<p class=MsoNormal><span lang=EN-US>Hi, <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I am working on video conference
application using gstreamer framework. In video conference, there might be
multiple screens for video rendering using XvImageSink. I found that although some
window is obscured ( for example full screen mode), its related XvImageSink is
still busy on calling gst_xvimagesink_show_frame for video rendering. I am
wondering that we could have optimization to detect additional “Obscured”
xevent and reduce the rendering frequency to very low value, like 1 fps, if
such window is obscured. In this way, we can save precious resources for most
applications, like CPU and power, at the same time, having minimal impact to
end user. Does that approach make sense? What do you guys think of it? Thanks a
lot for your feedback and comments.<o:p></o:p></span></p>
