Hmmm ... the driver in av7110_hw.h knows about
#define VID_NONE_PREF 0x00 /* No aspect ration processing preferred */
#define VID_PAN_SCAN_PREF 0x01 /* Pan and Scan Display preferred */
#define VID_VERT_COMP_PREF 0x02 /* Vertical compression display preferred */
#define VID_VC_AND_PS_PREF 0x03 /* PanScan and vertical Compression if allowed */
#define VID_CENTRE_CUT_PREF 0x05 /* PanScan with zero vector */
but in av7110_av.c it only uses:
VID_PAN_SCAN_PREF for argument VIDEO_PAN_SCAN
VID_VC_AND_PS_PREF for argument VIDEO_LETTER_BOX
VID_CENTRE_CUT_PREF for argument VIDEO_CENTER_CUT_OUT
in the ioctl VIDEO_SET_DISPLAY_FORMAT the rest is EINVAL.
Andre: you may extend the header file
include/linux/dvb/video.h by appending two more
numbers in the enum type video_displayformat_t
and then add the two new cases into the
video ioctl VIDEO_SET_DISPLAY_FORMAT in av7110_av.c
Don't know if this makes a difference. The ioctl
VIDEO_SET_ATTRIBUTES seems to be a nop.
