[0067] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0068] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0069] Figure 1 is a schematic diagram of an implementation environment provided by an embodiment of the present application. Figure 1 , the implementation environment includes a terminal 101 and a server 102. The terminal 101 and the server 102 are connected via a wireless or wired network. Exemplarily, the terminal 101 is a computer, a mobile phone, a tablet computer or other terminals. Exemplarily, the server 102 is a background server of an application or a cloud server that provides cloud computing and cloud storage services.

[0070] Exemplarily, a video application is installed in the terminal 101, and the video application is a video application in the operating system of the terminal 101, or a video application provided by a third party. The terminal 101 can implement functions such as data transmission and message interaction through the video application, thereby realizing the video playback function.

[0071] In the embodiment of the present application, the server 102 is used to send a video playback instruction to the terminal 101. The terminal 101 is used to receive the video playback instruction, and in response to the video playback instruction, obtain playback strategy information, the playback strategy information indicating a strategy for selecting a playback unit and a playback mode from at least one playback unit in the current terminal and at least one playback mode preset for each playback unit, wherein each playback mode includes a combination of a decoding mode and a rendering mode. Then, based on the playback strategy information, the terminal 101 determines the target playback unit and the target playback mode of the target video to be played; and plays the target video according to the target playback mode through the target playback unit.

[0072] The video playback method provided in this application can be applied to any video playback scenario. For example, in the scenario of playing multiple surveillance video images. Or, in the case of a multi-party video call, playing multi-party video images. Or, when watching a movie, playing multiple different movie images, etc., this application does not limit this.

[0073] Figure 2 This is a flow chart of the first embodiment of the video playback method of the present application. Figure 2 Taking the execution subject as a terminal as an example, the video playback method provided by the embodiment of the present application includes:

[0074] Step S10: In response to the received video playback instruction, playback strategy information is obtained, where the playback strategy information indicates a strategy for selecting a playback unit and a playback mode from at least one playback unit in the current terminal and at least one playback mode preset for each playback unit, wherein each playback mode includes a combination of a decoding mode and a rendering mode.

[0075] The video play instruction is a command issued by a user or a server, requesting the terminal to play a specified video content. For example, the terminal generates a video play instruction based on a click on a user interface, a voice command, or other forms of input. Alternatively, the terminal receives a video play instruction issued by a server. Optionally, the video play instruction carries a target video to be played. Optionally, the video play instruction also carries other information related to the target video to be played, such as the video stream type of the target video, the size of the video, etc.

[0076] At least one playback unit is currently configured in the terminal, and each playback unit is preset with at least one playback mode. The playback strategy information defines the configuration method of the playback unit and the playback mode in the terminal, as well as information on how to select the playback unit and the playback mode. For example, the playback strategy information includes a variety of selection logics and conditions for determining which playback unit and which playback mode to use in a specific situation. Optionally, the playback strategy information is stored in the terminal or in the video application of the terminal. Accordingly, the terminal can obtain the playback strategy information locally or from the video application.

[0077] The playback unit is a module or component in the terminal that is responsible for video playback. Exemplarily, the playback unit includes a CPU (Central Processing Unit), a graphics card, a GPU (Graphics Processing Unit), etc., which is not limited in the embodiments of the present application. The playback mode is a specific configuration adopted by the playback unit when performing a video playback task. Each playback mode includes a combination of a decoding mode and a rendering mode to adapt to different playback environments and requirements.

[0078] Decoding is the process of restoring compressed video data to the original image frame. The decoding mode refers to the way of video decoding. The decoding modes include hardware decoding and software decoding. Among them, hardware decoding uses the dedicated hardware of the device, such as GPU, for decoding. This decoding method has higher decoding speed and lower power consumption. Software decoding uses the CPU for decoding and is suitable for devices without dedicated hardware decoders.

[0079] Rendering is the process of outputting decoded image frames to the screen. Rendering mode refers to the way image frames are displayed on the screen. Rendering modes include hardware rendering and software rendering. Hardware rendering refers to the use of dedicated hardware of the device, such as GPU, to render images. Software rendering refers to the use of the device's CPU to render images. Software rendering does not rely on dedicated hardware and is completely implemented by software algorithms.

