Hi, thanks for your reply. I fiddled a little bit around with this.
It's pretty easy to stretch the image vertically to full screen. You just need to set echo 640,480 > /sys/devices/platform/omapdss/overlay2/output_size and echo 42,30 > /sys/devices/platform/omapdss/overlay2/position The media player does the same. The problem is the horizontal stretch. You can't write to /sys/devices/platform/omapdss/overlay2/input_size and by checking what the media player does i found out that it actually changes this to 640x480 when playing a 4:3 video. Unfortunately the /sys interface doesn't allow to write these, so i'll have a look at the ioctls next.
