I'm using Raspbmc to display video from a security camera. The camera outputs 1280x720. I'm outputting the video from the Pi to a small (4") widescreen format LCD through the Pi's NTSC(RCA) port. The video from the camera is normally letterboxed on that little screen, but changing the zoom to "View mode - Stretch 4:3" makes it fill the LCD exactly the way I want. My video stream plays automatically via the autoexec.py when the Pi boots up. Is there a way for me to automatically set the zoom level either in my autoexec.py or in the .strm file that plays in the autoexec? Thanks!
