[0034] Before introducing the technical solution provided by the embodiments of the present disclosure, an exemplary description of the application scenario can be given first. The embodiments of the present disclosure can be applied to the scenario where the multimedia data stream collected by the camera device is presented on the public display device during the process of holding an event, and at least one of the multimedia data presented on the public display device includes the video stream after special effect processing. For example, if the event held is a concert, then the public display device can be a display screen placed in a preset area, and a certain multimedia data stream after special effect processing can be displayed on the display screen. The preset area can be the event holding area. If the event held is a football game, then the public display device can be a display screen placed in the football field. At the same time, a plurality of camera devices are also deployed in the event holding area, and each camera device can collect the multimedia data stream from its corresponding perspective, and a certain multimedia data stream can be presented on the public display device after special effect processing.

[0035] Figure 1 As shown in the flowchart of an information display method provided by the embodiments of the present disclosure, the embodiments of the present disclosure are applicable to the scenario where the multimedia data stream collected from the event holding area is presented on the display device deployed in the event holding area after special effect processing. This method can be executed by an information display device, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, which can be a mobile terminal, a PC or a server, etc.

[0036] As Figure 1 shown, the method of this embodiment can specifically include:

[0037] S110. Receive the first multimedia data streams sent by at least two collection devices, and send the second multimedia data stream that meets the preset conditions to the media data processing device, so as to determine the third multimedia data stream corresponding to the second multimedia data stream based on the media data processing device, where the at least two collection devices are devices deployed in the preset area for collecting the media data stream in the preset area, the second multimedia data stream is the first multimedia data stream that meets the preset conditions, and the third multimedia data stream is the video stream after special effect processing of the second multimedia data stream.

[0038] Among them, the acquisition device can be understood as a device deployed in a preset area for acquiring multimedia data streams within the preset. Optionally, the acquisition device can be a camera, a mobile terminal, or a PC. Multimedia data in a certain acquisition perspective within the preset area can be acquired in real time based on the acquisition device. In this embodiment, the acquisition device can be a handheld device, and its acquisition perspective can be controlled by the user to whom the handheld device belongs, or can be determined based on the method for determining the region of interest integrated in the acquisition device. The acquisition end of the acquisition device can rotate 340 degrees to acquire multimedia data streams from different perspectives. The method for determining the region of interest can be: acquiring multimedia data streams from different acquisition perspectives, analyzing and processing the multimedia data streams, determining the video stream with rich picture content, and using the perspective corresponding to the video stream with rich picture content as the region of interest. Correspondingly, the perspective corresponding to the region of interest is used as the acquisition perspective. The richness of the picture content can be determined based on the picture content richness analysis model or analysis method, and its specific determination method is not limited in this embodiment.

[0039] Generally, multiple acquisition devices can be deployed within the preset area to acquire multimedia data streams from corresponding acquisition perspectives based on different acquisition devices. The preset area can be a completely open area or a semi-open area. A completely open area can be understood as any square or a certain open-air area. A semi-open area can be understood as an indoor area. Optionally, the indoor area can be a sports center, etc. The preset area at least includes activity participating users and a public screen display device. The public screen display device can be a device whose presented content can be seen by activity participating users in the preset area from different perspectives. In this embodiment, the public screen display device has the following characteristics in terms of visual presentation effects: high resolution, high brightness, high contrast, rich colors, and high refresh rate. The multimedia data stream corresponding to a certain acquisition device among the multiple acquisition devices can be presented on the public screen display device. At the same time, in order to increase the interactivity among activity participating users in the preset area, the multimedia data stream after special effect processing can be presented on the public screen display device.

[0040] In this embodiment, the acquisition device can acquire the data stream in the corresponding perspective within the preset area in real time, and this data stream can be used as the first multimedia data stream. The second multimedia data stream is a certain data stream among multiple first multimedia data streams. The preset condition is a condition preset for how to determine the second multimedia data stream from multiple first multimedia data streams. That is, the first multimedia data stream that meets the preset condition is used as the second multimedia data stream.

