hi! I'd like to capture the TOP and BOTTOM field but not with the V4L2_FIELD_SEQ_TB. I need it in two separate buffer not in one. I think the V4L2_FIELD_ANY should be assigned to this feature, but now it is mapped to the bottom field only. if (V4L2_FIELD_ANY == field) field = (f->fmt.pix.height > maxh/2) ? V4L2_FIELD_INTERLACED : V4L2_FIELD_BOTTOM; I tried to do the following it the irq handler (just a silly idea) but the machine hanged, I guess the RISC memory for the TOP field is not filled: if (o_top) capture->vb.field=V4L2_FIELD_BOTTOM; else capture->vb.field=V4L2_FIELD_TOP; if (V4L2_FIELD_HAS_TOP(capture->vb.field)) btv->top = capture; if (V4L2_FIELD_HAS_BOTTOM(capture->vb.field)) btv->bottom = capture; Is this feature is planned to have in the near future? gabor
