ffmpe         


        

Answer 1

This can be done without using x11grab/xcbgrab/gdigrab with help of the below commands in linux .

To record a video,

 ffmpeg -f x11grab  -s 1366x768 -i :0.0 -r 25 -vcodec libx264  output.mkv

To record a frame,

./ffmpeg -f fbdev -framerate 1 -i /dev/fb1 -frames:v 1 screenshot3.jpeg