[0080] The combination of the playback mode including the decoding mode and the rendering mode means that the decoding mode and the rendering mode are combined to realize multiple playback modes. Optionally, the combination of the decoding mode and the rendering mode in the present application includes at least two of the following: hardware decoding and hardware rendering; hardware decoding and software rendering; software decoding and hardware rendering; software decoding and software rendering. By combining the decoding mode and the rendering mode to realize these multiple different playback modes, different device performance and playback requirements can be met.

[0081] Optionally, the playback strategy information includes at least one playback unit corresponding to various terminal models and at least one playback mode corresponding to each playback unit. Accordingly, the terminal determines the target playback unit and the target playback mode of the target video to be played based on the playback strategy information, including: the terminal queries at least one playback unit corresponding to the current terminal model and at least one playback mode corresponding to each playback unit from the playback strategy information based on the current terminal model; and determines the target playback unit and the target playback mode of the target video to be played from at least one playback unit corresponding to the current terminal model and at least one playback mode corresponding to each playback unit. This solution can ensure that the selected playback mode matches the hardware and software environment of the terminal by selecting the appropriate playback unit and playback mode based on the current terminal model, thereby improving the compatibility and stability of video playback. It can also maximize the use of the terminal's hardware resources and improve the performance of video playback.

[0082] Step S20: Determine the target playback unit and the target playback mode of the target video to be played based on the playback strategy information.

[0083] Exemplarily, the terminal determines the target playback unit and the target playback mode of the target video to be played based on the playback strategy information, including: the terminal randomly selects the target playback unit from at least one playback unit based on the playback strategy information, and randomly selects the target playback mode from at least one playback mode of the target playback unit. This method can simply and efficiently realize the adaptive allocation of playback units and playback modes.

[0084] Exemplarily, the playback strategy information includes at least one playback unit that matches different video bitstream types, and at least one playback mode that matches different video bitstream types. Accordingly, based on the bitstream type of the target video to be played, the terminal selects a playback unit that matches the bitstream type of the target video from at least one playback unit in the current terminal as the target playback unit, and selects a playback mode that matches the bitstream type of the target video from at least one playback mode of the target playback unit as the target playback mode. This approach can ensure the compatibility of the determined target playback unit and target playback mode with the target video to be played, thereby improving the video playback effect.

[0085] Optionally, the playback strategy information includes at least one of the following restrictive conditions: a playback quantity threshold of a playback unit, a playback quantity threshold of a playback mode, a playback unit priority, a playback mode priority, and a playback unit resource utilization threshold. Among them, the playback quantity threshold of a playback unit is the maximum number of videos that a playback unit can play. The playback quantity threshold of a playback mode refers to the maximum number of videos that can be played in this playback mode. The playback unit priority determines which playback unit will be applied first when there are multiple playback units. The playback mode priority determines which playback mode will be applied first when there are multiple playback modes. The playback unit resource utilization threshold refers to the maximum resource utilization preset by the playback unit.

[0086] Correspondingly, the terminal determines the target playback unit and target playback mode of the target video to be played based on the playback strategy information, including: selecting a target playback unit that meets the restriction conditions in the playback strategy information from at least one playback unit, and selecting a target playback mode that meets the restriction conditions in the playback strategy information from at least one playback mode of the target playback unit.

[0087] Exemplarily, the playback strategy information includes the priority of the playback unit and the priority of the playback mode. Accordingly, the terminal selects the playback unit with the highest priority from at least one playback unit as the target playback unit. The playback mode with the highest priority from at least one playback mode of the target playback unit is selected as the target playback mode.

[0088] Exemplarily, the playback strategy information includes a playback quantity threshold of a playback unit and a playback quantity threshold of a playback mode. Accordingly, the terminal selects a playback unit whose current video playback quantity is less than the corresponding playback quantity threshold from at least one playback unit as a target playback unit. A playback mode whose current video playback quantity is less than the corresponding playback quantity threshold is selected from at least one playback mode of the target playback unit as a target playback mode.

