An embodiment of a method for downloading a video resource according to the present application is described below, and fig. 2 is a flowchart illustrating a method for downloading a video resource according to an embodiment of the present application, where the present specification provides the method operation steps described in the embodiment or the flowchart, but may include more or less operation steps based on conventional or non-creative labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. In practice, the system or server product may be implemented in a sequential or parallel manner (e.g., parallel processor or multi-threaded environment) according to the embodiments or methods shown in the figures.
Referring to fig. 2, a method for downloading a video resource is shown, which can be applied to a server side, and the method includes:
s210, responding to a click instruction, acquiring video resources of a video to be downloaded, wherein the video resources are video resources applied to the media source expansion playing mode for playing;
further, referring to fig. 3, before the step of acquiring the video resource of the video to be downloaded in response to the click instruction, the method further includes:
s310, responding to a click instruction, and acquiring network identification information of a network page, wherein the network page is positioned by network resources with videos to be downloaded;
s320, acquiring network resource positioning of the video to be downloaded according to the network identification information;
s330, replacing the network resource to be positioned as the video resource of the video to be downloaded.
Specifically, the website that the user clicks to enter is a website for Media Source Extensions (MSE) that supports video playing. The MSE may replace the location of a typical single media file pointing to an external resource (source, src) with a reference to a mediaresource object (MediaSource), where the content pointed to by src will be applied to the location of the current tag in the document, so that the video content can be played directly. MSE can also reference multiple video binary data storage objects (SourceBuffer), which can control playback more precisely and can protect source data.
The fifth version of hypertext Markup Language (HTML 5) can be extended by MSE to describe the playback format supported by the page. Allowing JavaScript to generate media streams to support playback can be used in application scenarios such as adaptive streaming and live video streaming over time.
S220, acquiring video stream data according to the video resource of the video to be downloaded, and storing the video stream data into a resource cache region;
further, referring to fig. 4, the video stream data includes: the method comprises the steps of carrying out sound-picture synchronization synthesis in a later period according to picture fragment data and audio fragment data, wherein the picture fragment data only has pictures without sound, and the audio fragment data only has sounds without pictures; the resource buffer area comprises a picture resource buffer area and an audio resource buffer area, the resource media type set in the picture resource buffer area can be video/mp4, and the resource media type set in the audio resource buffer area can be audio/mp 4;
the acquiring video stream data according to the video resource of the video to be downloaded and storing the video stream data in a resource buffer area comprises:
s410, acquiring picture data in the video resource;
s420, acquiring audio data in the video resource;
s430, segmenting the picture data to obtain picture fragment data;
s440, segmenting the audio data to obtain audio segment data;
s450, creating a picture resource cache region, and storing the picture fragment data into the picture resource cache region;
and S460, creating an audio resource buffer area, and storing the picture fragment data into the audio resource buffer area.
Specifically, the video stream data can be obtained by performing a page playing process and analyzing the video resources. The video website played by applying the MSE mode can be a live broadcast website or an on-demand website, and protocol analysis and data encapsulation analysis are performed to obtain audio data and picture data, and finally the audio data and the picture data are played after the audio data and the picture data are synchronized.
In the process of playing a page, there are three main events on the MediaSource object as a video resource, which are a start event (sourceopen), a close event (sourceclose), and a stop event (sourceended), respectively. Wherein the sourceopen event is triggered after the video resource is obtained. The sourceended event is triggered when the user actively calls termination or video data parsing, playing error. The sourceclose event is triggered when there is no data available in SourceBuffer and the HTML support underlying media related capabilities component (HTMLMediaElement). After the video resource is acquired, the sourceopen event is monitored to ensure that the MediaSource and HTMLMediaElement have completed binding, and entry into the data processing flow begins only after that.
In the process of data processing, as the resource media type of the resource cache region can only be one type, in the process of page playing, the video resource to be downloaded is divided into picture data and audio data.
In some specific examples, the resource cache may be a SourceBuffer. The SourceBuffer is a container storing video stream data to be transferred into HTMLMediaElement via MediaSource objects, such as audio play tags (audio) and video play tags (video) in HTML. The browser starts an audio tag and a video tag, the browser simultaneously starts a page player capable of playing in an MSE mode, and after video stream data is converted into binary cache data, the page player can receive the binary cache data and play video resources.
When the SourceBuffer is used as the resource cache area, one SourceBuffer object can only accept data in one format, so that a SourceBuffer needs to be created for video and audio data respectively. For example, if the media type of the resource cached in the resource cache is fixed to the type associated with the picture data, such as video/mp4, then the picture data can only be added to the resource cache. The resource media type of the resource buffer is fixed to the audio data related type, for example, audio/mp4, and then only audio data can be added to the resource buffer. Finally, the video resource can be divided into picture data and audio data, and two resource buffer areas are set for respectively caching the picture data and the audio data.
The video website realized by the MSE playing mode can analyze video stream data, can support the playing of video media with more formats, and can also be applied to scenes for playing videos by live broadcasting or on demand.
