how to adjust brightness etc . in web page with vlc activex
Posted: 20 Oct 2006 17:50
I have streamed mpg file in web page embedded with vlc0.8.5 activex;
Now I wanna adjust image effective realtime,such as brightness,contrast,hue,saturation etc.
But I still face to failure after many efforts to use vlc activex method : setVariable() .
well , the follow javascript can adjust image effective:
var options = new Array(":vout-filter=adjust", ":hue=120"); document.vlc.addTarget(TargetUrl, options, 4+8, -666);
but not what I need!
I used setVariable() method as follows:
var hstr="hue";
var hvalue=120;
document.vlc.setVariable(hstr,hvalue);
or
var hstr="hue";
var hvalue;
document.vlc.getVariable(hstr,hvalue);
document.vlc.setVariable(hstr,hvalue);
document.write("ok");
but nothing to happen
who can help me ? thanks in advance!