[0089] Exemplarily, the playback strategy information includes a playback quantity threshold, a resource utilization rate threshold, and a playback mode priority of the playback unit. Accordingly, the terminal selects a playback unit whose current video playback quantity is less than the corresponding playback quantity threshold and whose target resource utilization rate is less than the resource utilization rate threshold from at least one playback unit as a target playback unit. The playback mode with the highest priority is selected from at least one playback mode of the target playback unit as the target playback mode.

[0090] The playback strategy information in the embodiment of the present application includes at least one restriction condition, which is used to screen target playback units and target playback modes that meet the condition. By selecting a target playback unit that meets the restriction condition in the playback strategy information from at least one playback unit, and selecting a target playback mode that meets the restriction condition in the playback strategy information from at least one playback mode of the target playback unit, on the one hand, it is possible to quickly screen out playback units and playback modes that meet the condition, thereby reducing unnecessary search time; on the other hand, by setting flexible conditions, the video playback method can adapt to various terminal hardware and software environments, greatly enhancing the adaptability of the video playback method on various domestic terminals.

[0091] Step S30: Play the target video according to the target playback mode through the target playback unit.

[0092] Optionally, this step is implemented as follows: the terminal decodes the target video according to a decoding mode in a target playback mode through a target playback unit, renders the target video according to a rendering mode in the target playback mode, and then plays the target video on a display.

[0093] The video playback solution provided by the present application provides multiple playback modes for various combinations of playback units on the terminal through the combination of the decoding mode and the rendering mode of the playback unit. In response to the received video playback instruction, the playback strategy information is obtained. Since the playback strategy information indicates the strategy of selecting the playback unit and the playback mode from at least one playback unit in the current terminal and at least one playback mode preset by each playback unit, the target playback unit and the target playback mode of the target video to be played are determined based on the playback strategy information, thereby realizing the adaptive allocation of the playback unit and the playback mode. The target video is played by the adaptively allocated target playback unit and the target playback mode, which improves the rationality of resource utilization, thereby making full use of the capabilities of domestic terminal hardware.

[0094] In some embodiments, the playback strategy information includes the priority order of at least one playback unit and the priority order of at least one playback mode of each playback unit. Accordingly, the terminal determines the target playback unit and the target playback mode of the target video to be played based on the playback strategy information, including: the terminal determines the playback unit that currently meets the alternative condition based on the priority order of at least one playback unit, and determines the playback unit that first meets the alternative condition as the target playback unit; based on the priority order of at least one playback mode of the target playback unit, determines the playback mode that currently meets the alternative condition, and determines the playback mode that first meets the alternative condition as the target playback mode.

[0095] Optionally, the video playback parameters of a playback unit with a higher priority are superior to those of a playback unit with a lower priority. The video playback parameters are used to measure the video playback quality and / or resource usage of the playback unit. The better the video playback parameters, the better the video playback quality of the playback unit and / or the lower the resource usage. Exemplarily, the video playback parameters indicate at least one of the decoding speed, rendering speed, rendering effect, playback smoothness, playback jamming and resource usage of the playback unit. Optionally, the video playback parameters of a playback mode with a higher priority are superior to those of a playback mode with a lower priority. The video playback parameters are used to measure the video playback quality and resource usage corresponding to the playback mode. The better the video playback parameters, the better the video playback quality and / or the lower the resource usage corresponding to the playback mode.

[0096] The alternative condition is a standard or condition that determines whether a certain playback unit or playback mode can be selected. The present application determines whether each playback unit meets the alternative condition in order of priority. Once a playback unit that meets the alternative condition is determined, the playback unit is determined as the target playback unit, and playback units with lower priorities are no longer judged. After the target playback unit is determined, for at least one playback mode of the target playback unit, each playback mode is determined in order of priority to determine whether it meets the alternative condition. Once a playback mode that meets the alternative condition is determined, the playback mode is determined as the target playback mode, and playback modes with lower priorities are no longer judged.

