Max-fps Min-fps not proper with fpsdisplaysink in our standalone pipeline

[veeranna]

Hi All,

     We have developed a standalone plugin for HEVC decoder. We ran with
below pipeline
    
    gst-launch-0.10 -v filesrc location=test.265 ! h265decoder ! 
'video/x-raw-yuv, format=(fourcc)I420, framerate=(fraction)30/1,
width=(int)352, height=(int)288' ! ffmpegcolorspace ! fpsdisplaysink

    But we are getting below fps information 
   */GstPipeline:pipeline0/GstFPSDisplaySink:fpsdisplaysink0: last-message =
"Max-fps: -1.00, Min-fps: -1.00*"
    which is not expected .

    Kindly suggest what needs to be done to get the proper fps information
with fpsdisplaysink. 
    As of now, we have not handled any events in h265decoder plugin.If it is
to be handled ,please let us know how to proceed .
    With below pipeline we could observe proper fps information.

   gst-launch-0.10 -v videotestsrc ! fpsdisplaysink


Thanks ,
Veeranna
