Bug ID: 753080
Summary: queue2: Doesn't push the flush stop on it's thread
Classification: Platform
Product: GStreamer
Version: git master
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gstreamer (core)
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: olivier.crete at ocrete.ca
QA Contact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
I have this backtrace where a flush stop event from a demuxer ends push making
a stick stream-start be pushed down and then get's stuck in playsink's pad
probe. So it causes a deadlock.
I'm attaching a patch that just makes queue2 put the flush-stop in the queue,
but I guess the other option would be to make playsink's probe drop stick
events and just wait for buffer/gap before continuing.
My test is:
