Ever thought it would be possible to zoom in or out your video even while it is playing or may be rotate the screen around. I am sure not even in your dreams. You will be surprised to know that all these are possible while playing media file on your VLC player. To enable this do the following:
Go to Geometry Tab< Enable Magnification/ Zoom Option< Zoom in & Out Option
You will see now see a small window on top left corner of the screen magnification controls. Fill up the space by clicking it to zoom into the video. Now to view the desired video portion, move the square capturing screen across the box. Similarly you can enable the rotate option and start moving the rotary control in the circular direction you want.
