Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
Fig. 1 is a schematic diagram illustrating a system architecture of an exemplary application environment to which a special effect display method and apparatus for a live broadcast room according to an embodiment of the present invention may be applied.
As shown in fig. 1, the system architecture 100 may include a plurality of terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 serves as a medium for providing communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wireless communication links and the like.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation. For example, server 105 may be a server cluster comprised of multiple servers, or the like.
The terminal devices 101, 102, 103 may be various electronic devices having a processor including, but not limited to, smart phones, tablet computers, portable computers, and the like. The server 105 may be a server that provides various services. For example, the terminal devices 101, 102, 103 may obtain, via the processor, the actual pixel size of the special effect, the screen resolution of the terminal device used to display the special effect, and the display state of the terminal device. The server 105 may determine a scaling of the special effect in the display state according to the actual pixel size of the special effect and the screen resolution of the terminal device, and adjust the display size of the special effect according to the scaling of the special effect. The terminal devices 101, 102, 103 may also complete the whole process from acquiring the actual pixel size of the special effect to displaying the special effect through the processor.
In some related embodiments, the display size of the special effect when the special effect is played in the live broadcast room is the actual pixel size of the special effect, and this method may result in that the display size of the special effect is larger on a low-resolution terminal device, while the display size of the special effect is smaller on a high-resolution terminal device, which may cause the user experience of different devices to be inconsistent. The display is directly performed according to the actual pixel size of the special effect, and the problem that the display size of the special effect is adapted on the same terminal device without watching live broadcast according to the state of a horizontal screen or a vertical screen, and partial display of the special effect is blocked, deformed and the like can be caused. Under the condition of no adaptive equipment resolution and horizontal and vertical screen states, further business expansion is not facilitated according to the position or size of the special effect.
In practical application, the higher the screen resolution, the smaller the special effect window is displayed. As shown in fig. 2, the difference in display size of the same effect on devices of different screen resolutions can be seen. The screen resolution of the terminal device 201 is low (e.g., 1600 × 900), the screen resolution of the terminal device 202 is high (e.g., 2248 × 1080), if the display is performed according to the actual pixel size of the special effect, the display size of the special effect 203 is large on the live interface of the terminal device 201, and the display size of the special effect 204 is small on the live interface of the terminal device 202, which results in inconsistent user experience of the two devices.
In view of the above problem, the present exemplary embodiment first provides a special effect display method for a live broadcast room. Referring to fig. 3, the method for displaying special effects in a live broadcast room may include the following steps:
and S310, acquiring the actual pixel size of the special effect.
In this exemplary embodiment, the actual pixel size of the special effect refers to the absolute width and height pixel values of the special effect. The actual pixel sizes of different special effects are also different, and can be specifically set according to the shape, the style, the playing mode and the like of the special effects.
And S320, acquiring the screen resolution of the terminal equipment for displaying the special effect and the display state of the terminal equipment.
In the present exemplary embodiment, the screen resolution for the terminal device and the display state of the terminal device may be acquired by the server or the processor. The screen resolutions of different configurations of terminal devices are different, for example, some low-end devices have a low screen resolution (e.g. 1600 × 900), and some high-end devices have a high screen resolution (e.g. 2248 × 1080).
The display state of the terminal device includes a vertical screen state and a horizontal screen state for common mobile devices. If the user views the screen through some equipment which cannot be turned over, such as a computer, the user only usually has a landscape state.
And S330, determining the scaling of the special effect in the display state according to the actual pixel size of the special effect and the screen resolution of the terminal equipment.
After the actual pixel size of the special effect and the screen resolution of the terminal device are obtained, the scaling of the special effect can be determined according to different terminal devices or parameters of different display states of the same terminal device. In determining the scaling of the special effect, the resolution of the short side of the terminal device is typically used as a reference.
And S340, adjusting the display size of the special effect according to the scaling of the special effect, and displaying the adjusted special effect at a preset position on the terminal equipment.
After the scaling of the special effect is determined, the display size of the special effect is adjusted according to the scaling of the special effect, for example, for a terminal device with lower screen resolution, the display size of the special effect is reduced; for terminal equipment with higher screen resolution, the display size of the special effect is increased, so that the special effects on different equipment are displayed according to the same screen proportion, and the sizes of the special effects seen by users are the same.
