This command worked in the end: `ffmpeg -i https://192.168.11.139:8080/video -i /dev/video3 -filter_complex '[0:v]setpts=(RTCTIME-RTCSTART)/(TB*1000000),scale=iw*4/3:-1,crop=1280:720[cam];[1:v]scale=4*iw:-1:flags=neighbor[calc];[cam][calc]overlay' -vcodec rawvideo -pix_fmt yuv420p -f v4l2 /dev/video2` Thanks again On Mon, Jan 25, 2021 at 12:59 AM Carl Eugen Hoyos <ceffm...@gmail.com> wrote: > Am Mo., 25.
