            Bug ID: 773084
           Summary: gstavviddec posts incorrect latency
    Classification: Platform
           Product: GStreamer
           Version: 1.9.90
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-libav
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: jagadishkamathk at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

gstavviddec is always posting single frame latency irrespective of B frames.
Latency would certainly creep in for reordering B picture

Following sender and receiver pipeline can be used to demonstrate the issue

Sender:
gst-launch-1.0 videotestsrc ! video/x-raw,width=320,height=240 ! x264enc
bframes=4 key-int-max=25 b-adapt=0 ! mpegtsmux ! udpsink host=10.0.90.1
port=8000

Receiver:
gst-launch-1.0 udpsrc port=8000 ! tsdemux ! h264parse ! avdec_h264  ! fakesink
sync=1 --gst-debug=basesink:5

The latency seen at basesink at the receiver side is always a single frame
latency(733ms - 700ms belongs to tsdemux)
