            Bug ID: 795327
           Summary: "rfbsrc" linked to "videorate" causes error "invalid
                    buffer size 4096 < 4196352"
    Classification: Platform
           Product: GStreamer
           Version: 1.14.0
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad

The pipeline

gst-launch-1.0.exe rfbsrc host="localhost" port=5900 password=pass ! videorate
! video/x-raw,framerate=10/1 ! videoconvert ! jpegenc ! fakesink

not working due some issues between rfbsrc and videorate . 
The pipeline works if I remove "videorate" with caps or just replace rfbsrc by
videotestsrc

Debug details are below:

D:\gstreamer\1.0\x86_64\bin>gst-launch-1.0.exe rfbsrc host="localhost"
port=5900 password=pass ! videorate ! video/x-raw,framerate=10/1 ! videoconvert
! jpegenc ! fakesink
