camera intrinsic sample problem

when I excute the camera intrinsic-constraints sample, not working.

in detail, when i execute the command below,

sudo ./calibration-intrinsics-constraints --use-checkerboard=11x8 --input-video=/usr/local/driveworks/data/tools/calibration/graph/intrinsics/video_A0_FC120.h264 --output=~/camera.json

the video window is shown. but fps is very low (about 0.3 fps), and(but) it look like paused.

one thing some strange is this message.

[08-07-2019 13:06:49] CameraVirtualNvMedia: no seek table found at /usr/local/driveworks/data/tools/calibration/graph/intrinsics/video_A0_FC120.h264.seek, seeking is not available.

is there anyone who have same symptom?? (Driveworks 2.0.2)

sudo ./calibration-intrinsics-constraints --use-checkerboard=11x8 --input-video=/usr/local/driveworks/data/tools/calibration/graph/intrinsics/video_A0_FC120.h264 --output=~/camera.json

Dear jw31,
Could you please share required data and steps to reproduce this on our end. I assume you are using our latest DRIVE release for DRIVE PX 2.

I just installed SDK and execute the sample what NVIDIA provided.

Dear jw31,
We will look into it and get back to you

Dear jw31,
This latency is expected on board. Could you please check running on x86 machine.

we checked on x86 machine, and I works(fps is about 10)

so you mean that the latency on board is no problem??

Dear jw31,
It is not a problem as it is expected to run on x86 machine.