[0097] In the embodiment of the present application, the priority order of the playback unit and the playback mode is set, and the target playback unit and the target playback mode that meet the alternative conditions are determined according to the priority order. The playback unit and the playback mode assigned to the video to be played can be automatically adjusted based on the priority and the alternative conditions, so that these resources can be maximized under limited terminal resources to improve the playback efficiency. In addition, since the video playback parameters of the playback unit and the playback mode with a higher priority are better, the playback unit and the playback mode with a higher priority are preferentially selected according to the priority order, which ensures the video playback effect when the target video is played based on the selected target playback unit and the target playback mode.

[0098] Optionally, the alternative condition includes that the current number of video plays does not reach the playback number threshold. The playback number threshold is also included in the playback strategy information. Accordingly, the terminal determines the playback unit whose current number of video plays does not reach the playback number threshold as the target playback unit based on the priority order of at least one playback unit. The terminal determines the playback mode whose current number of video plays does not reach the playback number threshold as the target playback mode based on the priority order of at least one playback mode of the target playback unit. This scheme can balance resource allocation, that is, when the number of video plays of a playback unit with a higher priority reaches the threshold, the terminal will automatically select other playback units with a lower priority, and when the number of video plays of a playback mode with a higher priority reaches the threshold, the terminal will automatically select other playback modes with a lower priority. This can avoid a certain playback unit or playback mode being assigned too many tasks, thereby reducing the occurrence of video playback failures.

[0099] Optionally, the alternative condition includes that the target resource utilization rate does not reach the resource utilization rate threshold. The resource utilization rate threshold is also included in the playback strategy information. The target resource utilization rate represents the resource utilization rate when the target video is assigned. Accordingly, the terminal determines the playback unit whose target resource utilization rate does not reach the resource utilization rate threshold as the target playback unit based on the priority order of at least one playback unit. The terminal selects the playback mode with the highest priority from at least one playback mode of the target playback unit as the target playback mode based on the priority order of at least one playback mode of the target playback unit. This scheme can balance resource allocation, that is, when the target resource utilization rate of the playback unit with a higher priority reaches the threshold, the terminal will automatically select other playback units with a lower priority, so as to avoid a certain playback unit being assigned too many tasks, thereby reducing the occurrence of video playback failures. This mechanism helps to allocate playback resources more reasonably and improve the utilization rate of the terminal's hardware resources.

[0100] Optionally, the alternative conditions include that the current number of video plays does not reach the play number threshold, and the target resource utilization rate does not reach the resource utilization rate threshold. Accordingly, the terminal determines the play unit whose current number of video plays does not reach the play number threshold and the target resource utilization rate does not reach the resource utilization rate threshold as the target play unit based on the priority order of at least one play unit. Then, based on the priority order of at least one play mode of the target play unit, the terminal determines the play mode whose current number of video plays does not reach the play number threshold as the target play mode. This scheme determines the target play unit and the target play mode based on the priority of the play unit and the play mode, in combination with the play number threshold and the resource utilization rate threshold, which can further prevent a certain play unit or play mode from being overloaded, and helps to maintain the stability and reliability of the terminal video playback.

[0101] Optionally, the alternative condition includes that the current video playback quality meets the video quality condition. The video quality condition is also included in the playback strategy information. For example, the video quality condition includes at least one of the standards for video decoding speed, rendering speed, playback smoothness, and picture clarity. Accordingly, the terminal determines the playback unit whose current video playback quality meets the video quality condition first as the target playback unit based on the priority order of at least one playback unit. The terminal determines the playback mode whose current video playback quality meets the video quality condition first as the target playback mode based on the priority order of at least one playback mode of the target playback unit. The present application gives priority to playback units and playback modes with high priority and whose video playback quality meets the quality condition. When the current video playback quality of the playback unit or playback mode with high priority does not meet the quality condition, the playback unit and playback mode can be automatically selected and adjusted to ensure that the user can always watch high-quality video content, which helps to improve the user's viewing experience.

