stream video from rtsp with frame rate of 1 fps

Question

i am trying to stream only one frame per second from rtsp , I am using ffmpeg with following command

ffmpeg.exe -i rtsp:/XXXXX -q:v 1 -vf fps=fps=1 -f mpegts udp://Y.Y.Y.Y:ZZ

but i receive higher rate than 1 fps.

P.S Capturing frame in 1 fps and saving it in any other method (not images) will fix the problem also

Answer 1

Use the realtime filter.

ffmpeg -i rtsp:/XXXXX -q:v 1 -vf fps=1,realtime -f mpegts udp://Y.Y.Y.Y:ZZ

If you have audio, you will need to add -af arealtime.