[0041] Exemplarily, 10 camera devices (acquisition devices) are deployed inside the event hosting area, and each camera device acquires a first multimedia data stream from its corresponding perspective. If the first multimedia data stream acquired by the 5th camera device currently meets the preset conditions, then the first multimedia data stream acquired by the fifth camera device is the second multimedia data stream.

[0042] Generally, in order to improve the interactivity between the event participating users in the preset area and the public screen display device, the second multimedia data stream to be presented on the public screen display device can be processed. Optionally, the processing can be special effect processing, and the second multimedia data stream after the special effect processing is used as the third multimedia data stream. It can be understood that the third multimedia data stream is the video stream to be presented on the public screen display device, and the third multimedia data stream is the video stream after the special effect processing of the content presented in the second multimedia data stream.

[0043] In this embodiment, the second multimedia data stream can be composed of one video frame after another. Special effect processing can be performed on the users in each video frame, or special effect processing can be performed on the entire picture content of the video frame. The specific object to which the special effect is applied can be set according to the requirements in the development stage and is not limited in this embodiment.

[0044] The media data processing device can be understood as a device for performing special effect processing on the second multimedia data stream. In this embodiment, in order to solve the latency problem presented after the media data processing device performs special effect processing on the second multimedia data stream and provides feedback, the media data processing device can adopt a high-performance device. Optionally, the media data processing device selects high-performance PC hardware, high-performance GPU graphics card devices, etc., so as to meet the high computing requirements of video acquisition, special effect processing, and real-time rendering.

[0045] It should also be noted that in order to further improve the processing performance of the media data processing device, the code can be optimized, that is, the code flow is optimized to reduce unnecessary calculations and memory overhead. At the same time, a reasonable memory management mechanism can be developed so that after the third multimedia data stream after the special effect processing is fed back, the multimedia data stream can be released based on the memory management mechanism, thereby solving the problem that the system performance deteriorates due to memory leakage.

[0046] Specifically, multiple acquisition devices can be deployed within a preset area. At the same time, the multiple acquisition devices can communicate with the server corresponding to the production console, so that after the first multimedia data stream is acquired by the acquisition device, it can be sent to the server and presented on the display device of the production console corresponding to the server. The display device of the production console can be divided into multiple display areas, and each display area is used to display the multimedia data stream acquired by the corresponding acquisition device. The first multimedia data stream that meets the preset conditions can be used as the second multimedia data stream. The second multimedia data stream is sent to the media data processing device so that the media data processing device performs special effects processing on the second multimedia data stream.

[0047] Exemplarily, taking the application scenario as a concert scenario as an example, correspondingly, the preset area is the area that accommodates the concert stage and the audience. Multiple acquisition devices can be deployed within the preset area. After each acquisition device acquires the first multimedia data stream, it can be transmitted to the display device of the production console corresponding to the production console, so as to display the corresponding first multimedia data stream in different display areas of the display device of the production console. The first multimedia data stream triggered by the user corresponding to the production console is used as the second multimedia data stream and sent to the media data processing device. After receiving the second multimedia data stream, the media data processing device can perform special effects processing on the second multimedia data stream to obtain the third multimedia data stream.

[0048] S120. Receive the third multimedia data stream fed back by the media data processing device and send the third multimedia data stream to the first display device for display.

[0049] Among them, the first display device is a device deployed within the preset area that can be viewed by multiple user objects for the picture content. Optionally, taking the application scenario as a concert scenario as an example, the first display device is deployed on the large electronic screen in the concert area. That is to say, the first display device is the display public screen placed within the preset area.

[0050] It can be understood that after the media data processing device processes and obtains the third multimedia data stream, the third multimedia data stream can be fed back to the server corresponding to the production console, so as to display the third multimedia data stream based on the display device of the production console corresponding to the server of the production console, and display the third multimedia data stream on the first display device placed within the preset area.

