Flash视频 Step by Step

• 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) {
        		 return BLANK_CONTENT;

        	 flashContent = flashContent.replaceAll("%height%", this.extraHeight.trim());//影片高度
        	 flashContent = flashContent.replaceAll("%moviepath%", this.moviePath.trim());//播放路径
        	 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>

     
• 视频转化
  • 需要将可供选择的任意视频素材转化为400 * 300的flv.
    • Windows平台,手功转化(Total Video Converter)
    • Linux平台: ffmpeg
  • 传入指定的目录
