[RFC PATCH 2/2] v4l2-utils: extend set-dv-timings to support reduced fps

Extended command line option for set-dv-timings to support timings calculations for reduced fps. This will allow supporting NTSC frame rates like 29.97 or 59.94. Cc: Hans Verkuil Signed-off-by: Prashant Laddha --- utils/v4l2-ctl/v4l2-ctl-stds.cpp | 14 -- 1 file changed, 12 insertio

[RFC PATCH 1/2] v4l2-utils: add support for reduced fps in cvt modeline

Added reduced fps option in cvt timings calculation. In this case, pixel clock is slowed down by a factor of 1000 / 1001 and all other timing parameters are unchanged. With reduced fps option one could generate timings for refresh rates like 29.97 or 59.94. Pixel clock in this case needs better pre
