Design and development methods of UniApp to implement video playback and live broadcast functions

UniApp is a cross-platform application development framework developed based on Vue.js. It can use a set of codes to build iOS, Android and Web applications at the same time. The video playback and live broadcast functions in UniApp can be achieved through the uni-app plug-in and the use of third-party SDKs. This article will introduce the design and development methods of UniApp to implement video playback and live broadcast functions, and provide code examples.

1. Design and preparation
Before starting development, we need to do some design and preparation work. First, determine the video playback and live broadcast SDK you need to use. Common video playback SDKs include Tencent Video Cloud SDK and Baidu Cloud Video Playback SDK, and common live broadcast SDKs include Tencent Cloud Live Broadcast SDK and Alibaba Cloud Live Broadcast SDK. Choose the appropriate SDK according to actual needs, and register an account to obtain the AppID and AppKey of the SDK.

Next, create the project and download the required uni-app plugin. You can search and download the corresponding plug-in in the plug-in market on the uni-app official website. Common video playback plug-ins are uni-video and uni-vedio, and common live broadcast plug-ins are uni-live-player and uni-live- pusher.

2. Implementation of video playback function

1. Introduction of video playback plug-in
   Introduce the required video playback plug-in into the pages.json file of the project, For example:

{
  "pages": [
    {
      "path": "pages/index/index",
      "style": {
        "navigationBarTitleText": "视频播放"
      }
    }
  ],
  "usingComponents": {
    "uni-vedio": "/static/uni-vedio/uni-vedio"
  }
}

2. Writing a video playback page
   Create the vedio folder in the pages directory, and then create index. vue file. Write the layout and interaction logic of the video playback page in index.vue. For example:

<template>
  <view>
    <uni-vedio :src="videoUrl"></uni-vedio>
  </view>
</template>
<script>
export default {
  data() {
    return {
      videoUrl: 'https://example.com/video.mp4'
    }
  }
}
</script>

define videoUrl in data to set the URL of the video. Then use the uni-vedio component in the template and bind videoUrl to the src attribute.

3. Implementation of live broadcast function

1. Introduction of live broadcast plug-in
   Introduce the required live broadcast plug-in into the pages.json file of the project, for example:

{
  "pages": [
    {
      "path": "pages/index/index",
      "style": {
        "navigationBarTitleText": "直播"
      }
    }
  ],
  "usingComponents": {
    "uni-live-player": "/static/uni-live-player/uni-live-player"
  }
}

2. Write live page
   Create the live folder in the pages directory, and then create index.vue document. Write the layout and interaction logic of the live broadcast page in index.vue. For example:

<template>
  <view>
    <uni-live-player :appId="appId" :appKey="appKey"></uni-live-player>
  </view>
</template>
<script>
export default {
  data() {
    return {
      appId: 'yourAppId',
      appKey: 'yourAppKey'
    }
  }
}
</script>

define appId and appKey in data and bind them to uni-live -On the properties of the player component.

4. Implement video playback and live broadcast functions
According to actual needs and SDK documentation, call the corresponding API to implement video playback and live broadcast functions. For example, the following is a code example for using Tencent Video Cloud SDK to implement video playback:

<template>
  <view>
    <video :src="videoUrl"></video>
  </view>
</template>
<script>
export default {
  data() {
    return {
      videoUrl: ''
    }
  },
  created() {
    // 调用腾讯视频云SDK的API获取视频地址
    this.getVideoUrl()
  },
  methods: {
    getVideoUrl() {
      // 调用接口获取视频地址
      // ...
      // 将视频地址赋值给videoUrl
      this.videoUrl = 'https://example.com/video.mp4'
    }
  }
}
</script>

Similarly, you can use the corresponding API to implement the live broadcast function according to the SDK documentation.

Summary
By using the uni-app plug-in and third-party SDK, the video playback and live broadcast functions in the UniApp application can be easily implemented. In the actual development process, you can choose the appropriate SDK and plug-in according to actual needs, and develop according to its documentation. This article provides design and development methods for video playback and live broadcast functions, as well as code examples, hoping to be helpful to UniApp developers.