[0051] After receiving the first multimedia data streams sent by at least two acquisition devices, the technical solution provided by the embodiments of the present disclosure can send the second multimedia data stream that meets the preset conditions to the media data processing device, so that the media data processing device performs special effect processing on the second multimedia data stream to obtain the third multimedia data stream after special effect processing. After receiving the third multimedia data stream fed back by the media data processing device, the third multimedia data stream can be presented on the first display device. At this time, the content presented on the first display device is mainly the picture content after special effect processing and related to the users within the preset area. Therefore, the interactivity of users participating in the activity is improved.

[0052] Taking the application scenario of holding a concert as an example to illustrate the implementation link, multiple acquisition devices (cameras) can be deployed in the concert venue. All the acquisition devices communicate with the devices corresponding to the production control desk. A public display device (the first display device) can be deployed in the activity area. The first display device communicates with the devices of the production control desk and is used to present the second multimedia data stream or the third multimedia data stream on the first display device. It can be understood that after the camera captures the first multimedia data stream, it can be presented on the display device of the production control desk. At this time, the first multimedia data stream can include the video stream corresponding to the audience, the video stream corresponding to the stage, the video stream corresponding to the guests, and so on. If a certain video stream needs to be presented on the first display device after special effect processing, the first multimedia data stream that meets the preset conditions (that is, the first multimedia data stream that needs to be presented) can be sent to the media data processing device as the second multimedia data stream. After receiving the second multimedia data stream, the media data processing device can call the special effect processing model. For example, based on the special effect processing model, the faces of the users in the second multimedia data stream are processed into donkey face special effects to obtain the third multimedia data stream. After the third multimedia data stream is sent to the display device corresponding to the production control desk, it is sent to the first display device for presentation to achieve the effect of interacting with the audience or guests.

[0053] Through special effect interaction on the first display device, the users participating in the activity no longer passively watch the performance and can interact with the performers. There is a better sense of fun and interactive atmosphere at the scene. At this time, the special effects are no longer limited to short videos and online live broadcast scenarios, but can also play a greater role in offline performance scenarios. Moreover, after the users participating in the activity take pictures of the third multimedia data stream presented on the first display device, they can display it in various application programs, further improving the effect of activity promotion.

[0054] Based on the foregoing embodiments, multiple acquisition devices deployed in a preset area can acquire the first multimedia data stream of this area, and send the first multimedia data stream that meets the preset conditions to the media data processing device, so that the media data processing device performs special effect processing on this multimedia data stream. In this embodiment, the second multimedia data stream that meets the preset conditions is determined based on the following method:

[0055] Display the first multimedia data streams acquired by at least two acquisition devices in multiple display areas of the display interface, where the first multimedia data streams presented in each display area are different; in response to a trigger operation on the first multimedia data stream presented in any display area, use the triggered first multimedia data stream as the second multimedia data stream; or, determine the second multimedia data stream from multiple first multimedia data streams according to the special effect processing order and preset duration of at least two acquisition devices configured in advance. Determine the second multimedia data stream based on the analysis result of the first multimedia data stream presented in the display area

[0056] In this embodiment, the display interface corresponds to the interface presented by the display device of the production switcher. Since the server corresponding to the production switcher communicates with multiple acquisition devices, the first multimedia data streams acquired by the acquisition devices can be presented on the display interface corresponding to the production switcher. When there are multiple acquisition devices, in order to simultaneously display multiple first multimedia data streams on the display interface, the display interface can be divided into multiple display areas. Each display area is used to present the corresponding first multimedia data stream. That is, the first multimedia data streams presented in all display areas are acquired by different acquisition devices.

[0057] The user of the production switcher can click on the display area and use the first multimedia data stream corresponding to the clicked display area as the second multimedia data stream. Or, the display interface may include a selection identifier for each first multimedia data stream, and use the first multimedia data stream corresponding to the identifier triggered by the user as the second multimedia data stream. Correspondingly, the preset conditions correspond to the trigger operation on the display area or the identifier of the first multimedia data stream.

