           Summary: videomixer stops working if more than one sinkpads
                    exist.
    Classification: Platform
           Product: GStreamer
           Version: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: hannesb at gmx.de

     GNOME version: ---


I wanted to construct a pipeline that displays the output of videomixer and
writes a file. As soon as a second sinkpad is connected to the "tee", it stops
rendering.

This one her works (nearly the same as the example):
gst-launch videotestsrc pattern=1 ! tee name=t1 ! queue ! video/x-raw-rgb,
framerate=\(fraction\)10/1, width=100, height=100 !   videomixer name=mix !
ffmpegcolorspace ! ximagesink   videotestsrc !    video/x-raw-rgb,
framerate=\(fraction\)5/1, width=320, height=240 ! mix.

But as soon as I add "t1. ! queue ! fakesink" to the call above it does not
overlay anymore.
I even can jam it with an additional "fakesrc ! fakesink"

Checked with 0.10.30 as well as with a quite new git.
The same happens if I use videomixer2 instead.
