[0002] The management and allocation of cache resources are widely used in fields such as computer programming and network communications.

However, for different video application scenarios, the transmission and caching of video streams are subject to significant uncertainty.

[0003] In the prior art, in order to cover more video application scenarios, more buffer resources are usually allocated. However, in actual applications, due to the switching of video application scenarios, especially for high-resolution videos, the allocation of more buffer resources will occupy too much memory, resulting in resource waste.

[0026] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0027] The terms "first," "second," and "third" (if any) in the specification and claims of this application and the accompanying drawings are used to distinguish different objects, not to describe a specific order. In addition, the terms "comprises" and "comprising" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to the process, method, product, or apparatus.

[0028] In the process of filing this application, the applicant also found that: Figure 1 This is a flow chart of video decoding provided by the prior art. Figure 1 After obtaining the video stream, the computer device allocates cache resources (buffer) to the hardware / software decoder, then sends the video stream to the hardware / software decoder to start decoding, and finally outputs the decoded data to a file or transmits it to the screen for display.

[0029] The video encoding process is similar. Specifically, after obtaining raw video data (e.g., color-encoded YUV data), the computer allocates cache resources to the hardware / software decoder, then sends the raw video data to the hardware / software encoder for encoding. Finally, the encoded data is output to a file or sent to another device.

[0030] In the mobile Internet era, a large number of video playback and video interaction activities are involved, and complex video application scenarios, video stream transmission and caching are subject to great uncertainty. In the existing technology, in order to cover as many application scenarios as possible, more cache resources tend to be allocated when allocating cache resources. However, in actual applications, due to changes in scenarios, especially for high-resolution videos, too many cache resources will occupy a lot of memory due to allocation, resulting in resource waste. For example, when playing a 4K movie, a computer device can allocate 10 cache resources, and the cache space of each cache resource is approximately 12M. However, in actual use, the computer device detects that 4 cache resources are used, which can meet the application scenario, so the other 6 cache resources can be released, thereby saving 72M of memory space.

[0031] Please refer to Table 1 below, which shows the correspondence between some video resolutions and the cache resources used by frame videos.

[0032] Table 1

[0033]

[0034] Table 1 shows that as video resolution increases from the standard image format (352×288) to 8K, the pixels increase from 352×288 to 7680×4320, and the cache resources occupied by each video frame increase from 152KB to 50MB. This shows that for higher-resolution videos, the memory waste caused by redundant cache resources is more severe, and accordingly, the benefits of cache resource adjustment are greater.

[0035] Based on this, this application proposes a cache resource adjustment method and related products. By dynamically adjusting cache resources, memory space can be saved, thereby improving the smoothness of system operation. The following first introduces several application scenarios applicable to this application.

[0036] First, the encoding scenario. The cache resource adjustment scheme involved in this application can be applied to encoding scenarios, which may include but are not limited to scenarios such as image encoding, voice encoding, or video encoding. Accordingly, the cache data involved in this application in this scenario includes but is not limited to image data, voice data, video data, or other data that supports encoding.

[0037] Second, decoding scenarios. The cache resource adjustment scheme involved in this application can be applied to decoding scenarios, which may include but are not limited to scenarios such as image decoding, voice decoding, or video decoding. Accordingly, in this scenario, the cache data involved in this application includes but is not limited to image data, voice data, video data, or other data that supports decoding.

[0038] Third, other application scenarios. The cache resource adjustment scheme involved in this application can be applied to scenarios other than encoding and decoding scenarios, that is, non-encoding and decoding scenarios. Accordingly, the cache data involved in this application in this scenario includes but is not limited to image data, voice data, video data, text data or other data to be cached.

[0039] Next, several method embodiments provided by this application are introduced. Figure 2 , is a flow chart of a cache resource adjustment method provided by an embodiment of the present application. Figure 2 The method is applied to a computer device, including but not limited to a smartphone (e.g., an Android phone, an iOS phone, etc.), a personal computer, a tablet computer, a PDA, a mobile internet device (MID), or a wearable smart device. The method includes the following steps:

[0040] S201 : In response to a resource adjustment instruction, determine used cache resources and allocate cache resources in the computer device.

[0041] The resource adjustment instructions described in this application can be generated by developers based on actual needs, or they can be received from other devices (such as servers or terminal devices). The resource adjustment instructions are used to indicate support for dynamic adjustment of cache resources in the computer device. The cache resources involved in this application can refer to the size of the cache resources, that is, the size of the memory space occupied; it can also refer to the number of cache resources, that is, the number of buffers, which is not limited in this application.