[0102] In some embodiments, the playback strategy information includes a playback quantity threshold for different video bitstream types for each playback mode of at least one playback unit. The bitstream of the target video belongs to the target bitstream type. Accordingly, the terminal determines the target playback unit and the target playback mode of the target video to be played based on the playback strategy information, including: the terminal determines the number of videos of the target bitstream type currently played by each playback mode of at least one playback unit; determines the playback mode in which the number of videos of the target bitstream type currently played is less than the corresponding playback quantity threshold as the target playback mode; and determines the playback unit corresponding to the target playback mode as the target playback unit.

[0103] Exemplarily, the video bitstream information is carried in the video playback instruction. Among them, the bitstream information includes information such as video resolution, video bitrate, video frame rate, and video encoding format. The video bitstream information determines the type of the video bitstream. Different types of bitstreams require different playback environments and playback resources. Therefore, different playback units or playback modes have different playback capabilities for videos of different bitstream types. Therefore, the present application sets a playback quantity threshold for different video bitstream types for each playback mode of at least one playback unit in the playback strategy information, and uses a corresponding playback quantity threshold for videos of different bitstream types to limit the video playback volume of each playback mode. In this way, the load size of each playback mode can be controlled and adjusted more accurately, which helps to allocate playback resources more reasonably and improve the utilization rate of the terminal's hardware resources.

[0104] Exemplarily, there are multiple playback modes in which the number of videos of the target code stream type currently being played is less than the corresponding playback number threshold. In this case, a playback mode with the highest priority is selected from the multiple playback modes as the target playback mode. Alternatively, a playback mode is randomly selected from the multiple playback modes as the target playback mode. Alternatively, the target resource utilization rates of the playback units corresponding to the multiple playback modes are determined respectively, and the playback mode corresponding to the playback unit with the target resource utilization rate less than the resource utilization rate threshold is determined as the target playback mode. Alternatively, the priorities of the playback units corresponding to the multiple playback modes are determined respectively, and the playback mode corresponding to the playback unit with the highest priority is determined as the target playback mode.

[0105] Optionally, the playback strategy information further includes the priority order of at least one playback unit and the priority order of at least one playback mode of each playback unit; in at least one playback mode of the last priority playback unit, the playback quantity threshold for each video bitstream type in the last priority playback mode is infinite. In this way, when the number of videos of the target bitstream type of the first priority playback mode in the first priority playback unit reaches the playback quantity threshold, all the videos of the target bitstream type to be played that are added subsequently can be played through the last priority playback mode in the last priority playback unit.

[0106] Figure 3 This is a schematic diagram of the corresponding relationship between the playback mode and the playback quantity threshold in the terminal. Figure 3 , where terminal A is the terminal model, video stream type A is the video stream type of the video to be played, and playback unit A and playback unit B are playback units in terminal A. Playback unit A sets a playback mode, namely, playback mode A. The maximum number of videos belonging to video stream type A that can be played by playback unit A under playback mode A is playback number threshold A. Playback unit B sets two playback modes, namely, playback mode B and playback mode C. The maximum number of videos belonging to video stream type A that can be played by playback unit B under playback mode B is playback number threshold B, and the maximum number of videos belonging to video stream type A that can be played under playback mode C is playback number threshold C. In addition, in this corresponding relationship, playback unit A is located above playback unit B, indicating that playback unit A has a higher priority in playing videos than playback unit B. Playback mode B is located above playback mode C, indicating that playback mode B has a higher priority in playing videos than playback mode C.

[0107] Optionally, a method for determining a playback quantity threshold for different video code stream types for each playback mode of at least one playback unit includes: the terminal determines the maximum number of video playbacks that can be achieved when any playback unit plays a video of any video code stream type in any playback mode under the condition that a playback condition is met; and the maximum number of video playbacks is determined as the playback quantity threshold for the playback mode of the playback unit for the video code stream type. The playback condition includes that the resource utilization rate of the playback unit does not exceed the resource utilization rate threshold, and the video playback quality meets the video quality condition. For example, the video quality condition includes at least one of a standard for video decoding speed, a standard for rendering speed, a standard for playback smoothness, and a standard for picture clarity.

