Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is a diagram of an application environment of a video loading method in one embodiment. Referring to fig. 1, the video loading method is applied to a video loading system. The video loading system includes a terminal 110 and a cloud server 120. The terminal 110 and the cloud server 120 are connected via a network. The terminal 110 downloads video data from the cloud server 120, and acquires a video playing position when playing a video; determining a video time period of a video to be loaded according to the video playing position and a preset time length to be loaded; when at least a part of the video data in the video period is not loaded in the video buffer container, downloading at least a part of the video data from the cloud server 120; and loading at least part of the downloaded video data into a video buffer container.
The terminal 110 may be a desktop terminal or a mobile terminal, and the mobile terminal may be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. The cloud server 120 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers.
Cloud storage (cloud storage) is a new concept extended and developed from a cloud computing concept, and a distributed cloud storage system (hereinafter, referred to as a storage system) refers to a storage system which integrates a large number of cloud servers 120 of different types in a network through application software or application interfaces to cooperatively work through functions such as cluster application, a grid technology, a distributed storage file system and the like, and provides data storage and service access functions to the outside.
At present, a storage method of a storage system is as follows: logical volumes are created, and when created, each logical volume is allocated physical storage space, which may be the disk composition of a certain storage device or of several storage devices. The client stores data on a certain logical volume, that is, the data is stored on a file system, the file system divides the data into a plurality of parts, each part is an object, the object not only contains the data but also contains additional information such as data identification (ID, ID entry), the file system writes each object into a physical storage space of the logical volume, and the file system records storage location information of each object, so that when the client requests to access the data, the file system can allow the client to access the data according to the storage location information of each object.
The process of allocating physical storage space for the logical volume by the storage system specifically includes: physical storage space is divided in advance into stripes according to a group of capacity measures of objects stored in a logical volume (the measures often have a large margin with respect to the capacity of the actual objects to be stored) and Redundant Array of Independent Disks (RAID), and one logical volume can be understood as one stripe, thereby allocating physical storage space to the logical volume.
In one embodiment, as shown in FIG. 2, a video loading method is provided. The embodiment is mainly illustrated by applying the method to the terminal 110 in fig. 1. Referring to fig. 2, the video loading method specifically includes the following steps:
s202, when the video is played, the video playing position is obtained.
In one embodiment, the terminal plays a video through a webpage, and in the process of playing the video, the video playing position is obtained. The video playing position may be a position played according to a normal playing sequence, or a playing position jumped to according to an input control instruction, so as to load video data after the video playing position.
The web page may be a web page constructed by HTML (Hyper Text Markup Language) version 5, that is, HTML5, or a web page constructed by a subsequent version of HTML 5. The web page may be a stand-alone browser, such as a computer-based browser, a cell phone-based browser, a tablet computer-based browser, and the like. In addition, the web page may also be a web page embedded in an application program, such as a browser embedded in a social application.
For example, assuming that the total duration of a video is 3 minutes and 4 seconds, playing the video through a web page, and when playing to the point a according to the normal playing sequence, acquiring the time corresponding to playing to the point a, where the time is the current video playing position. And when jumping to the point A according to a control instruction input by a user, acquiring the time corresponding to the time when the video is played to the point A, wherein the time is the current video playing position.
Taking HTML5 web page as an example, a video tag, attributes corresponding to the video tag, and an API (Application Programming Interface) are newly added to HTML 5. The video tags define videos, such as movie clips or other video streams. The corresponding video can be played in the webpage through the video tag. Attributes and APIs in the video tag can be referred to as table 1 and table 2 below, respectively.
TABLE 1 Properties of video tags
| Properties | Value of | Description of functions |
| controls (control) | controls | Whether to display playing control |

Wherein, if the Autobuffer is not set, the Autoply is valid.
The API provided in the Video tag can be directly called by the JS, and the API is as follows:
TABLE 2 API for video tags
For example, the video tags are: < video src = "xxx. Mp4" controls = "controls" >, the src attribute functions to set a URL (Uniform Resource Locator) address of a video to be played, and the control attribute functions to indicate whether a play control is displayed.
In one embodiment, when the video starts to be played, the terminal loads the native player through the webpage, plays the video through the native player, and acquires the video playing position in real time in the process of playing the video.
