Detailed Description
Embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
In a first aspect, the present invention provides a video capture method for a terminal device. Referring to fig. 1, fig. 1 is a flowchart illustrating main steps of a video capture method for a terminal device according to the present application. As shown in fig. 1, the video capture method for a terminal device of the present invention includes the following steps:
s1, when a video recording request is received, the webpage calls a video acquisition SDK from the server;
s2, judging whether the browser supports video recording or not by using the video acquisition SDK;
and S3, according to the judgment result, the video acquisition SDK selectively requests the permission of a camera and a microphone of the browser to record the video, or opens a native camera of the terminal equipment to record the video.
Fig. 2 is a flowchart illustrating the detailed steps of the video capture method for a terminal device according to the present invention. The video capture method for the terminal device according to the present invention is described in detail below with reference to fig. 2.
The video acquisition method for the terminal equipment specifically comprises the following steps:
and step S1, when a video recording request is received, the webpage calls a video acquisition SDK from the server.
Specifically, when a user uses a browser of a terminal device to perform video capture, a video capture SDK is first invoked.
As a preferred example, the video capture SDK used by the present invention is cwmedia collector.
In actual operation, before calling the video capture SDK from the server, the web page needs to create an SDK instance in advance and set configuration parameters. The method specifically comprises the following operations:
1. js in the browser page.
<script src＝"./CWMediaCollector.js"></script>
2. Setting a video preview component, and adding a video element in a div, wherein the video element contains autoplay and playinline attributes;
<div class＝"video"id＝"video-box">
<video class＝"video"id＝"video"autoplay playsinline></video>
</div>
3. the cwmedia collector object is initialized and relevant parameters are set.
And step S2, judging whether the browser supports video recording or not by using the video acquisition SDK.
Specifically, the video capture SDK first determines whether the browser supports the API getUserMedia ().
If the browser supports API getUserMedia (), it is indicated that the video acquisition SDK can acquire the camera and microphone rights of the device through the browser. That is to say, the video capture SDK already has a video capture capability, and since the browser does not have general compatibility, it needs to further determine whether the browser supports video recording according to the situation of the browser version. In step S3, how to determine whether the browser supports video recording according to the browser version will be described in detail.
If the browser does not support API getUserMedia (), judging that the browser cannot acquire the camera and microphone rights of the equipment, namely the browser does not support video recording. At this time, the video capture SDK automatically requests entry into the device native camera to record the video.
Before the video acquisition SDK automatically requests to enter the native camera of the device for recording the video, the video acquisition SDK firstly judges the condition of the current browser parameter setting. And if the current browser is set to be in the compatibility priority mode, directly calling the native camera to carry out video acquisition by the video acquisition SDK.
If the current setting of the browser is not the compatibility priority mode, the user is more concerned about the browsing experience, namely the user does not want to jump to other application interfaces when using the browser. At the moment, the video acquisition SDK does not call the native camera to acquire the video, but informs the user that the current browser setting does not support video recording in a prompting message mode, and reminds the user to modify the setting parameters of the related browser, so that the browser with the modified parameters can meet the requirement that the video acquisition SDK calls the native camera to acquire the video.
And step S3, according to the judgment result, the video acquisition SDK selectively requests the permission of a camera and a microphone of the browser to record the video, or opens a native camera of the terminal equipment to record the video.
Specifically, if the video acquisition SDK can obtain the permission of the camera and the microphone of the browser, the method continues to determine and select a suitable video recording mode according to the system version of the terminal device and the version of the current browser. The specific process is as follows:
and the video acquisition SDK judges whether the operating system used by the terminal equipment is an iOS system or an android system.
And if the operating system used by the terminal equipment is the iOS system, continuously judging whether the current browser version is 14.1 or more. If yes, the browser can record the video by calling the camera and microphone rights of the equipment and using the API mediastreamRecorder. If not, the video is recorded using the native camera.
And if the operating system used by the terminal equipment is the android system, continuously judging whether the current browser version is version 9 or more. If so, the video can be recorded by calling the camera and microphone rights of the device and using the API webassblyRecorder. If not, the video is recorded using the native camera.
In addition, when the video acquisition SDK records a video through a browser of the terminal equipment, the specific steps are as follows:
firstly, a video acquisition SDK utilizes API getUserMedia () to open a camera of a terminal device to acquire media data media, including video and audio;
recording media data by using an API media recorder or an API webassblyrecorder, and converting a recorded media data stream into a video data file in a universal WEBM/MP4 format;
and then converting the recorded WEBM/MP4 file into a BLOB data format and sending the BLOB data format to a browser page so that the browser can exchange data with a server.
When the video acquisition SDK records a video through a native camera of the terminal device, the specific steps are as follows:
firstly, creating an < input/> tag in sdk in an invisible mode (a main page is invisible), configuring a file format to be video, and capturing and acquiring a video file through a camera;
then, simulating and triggering an < input/> tag click event, entering a native camera, and controlling to record a video by the terminal equipment;
and finally, after the video recording is finished, < input/> acquiring the recorded MP4 video file, converting the MP4 video file into a BLOB data format and sending the BLOB data format to a browser page so as to enable the browser to exchange data with the server.
The video acquisition method for the terminal equipment can meet the requirements of light-weight and convenient video acquisition by adopting different operating system terminal equipment and browsers of different versions. The invention can realize video acquisition without installing any client software, and reduces the software and hardware loads of the terminal equipment, thereby realizing the aim of lightweight video acquisition. According to the invention, a suitable video acquisition mode can be automatically selected for video acquisition according to the specific setting condition of the terminal equipment, so that the operation of a user is facilitated.
The video capture apparatus for a terminal device of the present invention is described below with reference to fig. 3. As shown in fig. 3, the apparatus includes: the calling module is used for calling the video acquisition SDK from the server through the webpage when receiving a video recording request; the judging module is used for judging whether the browser supports video recording or not by utilizing the video acquisition SDK; and the control module controls the video acquisition SDK to selectively request the permission of a camera and a microphone of a browser to record videos or open a native camera of the terminal equipment to record videos according to the judgment result of the judgment module.
Preferably, if the video acquisition SDK determines that the browser supports video recording, the control module controls the video acquisition SDK to further determine whether the browser version meets the video recording requirement of the web page; and if so, controlling the video acquisition SDK to call the camera and the microphone authority of the browser to record the video.
