How to use the video recording function in uniapp

Today, the author will introduce to you how to use the video recording function in the uniapp development framework. uniapp is a cross-platform development framework. We can run our applications on multiple platforms at the same time based on the code written once, which is very convenient for developers. In uniapp, we can use the uni-AD-IN camera component to implement the video recording function.

First, we need to install the uni-AD-IN camera component in the uniapp project. This component can be installed in the project through the following command:

npm install @dcloudio/uni-ad-in --save

After the installation is completed, we need to introduce the component in the App.vue file. Add the following code in the script tag:

import '@dcloudio/uni-ad-in'

Next, we need to use the component in the page. Add the following code to the template tag in the page where video recording needs to be displayed:

<ad-in v-bind:cameraStreaming="true" v-on:cameraState="onCameraState"></ad-in>

In the script tag, we need to define a data attribute and define the onCameraState method to monitor changes in the video recording state. The code is as follows:

data() {
  return {
    cameraState: ''
  }
},
methods: {
  onCameraState(e) {
    this.cameraState = e.detail
  }
}

With the above code, we can already display the video recording function on the page. In order to better control and display the video recording process, we can also add buttons to trigger recording and stop recording operations. Add the following code in the template tag:

<button @click="startRecording">开始录制</button>
<button @click="stopRecording">停止录制</button>

In the script tag, we need to define the startRecording and stopRecording methods to trigger the recording and stop recording operations respectively. The code is as follows:

methods: {
  startRecording() {
    this.$refs.adIn.startRecording()
  },
  stopRecording() {
    this.$refs.adIn.stopRecording()
  }
}

With the above code, we can already implement the video recording function. When we click the start recording button, the video will start recording, and the recording status will be prompted by changing the cameraState property. When we click the stop recording button, the recording will stop and the recorded video can be processed through other logic.

To summarize, using the video recording function in uniapp mainly involves the following steps: install the uni-AD-IN camera component, introduce the component and use it in the page, define data attributes and monitoring methods to control the recording status Changes to add buttons to trigger recording and stop recording operations. Of course, in actual development, we can also customize the recording process more as needed.
