Hi, I’m using deepstream-test5-app. I enable dsexample plugin to save frames to file using this method [image] How to crop the image and save DeepStream SDK Hi, Please refer to the following sample: static GstFlowReturn get_converted_mat (GstDsExample * dsexample, NvBuf…

Hi, We have a new sample in DS5.0: deepstream-5.0\sources\apps\sample_apps\deepstream-image-meta-test It is close to your usecase. Please take a look.

Hi, deepstream-test5-app is based on deepstream-app and you can check the architecture . When you enable dsexample, it links like: ... ! nvinfer ! dsexample ! nvtracker ! ... If you needs to have bounding boxes, you have to check the source code and customize it into ... ! nvdsosd ! dsexample ! …

@DaneLLL thanks very much for helping. Actually I want to draw bounding box on frames only when I need to. So far I use msgconv and msgbroker to send metadata to kafka, which has some unique key value like uuid or timestamp. Is there any method to match uuid or timestamp with frames in dsexample? …

I can access frame_meta->ntp_timestamp in dsexample, but it’s always 0. When will them frame meta get timestamp in the pipeline?

Can you suggest how to save the complete frame with bounding boxes instead of cropped objects. I am able to run deepstream-image-meta-test and generate the cropped images.

Thanks. Can you please high level steps so that I can give it a try. I am not sure where to put this code. Appreciate your help.

Hi, [image] Mike: Can you please high level steps so that I can give it a try. I am not sure where to put this code. There is a prob function in source pad of nvdsanalytics. In first step, you can duplicate it to source pad of nvdsosd.
