I am trying to use jpg image but it wont work and gives me the following error:

But what pipeline you run?

6

This is my pipeline:

embedding_vector.txt (1.3 KB)
config_infer_primary_yoloV8.txt (716 Bytes)

7

This looks like config files for nvinfer, not a pipeline description.

8

this is the pipeline:

embedding_vector.txt (1.3 KB)

9

uri=file://13.jpg

Try using absolute path， such as file:///absolute path/13.jpg

I tried that as well and its not working.
Still the same error:

Since I don’t have your test images and models, I modified the configuration items like below.

The deepstream-app can work normally.

Please check if there is a problem with your model.

uri=file:///opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.jpg

config-file=/opt/nvidia/deepstream/deepstream/sources/apps/sample_apps/deepstream-test1/dstest1_pgie_config.txt
12

that’s weird! it worked for the sample images:
uri=file:///opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.jpg

But did not worked for my image. Both of them are jpeg.

What might be the problem?

I am not sure, can you share the picture?

for this, its just show the image without the the bboxes and the detected objects.

16

At the moment I’m not sure if it’s a bug or a limitation.

You can first try to use the following command to convert

ffmpeg -i 13.jpg 1.jpg

Your image is a Progressive JPEG Image and needs to be converted to baseline.
In fact after converting, I can get bbox

17

Only baseline is supported, you need to use the above method to transcode.
