Hello

how to disable video preview on screen while playin video , , sometime i stream my video clips to my car thru FM TR , but the battery ends too soon . i thought if there way to disable video preview on the screen that would save some power . it going be like just an audio file but its video. there was a script to record video while no image shown on the screen i believe the script was called pycam , So it could be done to playing video while screen is dim, now if i simple switch screen off while video is playing then the video will stop >