[0058] The advantage of determining the second multimedia data stream in this way is that: the user corresponding to the production switcher has a certain aesthetic ability. Determining the second multimedia data stream based on their selection can, on the one hand, achieve natural transition of the picture, and on the other hand, present the high-quality or interesting content acquired on the first display device to improve the user's participation during the event.

[0059] Of course, to improve the convenience of determining the second multimedia data stream, the second multimedia data stream can be determined based on an automated method. Optionally, the special effect processing order of each acquisition device and the special effect video duration corresponding to each acquisition device can be pre-configured. The special effect video duration can be understood as the duration of the second multimedia data stream, that is, the first multimedia data stream collected within a certain period of time is sequentially sent to the media data processing device as the second multimedia data stream. The special effect processing order can be understood as the order in which the first multimedia data stream collected by the acquisition device is used as the second multimedia data stream, which is pre-set. Exemplarily, there are three acquisition devices respectively labeled as Device 1, Device 2, and Device 3. The special effect processing order is Device 1, Device 3, and Device 2. The duration of the first multimedia data stream collected by each acquisition device that can be used as the second multimedia data stream is 1 minute. The first multimedia data stream collected by Device 1 can be used as the second multimedia data stream. When it is detected that the duration as the second multimedia data stream reaches the preset duration of 1 minute, the first multimedia data stream collected by Device 3 is used as the second multimedia data stream. When it is detected that the duration as the second multimedia data stream reaches the preset duration of 1 minute, the first multimedia data stream collected by Device 2 is used as the second multimedia data stream. The above operations are repeated until no multimedia data stream collected by the acquisition device is received or an instruction to stop determining the second multimedia data stream in this way is received. In this case, the preset condition corresponds to the special effect processing order and the preset duration of the pre-configured acquisition device.

[0060] The advantage of determining the second multimedia data stream in the above way is that it can improve the efficiency and convenience of determining the second multimedia data stream.

[0061] Of course, another way to determine the second multimedia data stream can be: based on the analysis result of the received first multimedia data stream, determine the second multimedia data stream.

[0062] It can be understood that after the server corresponding to the production control desk receives the first multimedia data stream, the first multimedia data stream can be evaluated for the richness of the picture content, and the first multimedia data stream with rich picture content is used as the second multimedia data stream. Correspondingly, the preset condition is the richness of the picture content of the first multimedia data stream. The richness of the picture content can be determined according to existing models.

[0063] The advantage of this method is that the second multimedia data stream can be automatically determined according to the richness of the picture content, which can not only ensure the automation of determining the second multimedia data stream, but also ensure the richness of the picture content presented on the first display device.

[0064] It can also be to use the multimedia data stream collected in the pre-set interaction session as the second multimedia data stream.

[0065] It should be noted that it can also be determined based on one or a combination of the above methods for the second multimedia data stream.

[0066] The method provided by the embodiments of the present disclosure can adopt the above method to determine the second multimedia data stream that meets the preset conditions, improving the convenience of determining the second multimedia data stream and the effect of picture transition coordination.

[0067] Based on the above technical solution, after the second multimedia data stream is determined, the second multimedia data stream can be directly presented on the first display device. It can also be that the second multimedia data stream is sent to the media data processing device, so that the media data processing device performs special effects processing on the second multimedia data stream to obtain a third multimedia data stream, and the third multimedia data stream is presented on the first display device.

[0068] Based on the above, before obtaining the third multimedia data stream, it is necessary to first send the second multimedia data stream to the media data processing device for processing, and then feedback it to the server corresponding to the production control desk. After that, it is presented on the first display device, and there are multiple transmission links. To solve the problem of latency caused during the transmission process, corresponding data acquisition cards can be deployed in the server corresponding to the production control desk and the media data processing device.

