Other Parts Discussed in Thread: TVP5146M2, DM3730, TVP5146

I want to use tvp5146m2 input 723x579 sizer , crurent dm3730 tvp5146m2 bt565 input sizer 720x579,720x576 is ok.

The omap-resizer to resizer 720x576 input must be 723x579. So i need input 723x579.

Change the tvp514x-int.h,and tvp5146 avid registers

   /* Number of pixels and number of lines per frame for different standards */
   #define NTSC_NUM_ACTIVE_PIXELS (723)
   #define NTSC_NUM_ACTIVE_LINES (483)
   #define PAL_NUM_ACTIVE_PIXELS (723)
   #define PAL_NUM_ACTIVE_LINES (579)

Is this your requirement driver only from resizer point of view?

In any case, don't do this. Resizer driver will take care of it. Are you seeing any issues with default configuration?

Thanks,

Thanks.

Default configuration 576x480->576x480(tvp5146m2 and omap resizer hw accel) is ok,but picture(noise).

The dm3730 datesheet 6.4.7.2.3:

where the input size is X and the output size is Y, three extra input pixels are
required to generate the correct number of output pixels:
X = Y*256/256 + 3 (to account for the extra pixels required for filtering)

I need 576x480 size,so input size must be 579x483.