The native player can be a native player carried by the system or an installed third-party native player. Native players, which may also be referred to as Native players, use system Native code generated players. For example, for the android system, the native player may be a player generated using android system native JAVA code.
In one embodiment, before S202, the terminal performs data interaction with a cloud server (hereinafter, referred to as a server) through an XHR (XMLHttpRequest) object of the web page, so that video data can be downloaded from the server.
And S204, determining the video time period of the video to be loaded according to the video playing position and the preset time length to be loaded.
The preset duration to be loaded may refer to: when loading video data, the length of time required to load the video. The preset loading duration may be a default step length of the system, may be automatically set by the system according to the network speed, or may be a step length set by the user according to the actual demand. For example, when the user's demand is to load a video within n seconds in the future, the preset time duration to be loaded is n, for example, n =16.
A video period may be a time period between a start position (i.e., a start time) and an end position (i.e., an end time) of a certain video segment in a video, the time period including the start position and the end position. For example, as shown in fig. 3, the video period may be a period from point a to point B, i.e., a period from 20 th to 36 th seconds of the video. The point a is a node with a playing time of 20 seconds, and the point B is a node with a playing time of 36 seconds.
In one embodiment, the terminal detects the network speed, and determines the preset duration to be loaded according to the network speed, so as to determine the video time period of the video to be loaded according to the video playing position and the preset duration to be loaded. For example, as shown in fig. 3, assuming that the user only tries to watch the video and does not stay in the video for too long, when the user watches the video, if the network speed is high, the video may be downloaded in a short time, and the user leaves the web page only by watching a short segment of video, thereby causing waste of traffic, at this time, the terminal determines that only video data in the future 16 seconds need to be loaded according to the size of the traffic speed, and when playing to point a, the video data in the future 16 seconds can be loaded, that is, the video period to be loaded is the time period from point a to point B.
In one embodiment, S204 may specifically include: the terminal calculates the end position of video loading according to the video playing position and the preset time length to be loaded; and determining the video time interval to be loaded according to the video playing position and the ending position.
For example, as shown in fig. 3, when playing to the point a, assuming that the preset time duration to be loaded is 16, video data in the future 16 seconds may be loaded, and at this time, the terminal may determine, according to the time corresponding to the point a and the preset time duration to be loaded being 16, that the video period to be loaded is the time period from the point a to the point B, that is, the video period to be loaded is the time period from the 20 th second to the 36 th second.
S206, when at least one part of video data in the video time interval is not loaded in the video buffer container, downloading at least one part of video data from the server.
Wherein at least a portion of the video data may refer to: a portion of the video data within a video period, or all of the video data within a video period. A video Buffer container (Source Buffer Controller) may be a container for a user to Buffer video data, that is, after downloading video data from a server, the downloaded video data is loaded into the video Buffer container, or a packaging format of the downloaded video data is converted first, and then the converted video data is loaded into the video Buffer container.
In one embodiment, S206 may specifically include: when at least a part of Video data in the Video time interval is not loaded in the Video buffer container, the terminal acquires a Video link (such as a Video URL address) in the Video tag, and downloads at least a part of corresponding Video data from a server corresponding to the Video link according to the Video time interval.
For example, assume that the video tag is:
<video controls>
< source src = "www.xxx/hand angee.mp4" type = "video/mp4" >/the URL address of video is www.xxx/hand. Mp4
</video>
Then, the terminal will link to the corresponding server according to www.xxx/hand.mp 4, and then download the corresponding video data according to the time period from point a to point B, and if the video buffer container has loaded part of the video data in the time period from point a to point B, the terminal needs to download another part of the video data in the time period from point a to point B. If the video buffer container does not load the video data in the time period from point a to point B, the terminal needs to download all the video data in the time period from point a to point B.
Specifically, the method comprises the following steps: and when a part of Video data in the Video time interval is not loaded in the Video buffer container, the terminal acquires the Video link in the Video tag, and downloads the corresponding part of Video data from a server corresponding to the Video link according to the Video time interval. And when all the Video data in the Video time interval are not loaded in the Video buffer container, the terminal acquires the Video link in the Video tag, and downloads all the Video data in the Video time interval from a server corresponding to the Video link according to the Video time interval.
