Forum Post: RE: Sample Aspect Ratio

I Found sclrPrm.outScaleFactor.ratio.widthRatio / heightRatio in multich_progressive_vcap_venc_vdec_vdis.c

sclrPrm.scaleMode                                                      = DEI_SCALE_MODE_RATIO; sclrPrm.outScaleFactor.ratio.widthRatio.numerator    = 1; sclrPrm.outScaleFactor.ratio.widthRatio.denominator  = 2; sclrPrm.outScaleFactor.ratio.heightRatio.numerator   = 1; sclrPrm.outScaleFactor.ratio.heightRatio.denominator = 1; sclrPrm.numBufsPerCh                                               = 2;

How can we set 4:3 or 16:9 ratio or other ratios for SD video output and independently for HDMI video output ?

 Is it possible to set this dynamicly ?
