Hello Werner, I was wondering whether or not you changed anything in the new firmware that improves the Pan&Scan problem inside menus we discussed a while ago. I just tried the latest firmware under vdr-1.3.23 with the CVS-version of the dvd plugin. But from what I could see the Pan&Scan option still does nothing more than a center-cut-out. Did you change anything in the firmware to improve the display?
No ... what I'm miss is a good documentation about and if or if not this is supported by the DVB cars.
Maybe Johannes knows more about.
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.
