           Summary: [oggdemux] Occasional failure to seek in push mode
    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

     GNOME version: ---


Sometimes, when receiving a seek request, oggdemux will not have a chain and
will ignore the seek. I think this can happen when it's not built its chain
yet.
Subsequent seeks will work once the chain is ready.
This may or may not be related to oggdemux attempting to seek to the end to
determine stream length.

Short debug log from GST_DEBUG=ogg*:5 showing this follows at the end, obtained
from the Insanity http test on an Ogg file, with command line:
