[0057] 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 a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0058] In this application, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. The terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0059] The present invention can be used in numerous general-purpose or special-purpose computing device environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multi-processor devices, distributed computing environments including any of the above devices or equipment, and so on.

[0060] An embodiment of the present invention provides a method for online video playback. This method can be applied to a variety of system platforms, and its execution subject can be a computer terminal or a processor of various mobile devices. The method flow chart of the method is as Figure 1 shown and specifically includes:

[0061] S101: Obtain the video information of the video to be played, and obtain each pre-cached local video frame corresponding to the video information and the local video frame information of each local video frame.

[0062] In the embodiment provided by the present invention, when the network condition is relatively good, the user can smoothly watch videos online through the video APP. When the network condition is unstable, watching videos online will become stuck, affecting the user experience. If the user wants to watch videos online at this time, a certain amount of video frames need to be obtained from the devices of other users with better network conditions and played in combination with the local video frames. Therefore, the local device needs to first obtain the video information of the video that the user wants to play, as well as the local video frames that have been pre-cached in the local device memory, and the local video frame information of each local video frame.

[0063] S102: Determine the video frame information of each video frame to be assisted in caching according to the video information and each local video frame information, and generate an assisted caching request for obtaining video frames according to each video frame information.

[0064] In the embodiments provided by the present invention, according to the obtained video information and the information of each local video frame of the video that has been pre-cached, the information of each video frame that needs to request assistance for transmission from other user devices can be obtained. For example, if the video that the user wants to watch has frames 1, 2, 3, 4, and 5, and the local device of the user has pre-cached frames 1 and 3, then frames 2, 4, and 5 need to be requested from other user devices. Therefore, according to the obtained information of each video frame that needs to be requested from other user devices, an assistance caching request for obtaining video frames can be generated.

[0065] S103: Search for user devices within a preset range and obtain each target user device that meets the preset conditions.

[0066] In the embodiments provided by the present invention, the local device searches for user devices within a preset range. Here, the preset range can be a range capable of stably transmitting video frames, or user devices at a preset distance from the local device. One or more target user devices that can perform video frame transmission and meet the preset conditions are obtained within the preset range.

[0067] Specifically, as Figure 2 shown, the step of searching for user devices within a preset range and obtaining each target user device that meets the preset conditions includes:

[0068] S201: Determine each user device within the distance where Bluetooth can stably transmit as a device to be detected.

[0069] The local device and other user devices for assisting in transmission can transmit video frames through Bluetooth. When the user enters an environment with poor network or the user's current network fluctuates greatly and it is impossible to smoothly watch the video, the video application of the local device can initiate a search for users within a certain range around, and the range is locked within the distance where Bluetooth can stably transmit. Each user device within the distance where Bluetooth can stably transmit is determined as a device to be detected.

[0070] S202: Send a network detection request to each of the devices to be detected, so that each of the devices to be detected returns detection network authorization information indicating whether to agree or disagree to detect the network status according to the network detection request.

[0071] After detecting the devices to be detected with online users having the same video application within the range where Bluetooth can perform stable transmission, a network detection request is sent to each device to be detected. The search for other users and the judgment of the network status require the authorization of other users. The device to be detected returns detection network authorization information indicating agreement or disagreement to detect the network status according to the network detection request. The user device can indicate authorization or non-authorization to detect the network by turning on or off the authorization switch in the application background, or can also select to agree or disagree to authorize the detection network according to the authorization pop-up window.

[0072] S203: When receiving the detection network authorization information indicating that each of the devices to be detected agrees to detect the network status, detect whether the network status of each of the devices to be detected meets the preset network transmission conditions, and determine each user device that meets the network transmission conditions as the target device.

[0073] When the local device receives the detection network authorization information indicating that other user devices, i.e., the devices to be detected, agree to detect the network status, the local device starts to detect the network status of the device to be detected. If the network status of the device to be detected is good and can support the caching and transmission of video frames, then the network status of the device to be detected meets the preset network transmission conditions, and the device to be detected is determined as the target device.

[0074] Among them, meeting the network transmission conditions, that is, having a good network status, can specifically mean that the network reaches a certain download rate value, and this download rate value can be determined by the user according to the situation and is not specifically limited here.