S230, converting the video stream data in the resource cache region into playing cache data;
s240, responding to a downloading instruction, establishing a background simulation playing process, and transmitting the playing cache data to a downloading actuator through the background simulation playing process;
further, referring to fig. 5, fig. 5 shows a method for creating a background simulation playing process and transmitting data to a download executor through the background simulation playing process, where the method includes:
s510, setting the background simulation playing process to be in a mute mode;
s520, in a mute mode, based on the simulation operation of the playing event, transmitting the playing cache data to a downloading executor.
Specifically, the MSE can extend the video format that the web page described by the HTML5 can play, but does not support video downloading, so the method described in this embodiment adopts a way of creating an analog playing process in the background. The playing cache data is acquired by a mode of analog playing and is transmitted to the downloading actuator for downloading the video, and because the page playing process can be simultaneously carried out on the page, the background analog playing process needs to be set to be in a mute mode, so that the interference to the page playing process can be avoided.
In some specific examples, referring to fig. 6, the method for setting the background analog playing process to be in the mute mode includes:
s610, acquiring audio attributes of video resources played in the background simulation playing process;
s620, converting the audio attribute into an audio numerical value;
and S630, setting the background simulation playing process to be in a mute mode based on the adjustment of the audio numerical value.
In a specific example, when the audio value is adjusted, the audio value is adjusted to a minimum value or to 0, and then the background analog playing process may be set to the silent mode.
And responding to the input downloading instruction, starting a background simulation player by the background to perform simulation playing, wherein the background simulation player is a simulation player applied to media source expansion playing, can request a resource cache region to play cache data, and can decode audio and video and perform rendering.
Referring to fig. 7, fig. 7 shows a method for transmitting the play cache data to a download executor based on a simulation operation of a play event in a mute mode, the method comprising:
s710, starting a background simulation player, wherein the background simulation player is a simulation player applied to media source expansion playing;
s720, requesting the play cache data from the resource cache region to the background simulation player for playing;
and S730, transmitting the play cache data played in the background simulation player to a download executor.
In some specific examples, the playing buffer is SourceBuffer, the SourceBuffer in which the video stream data is stored is transmitted to a browser kernel through a JavaScript programming script, and the browser kernel converts the video stream data in the SourceBuffer into binary buffer data and transmits the binary buffer data to a background analog player for analog playing. And the binary cache data are sequentially transmitted to a background simulation player for playing according to the sequence of time stamps and the like, so that complete video resource information is formed. The background simulation player consumes the binary cache data in a simulation playing mode and transmits the binary cache data to the download executor. The download executor may be a multimedia file downloader providing download capabilities for various video formats. The downloading executor can directly download and play the cache data and output the video file which is downloaded successfully. And performing additional storage and renaming operation on the successfully downloaded video file, and storing the video file locally.
In a specific embodiment, during play simulation, the browser loads and analyzes a video tag and then loads a background simulation player, the background simulation player triggers a play event and a seek event to enable a page to continuously playback cache data, the background simulation player distributes the playback cache data to a download executor, the seek event is continuously triggered, and finally all the playback cache data are acquired.
The method is easy to execute, has good practicability and universality, and can be applied to video websites supported by all media source extensions.
And S250, downloading the play cache data from the download executor.
Referring to fig. 8, fig. 8 shows a flowchart when a page playing process and a background playing process exist simultaneously. A user starts a browser to enter a website which is played by applying an MSE mode, and a browser kernel analyzes, loads and renders a webpage. After the page is loaded and rendered, the browser starts a page player, the audio and the video are decoded and rendered, and a user watches the video through the page player. When a user needs to download, clicking a download button, starting another browser kernel by the background, analyzing the video resource and obtaining video stream data by the browser kernel, and storing the video stream data in a play cache region. And converting the video stream data into play cache data, wherein the play cache data can be binary cache data. And the background enters a simulation playing process and starts the background simulation player. Setting the background simulation player to be in a mute mode, requesting to play the cache data to the background simulation player for simulation play, and transmitting the play cache data to the download actuator. And downloading can be carried out from the downloading executor, and finally, the video file which is successfully downloaded is output.
In a specific example, in a live broadcast scene in which the MSE technology is applied more, a user may start a background analog player to download a video in the live broadcast process, so that the user may view the video and download the video in the background at the same time. And when the user needs to download, the background responds to a download instruction, establishes a background simulation player, requests for playing cache data in the resource cache region, and transmits the playing cache data to the download actuator for downloading.
The embodiment of the invention provides a method for downloading video resources, which comprises the steps of analyzing the video resources to be downloaded, obtaining video stream data, converting the video stream data into play cache data, and storing the play cache data into a resource cache region. The method comprises the steps of creating a background simulation playing process executed by a background simulation player in addition to a page playing process executed by a page player, requesting playing cache data in a resource cache region based on simulation operation of a playing event, transmitting the playing cache data to a download actuator, obtaining related data in a video applied to an MSE playing mode, and downloading data from the download actuator. Further, the beneficial effects include:
(1) the MSE video resource downloading is supported, the webpage range of video downloading is expanded, webpage video downloading with more formats can be performed, the user experience is improved, and the user viscosity is increased;
