I just installed JetPack 4.2.2. and DeepStream 4.0 for Jetson. And run a deepstream-test1-app but didn’t work. Here is error message.

Hi YodaPaPa, From log error is show failed to load config file.

I’m using the Deepstream 4.x I had the same problem… you must go to : “/opt/nvidia/deepstream-4.0/sources/apps/sample\_apps/deepstream-test1” over there u will see a bunch of files: c file dstest1\_pgie\_config.txt a Make file a readme file you compile by just typing : make normally you should see a new file. then you run: ./deepstream-test1-app /opt/nvidia/deepstream/deepstream-4.0/samples/streams/sample\_720p.h264 " et voilà!" hope it helps - for me it did ---