The display position of the special effect can be set differently according to the actual situation, for example, some special effects are displayed in the middle of the screen, some special effects are displayed below the screen, some special effects need to be paved on the whole screen, and the setting is carried out according to the playing effect required by different special effects.
After the adaptation of the special effects is performed by the above method, as shown in fig. 4, on terminal devices 401 with different screen resolutions, the special effects 402 are all displayed according to the same screen scale, and the visual effects viewed by the user are the same. As shown in fig. 5, the same terminal device dynamically scales the display size of the special effect according to the horizontal and vertical screen states, and when the terminal device switches from the vertical screen state 501 to the horizontal screen state 502, the special effect 503 in the vertical screen state 501 is also adjusted to the special effect 504 in the horizontal screen state 502.
In the method for displaying the special effect in the live broadcast room in the exemplary embodiment of the present disclosure, by providing a method for displaying the special effect in the live broadcast room by adapting the terminal device, the display size of the special effect can be automatically adapted on the terminal devices with different screen resolutions or in different display states of the same terminal device. On one hand, the special effect can be displayed on the screen according to the same display proportion on the terminal equipment with different screen resolutions, so that the watching experience of users using different equipment is consistent; on the other hand, the special effect can be completely and fully played and displayed in the horizontal and vertical screen display state of the same terminal device, the display effect of the special effect in a live broadcast room is improved, and therefore the live broadcast watching experience of a user is further improved.
Next, the above steps of the present exemplary embodiment will be described in more detail with reference to fig. 6 to 12.
In step S330, as shown in fig. 6, determining a scaling of the special effect in the display state according to the actual pixel size of the special effect and the screen resolution of the terminal device may specifically include the following steps:
step S610, determining a first screen pixel value and a second screen pixel value of the terminal device according to the screen resolution of the terminal device, wherein the first screen pixel value is smaller than the second screen pixel value.
In this exemplary embodiment, the first screen pixel value of the terminal device refers to a pixel value of a short side of the terminal device screen, and the second screen pixel value of the terminal device refers to a pixel value of a long side of the terminal device screen. For example, the screen resolution of the terminal device is 2248 × 1080, the first screen pixel value is 1080, and the second screen pixel value is 2248.
And S620, determining a scaling factor from the actual pixel size of the special effect according to the display state of the terminal equipment.
In the present exemplary embodiment, the actual pixel size of the special effect, that is, the absolute width and height pixel values of the special effect.
In step S620, as shown in fig. 7, determining a scaling factor from the actual pixel size of the special effect according to the display state of the terminal device may specifically include the following steps:
step S710, if the display state of the terminal device is a vertical screen state, determining a first actual pixel value of the special effect in the horizontal direction as a scaling factor.
The first actual pixel value of the effect in the horizontal direction is the pixel value of the effect in the horizontal direction. If the current display state of the terminal equipment is a vertical screen state, the first actual pixel value of the special effect is used as a scaling factor when the scaling is calculated, namely the width of the special effect is used as the scaling factor.
And S720, if the display state of the terminal equipment is a horizontal screen state, determining a second actual pixel value of the special effect in the vertical direction as a scaling factor.
The second actual pixel value of the special effect in the vertical direction is the pixel value of the special effect in the vertical direction. If the current display state of the terminal device is the landscape state, the second actual pixel value of the special effect is used as the scaling factor when the scaling is calculated, namely the height of the special effect is used as the scaling factor.
And S630, taking the first screen pixel value as a scaling reference value, and obtaining the scaling of the special effect according to the ratio of the scaling reference value to the scaling factor.
In calculating the scaling, the pixel value of the short side of the terminal device is used as the scaling reference value, that is, the first screen pixel value is used as the scaling reference value.
For the vertical screen state, the scaling calculation method comprises the following steps: a first actual pixel value of the special effect/a first screen pixel value of the terminal device; for the landscape state, the scaling calculation method is as follows: second actual pixel values of the special effect/first screen pixel values of the terminal device.
In step S340, as shown in fig. 8, adjusting the display size of the special effect according to the scaling of the special effect, and displaying the adjusted special effect at a preset position on the terminal device, specifically, the method may include the following steps:
and step S810, obtaining the target pixel size of the special effect according to the scaling of the special effect and the actual pixel size of the special effect.
