TLDR: I need to build a pipeline that use multiple camera sources, how to I modify my current pipeline to achieve that?

Current pipeline:

NOTE: I can’t use the deepstream app directly since my application need extra functionalities that modifying the config file alone is not enough, thus requiring me to create a custom pipeline as shown above. I’ve checked out other sample apps, the closest to what I need is deepstream test app 3 but that app uses multiple URI sources instead of multiple live sources from cameras. I want to know what plugins/elements I need to add to my current pipeline to use 2 cameras instead 1?

deepstream test app 3 is already a sample for multiple sources. You can just replace the deepstream source bin with your own source bin. DeepStream default source bin is created by create_source_bin(), so you just need to write your own bin create function to replace it.
