Hi,
The example is using a filesink so you will get a file output rather than a display.
For example, we can get a Pose_Estimation.mp4 file when running the following command.
Please make sure the deepstream-pose-estimation-app has the authority to write the file in the output folder
# ./deepstream-pose-estimation-app <file-uri> <output-path>
$ ./deepstream-pose-estimation-app /opt/nvidia/deepstream/deepstream-6.0/samples/streams/sample_720p.h264 ./
Thanks.
