Dear collegues,
I'm trying to make my LCCS screen sharing video more sharp. By default it looks a little bit blurry and artifacted.
Documentation on ScreenSharePublisher (http://livedocs.adobe.com/labs/acrobatcom/com/adobe/rtc/collaboration/ScreenSharePublisher.html) says, that ScreenSharePublisher class provides ability of "setting stream properties (frame per second, key frame Interval, qualities etc. Explain in detail in later API section.)"
What is that "Later API section"? I did not find it. Yet I found the following portions of code in the example file named "ScreenSharePublisherFlashOnlyExample.as":
_sspublisher.quality = DEFAULT_SS_QUALITY;
_sspublisher.performance = DEFAULT_SS_PERFORMANCE;
_sspublisher.keyFrameInterval = DEFAULT_SS_KFI;
_sspublisher.fps = DEFAULT_SS_FPS;
_sspublisher.enableHFSS = DEFAULT_SS_ENABLEHFSS;
_sspublisher.bandwidth = DEFAULT_SS_BANDWIDTH;
Here are those constants defined:
protected static const DEFAULT_SS_PERFORMANCE:uint = 70;
protected static const DEFAULT_SS_KFI:uint = 20;
protected static const DEFAULT_SS_FPS:uint = 4;
protected static const DEFAULT_SS_QUALITY:uint = 75;
protected static const DEFAULT_SS_BANDWIDTH:uint = 125000;
protected static const DEFAULT_SS_ENABLEHFSS:Boolean = false;
I've tried to play with the numbers, but the only thing I got is that I could make picture more blurry by setting sspublisher.quality=30. Setting sspublisher.quality to 100,90,80 does not seem to result in better picture. Setting sspublisher.bandwidth=1000000 does not help either, nor the sspublisher.performance=100 or sspublisher.performance=0 does.
Would you please provide the explanation of the picture quality settings for the LCCS screen sharing feature?