[0042] The used cache resources are the cache resources that have been used in the computer device, that is, data has been cached in the cache resources. The allocated cache resources are the cache resources allocated by the computer device for the current cache scenario, which are usually pre-allocated maximum cache resources that can support the cache scenario. For example, in an encoding scenario, the allocated cache resources can be allocated according to the level of the encoder used in the encoding scenario, and its encoding level will limit the maximum cache resources for different cached data. Correspondingly, in a decoding scenario, the allocated cache resources can be allocated according to the level of the decoder used in the decoding scenario, and its decoding level will limit the maximum cache resources for different cached data, such as the number of decoded picture buffers (DPBs), etc.

[0043] S202: When the used cache resources are less than the allocated cache resources, obtain target information of the data to be cached, where the target information is used to indicate attributes of the data to be cached and / or a scenario associated with the data to be cached.

[0044] This application does not limit the type of data to be cached. It is related to the application scenario corresponding to the cache (referred to as the cache scenario). For example, in the encoding scenario, the data to be cached may be image data, voice data, or video data, etc.; in the non-encoding and decoding scenario, the data to be cached may be video data or text data, etc., which can be found in the previous introduction to the cache data, which will not be repeated here.

[0045] The target information includes but is not limited to at least one of the following: attribute information of the data to be cached, scene information corresponding to the data to be cached, or other information that affects resource regulation, etc. The attribute information is information used to describe the attributes of the data to be cached, which may include but is not limited to the size of the data to be cached. When the data to be cached is video data or image data, the attribute information may also include the resolution of the data to be cached, etc. The scene information is used to indicate the current scene of the data to be cached, and can also be used directly to indicate whether the current scene of the data to be cached has been switched, such as whether the user has changed channels (changed TV channels), or whether the display resolution has been switched, such as from standard display to ultra-high-definition display, etc.

[0046] S203: Allocate and adjust cache resources of the computer device according to the target information.

[0047] By implementing the embodiment of the present application, the computer device responds to the resource adjustment instruction and determines the used cache resources and allocated cache resources in the computer device; when the used cache resources are less than the allocated cache resources, the target information of the data to be cached is obtained, and the target information is used to indicate the attributes of the data to be cached and / or the scenario associated with the data to be cached; and the cache resources of the computer device are allocated and adjusted according to the target information. By adopting the embodiment of the present application, the cache resources in the device can be dynamically adjusted according to the actual cache requirements based on the used cache resources and allocated cache resources in the computer device, thereby avoiding the problem of cache resource waste, thereby saving the memory space occupied by the cache resources, and helping to improve the smoothness of system operation.

[0048] See Figure 3 , is a flow chart of another cache resource adjustment method provided by an embodiment of the present application. Figure 3 The method shown is applied to a computer device, and the method includes the following implementation steps:

[0049] S301. In response to a resource adjustment instruction, register a cache monitoring service in the computer device, where the cache monitoring service is used to monitor and mark the usage status of cache resources in the computer device.

[0050] After determining to start the resource adjustment function, the present application may first register a cache monitoring service in the computer device, such as a cache quantity monitoring service (buffer_count service). The cache monitoring service is used to monitor all cache resources in the computer device and mark the usage status of each cache resource. For example, monitor the number of cache resources actually used, mark the usage status of the used cache resources as used (USED) status, mark the usage status of the unused cache resources as unused (UNUSED) status, etc. The usage status of each cache resource can be adjusted and changed according to the actual usage conditions. This application does not elaborate on the registration implementation of the cache monitoring service, for example, it can be implemented by responding to the registration request of the cache monitoring service.

[0051] S302: Call the cache monitoring service to determine the used cache resources and allocate cache resources in the computer device.

[0052] S303: Determine whether the used cache resources are less than the allocated cache resources.

[0053] The present application can first determine the used cache resources and allocated cache resources in the computer device through the cache monitoring service. Then, it can determine whether the used cache resources are less than the allocated cache resources. When it is determined that the used cache resources are less than the allocated cache resources, step S304 can be continued. Otherwise, the cache resources can be dynamically adjusted according to actual needs, specifically, for example, the corresponding cache resources can be reallocated according to the cache space required for the data to be cached. Furthermore, the present application can incorporate the reallocated cache resources into the dynamic adjustment.

[0054] S304: Acquire target information of the data to be cached, where the target information is used to indicate attributes of the data to be cached and / or a scenario associated with the data to be cached.

