            Bug ID: 748054
           Summary: avfvideosrc: starting capture session too early,
                    sending buffers with PTS=NONE
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: All
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: ilya.konstantinov at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

avfvideosrc starts the capture session earlier than PLAYING, and sample buffers
that arrive before element has clock are stamped with pts=GST_CLOCK_TIME_NONE.

Whether or not we're interested in starting session early (for whatever
reason...), we should not send out those buffers.

After http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/commit/?
id=5bc17dac295da9ec33c05b42ddac41b61bfaaaba, we now don't try to use clock
anymore, but we still end up sending buffers with pts=GST_CLOCK_TIME_NONE which
seems bogus.