[0069] Optionally, the second multimedia data stream that meets the preset conditions is sent to the media data processing device based on the configured data acquisition card.

[0070] Among them, the data acquisition card SDI (Serial Digital Interface) is a data acquisition card for collecting video signals. This acquisition card has the functions of high-quality signal acquisition and multi-format support. At the same time, the SDI acquisition card has a hardware compression encoding function, which can perform real-time compression while collecting video, thereby reducing the burden on the computer CPU and facilitating video storage and transmission. Further, the encoding parameters are usually adjustable, such as resolution, bit rate, etc. Based on this, the second multimedia data stream can be encoded and sent to the media data processing device based on the SDI acquisition card, thereby improving the data transmission efficiency and reducing the latency duration.

[0071] The embodiments of the present disclosure can be applied in scenarios such as network video live broadcast, video production, and post-editing. Therefore, the first multimedia data stream collected by the camera can be converted into a format suitable for network transmission based on the data acquisition card, and then played through relevant software.

[0072] After sending the second multimedia data stream to the media data processing device based on the data acquisition card, the second multimedia data stream can be analyzed and processed based on the media data processing device, so as to obtain a third multimedia data stream. Figure 2 The following is a schematic flowchart of an information display method provided by an embodiment of the present disclosure, as Figure 2 shown, the method includes:

[0073] S210. Receive a second multimedia data stream based on the data acquisition card in the media data processing device.

[0074] It can be understood that: the second multimedia data stream sent by the server corresponding to the director console can be received by the media data processing device. When the media data processing device receives the second multimedia data stream, it indicates that the second multimedia data stream needs to be processed. At this time, the corresponding special effect processing model can be called for special effect processing.

[0075] S220. Invoke a special effect processing model corresponding to the second multimedia data stream, and perform special effect processing on the second multimedia data stream based on the special effect processing model to obtain a third multimedia data stream.

[0076] Among them, the special effect processing model is a model for performing special effect processing on the second multimedia data stream. The special effect processing model is determined based on the pre-provided special effect requirement description information. The activity organizer or the special effect requirement party may pre-provide the special effect requirement description information. Optionally, in the scenario of holding a concert, the organizer of the concert may provide the requirement description information. The special effect requirement description information can be conveyed in forms such as voice, text, image, video, etc. Optionally, if the activity organizer wants to undertake an activity on caring for giant pandas, the special effect requirement description information may be a text description of processing the user's face in the collected multimedia data stream into a panda special effect. Then, the first model can be a model for processing the user into a panda special effect; if the activity organizer holds a concert for a certain singer and the theme of the concert is "happy", the first model can be a special effect processing for making the facial features of the user in the multimedia data stream happy. The specific form of the effect processed by the first model can be adjusted according to the needs of the activity organizer, so as to both perform special effect processing on the media data stream and meet the special effect requirement description information provided by the activity organizer.

[0077] Further, the special effect effect obtained by processing the first model is at least related to the special effect element used to describe the special effect presentation effect in the special effect requirement description information. It can be understood that at least one special effect element is a content in the special effect requirement description text, and this content can determine the special effect processing result of the first model.

[0078] Specifically, after the media data processing device receives the second multimedia data stream, it can retrieve the first model adapted to the second multimedia data stream to perform special effect processing on the second multimedia data stream based on the first model, thereby obtaining the third multimedia data stream.

[0079] The advantage of processing the second multimedia data stream in the above manner is that the picture content presented in the second special effect video stream can be adjusted, thereby enriching the presented content in the second multimedia data stream. Correspondingly, when the third multimedia data stream obtained by the special effect is presented on the first display device, the users in the active display area can be provided with the interest of watching the picture content on the first display device when watching the picture content on the first display device.

[0080] After the media data processing device receives the second multimedia data drop, it can convert the image buffer buffer of the CPU into a GPU texture for special effect rendering, and render to obtain the third multimedia data stream.

