Could someone try to replace the videotestsrc by v4l2src ? with the exact same pipeline.<br><br>(on win32, with the dshwovideosrc there is the same behaviour)<br><br>Thx.<br><br><div class="gmail_quote">2008/6/16 Tim Müller <<a href="mailto:t.i.m@zen.co.uk">t.i.m@zen.co.uk</a>>:<br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div class="Ih2E3d">> > Is it normal that this pipeline :<br> > > gst-launch-0.10 videotestsrc !
