For example, if t0 is the current time and N is the start time in seconds that means recording will start from t0 N. For it to work, the video cache size must be greater than the N. smart-rec-default-duration= How to extend this to work with multiple sources? How can I run the DeepStream sample application in debug mode? There are two ways in which smart record events can be generated - either through local events or through cloud messages. Add this bin after the audio/video parser element in the pipeline. The deepstream-test2 progresses from test1 and cascades secondary network to the primary network. What happens if unsupported fields are added into each section of the YAML file? DeepStream supports application development in C/C++ and in Python through the Python bindings.
