[0025] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0026] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0027] With the development of science and technology, the functions and applications of electronic devices such as mobile phones are becoming more and more abundant. At the same time, with the increasing power of artificial intelligence (AI) algorithms, short video applications (APP) are becoming more and more popular with users due to their many advantages: watching in fragmented time, understanding your hobbies, and automatically pushing videos that you are interested in. More and more users spend more time on short video APPs than on traditional long video APPs. Watching short videos in free time has become the most common hobby of the majority of electronic device users.

[0028] In the related art, many users like to watch short videos while on airplanes, high-speed trains, or on the subway when commuting to get off work. At this time, due to the lack of network, or the network but unstable signal, many short videos cannot be successfully played or played smoothly. In addition, short videos consume a lot of traffic. Most users' operator packages have a traffic limit. Long-term use of cellular data traffic to watch short videos will also cause the electronic device to have insufficient traffic, and extra money will be needed to recharge the traffic. It can be seen that the related art cannot achieve a balance between smooth short video playback and low cellular data traffic overhead, and cannot meet users' diverse needs for playing short videos on electronic devices.

[0029] In order to solve the above technical problems, the embodiments of the present application provide a video caching method, device, electronic device and storage medium.

[0030] The video caching method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0031] It should be noted that the video caching method provided in the embodiment of the present application is applicable to electronic devices. In practical applications, the electronic devices may include: mobile terminals such as smart phones, tablet computers, personal digital assistants, etc., and the embodiment of the present application does not limit this.

[0032] Figure 1 is a flow chart of a video caching method provided by an embodiment of the present application, such as Figure 1 As shown, the method may include the following steps: step 101, step 102 and step 103, wherein:

[0033] In step 101, a first input from a user is received.

[0034] In step 102, in response to a first input, the size of a video pre-cached from a network and an expiration time of the cached video are set.

[0035] In the embodiment of the present application, the video cached from the network can be a short video, a medium-length video, or a long video. For ease of understanding, the following description will be made by taking a short video as an example.

[0036] In order to ensure that the electronic device can play short videos smoothly in various network environments, the electronic device can support users to cache some short videos from the network to the local electronic device in advance.

[0037] In an embodiment of the present application, a user can set the size of the video cached from the network and the expiration time of the cached video by inputting a first input on the electronic device, wherein the first input can be a gesture-related input such as a click input, a sliding input, or a text input, or can be a voice input.

[0038] In some embodiments, the electronic device may provide a video cache setting interface, wherein the video cache setting interface may include: a cached video size setting control and a cached video expiration time setting control, and the user sets the video size cached from the network and the cached video expiration time by making a first input to the above controls.

[0039] In one example, a short video cache setting control can be added to the video playback interface of the electronic device. When the user goes out or is about to leave the WiFi area, the user can click this control. When the electronic device detects that the user clicks this control, it displays the following Figure 2 The video cache setting interface shown allows users to select the size of the target cached video and the cached video expiration time (cached short videos occupy memory and are set to be automatically deleted after a period of time to free up memory). Users can select the corresponding video cache size and video expiration time according to their needs, or they can customize them. After the user has checked, the electronic device can automatically cache videos of the corresponding size for the user according to the user's preference for watching short videos, and start the timer to automatically delete the corresponding short video after the time point set by the user.

[0040] In an embodiment of the present application, in order to reduce the storage space occupancy rate of the electronic device, the cached videos in the electronic device that have reached the video expiration time can be deleted to release the memory occupied by these videos to avoid long-term occupation of the storage space of the electronic device.

[0041] In another example, one may use Figure 3 The hardware and software combination shown in the figure enables electronic devices to pre-cache short videos, such as Figure 3 As shown, the electronic device may include: a processor, a memory and a timer, wherein a video recommendation algorithm and a short video APP are run in the processor, the video recommendation algorithm is an algorithm formed according to the user's preferences when watching short videos, the timer is used to notify the memory to delete the cached video according to the short video expiration time set by the user (also known as the video release time) after the time is up, and the memory is used to store the cached video, which can be specifically a memory. After the user completes the cache setting, the processor will cache the video of the corresponding size to the memory in the background according to the user's settings. It will start in WiFi mode by default. In non-WiFi mode, the user will be reminded whether to use traffic to download. After the download is completed, the main page of the electronic device will prompt the user that the download has been completed. After the video is downloaded, when the user opens the corresponding short video APP, the electronic device will detect the network status of the electronic device, and adopt a short video playback strategy that matches the current network status according to the current network status of the electronic device.

[0042] In step 103, according to the set video size and cache video expiration time, the video is downloaded from the network for pre-caching.

[0043] As can be seen from the above embodiments, in this embodiment, the user can set the size of the video to be pre-cached from the network and the expiration time of the cached video. According to the set video size and expiration time of the cached video, the video is downloaded from the network for pre-caching, so that when the user subsequently uses the electronic device to watch the video, the electronic device can read the cached video from the electronic device in a timely and appropriate manner for playback based on the network status of the user's environment, so as to achieve a balance between smooth playback of short videos and low overhead of cellular data traffic, and can meet the diverse needs of users for playing short videos on electronic devices.

[0044] In another embodiment provided by the present application, the video caching method provided can be Figure 1 After step 103 in the illustrated embodiment, the following steps are added (not shown in the figure): step 104, step 105 and step 106, wherein:

[0045] In step 104, when the network state of the electronic device is a cellular network connection state, a second input of the user is received.

[0046] In the embodiment of the present application, the second input may be a click input, for example, a click input to a video playback control.

[0047] In step 105, in response to the second input, a target push ratio of cached videos to network downloaded videos is determined.

[0048] In the embodiment of the present application, the target push ratio carries the proportion of cached videos and the proportion of network downloaded videos in the videos pushed to the user.

[0049] In some embodiments, the target push ratio of cached videos to network downloaded videos can be determined according to the playback mode selected by the user. Accordingly, the above step 105 may include the following steps (not shown in the figure): sub-step 1051 and sub-step 1052, wherein:

[0050] In sub-step 1051, in response to the second input, a user-selected play mode is determined.

[0051] In an embodiment of the present application, in order to ensure that the electronic device can smoothly play short videos while reducing the cellular data traffic overhead in a cellular network environment, the electronic device can support users to set multiple play modes. For example, when the network state of the electronic device is a cellular network connection state, a play mode selection interface is displayed, wherein the play mode selection interface includes multiple play mode selection controls, and different play mode selection controls correspond to different play modes; a user's selection input for a play mode selection control is received, and in response to the selection input, the user's selected play mode is determined. The selection input can be a click input or a slide input.

[0052] In one example, when a user opens a short video app, if it is detected that the app is in a cellular network connection state, the following is displayed: Figure 4 The playback mode selection interface shown asks the user whether to enter free traffic mode, low traffic mode or normal traffic mode.

[0053] In sub-step 1052, the target push ratio of cached videos and network downloaded videos is determined according to the playback mode; when the playback mode is the free traffic mode, the target push ratio is 1:0; when the playback mode is the low traffic mode, the target push ratio is M:N, wherein M>N, and M and N are both positive integers; when the playback mode is the normal traffic mode, the target push ratio is 1:1.

[0054] When the user selects the free-traffic mode for playback, the target push ratio is 1:0. That is, after the user selects the free-traffic mode, the short video APP will only push videos from the cached videos for the user to watch, and will not download new videos.

[0055] When the playback mode selected by the user is the low-traffic mode, the target push ratio is M:N, where M>N, and M and N are both positive integers. That is, after the user selects the low-traffic mode, the number of cached videos in the short videos pushed to the user for playback is greater than the number of videos downloaded from the network in real time.

[0056] When the user selects the normal traffic mode, the target push ratio is 1:1. That is, when the user selects the low traffic mode or the normal traffic mode, the electronic device will simultaneously download and push new videos while pushing cached videos to the user (for example, some users like to pay attention to first-hand news or messages). Depending on the selected mode, the ratio of pushed new videos to cached videos is different. For example, in the low traffic mode, this ratio is 1:5, while in the normal traffic mode, this ratio is 1:1.

[0057] In some embodiments, in addition to the above three playback modes, at least one of the following two playback modes may also be included: a mode in which the target push ratio of cached video to network downloaded video is P:Q, P<Q, and P and Q are both positive integers, and a mode in which the target push ratio of cached video to network downloaded video is 0:1.

[0058] In step 106, according to the target push ratio, cached videos of a first ratio are read from the electronic device and videos of a second ratio are downloaded from the network for playback.

[0059] In some embodiments, considering that the network speed of the cellular network may fluctuate, for example, at different times in the same location, the network speed may fluctuate, or as the electronic device moves from one location to another, the network speed may also fluctuate. In view of this situation, during the video playback process, the network speed may be detected in real time, and the push ratio of the cached video may be dynamically adjusted according to the network speed. Accordingly, after the above step 106, the following steps (not shown in the figure) may be added: step 107, wherein,

[0060] In step 107, the download rate of the cellular network is detected. When it is detected that the download rate of the cellular network is lower than the first preset rate threshold, the push ratio of the cached video is increased until it is detected that the download rate of the cellular network is not lower than the first preset rate threshold, and the push ratio of the cached video is reduced to the first ratio.

