Summary: queue element fails to re-negotiate caps upstream when
sink windows resize
Version: HEAD CVS
Component: gstreamer (core)
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: edgard.lima at indt.org.br
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: Unspecified
GNOME milestone: Unspecified
to see the bug, just try the last pipeline listed bellow then resize the
windows with your mouse.
if you try like this "v4l2src ! queue ! ffmpegcolorspace ! ximagesink"
or "v4l2src ! queue ! ffmpegcolorspace ! identity ! ximagesink"
neither ffmpegcolorspace or identity accept the new size and the
ximagesink just put a black area and everything works fine
trying this: gst-launch v4l2src ! ffmpegcolorspace ! queue ! ximagesink
when you resize it seems the queue re-negotiate the caps with ximagesink
and then try to re-negotiate with ffmpegcolorspace which tries to
re-negotiate with v4l2src that can't work in a size like 645x483 for example
