title: How to change the resolution of image in gstbuffer?
body: <p>I am receiving data over UDP, </p>
  
  <p>In Pullbuffer callback function of appsink, am retrieving the data into gstbuffer.</p>
  
  <p>but that data is of 1920X1080 image buffers.</p>
  
  <p>But, i would like to convert then into 720X576 resolution and stream that data.</p>
  
  <p>How can i do this using gstreamer?</p>
