<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi, I'm new here, and I want to ask something about gstreamer: I'm working with a gstreamer application to get the number of dropped frames from a video stream. I use videorate to get the value. But, the result is alway 0, no matter what I tried. The gstreamer qos document says that qos is enabled by default for video, so why I did not get any dropped frame ? I wrote an event prob function to put after the video decoder and found that there's many frame have positive jitter (the diff value got from gst_event_parse_qos()) but they are still not dropped event I set max_lateness for video sink to 100. So, is there anything that I misunderstanding here or did I do anything wrong ? Thanks and best regards. trungnt</td></tr></table> <hr size=1> <a href="http://us.lrd.yahoo.com/_ylc=X3oDMTFnYXY0dG83BHRtX2RtZWNoA1RleHQgTGluawR0bV9sbmsDVTExMDM0NjgEdG1fbmV0A1lhaG9vIQ--/SIG=11ka86nha/**http%3A//downloads.yahoo.com/vn/internetexplorer/"> Lướt web nhanh hơn </a> Internet Explorer 8 tối ưu hóa cho Yahoo!, tự động khởi động 2 trang bạn thích mỗi lần mở trình duyệt. <a href="http://us.lrd.yahoo.com/_ylc=X3oDMTFnYXY0dG83BHRtX2RtZWNoA1RleHQgTGluawR0bV9sbmsDVTExMDM0NjgEdG1fbmV0A1lhaG9vIQ--/SIG=11ka86nha/**http%3A//downloads.yahoo.com/vn/internetexplorer/">Tải IE8 tại đây!