In one embodiment, the downloaded video data may be downloaded through a download controller. Specifically, the terminal judges whether at least a part of video data in a video time interval is loaded in the video buffer container through the scheduling logic controller, and if not, the terminal sends a control instruction to the download controller so that the download controller downloads at least a part of video data which is not loaded in the video buffer container from the server. Wherein, the scheduling logic Controller is MSE Controller.
And S208, loading at least a part of the downloaded video data to a video buffer container.
In an embodiment, S208 may specifically include: when the downloading is finished, the terminal converts the packaging format of at least one part of the downloaded video data; and loading at least a part of video data obtained by conversion into a video buffer container.
Among them, the package format may refer to a Video format, for example, an avi (Audio Video Interleaved) package format, an mkv (Multimedia Container) package format, an rmvb (real media Variable bit rate) package format, an mp4 (Moving Picture Experts Group 4) package format, and the like.
In one embodiment, when at least a part of video data which is not loaded in the video buffer container is completely downloaded through the download controller, the terminal notifies the trans-encapsulation controller through the download controller in a callback function manner, so that the trans-encapsulation controller performs trans-encapsulation processing on the downloaded at least a part of video data, that is, converts the encapsulation format of the at least a part of video data, and then loads the at least a part of video data obtained through conversion into the video buffer container.
For example, the decapsulation controller decapsulates the downloaded mp4 encapsulated format video data to obtain an fmp4 encapsulated format, and then adds the fmp4 encapsulated format video data to the video buffer container. In an mp4 file, the metadata of the mp4 file is in the header, all the media data are in one block, and in order to avoid the buffer time from being prolonged due to the storage structure of the mp4 file, at this time, the large mp4 file is cut into multiple segments which are physically separated, so that meta of each segment is relatively small, and video data in an fmp4 packaging format is obtained.
In the above embodiment, the current video playing position is obtained in time, the video time period of the video to be loaded is determined according to the video playing position and the preset time length to be loaded, and the corresponding video data is downloaded according to the video time period of the video to be loaded, so that the video to be played in the future can be effectively preloaded, and the problem of blocking during playing is avoided. In addition, before downloading the video data, whether the video data in the video time interval is loaded in the video buffer container is judged, if at least one part of the video data is not loaded in the video buffer container, at least one part of the video data which is not loaded in the video buffer container is downloaded, and then the video data is loaded in the video buffer container, so that the problem of repeated loading of the video data is solved. Moreover, the video playing position and the preset time length to be loaded determine the video time period of the video to be loaded, so that the network speed is not required to be limited, the video data in the video time period can be loaded in a short time, the waste of data flow is avoided, and the video loading efficiency is effectively ensured.
Finally, the video playing position can be set, when loading, the corresponding video data can be loaded according to the set video playing position and the preset time length to be loaded, the mode of loading the video data is flexible, the scheduling loading of the video data is realized, and the problem of blocking during playing is avoided.
In one embodiment, as shown in fig. 4, after S208, the method may further include:
s402, video data are obtained from the video buffer container according to the video playing position.
The video buffer container may be a container for caching video data by a user, that is, after downloading video data from a server, the downloaded video data is loaded into the video buffer container, or a packaging format of the downloaded video data is converted first, and then the converted video data is loaded into the video buffer container.
In one embodiment, the terminal may acquire all video data located after the video playing position from the video buffer container, or acquire a part of video data located after the video playing position from the video buffer container, and then perform S404.
In one embodiment, the terminal determines the length of the video to be decoded at each decoding according to the local calculation performance, acquires a portion of video data located after the video playing position in the video buffer container according to the determined video length, and then performs S404. The computing performance includes, but is not limited to, utilization of a processor, remaining memory space, and the like.
For example, as shown in fig. 3, if all the video data after the video playing position are acquired (assuming that the duration of all the video data after the video playing position is 16 seconds), when the video is played for the 20 th second, the video data in the 20 th to 36 th seconds of the video are acquired from the video buffer container. When the video is played for the 20 th second and the length of the video decoded each time is determined to be 5 seconds according to the self calculation performance of the terminal, the terminal acquires the video data in the 20 th to 25 th seconds from the video buffer container.
In one embodiment, after S208 and before S402, the method further comprises: the terminal generates a response event about the completion of the loading of at least a part of the video data; the response event is sent to the dispatch logic controller. In an embodiment, S404 may specifically include: and when the scheduling logic controller determines that at least one part of the video data is completely loaded according to the response event, the scheduling logic controller acquires the video data which is loaded in the video buffer container and belongs to the video time interval according to the video playing position.
