present the live pictures of different recording and broadcasting channels, and animation special effect processing is also required to be performed on the presented live pictures, so that the pictures are more vivid and vivid, and the eyes of people are caught.
Because the recording and broadcasting host has a Central Processing Unit (CPU) but no Graphics Processing Unit (GPU), the recording and broadcasting host can only process pictures through the CPU to obtain the function of displaying animation special effects. Then, the CPU not only needs to display the animation special effect, but also needs to process various original services other than displaying the animation special effect, such as calculating load, controlling signaling interaction, and the like, so that the load that the CPU of the recording and broadcasting host can bear is increased, for example, one picture includes more than 200 ten thousand pixel points. The CPU is consumed for making software special effect on the picture. Thus, the load borne by the CPU of the recording and broadcasting host can be increased, and the CPU cannot normally support the original services except displaying the special effect of the animation.

Detailed Description
The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Aiming at the technical problems in the prior art: if the CPU in the host processes the picture special effect to make it present the animation special effect, the load that the CPU in the host can bear is increased, so that the CPU cannot normally support the original service except displaying the animation special effect. The embodiment of the invention provides a method, a device, equipment and a storage medium for displaying animation special effects, wherein in the process of switching a first channel and a second channel, the following processing is carried out on the first channel and/or the second channel according to received animation special effect information of a specified channel:
zooming and/or clipping a first picture currently displayed by a first channel to obtain a plurality of processed first target pictures, displaying the plurality of first target pictures in a preset time period, and presenting an animation special effect;
and carrying out zooming processing and/or clipping processing on a second picture currently displayed in the second channel to obtain a plurality of processed second target pictures, displaying the plurality of second target pictures in a preset time period, and presenting an animation special effect.
In the process of switching the first channel and the second channel, under the conditions of no GPU and no increase of the load of a CPU, the function of presenting the special effect of the animation is added, and the normal support of the original service by the CPU is not influenced while the special effect of the animation is presented. Therefore, the method for displaying the special effect of the animation provided by the embodiment of the invention can quickly display the special effect of the animation, improve the efficiency of displaying the special effect of the animation and ensure that the original service processed by the CPU is not influenced.
First, an application scenario of the method for displaying an animation special effect according to the embodiment of the present invention is described below. For example, one possible application scenario is that in the intelligent recording and broadcasting industry, the recording and broadcasting host computer implements the method for displaying the special effect of the animation. The recording and broadcasting host is generally a comprehensive host having functions of accessing an Analog Signal, an SDI (digital serial Interface) Signal, a TVI (Television Signal Interference), an AHD (Analog High Definition), a CVI (Visual contact Center), a CVBS (Composite Video Broadcast Signal) Signal, an HDMI (High Definition Multimedia Interface) Signal, a VGA (Video Graphics array, Video transmission standard) Signal, an IPC (IP Camera, web Camera), an audio Signal, and The like, and outputting a hard disk, a web stream, an HDMI Signal, and a VGA Signal. The method provided by the embodiment of the present invention can be applied to all hosts including CPUs, which are not exemplified herein.
The following describes embodiments of the present invention in detail with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for displaying an animated special effect according to an embodiment of the present invention. The steps of the method for displaying the animated special effect may include:
step 110, receiving a channel switching instruction for switching a first channel to a second channel, where the first channel is a currently displayed channel and the second channel is a channel to be displayed.
Taking the recording and broadcasting host as an example, assuming that a recording and broadcasting host has 4 recording and broadcasting channels, which are A, B, C, D channels respectively, and currently plays the content of the C channel in full screen, at this time, the channel switching instruction is received, and the content of the B channel needs to be displayed in full screen, then the C channel is the first channel in the embodiment of the present invention, that is, the channel currently being displayed, and the B channel is the second channel in the embodiment of the present invention, that is, the channel to be displayed.
And step 120, receiving the animation special effect information of the appointed channel.
The specific channel may include only the first channel or the second channel, and may further include the first channel and the second channel. That is, if the specified channel is a first channel, the first channel to be exited is required to be exited in an animated manner, while there is no requirement for a second channel; if the designated channel is the second channel, the second channel to be displayed is required to appear in an animation mode, and at the moment, no requirement can be made on the first channel; if the specified channel is a first channel and a second channel, the first channel to be exited is required to be exited in an animated manner, and the second channel to be displayed is required to appear in an animated manner.
The animation special effect information refers to what form of animation is presented by the pictures in the specified channel, and may be, for example, a reduced animation, an enlarged animation, or a moving animation.
For example, the animation special effect information of the specified channel received in step 120 may be information for performing a reduction process on a first picture of the specified first channel, and/or information for performing an enlargement process on a second picture of the specified second channel.
For another example, the animation special effect information of the specified channel received in step 120 may be movement information that specifies that the first picture of the first channel moves from a first direction to a second direction, and/or movement information that specifies that the second picture of the second channel moves from a third direction to a fourth direction, where the first direction is opposite to the second direction, the third direction is opposite to the fourth direction, and the first direction and the third direction may be the same or different. For example, the first direction is to the left, the second direction is to the right, the third direction is to the right, and the fourth direction is to the left; for another example, the first direction is upward, the second direction is downward, the third direction is upward, and the fourth direction is downward.
