Report some issues

I've executed this app however I've faced some issues as follows:

1. there is a wrong file path into deepstream_dewarper_test.c:

$ git diff
diff --git a/deepstream_dewarper_test.c b/deepstream_dewarper_test.c
index 9c65f7a..412b52e 100755

2. Failed to parse UFF model:

Then I fixed inference_files/config_infer_primary_peoplenet.txt as bellow:

Then I've faced "Segmentation fault" after executing this application.

3. Segmentation fault:

It would be nice if you have solutions. Thank you.

Hi @yosukehara , thanks for reporting these issues. The first two are solved on the latest update. For the segmentation fault issue, I run the app again and it's working fine. But I will see if I can reproduce your error with different settings. You should hear from me soon. What is the jetpack version you are using?

Thank you for your support. But I still have the same situation.

What is the jetpack version you are using?

I'm using the latest version, 4.5.1.

Thank you.

Hi @yosukehara , sorry for the late reply. Can you please try it now. The issue was related to the OSD_SINK_PAD_BUFFER. I tried it on different platforms and it seems to be working now. Please let me know if you still have an issue. And thanks for pointing it out.

@MikyasDesta Thanks a lot. It works fine.