[0061] That is, when the network rate is low, the proportion of cached videos in the videos pushed to users is increased. When the network rate returns to normal, the proportion of cached videos in the videos pushed to users is reduced to the first proportion to ensure smooth playback of the video during playback.

[0062] In the embodiment of the present application, the first preset rate threshold may be the minimum download rate required for smoothly downloading the video in a cellular network connection state.

[0063] For example, in low traffic mode or normal traffic mode, when the electronic device detects that the download rate of the cellular network is low (a low download rate can easily cause freezes when downloading new videos), it will gradually increase the push ratio of cached videos until the download rate of the cellular network returns to normal, and then gradually return to the previous push ratio of new videos and cached videos.

[0064] It can be seen that in the embodiment of the present application, when the user is in an environment where there is only a cellular network but no wireless network, the electronic device can, according to the user's needs, push short videos pre-cached in the electronic device to the user, and simultaneously download and push new videos to ensure that the electronic device can play short videos smoothly while saving the cellular data traffic overhead of the electronic device.

[0065] In another embodiment provided in the present application, the provided video caching method can be Figure 1 After step 103 in the illustrated embodiment, the following steps are added (not shown in the figure): step 108, wherein:

[0066] In step 108, when the network status of the electronic device is a wireless network WiFi connection status and the WiFi download rate is lower than a second preset rate threshold, the cached video is read from the electronic device for playback until the WiFi download rate is no lower than the second preset rate threshold, then the reading of the cached video in the electronic device is stopped and the video is downloaded from the network for playback.

[0067] In the embodiment of the present application, the second preset rate threshold may be the minimum download rate required for smoothly downloading the video in a WiFi connection state.

[0068] In one example, when a user opens a short video APP, the electronic device detects in real time whether the local area is connected to WiFi. If it is detected that WiFi is connected and the download rate of WiFi is normal (that is, the download rate of WiFi is not lower than the second preset rate threshold), the cached video will not be played, but the new video will continue to be downloaded through WiFi for the user to watch. When it is detected that the download rate of WiFi is lower than a certain download rate (a low download rate of WiFi can easily cause freezes when downloading new videos), a part of the cached video will be called out for the user to watch until the download rate of WiFi returns to normal, and then the new video will be downloaded again for the user to watch. The cached video that has been watched will be automatically deleted after 1 minute (to prevent users from watching it repeatedly), freeing up storage space for the electronic device.

[0069] It can be seen that in the embodiment of the present application, when the network status of the electronic device is a WiFi connection status but the WiFi download rate is low, the electronic device may experience a lag problem when downloading videos from the network. In order to ensure that the electronic device can play short videos smoothly for users, the cached video in the electronic device can be read for playback until the WiFi download rate returns to normal.

[0070] In another embodiment provided in the present application, the provided video caching method can be Figure 1 After step 103 in the illustrated embodiment, the following steps are added (not shown in the figure): step 109, wherein:

[0071] In step 109, when the network status of the electronic device is not connected to the network, the cached video is read from the electronic device for playback.

[0072] It can be seen that in the embodiment of the present application, when the network status of the electronic device is not connected to the network, the electronic device cannot access the Internet. In order to ensure that the electronic device can play short videos smoothly for users, the cached video in the electronic device can be read for playback.

[0073] In summary, in the embodiments of the present application, when playing short videos, the electronic device can adopt different playback strategies according to the different network states of the user's environment. When the user is in an environment without a network, or with a network but an unstable network signal, the short video pre-cached in the electronic device can be played to ensure that the electronic device can play the short video smoothly. When the user is in an environment with only a cellular network and no wireless network, the electronic device can, according to the user's needs, push the short video pre-cached in the electronic device to the user, and also simultaneously download and push new videos to ensure that the electronic device can play the short video smoothly while saving the cellular data traffic overhead of the electronic device. It can be seen that the prior art can achieve a balance between smooth playback of short videos and low overhead of cellular data traffic, and can meet the diverse needs of users for electronic devices to play short videos.

[0074] The video caching method provided in the embodiment of the present application can be executed by a video caching device. In the embodiment of the present application, the video caching device provided in the embodiment of the present application is described by taking the video caching method executed by the video caching device as an example.

According to the set video size and expiration time of the cached video, the video is downloaded from the network for pre-caching, so that when the user subsequently uses the electronic device to watch the video, the electronic device can read the cached video from the electronic device in a timely and appropriate manner for playback based on the network status of the user's environment, so as to achieve a balance between smooth playback of short videos and low overhead of cellular data traffic, and can meet the diverse needs of users for playing short videos on electronic devices.
