           Summary: [REGRESSION] Changing state of a playbin pipeline
                    intensively segfault with several formats
    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: tsaunier at gnome.org
         QAContact: gstreamer-bugs at lists.freedesktop.org

You can for example look at:

https://jenkins.arracacha.collabora.co.uk/view/pitivi/job/gst-validate-tests/757/testReport/validate.file.playback/change_state_intensive/mp3_h264_0_mp4/

This can be reproduced doing doing:

gst-validate-1.0  playbin
uri=file:///home/thiblahute/gst-validate/gst-qa-assets/medias/mp4/raw_h264.0.mp4
--set-scenario change_state_intensive

This same test works reliably with Gst 1.4 so I think it has been introduced
around:

    uridecodebin: Create new sources after chaining up to the parent class

    Otherwise we start the new sources already before the parent class
    got ready to start.
