Deepstream_test_3.py stop working

deepstream python apps. I am using deepstream_test_3.py to run 4 rtsp cameras. If one camera down, the program stop. Unlike deepstream-app, if one down the program continue to run. Is there a way to make deepstream_test_3.py continue to run even if one camera is down.

@tmrngo2012 From the log, the deepstream_test_3.py failed with rtsp link error. If the rtsp stream ends normally, deepstream_test_3.py will not be impacted. You may need to add your own codes to handle such error.
