--- Comment #9 from Florent Thiéry <florent.thiery at ubicast.eu> ---
I am trying to run this until it fails, but of course this is a race condition,
valgrind may be slowing it so much that the problem may not happen again.

If i ever get it, is the following good enough or is a leak report necessary ?

$ while valgrind gst-launch-1.0 filesrc location=/tmp/sample.h264 ! tee
name=tee ! queue ! fakesink tee. ! queue ! h264parse ! vaapih264dec !
vaapipostproc ! "video/x-raw, format=(string)NV12, width=(int)1280,
height=(int)720, framerate=(fraction)30" ! fakesink tee. ! queue ! h264parse !
vaapih264dec ! vaapipostproc ! "video/x-raw, format=(string)NV12,
width=(int)1280, height=(int)720, framerate=(fraction)30" ! fakesink tee. !
queue ! h264parse ! vaapih264dec ! vaapipostproc ! "video/x-raw,
format=(string)NV12, width=(int)1280, height=(int)720, framerate=(fraction)30"
