  7 décembre 2013, par henrycharles

  I am new to multimedia.I want to make a project for live video chat in java. Googling around I found about Xuggler.I successfully downloaded all the jars given in this How do you install the latest version of Xuggler (5.4, as of 18/05/2013) in eclipse ? .

  

  and tried executing sample code from http://www.javacodegeeks.com/2011/02/xuggler-tutorial-frames-capture-video.html I am not getting any compilation error but the following runtime error. Any help would be much appreciated.
