How to implement short video and live broadcast functions in uniapp

With the development of the mobile Internet, short videos and live broadcasts have become a hot trend in the field of social entertainment. Implementing short video and live broadcast functions in uniapp allows developers to create more engaging and interactive applications. This article will introduce how to implement short video and live broadcast functions in uniapp, and provide specific code examples.

1. Implementation of short video functions
   Short video functions mainly include video recording, editing and sharing. The following are the steps and sample code to implement the short video function in uniapp:

1.1 Use the recording and camera API provided by uniapp to obtain audio and video data.

// 开始录制视频
wx.startRecord({
  success: function(res) {
    var tempVideoPath = res.tempFilePath;
    // 保存视频文件路径，用于后续编辑和分享
  },
  fail: function(res) {
    // 录制失败的处理逻辑
  }
});

1.2 Use the video editing function provided by uniapp to crop the recorded video, add filters, etc.

// 裁剪视频
uni.chooseVideo({
  success: function(res) {
    var tempVideoPath = res.tempFilePath;
    // 对视频进行裁剪处理
  },
  fail: function(res) {
    // 选择视频失败的处理逻辑
  }
});

1.3 Use the social sharing API provided by uniapp to share the edited video to Moments or other social platforms.

// 分享视频
uni.share({
  title: '分享',
  path: '/pages/video',
  success: function() {
    // 分享成功的处理逻辑
  },
  fail: function() {
    // 分享失败的处理逻辑
  }
});

2. Implementation of live broadcast function
   The live broadcast function mainly includes video collection, streaming and playback. The following are the steps and sample code to implement the live broadcast function in uniapp:

2.1 Use the camera API provided by uniapp to obtain the video data collected by the camera.

// 获取摄像头数据
wx.createCameraContext().startRecord({
  success: function(res) {
    var tempVideoPath = res.tempVideoPath;
    // 对摄像头数据进行处理
  },
  fail: function(res) {
    // 获取摄像头数据失败的处理逻辑
  }
});

2.2 Use the push API provided by uniapp to push the collected video data to the live broadcast server.

// 推流
wx.createLivePusherContext().start({
  success: function() {
    // 推流成功的处理逻辑
  },
  fail: function() {
    // 推流失败的处理逻辑
  }
});

2.3 Use the video playback API provided by uniapp to play the video stream returned by the live broadcast server.

// 播放直播视频
uni.createLivePlayerContext().play({
  success: function() {
    // 播放成功的处理逻辑
  },
  fail: function() {
    // 播放失败的处理逻辑
  }
});

The above are the specific steps and sample code to implement short video and live broadcast functions in uniapp. Developers can improve and extend it according to their needs to create more interesting and creative applications. I wish you all success in the development process!
