Hi @Kiran-38, can you let us know the platform and your settings? If you are running the .net core app on Windows, please make sure you run Config.bat first. https://github.com/microsoft/Microsoft-Rocket-Video-Analytics-Platform#build-on-windows

Hi @ycshu086, thanks for your response.
I am running on ubuntu 16.04 on a docker instance, before building my docker image I have run the config.sh file but I got this problem.

Hi @Kiran-38, does the pre-built image work for you? docker pull ycshu086/rocket-sample-edgeonly:0.1 Also, was a media file (e.g., *.mp4) included in /media before you run docker build?

Hi @ycshu086, yes pre-built image works for me. But when I tried to give any url streaming it gives me error: (-2) GStreamer: your gstreamer installation is missing a required plugin