After the scaling of the special effect is obtained, according to the product of the scaling and a first actual pixel value and a second actual pixel value in the actual pixel size, a first target pixel size and a second target pixel size in the target pixel size are respectively obtained, and therefore the size of the target pixel size of the special effect is determined.
And S820, drawing a special effect display window at a preset position on the terminal equipment according to the target pixel size of the special effect, and displaying the special effect on the terminal equipment through the special effect display window.
The display window can be drawn by using a glViewPort function in OpenG L (OpenGraphics L library), and the viewport is set to occupy the whole pixel rectangle of the display window under the default condition, and the size of the display window is the same as the size of the viewport, so the transformation can be realized by using the glViewPort function, a pixel rectangle is defined in the display window, and the special effect image is mapped to the rectangle finally.
Next, a method of acquiring an actual pixel size of a special effect will be described in detail with reference to fig. 9 and 10.
In step S310, as shown in fig. 9, acquiring an actual pixel size of the special effect may specifically include the following steps:
step S910, a multimedia file with a special effect is obtained, and metadata of the special effect is obtained from the multimedia file.
And S920, acquiring the actual pixel size of the special effect from the metadata of the special effect.
After the multimedia file with the gift special effect is downloaded to the local through the server, the metadata of the special effect in the multimedia file can be read, and therefore the actual pixel size of the special effect is obtained. Metadata (Metadata), also called intermediary data and relay data, is data (data about data) describing data, and is mainly information describing data attributes, and Metadata of a special effect includes information such as format, size, and size of the special effect.
In this exemplary embodiment, the obtaining of the actual pixel size of the special effect is first obtained through metadata in the multimedia file, and if the reading of the actual pixel size of the multimedia file fails, the actual pixel size of the special effect may be obtained through a special effect video frame.
In step S310, as shown in fig. 10, acquiring an actual pixel size of the special effect may further include the following steps:
step S1010, a video image of any frame in the special effect video of the special effect is obtained.
And S1020, acquiring the video pixel size of the video image, and acquiring the actual pixel size of the special effect according to the video pixel size.
The special effect video is composed of special effect video images of one frame, the video image of any frame in the special effect video is obtained, and the pixel size of the video image is read, so that the actual pixel size of the special effect can be obtained.
By the method, the display process of the special effect under different terminal devices and different display states can be completed. After the display size and the display position of the special effect in different terminal devices and different display states are determined, service expansion can be performed according to the display size and the display position of the special effect, for example, an avatar, an ID, a file of a user or the like can be displayed at a specified position of the special effect.
As shown in fig. 11, the special effect display method for a live broadcast room according to this exemplary embodiment may further include the following steps:
step S1110, determining the display size and the display position of the additional display control corresponding to the special effect according to the display size and the display position of the special effect on the terminal equipment.
The additional display control corresponding to the special effect refers to display controls related to the special effect position, such as the head portrait, the ID or the file of a broadcaster or a gift giver, wherein the head portrait and the ID in the additional display control need to be displayed at the specified position of the special effect, and the file can be directly displayed at the specified position or can be typed out on a screen word by word according to the display position.
And step S1120, displaying the additional display control on the terminal equipment according to the display size and the display position of the additional display control while displaying the special effect on the terminal equipment.
When the terminal equipment displays the special effects, if some special effects have the display requirements of the additional display control, the special effects are displayed at the specified positions of the special effects according to the display size and the display position of the additional display control. As shown in fig. 12, on a special effect 1202 of the terminal device 1201, an avatar 1203 of a gift giver and a case 1204 related to the gift are displayed.
If the method that the display is directly carried out according to the actual pixel size of the special effect in the related embodiment is used, the position of the additional display control of the special effect cannot be controlled and cannot be displayed at the specified position due to the large difference of the display sizes of the special effects of different devices.
It can be seen that, in the special-effect display method for the live broadcast room in the present exemplary embodiment, since the display size and the position of the same special effect can be determined on different terminal devices, the application of the screen space can be better controlled, service expansion in aspects such as additional display controls and the like is facilitated, better experience is brought to the user, and thus, consumption of the user is further stimulated.
It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
Furthermore, the disclosure also provides a special effect display device of the live broadcast room. Referring to fig. 13, the live room special effect display apparatus may include an actual pixel obtaining module 1310, a screen state obtaining module 1320, a scaling module 1330, and a display size adjusting module 1340.
