No recording file for screen sharing

Hi All,

I am trying to record screen and video streams using-------------
my_stream=Erizo.Stream({audio: my_mic, video: my_cam, screen: my_screen,
data: true, attributes: {name:‘Test’}});

recordingId = id;

however recording file is generated fine for video:true but not for
screen:true (screen captured via screensharing plugin is displaying fine
same as video both local and remote)

erizo log saying starting recording /tmp/xxxxxxx.mkv but there is no file
in /tmp

any help or pointers please?
