Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below.
In the related art, as described in the background art, when preloading is performed by loading a data size with a fixed time length, a client needs to analyze and process a video, so that the client has a complicated operation flow for executing preloading.
In view of the above, the present disclosure provides a video preloading method.
Fig. 1 is a schematic diagram of an applicable scenario in the embodiment of the present disclosure. The application scenario includes a terminal 10, a service server 11, and a video server 12, and the service server and the video server may together form a server. The terminal is provided with a client, and a user performs video operations such as browsing, downloading and uploading videos through the client.
Firstly, a client can send an acquisition request of a video page to a service server based on user operation, the service server 11 receives the acquisition request of the video page, then, according to a preset preloading duration, the preloading data content of each video in the video page is determined, and then, the client is instructed to complete the preloading operation.
For example, the service server 11 may notify the client of the URL of the preloaded data content of each video, where the URL usually points to the video server, and then the client accesses the video server through the URL to download the corresponding preloaded data content from the video server, thereby completing the preloading operation.
Therefore, in the disclosure, the server determines the content of the preloaded data of each video in the video page according to the preset preloading duration, and instructs the client to complete the preloading operation of each video. The client only needs to download the corresponding preloaded data content according to the indication of the server, and does not need to analyze and process the video, so that the process of determining the preloaded data content by the client can be simplified.
Referring to fig. 2, the present disclosure discloses a method of video preloading, the method comprising:
a client application is opened in the terminal in response to a user operation. The client application displays an operation interface of the client. The operation of responding to the user operation, for example responding to the user request to find the page, is performed in the operation interface. The discovery page may include a plurality of videos therein. Thus, in step 201, the client sends an acquisition request of the video page to the server. The acquisition request may include a page identifier and a user identifier.
In step 202, after receiving an acquisition request for acquiring a video page sent by a client, a server determines preloaded data contents of videos in the video page according to a preset preloading duration. Then, in step 203, the server instructs the client to complete the preloading operation on each video according to the preloaded data content of each video.
Based on the embodiment of the application, the server determines the pre-loading data of each video according to the preset pre-loading duration, so that the operation of the client for completing the video pre-loading can be simplified, and the determination of the pre-loading data content does not need to be performed by the client, thereby reducing the performance requirement on the client. In addition, based on the data of loading the preset preloading duration, the client can be ensured to play, the fluency of playing the video can be ensured, and the playing start is not blocked.
In one embodiment, when the server determines the preloaded data content, the server has more information to refer to than the client, so that the determination of the preloaded data content can be determined according to actual service needs. For example, as to how to determine the preloaded content of each video in the video page according to the preset preloaded time length, in one embodiment, one of the following two ways may be implemented:
mode 1), analyzing the videos to obtain the byte number of each frame of each video, and determining the pre-loaded data content of each video according to the byte number of each frame and the preset pre-loaded duration.
For example, if the preset loading duration is 5 seconds, the frame rate is 10, and the number of bytes per frame is a, the total preloaded data amount is 50A. Thereby determining the preloaded data content.
Mode 2), analyzing the videos to obtain the offsets of the key frames of the videos and the time stamps, and determining the offset of the key frame with the time stamp closest to the preset preloading duration as the preloading data content of the corresponding video.
For example, if the preload duration is 5 seconds, the timestamp of the key frame is 4.9 seconds, and the timestamp of the next key frame is 5.1 seconds, then it can be determined that the timestamp of the key frame of 4.9 seconds is closest to the preload duration. Therefore, the offset of the key frame of 4.9 seconds is determined to be the data amount of the preloaded data content, so as to determine the preloaded data content.
Through the two modes, the pre-loaded content of each video can be conveniently determined according to the preset pre-loading duration.
In regard to the instruction performed in step 203 to instruct the client to complete the preloading operation on the videos, in one embodiment, the instruction may be performed to send response information to the client, so that the client obtains corresponding preloaded data contents according to the response information; wherein, the response message may include one of the following three messages:
1) and the Uniform Resource Locators (URLs) of the videos, so that the client can access and download corresponding preloaded data contents according to the URLs.
2) And the response information comprises the URL of each video and the data size corresponding to each URL.
In this embodiment, the client may access and download the corresponding preloaded data content according to the URL, and perform the preloading operation according to the data size of each preloaded data content, so that the client can know the downloaded data size. For example, the size of the data volume is 10M (megabyte), and the client may stop the preloading operation after downloading the 10M data volume by connecting the port with the server.
3) And the response information comprises the pre-loaded data content of each video.
In this embodiment, the server may directly feed back the determined preloaded data content to the client, and the client receives the data to complete the preloading operation.
For example, the discovery page shown in fig. 3 includes video 1, video 2, video 3, and video 4. After the server receives the obtaining request for accessing the video page shown in fig. 3, the server may parse out that the page includes 4 videos as described above. And then, the server determines the pre-loading data contents of 4 videos in the video page according to a preset pre-loading time length, and instructs the client to finish the pre-loading operation of the 4 videos in the page according to the determined pre-loading data contents of the 4 videos. For example, the server may determine URLs of the 4 videos, and send response information carrying the URLs of the videos to the client, so that the client completes the preloading operation of the corresponding videos.
