           Summary: Jitterbuffer: does not put the same gst timestamp on
                    packets with the same RTP timestamp
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good

Currently, the jitterbuffer does the skew computation idependantly for every
incoming packet. If a large video frame is split into separate packets, they
all have the same RTP timestamp, so they should all have the same GStreamer
timestamp. If the decoder uses the GStreamer timestamp to get the PTS after
decoding, it could get confused (and ffdec_h264 does with the patch attached to
bug #640012).
