In case the input RTSP’s fps is greater than the deepstream binary’s fps, then I’m observing jitter for fast-moving objects in the frame as in the below images.

I’m using deepstream-app, this issue is encountered in both

  • the original input frames that I extract from deepstream in probe function
  • the output video that is saved

If I decrease the fps of input RTSP s.t. it’s less than deepstream fps, this issue doesn’t arise.

From the picture you posted here. It is caused by packets lost through RTSP.

4

How can I solve this issue? I don’t see it if I play the original RTSP stream.

5

Either improve deepstream app FPS or reduce the input RTSP FPS.

6

yeah, I had reduced the RTSP fps to handle this problem, is there any other way, possibly in deepstream?