In one embodiment, network traffic is saved in order to assist the client in completing more accurate preloading operations. In the embodiment of the application, the preloaded data content can be determined according to the preset preloaded time length, and the preloaded data content of each video in the video page can be determined by further combining with the video related information on the basis of adopting the preset preloaded time length. Wherein the video-related information may include at least one of: playing heat, click quantity, uploading time, estimated user preference and the like. In implementation, the accuracy of determining the preloaded data content can be improved as much as possible, and information capable of meeting the requirements of the client can be used as video related information and applied to the embodiment of the disclosure.
Based on the video related information, the server side can flexibly determine the preloaded data content based on the information such as the playing heat, the click rate and the like. The click rate of the video can reflect the quality of the video and the preference of a user on a certain level, the higher the click rate of the video is, the higher the possibility that the video is clicked is, the preloaded data content can be in direct proportion to the click rate of the video when the preloaded data content is determined, and therefore, for the video with high click rate, a client can load more, so that the user experience can be smooth when the video is played.
Some descriptions are made herein on how to combine the video-related information, and it should be understood that these descriptions are only used to better understand the technical solutions provided by the embodiments of the present disclosure, but not used to limit the solutions of the embodiments of the present disclosure. In one implementation, the means for incorporating the video-related information includes one of:
in the operation mode 1, before the pre-loading data content of each video is determined according to the preset pre-loading duration, videos of which the video related information does not meet the preset video loading condition are filtered;
for example, 10 videos are included in the page, and 7 videos do not satisfy the preset video loading condition, the client may only preload the remaining three videos. And the rest 7 videos are not preloaded, so that the bandwidth occupation and the traffic consumption caused by the preloading operation of the 7 videos which do not meet the conditions are avoided.
Based on the preset video loading conditions, which videos in the page are probably not clicked can be estimated, and for the videos which are not clicked, the flow can be saved by not performing preloading operation. In one embodiment, the preset video loading condition includes at least one of the following: the playing heat is greater than the preset heat, the click rate is greater than the preset click rate, the uploading time meets the requirement of a preset time period, and the estimated user preference is greater than the preset preference.
For example, when the click volume of a video is less than a preset click volume, the video may be filtered out without determining to preload data content. Therefore, whether preloading is carried out can be determined according to the preset video loading conditions, and the downloading of video contents which cannot be played at the client side is avoided by filtering videos which cannot be browsed by a user basically, so that the purposes of saving network flow and processing resources of the server side and the client side are achieved.
An operation mode 2, after the pre-loaded data content of each video is determined according to the preset pre-loading duration, adjusting the data volume of the pre-loaded data content by adopting the video related information;
for example, when the popularity of a certain video is high, it indicates that the viewing volume of the video is large, so the data volume of the preloaded data content of the video can be increased a little. The watching of the user is prevented from being influenced.
And in the operation mode 3, before the pre-loading data content of each video is determined according to the preset pre-loading time length, the preset pre-loading time length is adjusted by adopting the video related information.
For example, before determining the preloaded data content of each video according to the preset preload duration, the upload time of a certain video is relatively new, so that the video is arranged above a video page, and the play amount is higher than that of other videos, so that the preset preload duration of the video can be adjusted to be longer, and the user experience is smoother.
Therefore, the server side can flexibly determine the pre-loaded content of each video by combining the related information of the video.
In one embodiment, in the foregoing operation mode 2, the adjusting the data amount in the preloaded data may be implemented by determining an adjustment amount of the data amount of the preloaded data content according to a first positive correlation between the adjustment amount and a value corresponding to an information type and/or at least one information type in the video related information; adjusting the data volume of the preloaded data content according to the determined adjustment volume; in the first positive correlation, the adjustment amount is proportional to the magnitude of the information of each information type, and when the video related information includes a plurality of information types, the adjustment amount is proportional to the type of the information type included in the video related information.
For example, the playing heat, the click rate, the uploading time, and the estimated user preference in the video related information are each an information type, and the information of each information type has a corresponding numerical value.
The influence of different information types on the adjustment amount can be different, for example, the estimated user preference can better represent the possibility that the user at the client side watches the corresponding video, and can describe the requirement of the user better than the uploading time, so that the influence of the preference of the user on the adjustment amount is larger than that of the long uploading time.
In order to measure the influence of the values of various types of information on the adjustment quantity, the values of various types can be normalized so as to compare the influence of the values of various types on the adjustment quantity on the same scale. When the adjustment amount is determined based on the numerical value, the larger the adjustment amount.
In a word, the determined data size of the preloaded data content is in direct proportion to the playing popularity, the click rate, the uploading time and the estimated user preference. When multiple types of information are included in the video-related information, the adjustment of the data amount with respect to a single type of information is larger. For example, when the video related information only includes the playing popularity, the adjustment amount is a, and on the premise that the playing popularity is the same as the value of the playing popularity, when the playing popularity and the click rate are included, the adjustment amount is B, where B is greater than a.
