Summary: decodebin leaks events
Classification: Platform
Product: GStreamer
Version: git
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-base
AssignedTo: gstreamer-bugs at lists.freedesktop.org
ReportedBy: me at andrey-utkin.pp.ua
QAContact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
To reproduce:
ffmpeg -loglevel fatal -t 10 -f lavfi -i testsrc -f mpegts - |
G_SLICE=always-malloc valgrind --suppressions=valgrind.supp --show-reachable=no
gst-launch-1.0 filesrc location=/dev/stdin ! tsdemux ! decodebin ! fakesink

==13884== Using Valgrind-3.8.1 and LibVEX; rerun with -h for copyright info
==13884== Command: gst-launch-1.0 filesrc location=/dev/stdin ! tsdemux !
decodebin ! fakesink

GStreamer has detected that it is running inside valgrind.
It might now take different code paths to ease debugging.
Of course, this may also lead to different bugs.

decodebin dot diagram shows that in this case it consists of typefind,
mpegvideoparse and mpeg2dec. Substituting decodebin with a simple bin with
these elements doesn't reproduce the problem:
