By the way, I have found the H264 stream:sample_1080p_h264.mp4 in DeepStream Development Guide

Now I run with following command for C++ example
./deepstream-test1-app sample_1080p_h264.mp4

It run without error but it stucks without any output.

Any suggestion?

Thanks

Actually the window does show the errors:

INFO: …/nvdsinfer/nvdsinfer_func_utils.cpp:39 [TRT]: Detected 1 inputs and 2 output network tensors.

It seems that it cannot find resnet10.caffemodel_b1_gpu0_int8.engine file

Now after I used the binary file (.h264) rather the .mp4 file, then the program runs fine.

./deepstream-test1-app /opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_qHD.h264
