[Freeswitch-users] video_avatar_png doesn't work

Hi all, I am trying to use video_avatar_png in my dialplan so that I want all the participants entering the conference to display this png image on their behalf to other participants in conference. However, I dont see the image being played. It doesn't display the video either. Rather it just displays the background image I have configured in the layout. I am using the below in my dialplan. <action application="set" data="video_avatar_png=/usr/local/freeswitch/conf/CallOnHold.png"/> Please help on what am I doing wrong here. Thanks Ramesh
