I have multiple video analytics pipeline created using deepsteam python apps. But I want to include all those in single script and launch. sometimes I will switch to pipeline 1 or 2 or 3 (for example: 3 pipelines). How should I solve this problem ?

Reference: I have searched, found this page. Please tell me if this is the correct way to approach this or any other approach could also work ?

sometimes I will switch to pipeline 1 or 2 or 3 (for example: 3 pipelines).

What does this mean?

[curiousfrog]

I want to select which pipeline to use at a particular moment. For example, just Video display, sometimes video analytics basically want to switch according to requirement

If your display sink support dynamic hide and display, you can rely on the function.

If it is not, you need to dynamically connect and disconnect you display sink to the pipelines. It is basic gstreamer coding skills. GStreamer: open source multimedia framework It has nothing to do with deepstream.

How to know if display sink support dynamic hide and display ?
and I have tried with multiple sink, it’s getting really slow, and at the same I don’t want all displays, just one at a time.

It is not deepstream related. You need to find your own solution.