[0081] In this embodiment, the special effect processing model can be a model for performing special effect processing on the user's facial features in the multimedia data stream, a model for stylizing the entire picture content, or a model for performing two-dimensional and three-dimensional animation processing on the user. The specific functions that the special effect processing model can implement are not limited here and can be developed and designed according to specific actual needs.

[0082] It should be noted that based on the data acquisition card, the data format of the second multimedia data stream can be converted into a preset format, and the second multimedia data stream in the preset format is sent to the media data processing device. Correspondingly, after the media data processing device receives the second multimedia data stream corresponding to the data acquisition card, it can first perform format conversion and resolution adjustment to make it meet the special effect processing requirements. Further, after processing to obtain the third multimedia data stream, the third multimedia data stream can be subjected to format conversion to send the third multimedia data stream to the server corresponding to the video switcher based on the data acquisition card in the media data processing device, and then push it to the first display device for presentation.

[0083] It should also be noted that a rendering area for the video can be created on the media data processing device. The advantage of creating the rendering area is that it can be adaptively adjusted according to the resolution of the first display device (large screen), ensuring that the video can be clearly displayed on large screens with different resolutions. When the media data processing device receives the second multimedia data stream, the multimedia data stream collected by the SDI is converted into the RGBA format. When the third multimedia data stream is presented after the special effect processing, seamless switching can be achieved, so as to ensure that the users participating in the activity can see the picture content after the special effect processing in real time.

[0084] Further, a device selection area can be presented on the display device of the production control console. In this device selection area, all detected SDI input and output devices, including the device names, can be displayed in the form of a UI. When debugging devices in the preset area, the SDI route to be used can be selected by clicking on the list options.

[0085] In the technical solution provided by the embodiments of the present disclosure, after the second multimedia data stream is determined, the second multimedia data stream can be sent to the media data processing device based on the data acquisition card. After receiving the second multimedia data stream, the media data processing device can determine the special effect processing model corresponding to the second multimedia data stream, and then perform special effect processing on the second multimedia data stream based on the special effect processing model to obtain the third multimedia data stream after special effect processing. Since the third multimedia data stream is a video stream after special effect processing and may include the special effect content of a certain user in the active area, the enthusiasm of users to participate in the activity can be improved.

[0086] On the basis of the foregoing embodiments, for all multimedia data streams, the corresponding special effect processing models can be the same. Of course, in order to further improve the effect of presenting diverse special effect content, that is, the picture diversity of the third multimedia data stream presented in the first display device, multiple special effect processing models can be created according to the special effect requirement description information, and then the third multimedia data stream that is most suitable for the second multimedia data stream can be determined.

[0087] In this embodiment, the special effect processing model corresponding to the second multimedia data stream can be determined based on the following method:

[0088] The first method is: using the pre-deployed special effect processing model as the special effect processing model.

[0089] It can be understood that a special effect processing model is created in advance, and regardless of what the received second multimedia data stream is, it can be processed based on this special effect processing model. That is to say, the pre-deployed special effect processing model is directly used as the model for special effect processing of the second multimedia data stream.

[0090] The second method is: retrieving the special effect processing model from multiple special effect processing models according to the device identifier of the acquisition device corresponding to the second multimedia data stream; wherein, each device identifier is associated with a special effect model.

[0091] Among them, for each acquisition device, the acquisition area range is different. For example, device A mainly acquires the multimedia data stream in area A, and device B mainly acquires the multimedia data stream in area B. There may be certain differences in the user types or scenarios corresponding to each area. Based on this, multiple special effect processing models can be pre-trained, and different acquisition areas (acquisition devices) correspond to one special effect processing model. The device identifier of the acquisition device can be associated with the corresponding special effect processing model. When the second multimedia data stream is received, the special effect processing model can be retrieved according to the device identifier of the acquisition device of the second multimedia data stream.