[0055] The target information described in this application is used to adjust the cache resources in the computer device, and the target information includes but is not limited to at least one of the following: attribute information of the data to be cached, scene information corresponding to the data to be cached, or other information that affects resource adjustment. Figure 2 The relevant introduction in the embodiments will not be repeated here.

[0056] S305: Allocate and adjust the cache resources of the computer device according to the target information.

[0057] After obtaining the target information, the present application can allocate and adjust the cache resources in the computer device according to the target information. The implementation method of the allocation and adjustment can be found in Figure 4 As shown, Figure 4 The cache resource adjustment method shown includes the following implementation steps:

[0058] S401: If the target information includes scene information corresponding to the data to be cached, determine whether a scene switch occurs in the cached data in the computer device according to the scene information.

[0059] This application does not limit the implementation method for determining the scene switch. For example, this application may perform a consistency comparison based on the scene information of the current data to be cached and the scene information of the last cached data stored in the system to determine whether a scene switch has occurred. Alternatively, this application may directly determine whether a scene switch has occurred based on the indication of the scene information. In this case, the scene information is directly used to indicate whether a scene switch has occurred in the data to be cached.

[0060] Accordingly, if it is determined that no scene switching occurs in the cache resources in the computer device, step S402 is continued to be executed; otherwise, the process can be terminated, or step S403 is continued to be executed.

[0061] It should be noted that scene switching in video data may include, but is not limited to, switching from a single scene to a complex scene, or switching from a static scene to a moving scene. Each scene switching will cause changes in cache resources. Therefore, this application needs to dynamically allocate and adjust cache resources based on the scene switching of the data to maximize the rational use of cache resources, improve cache resource utilization, and avoid resource waste.

[0062] S402: After a preset time period is reached, the redundant cache resources in the computer device are released.

[0063] When the present application determines that no scene switching has occurred in the cache resources in the computer device, after a preset period of time, that is, after the cache resources occupied by the system have reached stability, the present application may first determine the maximum cache resources occupied in actual use. Then, based on the allocated cache resources and the maximum cache resources, the redundant cache resources in this scenario are determined, and finally the redundant cache resources are released. The size of the redundant cache resources described here is the difference between the allocated cache resources and the maximum cache resources, and the usage status of the redundant cache resources is all unused (UNSED). The preset duration is a system-customized duration, which is used to characterize the duration required for the computer device to enter a stable data cache. The duration can be an empirical value set based on user experience, or a numerical value obtained based on a series of experimental data statistics.

[0064] S403: If the target information includes attribute information of the data to be cached, determine whether the attribute of the cached data in the computer device has changed according to the attribute information.

[0065] This application does not limit the implementation method for determining the attribute change. For example, this application can directly determine whether an attribute change has occurred based on the indication of the attribute information. In this case, the attribute information is used to directly indicate whether the attribute of the data to be cached has changed. Alternatively, this application can perform a consistency comparison between the attribute information of the data to be cached and the attribute information of the last cached data stored in the system to determine whether an attribute change has occurred.

[0066] For example, taking the data to be cached as video data, the attribute information of the data to be cached is the resolution of the video data. Accordingly, after determining that a scene switch has occurred, the present application can further determine whether a resolution change has occurred. Specifically, the present application can parse the width field pic_width_in_luma_sample and the length field pic_height_in_luma_sample in the parameter setting (sequence parameter set) in the video data, and compare them with the width field and length field in the previous frame of video data for consistency, thereby determining whether a resolution change, that is, an attribute change, has occurred.

[0067] When it is determined that the attribute of the cache resource in the computer device has changed, step S404 may be continued to be executed; otherwise, step S405 may be executed.

[0068] S404: Allocate new cache resources for the data to be cached according to the attribute information.

[0069] This application can first release all cache resources in the computer device, and then allocate new cache resources to the data to be cached based on the attribute information of the data to be cached. For example, new cache resources can be re-allocated to the data to be cached based on the size or resolution of the data to be cached to meet the current cache requirements of the system. It can also increase or release cache resources based on cache resource requirements when cache resource attributes change.

[0070] S405: Allocate and adjust cache resources in the computer device according to the scenario information corresponding to the data to be cached.

[0071] In a possible implementation, when the required cache resources corresponding to the scenario information are greater than the allocated cache resources, new cache resources may be allocated for the data to be cached based on the required cache resources. At this time, the size of the new cache resources may be the difference between the required cache resources and the allocated cache resources.

