#鸿蒙通关秘籍#如何使用[@ohos.danmakuflamemaster]与[@ohos.gsyvideoplayer]集成视频弹幕功能？

在开发支持视频弹幕的播放器时，首先需要通过以下步骤进行设置：

1. 初始化播放器：

   videoInit: (iVideoPlayer: IVideoPlayer, xid: string) => void = (iVideoPlayer: IVideoPlayer, xid: string) => {
     this.mIVideoPlayer = iVideoPlayer;
     this.xComponentId = xid;
     this.mIVideoPlayer.setUp(this.videoModel.getUrl(), this.videoModel.getCacheWithPlay());
   }
   

2. 初始化弹幕：

   danmuInit() {
     let maxLinesPair: Map<number, number> = new Map();
     maxLinesPair.set(BaseDanmaku.TYPE_SCROLL_RL, 5); 
     let overlappingEnablePair: Map<number, boolean> = new Map();
     this.mContext = DanmakuContext.create();
     this.mContext.setDanmakuStyle(DANMAKU_STYLE_STROKEN, 3)
       .setDuplicateMergingEnabled(false);
     if (this.model != null) {
       this.mParser = this.createParser();
       this.model.setCallback(new Call(that));
       this.model.setOnDanmakuClickListener(new OnDanMu(that));
     }
   }
   

3. 添加弹幕示例代码：

   private addDanmaku(isLive: Boolean) {
     if (this.mContext) {
       let danmaku: BaseDanmaku = this.mContext.mDanmakuFactory.createDanmaku(BaseDanmaku.TYPE_SCROLL_RL);
       danmaku.text = "这是一条弹幕" + SystemClock.uptimeMillis();
       danmaku.padding = 5;
       danmaku.priority = 0;
       danmaku.isLive = isLive.valueOf();
       danmaku.setTime(this.model.getCurrentTime() + 1200);
       if (this.mParser) {
         danmaku.textSize = 25 * (this.mParser.getDisplayer().getDensity() * 0.8);
       }
       danmaku.textColor = 0xffff0000;
       danmaku.textShadowColor = 0xffffffff;
       danmaku.borderColor = 0xff00ff00;
       this.model.addDanmaku(danmaku);
     }
   }
   

以上步骤完成后，播放器将可以正常显示视频弹幕。