[0075] Applying the embodiment provided by the present invention, in the case where other user devices agree to authorize the detection of the network, the user devices with good detected networks are the target user devices. The network is detected only when other user devices authorize the search and detection of the network, so that the user device is not randomly detected by other devices, ensuring the security of the device. Moreover, the user devices with good networks within the distance where Bluetooth can perform stable transmission are detected as the target devices, ensuring stable transmission between the local device of the video frame and the target device.

[0076] S104: Send the assistance caching request to each of the target user devices, so that each of the target user devices returns each video frame corresponding to each video frame information with the consent of the user using the device.

[0077] In the embodiments provided by the present invention, after detecting each target device that can assist in video frame caching, an assistance caching request is sent to the target video. After receiving the assistance caching request, the user of the target device authorizes whether to agree to assist in caching the video frames. In the case of agreeing to the authorization, the target device caches the video frames corresponding to each video frame information according to the assistance caching request.

[0078] It should be noted that for the user to assist in caching video frames, the user needs to have the same video player as the local device, that is, the same video application. After the user authorizes and agrees to cache the video frames, it can be cached in the foreground of the opened video application or in the background.

[0079] S105: Determine each target video frame in each of the video frames, and parse each target video frame and each local video frame to implement online playback of the video.

[0080] In the embodiments provided by the present invention, after the local device obtains the video frames returned by each user device according to each video frame information through Bluetooth transmission, it determines each target video frame for playback among the obtained video frames, combines each target video frame with each local video frame for parsing, and plays according to the normal process.

[0081] Based on the embodiments provided by the present invention, when performing online video playback, obtain the video information of the video to be played, and obtain each pre-cached local video frame corresponding to the video information and the local video frame information of each local video frame; according to the video information and each local video frame information, determine the video frame information of each video frame to be assisted in caching, and generate an assistance caching request for obtaining video frames according to each video frame information; search for user devices within a preset range, and obtain each target user device that meets the preset conditions; send an assistance caching request to each target user device, so that each target user device returns each video frame corresponding to each video frame information when the user of the user device agrees to authorize; determine each target video frame in each video frame, and parse each target video frame and each local video frame to implement online playback of the video.

[0082] Applying the embodiments provided by the present invention, in the case of unstable network status, it is possible to assist in obtaining some video frames from other user devices, combine and parse them with the locally pre-cached video frames, implement video playback under complex networks, ensure the stability of the user's online video viewing, and effectively improve the user's viewing experience.

[0083] Among them, the determination of each target video frame in each of the video frames includes:

[0084] Clear each video frame that meets the preset damage conditions among the various video frames, obtain the preprocessed video frames, and perform a deduplication operation on each of the preprocessed video frames to obtain each target video frame.

[0085] Specifically, after obtaining each of the returned video frames, some damaged video frames can be cleared first. The damage conditions of the video frames can be set according to the characteristics of the video frames. For example, the video frames cannot be displayed, there are display errors, etc. Then, a deduplication operation is performed on the remaining video frames. Since the local device simultaneously sends requests to obtain video frames to multiple other user devices, the video frames transmitted back by each target device may be repeated. Therefore, a deduplication operation needs to be performed on each of the transmitted-back video frames, and finally, each target video frame that can be used for video playback is obtained.

[0086] It should be noted that the local device receives in real time each video frame transmitted back by other user devices, performs a deduplication and cleaning operation on each video frame, and then combines the obtained target video frames with the local video frames for parsing and playback.

[0087] It also should be noted that the player in the video application needs to be modified. When there are frames 1, 2, 3, 4, 5 in a video, if the player integrates according to the video frames transmitted back by other devices and the local video frames and only obtains frames 1, 2, 4, 5, the player can play normally, and the connection between frame 42 and frame 4 can be correct, without any phenomenon of screen freeze or black screen, ensuring the correct display of the playback content.

[0088] Applying the embodiments provided by the present invention, damaged video frames and duplicate video frames are cleared among the video frames returned by multiple user devices, and each high-quality target video frame is obtained, thereby improving the quality of video playback.

[0089] As Figure 3 shown, in the embodiments provided by the present invention, optionally, it further includes:

[0090] S301: Send an authorization request to the user asking whether to agree to pre-cache the video.

