Notes

Using the live-player component has category restrictions. You need to pass the category review first. 1536218165(1) Then, in the mini program management backend, go to "Settings" - "Interface Settings" to self-service enable the component permissions. 1536218076(1)

The SDK uses the live-player component by default and uses the flv stream URL.

setPlayerSrc(videoInfo) {
    this.setData({
      video: {
        src: videoInfo.flvSrc, // videoInfo.flvSrc返回flv地址
        poster: videoInfo.poster
      }
    });
  }

If the mini program component used is video, you need to set the playback URL to m3u8.

<view class="video-wrap">
    <view class="video-box">
        <video id="polyvLiveVideo" class="vp-v" src="{{video.src}}" controls autoplay></video>
    </view>
</view>

setPlayerSrc(videoInfo) {
    this.setData({
      video: {
        src: videoInfo.src, // videoInfo.src返回m3u8地址
        poster: videoInfo.poster
      }
    });
  }