[0108] The video playback quality of the playback unit in the playback condition meets the video quality condition, which can ensure the playback quality of each video in the playback unit, and the resource utilization rate of the playback unit in the playback condition does not exceed the resource utilization rate threshold, which can not only avoid the playback unit from being overloaded and ensure the playback quality of each video in the playback unit, but also avoid the playback unit from occupying too many hardware resources and affecting the video playback quality of other playback units. Therefore, the terminal determines the maximum number of video playbacks that can be achieved when any playback unit plays a video of any video stream type in any playback mode under the condition that the playback conditions are met, and determines the maximum number of video playbacks as the playback number threshold of the playback mode of the playback unit for the video stream type, and realizes adaptive allocation of multiple playback modes based on the playback number threshold, which can balance resource allocation and maximize the use of terminal hardware resources.

[0109] In some embodiments, the playback strategy information also includes a resource usage threshold of at least one playback unit. Accordingly, the terminal determines the target playback unit and the target playback mode of the target video to be played based on the playback strategy information, including: the terminal determines the target resource usage of at least one playback unit, the target resource usage represents the resource usage when the target video is assigned; the playback unit whose target resource usage is not greater than the resource usage threshold is determined as the target playback unit; the target playback mode is selected from at least one playback mode of the target playback unit. This solution can accurately control the resource usage of the playback unit and avoid excessive consumption of resources, so that the playback unit can ensure the video playback quality while not affecting the video playback quality of other playback units, thereby ensuring the multi-video playback effect of the terminal as a whole.

[0110] Resource utilization refers to the utilization rate of the hardware resources in the terminal by the playback unit. For example, the utilization rate of the CPU, graphics card, memory, and network resources. The resource utilization threshold refers to the maximum resource utilization rate set for the playback unit. Different resource utilization thresholds can be set for different resources. In addition, the setting of the resource utilization threshold is combined with the video playback effect of the playback unit. For example, the resource utilization threshold set by each playback unit can ensure that when the resource utilization rate of the playback unit is not greater than the resource utilization threshold, the video playback quality of the playback unit can meet the video quality conditions and will not affect the video playback quality of other playback units.

[0111] The target resource utilization rate refers to the resource utilization rate of the target playback unit when the target video to be played is assigned to the target playback unit. Since the video to be played has not yet been assigned to the target playback unit for processing, the target resource utilization rate is actually an estimated resource utilization rate.

[0112] Optionally, the terminal determines the target resource usage rate of at least one playback unit, including: the terminal obtains a first resource usage rate and a second resource usage rate of each playback unit, and determines the sum of the first resource usage rate and the second resource usage rate as the target resource usage rate, wherein the first resource usage rate is the current resource usage rate of the playback unit, and the second resource usage rate is the resource usage rate required for the playback unit to play the target video.

[0113] Exemplarily, the resource usage rate required for playing the target video, i.e., the second resource usage rate, is determined based on the video bitstream type of the target video. For example, the resource usage rate required for the playback unit to play any video of the target bitstream type is determined as the resource usage rate required for the playback unit to play the target video, wherein the bitstream of the target video belongs to the target bitstream type. The resource usage rate required for the playback unit to play the video of the target bitstream type can be stored in the terminal for easy retrieval.

[0114] In the embodiment of the present application, since the first resource usage rate is the current resource usage rate of the playback unit, and the second resource usage rate is the resource usage rate required by the playback unit to play the target video to be played, the sum of the first resource usage rate and the second resource usage rate can accurately represent the resource usage rate of the playback unit when the video to be played is assigned to the playback unit, thereby ensuring the video playback effect of the target playback unit determined based on the resource usage rate.

[0115] It should be noted that, in other embodiments, the first resource usage rate and the second resource usage rate may be weighted and summed to obtain the target resource usage rate. The weights of the first resource usage rate and the second resource usage rate may be set as required.