[0091] The video application in the local device requires the user to perform an authorization operation in advance for the pre-caching process of the video. Only when the user authorizes the pre-caching process can the pre-caching operation be performed. If the user refuses the authorization, the pre-caching operation is not allowed.

[0092] S302: If the return information indicating that the user agrees to the authorization request is received, obtain the historical viewing record of the video.

[0093] S303: Pre-cache each key frame of the video using an intelligent recommendation algorithm according to the historical viewing record to obtain each local video frame of the video.

[0094] If the user agrees to pre-caching the video in advance and the network is good, the user enters the video application to watch the video. While watching the video, without affecting the user's online video viewing experience, based on the intelligent algorithm recommendation and the historical viewing history of the video, some key frames of the video are pre-cached for the user to obtain the local video frames of the video.

[0095] By applying the embodiment provided by the present invention, some video frames can be automatically cached when the network condition is good through user authorization, which can reduce the need to assist in caching video frames with other user devices when the network is unstable, and effectively improve the efficiency of video playback.

[0096] In the embodiment provided by the present invention, optionally, it also includes:

[0097] Detect the playback progress of the video corresponding to each of the local video frames and the cache time of each of the video frames; if the video corresponding to the local video frame has been completed, or the cache time of the video frame exceeds a set threshold, clear the local video frame.

[0098] Specifically, Figure 4 As shown, local video frames are pre-cached in the video application of the local device, and the local device detects in real time the playback progress of the video corresponding to each local video frame and the caching time of the video frame; if the user has finished playing the video content corresponding to the local video frame within a set time limit, the local video frame content pre-cached in the video application of the local device is directly cleared after the user finishes watching; if the corresponding video is still not played after the preset time limit, the application actively clears the pre-cached local video frame.

[0099] By applying the embodiment provided by the present invention, video frames that have been played or have not been played for a long time are cleaned up regularly to release device memory, which is beneficial to improving device performance and video playback experience.

[0100] like Figure 5A data flow diagram for online video playback is shown. When user A plays a certain video online and the network condition is unstable, a request for the required video is generated based on the video information and the information of each local video frame that has been pre-cached locally for this video, and the request for the required video is sent to the terminal applications of other users via the Bluetooth of user A. After the terminal applications of other users receive the request for the required video sent by the terminal application of user A via their own Bluetooth, they obtain the information of the video frames required by user A from the server according to the information of each required video frame corresponding to the request for the required video by user A. The server returns each video frame required by user A to the terminal applications of other users according to the received information of the video frames required by user A. After the terminal applications of other users receive each video frame required by user A, they send each video frame to the terminal application of user A via their own Bluetooth. The terminal application of user A receives each video frame returned by the terminal applications of other users via the Bluetooth of user A.

[0101] As Figure 6 A method flow diagram for online video playback is shown. When a user plays a video in the video application of a local device, the local device continuously judges its own network condition in real time. When the network is in a good condition, while playing the video normally in the video application, some key frames of the video are recommended to be pre-cached according to the video information of the currently played video and the historical viewing records through an intelligent algorithm; when the network is in a poor condition or the network fluctuates greatly and is unstable, a search for other user devices within a certain range around that have the same application and whose users are online is initiated in the video application. The search for other user devices can only be carried out when the users of the other user devices consent to the search. The network conditions of the other user devices with online users found are judged. Similarly, the network condition of the user device corresponding to the user can only be judged when the user of the other user device consents to the network detection. If the user devices found are also in an unstable network state, no request processing operation is performed. If the network condition of the user device is good, a request to assist in caching video frames is sent to the user device. Here, the user device can be a single user device or multiple user devices. When the user device receives the request to assist in caching video frames, an authorization confirmation operation is performed to judge whether the user of the user device authorizes to assist in caching video frames. If the user of the user device does not authorize, the user device does not perform subsequent processing operations for assisting in caching video frames. If the user of the user device authorizes, the user device pre-caches each video frame corresponding to the request to assist in caching video frames and returns each video frame to the local device. The video application of the local device performs internal parsing processing based on the returned video frames and the local video frames pre-cached in the local device and plays them in the video application of the local device.

[0102] The specific implementation processes and their derivative methods of the above-mentioned various embodiments are all within the protection scope of the present invention.
