Smaple DeepStream-app • 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 am a beginner on DeepStream.
I modified my config file and ran the pre-built Deepstream-app, but the process ends with the following error.
After making deepstream-test1, the output is as follows. This did not run well.
$ ./deepstream-test1-app source_test.txt
Now playing: source_test.txt
