           Summary: memory leak in videomixer2
    Classification: Platform
           Product: GStreamer
           Version: 0.10.30
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

I try run example from videomixer2 :

gst-launch-0.10 \
  videotestsrc pattern=1 ! \
 
video/x-raw-yuv,format=\(fourcc\)AYUV,framerate=\(fraction\)10/1,width=100,height=100
! \
  videobox border-alpha=0 top=-70 bottom=-70 right=-220 ! \
  videomixer2 name=mix sink_0::alpha=0.7 sink_1::alpha=0.5 ! \
  ffmpegcolorspace ! xvimagesink \
  videotestsrc ! \
 
video/x-raw-yuv,format=\(fourcc\)AYUV,framerate=\(fraction\)5/1,width=320,height=240
! mix.

It working, i see picture with colored lines and rectangle with noise; at the
same time process gst-launch eat memory. memory consumption grows untill oom
killer will not  kill the process;

This is especially notable if the output video to fakesink. memory  filled very
quickly (on my system with 2 gigabytes of memory it takes a few minutes)

If i replace videomixer2 by videomixer everything  works well and memory
consumtion remains constant.