In the two examples, if the scheme is "and", the first channel and the second channel both receive the specified animation special effect information, and then perform corresponding processing, and if the scheme is "or", only the first channel or the second channel receives the specified animation special effect information, and only the channel receiving the specified information then performs corresponding processing. It is only listed here as a few possible cases, and in practical applications, there may be many implementations, such as from bottom left to top right, from top right to bottom left, and so on, and any direction that can be applied to the embodiments of the present invention belongs to the protection scope of the embodiments of the present invention, and this is not an example.
The approach for acquiring the first picture and/or the second picture may have a plurality of implementation manners:
one possible implementation manner is that a user uploads a first picture and/or a second picture to the device, and according to the first picture and/or the second picture uploaded by the user, the first picture currently displayed in the first channel and/or the second picture currently displayed in the second channel can be obtained.
Another possible implementation manner is that the recording and playing device directly acquires a first picture from the first channel and/or a second picture from the second channel; therefore, the first picture currently displayed by the first channel and/or the second picture currently displayed by the second channel can be directly acquired.
The above are only two possible implementation manners, and the embodiment of the present invention does not limit the manner of acquiring the first picture and/or the second picture, and any implementation manner that can acquire the first picture of the first channel and/or the second picture of the second channel may be applied to the present application.
In order to present the animation special effect, the first target picture and/or the second target picture need to be sequentially displayed within a preset time period, and the preset time period can be reasonably set as required, such as 1 second, 2 seconds, 5 seconds, and the like. And displaying a plurality of pictures in sequence within a preset time period to present the special effect of the animation. For example, 30 target pictures can be displayed within 1 second, so that an animated special effect is realized.
In the process of switching the first channel and the second channel, under the conditions of no GPU and no increase of the load of a CPU, the function of presenting the special effect of the animation is added, and the normal support of the original service by the CPU is not influenced while the special effect of the animation is presented. Therefore, the method for displaying the special effect of the animation provided by the embodiment of the invention can quickly display the special effect of the animation, improve the efficiency of displaying the special effect of the animation and ensure that the original service processed by the CPU is not influenced.
In the embodiment of the present invention, although the sources of the first picture and the second picture are different, that is, one picture is from the currently displayed first channel and one picture is from the switched second channel to be displayed, the processing manner for generating the animation special effect is the same, and the specific implementation manner is described below by taking the second picture of the second channel to be displayed as an example.
In the embodiment shown in fig. 1, assuming that the second picture needs to be scaled in step 103, the step of scaling the second picture according to the animation special effect information to obtain a plurality of processed second target pictures includes:
01) and setting the second picture as a second picture to be processed with a preset size requirement. The size of the second to-be-processed picture may be the same as, or larger than, or smaller than the size of the second picture. See fig. 3, which is a schematic diagram of a corresponding relationship between the second picture and the second picture to be processed. In this embodiment, the width and height of the second picture are 1920 × 1080, and the width and height of the second to-be-processed picture are 1280 × 720, which are smaller than the second picture.
02) The width and height of the N second target pictures are calculated, and refer to fig. 4, which is a schematic diagram of a plurality of second target pictures calculated by applying the embodiment of the present invention. The calculation process specifically comprises the following steps:
the width and height of the 1 st second target picture are: W/N, H/N,
the width and height of the 2 nd second target picture are: W/Nx 2, H/Nx 2,
……,
the width and height of the (N-2) th second target picture are as follows: W/Nx (N-2), H/Nx (N-2),
the width and height of the (N-1) th second target picture are as follows: W/N (N-1), H/N (N-1),
the width and height of the Nth second target picture are as follows: W/NXN, H/NXN.
W is the width of the nth second target picture, H is the height of the nth second target picture, N is the number of times calculated within a preset time period, and N is a natural number and can be set according to actual requirements. Optionally, N may take on values of 25, 30, 40, 60, etc.
The step of calculating the width and height of the N second target pictures as a result of processing the second picture as the processing object is the same as the step of calculating the width and height of the N first target pictures as a result of processing the first picture as the processing object, except that the processing object and the obtaining result are different. Specifically, in the embodiment shown in fig. 1, assuming that the first picture needs to be scaled in step 103, the first picture is scaled according to the animation special effect information, and the step of obtaining a plurality of processed first target pictures is to set the first picture as a first to-be-processed picture with a preset size requirement, and calculate the widths and heights of the N first target pictures.
In order to facilitate understanding of the implementation process of calculating the width and height of the N first target pictures by using the first picture in the present application, a specific implementation manner is described below by taking the currently displayed first picture of the first channel as an example.
01) And setting the first picture as a first picture to be processed with a preset size requirement. The size of the first to-be-processed picture may be the same as, larger than, or smaller than the size of the first picture. In this embodiment, the width and height of the first picture may be 1920 × 1080, and the width and height of the first to-be-processed picture may be 1280 × 720, which is smaller than the first picture.
02) And calculating the width and height of the N first target pictures. The calculation process specifically comprises the following steps:
