           Summary: theoraenc: spurious encoder resets due to unstable
                    upstream timestamps cause quality issues
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: vincent.penquerch at collabora.co.uk
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


When incoming timestamps are off by more than three quarters of a frame
duration, theoraenc resets the encoder state and emits a discontinuity.

Would be better to increase that tolerance a lot (and maybe make it a
property), and reemit the last frame (if available) enough times to make up for
the gap, which will let libtheora emit drop frames.
