Make deepstream "do something"

[cgame1]

Jetson Xavier agx
jetpack 4.5
deepstream 5.0

how do I use the metadata to “do something”

for example:

I want 1 x GPIO output to go ‘high’ when a “person” is detected on the camera stream.

or when “person” is detected an audio file plays

thanks

Add one pad probe function. You can do anything if the meta data class id is peeson.