[0092] It can be understood that when the second multimedia data stream is sent to the media data processing device, the device identifier of the acquisition device corresponding to the second multimedia data stream can be sent to the media data processing device together. When the media data processing device receives the second multimedia data stream, it can retrieve the special effect processing model associated with it according to the device identifier in the second multimedia data stream, so as to process the second multimedia data stream into a special effect video stream based on the special effect processing model.

[0093] Exemplarily, there are three acquisition devices in the preset area, which are respectively marked as device 1, device 2, and device 3. A special effect processing model 1 corresponding to device 1, a special effect processing model 2 corresponding to device 2, and a special effect processing model 3 corresponding to device 3 are pre-created. If it is necessary to send the second multimedia data stream acquired by device 1 to the media data processing device, the device identifier of device 1 and the second multimedia data stream can be sent to the media data processing device together. After the media data processing device receives the second multimedia data stream, it can obtain the device identifier 1 and retrieve the special effect processing model 1 associated with the device identifier 1. The second multimedia data stream is processed with special effects based on the special effect processing model 1.

[0094] The third implementation method can be: retrieving the special effect processing model from multiple special effect processing models according to the model identifier carried in the second multimedia data stream; wherein, the model identifier is determined based on the special effect thumbnail triggered by the first user on the display interface, and the special effect thumbnail is the picture content obtained after multiple special effect processing models perform special effect processing on the preset video stream.

[0095] Among them, the first user corresponds to the production control desk. At the same time, multiple special effect thumbnails can be presented in a specific area of the display interface. The number of special effect thumbnails is related to the number of special effect processing models. The content of the special effect thumbnails is related to the special effect processing effects of the special effect processing models. Each special effect processing model can process a certain picture, and the corresponding rendering effect after processing can be displayed as a thumbnail on the display interface. The advantage of presenting multiple special effect thumbnails on the display interface is that it can facilitate the first user to timely understand the special effect processing results corresponding to each special effect model. Furthermore, when determining the second multimedia data stream, the first user can select the special effect model corresponding to the special effect thumbnail according to their appreciation ability, thereby improving the coordination effect of the picture content.

[0096] It can be understood that the preset media data can be input into the special effect processing models respectively. Each special effect processing model can process the preset media data to obtain a schematic diagram of the effect corresponding to the preset media data under each special effect processing model. To facilitate the first user corresponding to the production control desk to timely understand the special effect processing results corresponding to each special effect processing model, the thumbnail corresponding to the schematic diagram of the effect can be displayed on the display interface. This thumbnail is used as the special effect thumbnail. When obtaining the second multimedia data stream, if a specific special effect model is required to perform special effect processing on it, the special effect thumbnail corresponding to the special effect processing model can be selected on the display interface. After the selection of the special effect thumbnail is completed, the model identifier corresponding to the special effect thumbnail and the second multimedia data stream can be jointly sent to the media data processing device. After receiving the second multimedia data stream, the media data processing device can retrieve the special effect processing model corresponding to the model identifier according to the model identifier carried in the second multimedia data stream.

[0097] Based on the above, the special effect processing model can be determined based on the trigger selection of the first user.

[0098] Of course, the preset area usually includes invited users, and these special effect users can be used as preset objects. To reflect the differences of the invited users, real-time face analysis can be performed on the second multimedia data stream to determine whether the second multimedia data stream includes the facial features corresponding to the invited users. If the facial features corresponding to the invited users are included, the special effect processing model corresponding to the invited user can be retrieved to perform special effect processing on it. Of course, if the facial features of the invited users are not included, it can be processed based on the currently used special effect model.

[0099] Optionally, in the process of performing special effect processing on the second multimedia data stream based on the special effect processing model to obtain the third multimedia data stream, the method further includes: when it is detected that the second multimedia data stream includes a preset object, performing special effect processing on the preset object based on the preset model corresponding to the preset object.