[0072] In another possible implementation, when the required cache resources corresponding to the scenario information are less than the allocated cache resources, redundant cache resources in the computer device may be determined based on the required cache resources and the allocated cache resources, where the size of the redundant cache resources is the difference between the allocated cache resources and the required cache resources. Furthermore, the present application may release the redundant cache resources in the computer device.

[0073] It should be noted that the two solutions involved in steps S401-S402 and steps S403-S405 of the present application can be implemented separately or in combination. For example, when the target information described in the present application only includes the scene information corresponding to the data to be cached, the solution of steps S401-S402 can be implemented separately; when the target information includes the attribute information of the data to be cached, the solution of steps S403-S405 can be implemented separately; when the target information includes both the scene information corresponding to the data to be cached and the attribute information of the data to be cached, the solution of steps S401-S405 can be implemented in combination, etc.

[0074] By implementing the embodiment of the present application, the computer device responds to the resource adjustment instruction, registers the cache monitoring service in the computer device in response to the resource adjustment instruction; calls the cache monitoring service to determine the used cache resources and allocated cache resources in the computer device; when the used cache resources are less than the allocated cache resources, obtains the target information of the data to be cached, the target information is used to indicate the attributes of the data to be cached, and / or the scenario associated with the data to be cached; and allocates and adjusts the cache resources of the computer device according to the target information. By adopting the embodiment of the present application, the cache resources in the device can be dynamically adjusted according to the actual cache requirements based on the used cache resources and allocated cache resources in the computer device, thereby avoiding the problem of cache resource waste, thereby saving the memory space occupied by the cache resources, and helping to improve the smoothness of system operation.

[0075] See Figure 5 , is a flow chart of another cache resource adjustment method provided by an embodiment of the present application. Figure 5 The method shown is applied to a computer device, and the method includes the following implementation steps:

[0076] S501. In response to a resource adjustment instruction, register a cache monitoring service in the computer device, where the cache monitoring service is used to monitor and mark the usage status of cache resources in the computer device.

[0077] This application monitors the usage of cache resources in a computer device by a video communication server (VCS) by registering a buffer_count service, and updates the usage status of the cache resources in real time.

[0078] S502: Call the cache monitoring service to determine the used cache resources and allocate cache resources in the computer device.

[0079] S503: Determine whether the used cache resources are less than the allocated cache resources.

[0080] When the application determines that the used cache resources are less than the allocated cache resources, the application may continue to execute step S504; otherwise, the process may end. Figure 3 The introduction of steps S301-S303 in the embodiment will not be repeated here.

[0081] S504: Determine current redundant resources in the computer device according to the used cache resources and the allocated cache resources.

[0082] The present application can determine the current redundant resources in the computer device through the cache monitoring service. The current redundant resources can be determined based on the used cache resources and the allocated cache resources, or can be obtained by multiplying the redundant resources occupied by each cache data by the number of redundant cache data. For example, the current redundant resources can be obtained by multiplying the redundant resources occupied by each frame of video data by the number of redundant frame videos, etc.

[0083] S505: Determine whether the current redundant resources are greater than a preset redundant threshold.

[0084] After obtaining the current redundant resources, the present application may determine whether the current redundant resources are greater than a preset redundant threshold. If so, the process proceeds to step S506. Otherwise, the process may terminate and the cache resource usage status may no longer be monitored through the cache monitoring service. The preset redundant threshold may be a system-defined value, such as an empirical value set based on user experience.

[0085] It is understandable that for smaller cache data, such as video data with a smaller resolution (below 720P), since the originally applied allocated cache resources are not large, the redundant resources are also relatively small. At this time, there is no need to dynamically adjust the cache resources, that is, the dynamic adjustment of cache resources does not bring much benefit. On the contrary, dynamic adjustment of cache resources in this case may cause problems such as reduced cache efficiency due to frequent allocation and release of memory. Therefore, in this case, the present application can set a preset redundancy threshold. When the redundant resources in the computer device are less than the preset redundancy threshold, there is no need to dynamically adjust the cache resources.

[0086] S506: Acquire target information of the data to be cached, where the target information is used to indicate attributes of the data to be cached and / or a scenario associated with the data to be cached.

[0087] In an optional embodiment, before obtaining the target information of the data to be cached, the present application may further determine whether the current cache scenario is stable, specifically determining whether the used cache resources used in the computer device are constant (do not change) after reaching a preset time period. If so, the target information of the data to be cached is obtained; otherwise, the process may be terminated. The used cache resources may be the cache resources used in the computer device after reaching a preset time period, such as the maximum cache resources used in the computer device during the preset time period. The preset time period may be a time period customized by the system, for which details can be found in the relevant description of the aforementioned embodiment.

