Screen View pixel scale is difficult in sync with producer's screen whenever it is changing. #34

Open GoogleCodeExporter opened 9 years ago

What steps will reproduce the problem?
1. The source producer can upload part of his screen in whatever Width and 
Height. But the viewer will not know what the figure is.
2. The HTML page of viewer set the screen to be 100% but of the viewer screen, 
not the original streaming video. 
3. pixels on viewer screen are deformed due to the scaling to the view port 
size. The outcome is poor visual quality. 

What is the expected output? What do you see instead?
The view should be able to check the resolution of streaming video then adjust 
its own view port size. The displaying pixel scale must always be 1:1. Or else, 
the viewer swf play should do smart scaling with filter -- that will be more 
complicate of course.  Maybe, the resolution of the crop area should send to 
server, and let viewer re-adjust the viewing area automatically ( at least 
reflect the figure on viewer's parameters on HTML page)

What version of the product are you using? On what operating system?
screenshare-red51RC3.zip, the viewer have been tested on WinXP, Win8 and Win7.

Please provide any additional information below.
Is there any instruction of the parameters parsing to SWF player. I want to use 
flowplayer or HTML5.

Thank
Herrick