[0100] It can be understood that during the special effect processing of the second multimedia data stream based on the determined special effect model, if it is detected that the second multimedia data stream includes a preset object, the preset model corresponding to the preset object can be retrieved for special effect processing of the preset object. Of course, when the second multimedia data stream does not include a preset object, the determined special effect processing model is continued to be used to process the second multimedia data stream.

[0101] Exemplarily, in the scenario of a concert, there is a special guest A. When sending the second multimedia data stream corresponding to the special guest A to the media data processing device, the user's facial features in the second media data stream can be recognized and analyzed. When it is determined that there are facial features corresponding to the special guest A, the preset model corresponding to the special guest A is retrieved for processing it to obtain a third multimedia data stream.

[0102] In this embodiment, when there are multiple preset objects and the special effect processing models corresponding to each preset object are different, the special effect processing models corresponding to each preset object can be retrieved and processed respectively to display the schematic diagrams of the effects after different special effect processing models process different preset objects in the same picture.

[0103] Exemplarily, if the second multimedia data stream includes multiple special guests at the same time, the special effect processing models corresponding to each special guest can be retrieved respectively and applied to the corresponding special guests to obtain the schematic diagrams of the effects of different special guests under different special effect processing models in the same picture.

[0104] It should also be noted that in practical applications, if a specific special effect processing model is required for special effect processing of the second multimedia data stream, the special effect processing model can be determined based on the trigger operation of the first user, or the specific special effect processing model can be determined based on the communication between the first user and the media data processing user.

[0105] In this embodiment, the special effect processing of the second multimedia data stream to obtain the third multimedia data stream can be: based on the special effect processing model, identifying the preset parts of the user in the second multimedia data stream and adding special effects to the preset parts to obtain the third multimedia data stream corresponding to the second multimedia data stream.

[0106] Among them, the preset parts can be any part of the limb trunk or at least one part of the facial features.

[0107] It can be understood that: based on the special effect processing model, users in the second media data stream can be identified, and the preset parts of the users can be identified. After the preset parts are identified, target special effects can be added to the preset parts. The second multimedia data stream with the target special effects added is used as the third multimedia data stream.

[0108] That is to say, based on the special effect processing model, special effect elements can be added to the users in the second multimedia data stream. Through rendering processes such as image algorithms, face detection algorithms, and special effect generation, the natural integration of special effects and video content is achieved. At the same time, when the special effect processing model is a face processing model, it can be controlled that the special effects move in real time following the movement of the face, thereby ensuring that the effects of the special effects in the low-light scene of the concert can still accurately follow the users.

[0109] Exemplarily, in the concert scene, the preset part is the facial features on the face, and the target special effect is the special effect of processing the face into a donkey face. Identify the users in the second multimedia data stream, and identify the facial parts of the users. Process the facial parts into donkey face special effects, and use the obtained multimedia data stream as the third multimedia data stream.

[0110] It should be noted that taking the application scenario of the event being a concert scene as an example, the special effect processing model can be determined according to the special effect requirement description information provided by the concert team (event organizer) (this description information includes the concert theme, style, and specific requirements of the interactive session). The number of special effect processing models can be one or more, and the corresponding special effect processing effects can be static special effects or dynamic special effects, and the specific special effect content can be set according to actual needs. For example, it can be stylized special effects, 2D special effects, 3D animation special effects, etc. At the same time, the special effect processing model can be optimized to ensure smooth operation under different hardware configurations and at the same time ensure the fusion effect of the special effects and the multimedia data stream.

[0111] After obtaining the third multimedia data stream through special effect processing of the second multimedia data stream, the technical solution provided by the embodiments of the present disclosure can present the third multimedia data stream on the first display device in the preset area, that is, the public display device, and this public display device can be viewed by the users in the preset area. Since the displayed third multimedia data stream is related to the users in the preset area, not only the richness and interest of the picture content are improved, but also the effect of improving the enthusiasm of the users to participate in the event is achieved.
