  • 编写播放器
    • 固定视频的宽度和高度(400 X 300)
    • 动态传入影片名字
    • 添加进度控制条
    • 添加关闭视窗的按钮
      my_FLVPlybk.contentPath = _root.moviepath;
      
      onClipEvent (construct)
      {
          aspectRatio = false;
          autoPlay = true;
          autoSize = false;
          contentPath = "\\\"\\\"";
          controllerPolicy = "on";
          controlPlacement = "center";
          fps = 50;
          mediaType = "FLV";
          totalTime = 0;
          enabled = true;
          visible = true;
          minHeight = 300;
          minWidth = 400;
      }
  • 生成播放代码
    • 可配置视频的宽度和高度(来适应播放器的每次修改)
    • 可指定播放器的进度控制条
    • 识别播放flv或swf
    • 指定播放路径(相对路径)

          	 }
          	 
          	 if(moviePath.toLowerCase().indexOf(SWF_FORMAT) == -1 && moviePath.toLowerCase().indexOf(FLV_FORMAT) == -1) {

          	 flashContent = flashContent.replaceAll("%pluginspath%", this.pluginsPath.trim());  //插件即进度控制条

          	 flashContent = flashContent.replaceAll("%flashplayer%", flashPlayer);
          	 
          	 return flashContent;
  • 指定窗口播放
    • 窗口屏幕剧中
    • 用户可关闭窗口
      <span> <img style="vertical-align:middle;" src="pages/images/play.gif" onclick="show_presentation('<%= new FlashManager(AppUtil.getMovieClipPath() + movieInfo.getVideopath()).getHTML()%>');return false;" height="26"/>
      							         			<a style="vertical-align:middle;" title="video" onclick="show_presentation('<%= new FlashManager(AppUtil.getMovieClipPath() + movieInfo.getVideopath()).getHTML()%>');return false;" href="#"><bean:message key="rentalMovieInfoTrailer"/></a> </span>