[0116] Optionally, the terminal obtains the second resource usage rate of the playback unit, including: the terminal obtains the resource usage rate threshold and the playback quantity threshold of the playback unit; and determines the ratio of the resource usage rate threshold to the playback quantity threshold as the second resource usage rate. Since the resource usage rate threshold is the maximum resource usage rate set for the playback unit, and the playback quantity threshold is the maximum number of videos that the playback unit can play, the ratio of the resource usage rate threshold to the playback quantity threshold can accurately represent the resource usage rate allocated to each video, and determining the resource usage rate as the second resource usage rate to represent the resource usage rate required for the playback unit to play the target video has high accuracy, which can ensure the video playback effect of the target playback unit subsequently determined based on the second resource usage rate.

[0117] Optionally, the resources required by the playback unit to play the video are of various types. For example, CPU resources, graphics card resources, memory resources, network resources, etc. Considering that the resources used by the playback unit to play the video are of various types, and the resource usage rate of each type of resource can affect the video playback effect of the playback unit, the terminal obtains the target resource usage rate of the playback unit for each type of resource, and determines the playback unit whose target resource usage rate of each resource is not greater than the corresponding resource usage rate threshold as the target playback unit, so as to better ensure the video playback effect of the target playback unit.

[0118] One point that needs to be explained is that, based on the resource utilization rate threshold, the terminal can also determine the target playback unit in combination with the video playback quantity threshold, or the terminal can also determine the target playback unit in combination with the playback unit priority. Further, the terminal combines the playback unit priority, playback quantity threshold, and resource utilization rate threshold to determine the target playback unit. In addition, when selecting a target playback mode from at least one playback mode of the target playback unit, the target playback mode can be determined in combination with the playback quantity threshold of the playback mode, the priority of the playback mode, etc. Please refer to the above embodiments for the specific combination method, which will not be repeated here.

[0119] Figure 4 A schematic diagram of a video allocation process. Figure 4After receiving the video playback instruction, the terminal reads the video stream type therein, and then judges in order according to the priority order of the playback unit to determine the target playback unit. First, determine the number of video plays of the current playback unit, and then determine the relationship between the number of video plays of the current playback unit and the playback number threshold. When the number of video plays reaches the playback number threshold, that is, the number of video plays is greater than or equal to the playback number threshold, determine the next playback unit. When the number of video plays is less than the playback number threshold, determine the relationship between the target resource utilization rate of the current playback unit and the resource utilization rate threshold. When the target resource utilization rate is greater than the resource utilization rate threshold, determine the next playback unit. When the target resource utilization rate is not greater than the resource utilization rate threshold, play the video through the current playback unit.

[0120] One thing that needs to be explained is that there are many types of terminal models launched by various manufacturers on the market, and the terminal software and hardware combinations are diverse. Video playback needs to be adapted and connected according to different software and hardware interfaces. In the existing technical solutions, video playback often uses separate full-hardware decoding, full-software decoding and other decoding methods in multiple windows. The decoding method is single, and there is a situation where the use of one resource reaches the upper limit, while other resources are wasted, and the terminal hardware capabilities cannot be maximized. On the other hand, due to the immaturity of the hardware ecosystem, there are inaccurate statistics on resource utilization, resulting in too many playback tasks being allocated to decoding resources, resulting in video playback freezes or black screens, poor video playback effects, and failure to meet user needs.

[0121] The video playback method proposed in this application can effectively improve the resource utilization of video playback on the terminal and improve the video playback effect when performing multi-window video playback, thereby meeting customer needs. First of all, the video playback method in this application can adapt to various combinations of playback units in the terminal, and realize adaptive allocation of multiple playback modes according to the decoding mode and rendering mode combination of the playback unit. Decoding, rendering mode scheduling, priority judgment and dynamic resource adjustment are performed for each video window to achieve the optimal decoding and rendering mode for each video window of a specific model, which can greatly enhance the adaptability of video applications on various terminals. In addition, combining the playback quantity threshold and the dynamic resource utilization rate, the playback unit and playback mode of the newly added video window are comprehensively determined, which can effectively avoid playback problems such as decoding jamming and image screen distortion caused by resource allocation transition. Under the condition of equal terminal hardware resources, the decoding effect of the video playback method in this application is smoother, and it does not affect other applications on the terminal, fundamentally reducing the terminal configuration cost.

[0122] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the video playback method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
