Hi, what application are you trying to use,

For example if you capture to file in 720p you may use videoscale

videoscale ! "video/x-raw-yuv,width=1282,height=720  in this example sequence

gst-launch -e v4l2src ! "video/x-raw-yuv, width=1920 , height= 1080,framerate=30/1" ! queue ! ffmpegcolorspace ! 
ducatih264enc <  > ! h264parse ! qtmux ! filesink location=sample.mp4

My application needs to switch between 720p and 1080p during running, so I only allocate the 1080p memory, 720p also uses this memory, but I do not know how to set the ducatih264 parameters when the resolution is 720p.I know this need to crop,how to?

Hi Achun,

What you need to do is not crop but scale, as I showed in my previous post.