[0088] S507: Allocate and adjust the cache resources of the computer device according to the target information.

[0089] For the introduction of steps S506-S507 in the embodiment of the present application, please refer to the aforementioned Figure 3 and Figure 4 The relevant introduction in the embodiments will not be repeated here.

[0090] By implementing the embodiment of the present application, the computer device responds to the resource adjustment instruction, registers the cache monitoring service in the computer device in response to the resource adjustment instruction; calls the cache monitoring service to determine the used cache resources and allocated cache resources in the computer device; when the used cache resources are less than the allocated cache resources, obtains the target information of the data to be cached, the target information is used to indicate the attributes of the data to be cached, and / or the scenario associated with the data to be cached; and allocates and adjusts the cache resources of the computer device according to the target information. By adopting the embodiment of the present application, the cache resources in the device can be dynamically adjusted according to the actual cache requirements based on the used cache resources and allocated cache resources in the computer device, thereby avoiding the problem of cache resource waste, thereby saving the memory space occupied by the cache resources, and helping to improve the smoothness of system operation.

[0091] See Figure 6 , is a flow chart of another cache resource adjustment method provided by an embodiment of the present application. Figure 6 The method shown is applied to a computer device, and the method includes the following implementation steps:

[0092] S601: Determine a cache scenario of the computer device.

[0093] The method for determining the caching scene described in this application is not limited. For example, this application can determine it by analyzing the type of data to be cached, or by parsing specific fields in the data to be cached, such as parsing the width field pic_width_in_luma_sample and the length field pic_height_in_luma_sample in the sequence parameter set in the video data to determine the corresponding resolution size scene, etc.

[0094] The cache scenario involved in this application is used to describe the scenario where the cached data is located, which may include but is not limited to decoding scenarios, encoding scenarios, frequent switching scenarios, non-frequent switching scenarios, resolution size scenarios, high-definition scenarios, standard picture quality scenarios, ultra-high-definition scenarios, or other custom classification scenarios.

[0095] S602: Determine whether the cached scene is a preset scene.

[0096] The preset scenario described in this application is a scenario customized by the system. In this embodiment, for example, it is an infrequent switching scenario, that is, the switching frequency of the scenario is less than a preset frequency threshold.

[0097] When the present application determines that the cache scene is a preset scene, step S603 may be continued; otherwise, if it is determined that the current cache scene is in a frequently switched scene, that is, the scene switches frequently, there is no need to dynamically adjust the cache resources, and the process may be ended.

[0098] It should be noted that an alternative implementation of steps S601-S602 of the present application may be to determine the scene switching frequency of the computer device, and then proceed to step S603 if the scene switching frequency is less than a preset frequency threshold; otherwise, the process may terminate. The implementation method for determining the scene switching frequency is not limited. For example, the present application may determine the scene switching frequency by parsing specific fields in the cached data or based on the type of data to be cached, etc., which is not limited by the present application.

[0099] S603: In response to the resource adjustment instruction, determine the used cache resources and allocate cache resources in the computer device.

[0100] S604: Determine whether the used cache resources are less than the allocated cache resources.

[0101] S605: Acquire target information of the data to be cached, where the target information is used to indicate attributes of the data to be cached and / or a scenario associated with the data to be cached.

[0102] S606: Allocate and adjust the cache resources of the computer device according to the target information.

[0103] For the description of steps S603-S606 in the embodiment of the present application, please refer to the aforementioned Figure 2-Figure 5 The relevant introduction in the embodiments will not be repeated here.

[0104] By implementing the embodiment of the present application, the computer device determines the cache scenario of the computer device; when it is determined that the cache scenario is a preset scenario, in response to the resource adjustment instruction, the used cache resources and allocated cache resources in the computer device are determined; when the used cache resources are less than the allocated cache resources, the target information of the data to be cached is obtained, and the target information is used to indicate the attributes of the data to be cached and / or the scenario associated with the data to be cached; according to the target information, the cache resources of the computer device are allocated and adjusted. By adopting the embodiment of the present application, the cache resources in the device can be dynamically adjusted according to the actual cache requirements based on the used cache resources and allocated cache resources in the computer device, thereby avoiding the problem of cache resource waste, thereby saving the memory space occupied by the cache resources, and helping to improve the smoothness of system operation.

[0105] Based on the above embodiments, the following describes the device and equipment embodiments involved in this application.
