前端，视频直播开发时，js和flash交互时（底层as代码以写好），本地摄像头显示很模糊。怎么设置参数修改flash

var flashvars = {};

flashvars.id = this.id;
console.log(this.width,this.height);
flashvars.width = this.width;
flashvars.height = this.height;
flashvars.on_publisher_ready = "__srs_on_publisher_ready";
flashvars.on_publisher_error = "__srs_on_publisher_error";
flashvars.on_publisher_warn = "__srs_on_publisher_warn";

var params = {};
params.wmode = "opaque";
params.allowFullScreen = "true";
params.allowScriptAccess = "always";
params.quality="high";
var attributes = {};

var self = this;

swfobject.embedSWF(
    "srs_publisher/release/srs_publisher.swf?_version="+srs_get_version_code(), 
    this.container,
    this.width, this.height,
    "11.1.0", "js/AdobeFlashPlayerInstall.swf",
    flashvars, params, attributes,
    function(callbackObj){
        self.callbackObj = callbackObj;
    }
);


****参数怎么设置？具体的参数都可以怎么查找学习？网上学习资料没找到.****
