            Bug ID: 745151
           Summary: videofilter: Added a new plugin to enhance video in NV
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org

Input and Output images

Added a new filter which enhances video in NV format. This uses contrast
stretching and Convolution internally to achieve the required output.

This is tested by using below pipeline

gst-launch-1.0 filesrc location=pm.mp4 ! decodebin ! videoconvert ! enhance !
videoconvert ! ximagesink

gst-launch-1.0 -v videotestsrc ! videoconvert ! enhance ! videoconvert !

I have attached the input and output images to see the result. Left image is
original and right image is output

This patch is important as gStreamer does not have convolution implemented yet.
Convolution implemented in this patch takes kernel input, so just by passing
different kernels its possible to achieve a number of good video filters which
are quite essential for most of the video based applications.
