Hi

I am facing a issue when my input sorce is RTSP and I am enabling the Tacker it giving error,
But if input sorce is a mp4 file and enable the tracker its working fine

[source0]
enable=1
#Type - 1=CameraV4L2 2=URI 3=MultiURI 4=RTSP
type=4
uri=rtsp://<>:554
num-sources=1
gpu-id=0
cudadec-memtype=0

[tracker]
enable=1
tracker-width=480
tracker-height=272
enable-batch-proces = 1
ll-lib-file=/opt/nvidia/deepstream/deepstream-4.0/lib/libnvds_mot_klt.so
gpu-id=0

Also If I disbale the tracker then RTSP works fine with no issue

Please suggest some pointers to solve this issue.

Hi Kayccc,

Thanks for sharing the patched libs, I have applied the same, It’s fixed the issue but now the overall FPS has gone heavily down !!

Please let me know what else need to do on this !!
