<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 multimedia application
development using gstreamer framework. There might be many cases that some
window is invisible (for example other window is in full screen), 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>
