Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU): Jetson Orin Nano
• DeepStream Version: 6.4
• JetPack Version (valid for Jetson only): 6.0-b52
• TensorRT Version: 8.6.2

I used the customized resnet10.caffemodel after understanding and plying the inbuilt test apps from the deepstream app. But it shows nothing on the screen display and even the saved output video is blank.

I followed the first part of the link: NVIDIA Deepstream Quickstart. Run full YOLOv4 on a Jetson Nano at 22… | by Victor Sonck | ML6team and downloaded the respective engine files, etc from here:
gtc-2020-demo/deepstream-models/Primary_Detector at master · RidgeRun/gtc-2020-demo · GitHub

When running the config file the app runs successfully but no new screen popup and
even the saved video stream is blank.

I am attaching the logs when I run the app and respective files. Please help me, where I am going wrong.

Okay, the issue related to the display is resolved as I changed the type=3 to type=2 under [sink0] and things work. It displays the output video stream with correct detection with bounding boxes.

but under the [sink0] when type=3, codec=1, and output-file=/opt/nvidia/deepstream/deepstream-6.4/sources/project/data/output_video.h264

the saved output video still shows incorrect results with a blue screen throughout the video stream. can anyone help me with what is going wrong while saving the video?

Thanks.

Have you installed the x264enc plugin? You can try to install that by running the script: user_additional_install.sh in the /opt/nvidia/deepstream/deepstream/ path.

Is not present in the directory /opt/nvidia/deepstream/deepstream-6.4

and I think so x264enc is already installed

t-tech@ubuntu:/opt/nvidia/deepstream/deepstream-6.4$ gst-inspect-1.0 | grep 
x264enc
x264:  x264enc: x264 H.264 Encoder

Yes. This is a bug. We are investigating the bug. Please wait for the new release. Or you can refer to the workaround in Unable to record with deepstream-testsr example on Jetson Orin Nano with DeepStream 6.4 - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums
