camera intrinsic sample problem

Autonomous Vehicles DRIVE PX 2 DriveWorks
1

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.

3

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

4

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

5

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

6

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.