Therefore, in the embodiment of the application, the data volume of the preloaded data content can be adjusted according to the first positive correlation between the adjustment volume and the value corresponding to the information type and/or at least one information type in the video related information, so that the preloaded data content can be determined more flexibly, and the preloaded data content can be determined according to the requirement.
Similarly, in an embodiment, as to how to adjust the preset preload duration according to the related information of the video in the foregoing operation mode 3, the adjustment duration of the preset preload duration may be determined according to a second positive correlation between the adjustment duration and the related information of the video; adjusting the preset preloading duration according to the determined adjustment duration; in the second positive correlation, the adjustment duration is in direct proportion to the magnitude of the information of each information type of the video related information, and when the video related information includes multiple information types, the adjustment duration is in direct proportion to the type of the information type included in the video related information.
Similarly, different types of information may have different effects on the adjustment duration, e.g., the estimated user preference may have a greater effect on the adjustment duration than the upload time.
The influence of the value of the information on the adjustment duration is that the larger the value is, the larger the influence on the adjustment duration is.
Therefore, the pre-loading duration of the preset video can be adjusted according to the condition that the adjustment duration is in direct proportion to the numerical value of the information of each information type of the video related information.
Accordingly, how the client completes the preloading operation can be shown in fig. 4, which includes the following steps:
step 401: and sending the acquisition request of the video page to a server.
Step 402: and completing the preloading operation according to the instruction of the server, wherein the instruction is sent by the server after determining the preloading data content of each video of the video page, and the preloading data content is determined by the server according to the preset preloading duration.
Has the beneficial effects that: the client sends a video page amount acquisition request to the server, and after the server determines the pre-loaded data content of each video according to the preset pre-loading duration, the client receives an instruction of the server for completing the pre-loading operation. The client does not need to determine the pre-loaded data content of each video, so that the process that the client completes the pre-recording operation can be simplified, the requirement on the performance of the client is lowered, the pre-loaded data content of each video is determined according to the preset pre-loading duration, and the problem that the pre-loaded data content is too much or too little is solved.
In an embodiment, the indication is response information sent by the server, where the response information includes a uniform resource locator URL of each video, or the response information includes the URL of each video and a data size corresponding to each URL, or the response information includes preloaded data content of each video.
Therefore, the client can perform preloading operation according to the response information sent by the server.
Of course, determining which videos to preload may be performed by the server or the client. When the client determines which videos to preload, the client may also filter out videos that do not need to be preloaded according to the preset video loading condition. In implementation, the client may filter out the preloaded data content of the video that does not satisfy the preset video loading condition before step 402. The details of how to filter the waste water are described above and will not be described herein. It should be noted here that, when the client completes filtering, the preset video loading condition includes at least one of the following: the playing heat is greater than the preset heat, the click rate is greater than the preset click rate, the uploading time meets the requirement of a preset time period, the estimated user preference is greater than the preset preference, and when the response information comprises the data volume corresponding to each URL, the data volume of the preloaded data content meets the condition of the specified data volume. For example: the specified data volume condition is 50kb, when the data volume corresponding to each URL in the response information is greater than or equal to 50kb, the preloading operation can be carried out, and when the data volume corresponding to a certain URL is less than 50kb, the preloading operation can not be carried out on the video corresponding to the URL.
In one embodiment, when the URL is included in the response information, the foregoing step 402 may be implemented to perform, for each video: and completing the preloading operation of the corresponding preloading data content based on the URL of the preloading data content of each video.
The following modes can be implemented:
mode A: and performing preloading operation on the preloading data content of each video in the user browsing page, and ending the preloading operation on the video if the data volume of the received video reaches the data volume of the preloading data content of the video.
Wherein, the ending of the preloading operation can be implemented in the following ways:
1. disconnecting the connection and ending the preloading operation of the video.
2. The server sends response information to the client, the server sends each video preloading data content, and the client receives the preloading data content. If the client does not receive the preloaded data content successfully and waits for a certain period of time without receiving the preloaded data content of the video in the process, the client can resend the request to the server so as to continue preloading of the video. In implementation, the client and the server can complete preloading of the video based on breakpoint resuming.

By dividing the client into two functional services, the functions of the service layer and the preloading module can be separated at the client, so that the preloading module is only used for loading, and the service layer only processes service logic, for example, filters out a part of video information which is not required to be loaded. The client can conveniently maintain the functions of the service logic and the preloading module of the service layer respectively. When implemented, the method can comprise the following steps:
step 501: the client sends an acquisition request of the video page to the service server.
Step 502: and the service server determines the preloaded data content of each video in the video page according to the preset preloaded time and the video related information.
Step 503: and the service server indicates the client to finish the preloading operation of each video according to the determined preloading data content of each video in the video page.
Step 504: the client determines the videos needing to be loaded according to the service requirements, and sends video acquisition requests to the video server according to the URLs of the videos needing to be loaded.
Step 505: and the client receives the video URL returned by the video server, and does not need to filter if the service server filters the video URL, or performs filtering operation if the service server does not filter the video URL.
Step 506: and the client finishes the preloading operation according to the video URL and the corresponding preloading data content.
