           Summary: jitterbuffer in GstBaseRtp fails to handle rtp seqnum
                    rollover
           Product: GStreamer
           Version: 0.10.x
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base

   GNOME milestone: Unspecified


RTP uses a 16bit monotonically increasing sequence number for packet ordering.
Because this counter is small, it rolls over fairly quickly, but the GstBaseRtp
class does not handle this correctly (it always orders lower sequence numbers
as being earlier).

Also, this jitterbuffer in GstBaseRtp is enabled by default. When discussing
this issue with the GstBaseRtp author/maintainer, he said that it shouldn't be
enabled by default.

A patch that fixes both issues follows.
