question
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
I just run python app example and got this error, don’t know why. DeepStream c api works well. But python bindings cannot run with saved video with my custom code and its CSI or USB camera app.
Here is the o/p:
