How to check inference time for a frame when using deepstream

You could add time stamp print before and after sources/libs/nvdsinfer/nvdsinfer_context_impl.cpp::NvDsInferContextImpl::queueInputBatch RETURN_NVINFER_ERROR(m_BackendContext->enqueueBuffer(backendBuffer, *m_InferStream, m_InputConsumedEvent.get()), “Infer context enqueue buffer failed”); like this, struct timeval start, stop; gettimeofday(&start, NULL); RETURN_NVINFER_ERROR(m_BackendContext->enqueueBuffer(backendBuffer, *m_InferStream, m_InputConsumedEvent.get()…

print inference time, It is working.
I have also added a counter to represent number of frames processed. I found out that with “deepstream-app -c” all the frames in input source are not processed.
For example I gave video input with 442 frames but the logs i printed came out only for 229 frames.
I had set interval=0 in the config file that I provided.

Although when I run my custom detector parser with reference code deepstream-test3 source code example with same input video source all the frames were processed.

Is there a way I can process all the frames for nvinfer in deepstream-app ?

I can get all the frames printed, can you specify more details how to repro your issue?

I have found out the issue, my batch size was not set to 1. I had given 1 video input, when I gave batch size=1 then it processed all frames, Could that be the reason?

I do not think so, i have multi videos, all processed. please check further.