For example, assuming that the current video playing position is 20 th second, the video data of 20 th to 30 th seconds are already loaded, and the video data of 20 th to 36 th seconds are needed to be loaded in total, at this time, the terminal downloads the video data of 30 th to 36 th seconds through the download controller, and then loads the video data into the video buffer container, at this time, the video buffer container will notify the video buffer container in a manner of responding to an event that the specified video data loading is completed, and the scheduling logic controller acquires the video data loaded in the video buffer container and belonging to the video period according to the video playing progress.

As an example, a video is played through a web page, and due to the scheme that a video tag in the web page is associated with video data through an src attribute, video can not be scheduled, loaded, processed, and controlled, and thus video data can not be preloaded, which causes problems of pause in playing, long time consumed in playing a first frame image of the video, and the like. In this embodiment, a video loading method is provided, which may solve the above technical problem, and as shown in fig. 7, the specific method steps may include:
(1) A scheduling logic Controller (MSE Controller) is used as a core of service playing scheduling, and firstly a video Buffer container (Source Buffer Controller) is set through an initialization interface, and the Source Buffer Controller can be used for storing and managing video data to be played.
(2) The MSE Controller judges whether the video data cached in the Source buffer meets normal decoding playing or not according to the current demand for the buffered video (the demand can be video data within n seconds in the future after the current playing time is loaded, and n is a positive number which is more than 1 and less than the total video time), if so, the MSE Controller does not load new video data, and if not, a control instruction for loading the new video data is sent to the download Controller.
(3) And after receiving the control instruction of the MSE Controller, the download Controller downloads the mp4 video data according to the demand. For example, mp4 video data specifying the chunk size is downloaded in a byte-range manner.
(4) And the download controller acquires the specified mp4 video data after the loading is finished, and then notifies the trans-encapsulation controller in a callback function mode so that the trans-encapsulation controller finishes trans-encapsulation processing on the loaded mp4 video data.
(5) And the trans-encapsulation Controller carries out trans-encapsulation processing on the mp4 video data to obtain fmp4 video data, and then adds the fmp4 video data into a Source Buffer Controller for standby.
(6) After receiving the fmp4 video data and successfully storing the fmp4 video data into the standby Buffer, the Source Buffer Controller informs the MSE Controller of completing loading the fmp4 video data of the specified segment with the specified size through a response event.
(7) And dynamically deciding whether the fmp4 video data cached in the Source Buffer Controller meets the playing requirements of side-by-side playing, flow optimization and pause optimization or not by the MSE Controller processor according to the video playing progress, and bridging the fmp4 video data to the video module for decoding and playing if the fmp4 video data meets the playing requirements of side-by-side playing, flow optimization and pause optimization. If not, the above steps (2) to (5) are continuously executed in a loop until the fmp4 video data capable of meeting the playing requirement is loaded.
By adopting the scheme of the embodiment, the amount of the video data to be loaded can be determined according to the playing requirement of the current playing time point, for example, the amount of the video data to be loaded can be set by a user, and the amount of the video data to be loaded can also be automatically adjusted according to the network speed.
As shown in fig. 3, point a in the graph is a node position corresponding to 20 seconds when the video is currently played, point B is a node position corresponding to the 36 seconds of the video that has been loaded, and point C indicates that the total duration of the video is 3 minutes 04 seconds. The time period required to load the video can be determined according to the currently played point A and the specified playing demand, the point B represents the time point when the video data is loaded, and when the video data is played to the 20 th second (point A) in the figure 3, the video data only loaded to the 20 th to 36 th seconds (point B) can be controlled.
By adopting the scheme of the embodiment, the required flow during video loading can be saved while the smoothness of the current video playing can be ensured, and the purposes of loading as required, optimizing the pause, reducing the abnormal playing and the like are achieved. In addition, since the video in the webpage is preloaded before playing, the time consumed for playing the first frame is effectively reduced, as shown in fig. 8, for an mp4 video with a duration of 20 seconds, the time consumed for the first frame is 1.4 seconds by using the scheme of the present embodiment, and the time consumed for the first frame is 2.6 seconds by using the conventional scheme.
