How to implement video recording and video playback functions in uniapp

With the rapid development of the mobile Internet, video plays an increasingly important role in people's lives . In uniapp development, implementing video recording and video playback functions is a common requirement. This article will introduce how to implement these two functions in uniapp and provide specific code examples.

1. Implementation of video recording function

To realize the video recording function, we can use the relevant plug-ins of uniapp and some HTML5 APIs. The specific steps are as follows:

1.1 Introduce relevant plug-ins

First, we need to introduce the video recording plug-in of uniapp, such as the "uni-media" plug-in. Add in the "usingComponents" node in the manifest.json file of the project:

"uni-media": "/static/uni-media/uni-media"

1.2 Create a video recording component

In the uniapp page, create a video recording component, such as VideoRecord.vue . Add the following code to the template:

<template>
  <view>
    <uni-media ref="media" @finish="onFinish"></uni-media>
    <button @click="startRecord">开始录制</button>
    <button @click="stopRecord">停止录制</button>
  </view>
</template>

1.3 Write recording logic

In the script of the VideoRecord.vue component, write the recording-related logic code. The specific sample code is as follows:

export default {
  methods: {
    startRecord() {
      this.$refs.media.startRecord({
        maxDuration: 60, // 录制时长限制，单位为秒
        cameraPosition: 'back', // 相机位置，back为后置摄像头，front为前置摄像头
      });
    },
    stopRecord() {
      this.$refs.media.stopRecord();
    },
    onFinish(res) {
      console.log(res.tempVideoPath); // 录制完成后的视频路径
    }
  }
}

So far, we have completed the implementation of the video recording function.

2. Implementation of video playback function

In uniapp, implementing the video playback function also requires the help of some plug-ins and APIs. The following are the specific steps:

2.1 Introduce related plug-ins

First, we need to introduce the video playback plug-in of uniapp, such as the "uni-media" plug-in. Add in the "usingComponents" node of the manifest.json file:

"uni-media": "/static/uni-media/uni-media"

2.2 Create a video playback component

In the uniapp page, create a video playback component, such as VideoPlayer.vue. Add the following code to the template:

<template>
  <view>
    <uni-media :src="videoSrc"></uni-media>
  </view>
</template>

2.3 Set the video source

In the script of the VideoPlayer.vue component, set the video source. The specific sample code is as follows:

export default {
  data() {
    return {
      videoSrc: '' // 视频源
    };
  },
  created() {
    this.videoSrc = 'http://example.com/video.mp4'; // 设置视频源，可以是本地或网络视频的地址
  }
}

At this point, we have completed the implementation of the video playback function.

Summary:
This article introduces how to implement video recording and video playback functions in uniapp. Through relevant plug-ins and API calls, we can easily implement these two functions and use them in mobile applications. I hope this article will be helpful to you in implementing video-related functions in uniapp development.
